Use when starting, planning, or reviewing a new-harness project. Covers the readiness audit of prior art, the spike-first milestone plan, the full integration-surface checklist, the per-harness variance axes to probe, and the process/communication contract with Mahmoud. Living document: every harness project appends its lessons to resources/LESSONS.md. +--- + +# Add a harness to Agenta + +A harness is the coding-agent program Agenta runs on behalf of a user (Pi, Claude +Code, Codex, ...). This skill encodes how we add one: what to build, in what order, +what to probe empirically first, and how to run the project so Mahmoud can steer it. +It was extracted from the Codex harness project (2026-07, `docs/design/codex-harness/` +in that project's worktree) and grows with every subsequent harness. + +Read `resources/LESSONS.md` after this file: it is the append-only log of things that +surprised us, per harness. If you are about to start a new harness project, the +combination of this file plus the lessons log IS the project template. + +## Step 0: audit prior art before writing anything + +If a draft PR or old branch exists for this harness, do a readiness audit first and +assume salvage, not rebase. Judge it on five axes: permissions, human-in-the-loop +approvals, Agenta tool delivery, event/streaming protocol, auth modes. Then measure +rebase distance not in commits but in structure: have the files it touches been +split, renamed, or re-contracted on main? (The Codex drafts were 1,450 commits behind +and their central wiring file had been exploded into eleven modules; the SDK adapter +skeleton survived, everything else was rewritten.) Deliver the audit as a +salvage/rewrite/discard table before proposing a plan. + +## Step 1: check what the daemon already does + +The runner executes harnesses through the pinned `sandbox-agent` npm daemon, which +spawns each harness behind an ACP (Agent Client Protocol) bridge. Before assuming you +must build a runtime: read the daemon's embedded adapter registry (in the pinned +package under `services/runner/node_modules/sandbox-agent`, plus the repo's patch +file) for the harness name, the bridge package it maps to, the credential probe it +runs, and its embedded model default. For Codex the daemon already knew how to +install the CLI and bridge; the whole project was config, credentials, permissions, +and approvals plumbing. If the daemon does NOT support the harness, that is a +different, much larger project (a daemon/bridge contribution) and the plan must say +so explicitly. + +## Step 2: spike before design (Checkpoint 1 gate) + +Run a throwaway spike against the real daemon before writing production code. The +four standard questions, refined per harness: + +1. **Approvals shape.** Does the harness's ACP bridge raise permission requests? + Under which of the harness's native permission settings? Record the exact frame + shape; the runner classifies approval gates per harness in a closed union + (`acp-interactions.ts`), so a new gate type needs the real frames. +2. **Config split.** Where does the harness read its config? Can its home/config + directory variable separate login state (mounted, read-write) from per-run config + (rendered fresh)? This decides the mount layout, which is a Mahmoud decision. +3. **Tool delivery.** Can the runner's internal `agenta-tools` MCP server reach the + harness, over which channel (ACP session params vs config file), and can specific + tools be pre-allowed/denied natively (the F-046 question: an "allow" tool must run + without pausing)? +4. **Auth mechanisms, enumerated from source.** Do NOT probe a candidate list of + credential forms and stop at the first that works; that satisficing locked the + Codex project into a file-based design for three milestones while a file-free + mechanism sat one function away. Instead: find the harness's credential + RESOLUTION/PRECEDENCE function in its source at the pinned version and read it + top to bottom; precedence functions are small and enumerate the whole mechanism + space by construction. Table every branch (env-at-request-time, files, stores, + login flows), then probe the promising ones through the daemon path. The same + rule applies to any capability that shapes a design: config delivery, state + location, continuity. Also determine what the subscription sidecar must produce. + +Everything unverified in the design stays marked "TO VERIFY IN SPIKE" until the spike +answers it with a saved transcript. The spike ends in a findings memo plus a decision +register, and the project stops at **Checkpoint 1**: Mahmoud rules on the mount +layout, the human-in-the-loop posture, and the handling of anything the harness +cannot express, before milestones that depend on those answers start. + +## The integration surface (what every harness touches) + +SDK (`sdks/python/agenta/sdk/agents/`): +- `HarnessType` value, identity entry, `supported_harnesses`. +- An adapter class in `adapters/harnesses.py` mirroring `ClaudeHarness` + (`_to_harness_config`, drop-with-warning for Pi builtins). +- A `_settings.py` sibling of `claude_settings.py` when the harness takes a + config file: author's harness-native options pass through verbatim (Layer 1), plus + derived reinforcement rules from the sandbox boundary (Layer 2) and per-MCP-server + and per-tool permissions (Layer 3).

Protocol path: behind the shared ACP daemon (cheap) vs native protocol (expensive). +2. Permission vocabulary: fine-grained per-tool rules (Claude) vs coarse global modes + (Codex). Coarse vocabularies raise expressibility questions that go to the + decision register, never get silently approximated. +3. Config layout: separate login dir and project config (Claude) vs one directory for + both (Codex). One-directory harnesses make the mount layout a real design. +4.

Codex writes SQLite state + (`goals_*.sqlite` + `-wal`/`-shm`, `logs_*.sqlite`) into `$CODEX_HOME`.

The + Milestone 0 spike ran the daemon with `CODEX_HOME` on a plain tmp dir, so it never + saw this; the durable mount is only exercised in a real session run. Lesson: for any + new harness, verify its HOME/state directory on the ACTUAL durable-mount filesystem + (geesefs/Daytona), not a local tmp dir, before approving a mount layout that places + state on the session cwd. This invalidated the premise of D-002 Option A and is a + Checkpoint decision, not a code fix to make unilaterally. +- 2026-07-24 · **The harness's own state-dir env override is the fix, not a mount rework.** + Follow-up to the SQLite-on-geesefs wedge above: codex exposes `CODEX_SQLITE_HOME` + (upstream `codex-rs/state/src/lib.rs`), which relocates ALL of its SQLite families off + `CODEX_HOME` while native `session/load` resume rides the plain `sessions/` rollout jsonl + that stays on the durable home. Keeping `CODEX_HOME` on the durable mount and pointing + `CODEX_SQLITE_HOME` at a local off-mount dir fixed the M1 durable multi-turn run (codeword + survived turn to turn, no hang). Lessons for the next harness: (1) before reworking the + mount layout, look for an upstream env/config knob that moves just the mount-hostile state + (SQLite/WAL) off the durable filesystem; harnesses that keep append-only rollout files + separate from their SQLite make this clean. (2) The off-mount state dir must be + per-session-stable (derive it from `basename(cwd)` like `relayDir`) so it does not churn + the daemon config fingerprint and kill warm reuse; keep it OUT of fingerprint inputs and + clean it best-effort on destroy (the SQLite is disposable; resume does not need it). +- 2026-07-24 · **git-on-geesefs is a real but often benign residual risk.** Codex clones a + plugins repo under `$CODEX_HOME/.tmp/plugins` at session start. On geesefs, git's hardlink + attempts fail (`CreateLinkOp: function not implemented`), but git degrades gracefully and + the turn completes. Watch for it when a new harness does VCS/hardlink work on a mounted + home; confirm it is non-fatal rather than assuming, and note there may be no upstream knob + to redirect a harness's tmp/scratch dir if it ever turns fatal. + +## Milestone 2 (Agenta tools + pricing) + +- 2026-07-24 · **Run cost comes from litellm keyed by the SPAN model, not the curated catalog.** + The platform cost calc (`api .../tracing/utils/trees.py calculate_costs`) calls + `litellm.cost_per_token(model=...)`, reading the model from `ag.meta.response.model` OR + `ag.data.parameters.model`. The curated `*_models.curated.json` `pricing` only feeds the model + PICKER tooltip (FE `connectionUtils.ts`), never the run cost. So "add pricing to the catalog" + does NOT fix a $0.00 run. A harness shows $0.00 when it records only `gen_ai.request.model` + (which maps to `ag.meta.request.model`, a field the cost calc does NOT read) and its ACP usage + carries no cost. Fix: emit `gen_ai.response.model` on the harness LLM span (Pi already does; + Codex did not). Lesson for the next harness: DIAGNOSE cost by querying the actual span + attributes (`ag.meta.response.model`, `ag.metrics.tokens/costs`) via `POST /tracing/spans/query`, + never by trusting a catalog-shaped hypothesis. litellm often already knows a new model id, so a + $0.00 is almost always a wrong/absent recorded model string, not missing pricing. Scope the + `gen_ai.response.model` stamp to the harness that needs it (litellm may know another harness's + model too and would silently recompute its cost). +- 2026-07-24 · **MCP tool names differ per harness: Claude `mcp____`, Codex + `mcp..` (dots).** Any name-matching on the EXECUTION path must handle both, or the + spec lookup misses: `bareToolName` (`client-tools.ts`, used for client-tool correlation AND the + ACP gate's spec resolution) and `serverPermissionFor` (`acp-interactions.ts`). Symptom of a miss: + the runner logs `[HITL] ... executor="harness"` with the full dotted anchor instead of + `executor="relay" specName=""`, and the tool's real permission is not read (it falls to + the plan default). Tool EXECUTION still works (the loopback MCP runs the call independent of the + gate), so this is invisible until you check the gate classification or exercise M3 gating. +- 2026-07-24 · **Agenta tools reach a non-Pi harness with NO per-harness runner change.** Delivery + is capability-gated: the runner stands up the internal `agenta-tools` loopback MCP server + (`buildToolMcpServers`) whenever the daemon-probed capabilities carry `mcpTools`. The Codex + daemon reports the full capability set (mcpTools/toolCalls/…), so callback/platform tools deliver + and execute (server-side relay) exactly like Claude.

This means M2 tool execution does NOT require wiring + `agent-full-access`; that (D-008's approved default, so no gate fires at all, and robustness when + the runner permission default is `ask`/`deny`) is intertwined with M3's runner-side gate + + per-agent mode override and was kept there. If you pull it forward, set the session mode via the + proven `session.setConfigOption("mode","agent-full-access")` (spike e-round) or `session.setMode`. +- 2026-07-24 · **Capturing a replay fixture off the streaming service path: merge the events in.** + The SDK stream's terminal `{kind:"result"}` record carries `events: []` — the tool_call / + tool_result / message events arrive as separate `{kind:"event"}` records and are folded live, not + batched into the terminal result. To capture a fixture the replay `result_from_wire` can parse + with populated `result.events`, accumulate the streamed events and write them into the recorded + result's `events` array (the one-shot `_deliver_result` shape). Redact `sessionId` / `traceId` / + tool-call ids; a result payload holds no secrets. Assert STRUCTURE (tool name, channel, capability + flags, stop reason), never the tool backend's success (ours recorded `isError` because the QA + deployment had no Composio provider) or prose. + +## Milestone 3 — permissions and human-in-the-loop + +- 2026-07-24 · **The runner-side tool gate at the loopback MCP seam resumes by COLD REPLAY, not + keep-alive.** The `tools/call` on the internal `agenta-tools` HTTP MCP server is a synchronous + request tied to the turn; when an `ask` tool parks, the socket is aborted (the `MCP_PAUSED` + sentinel) and the turn ends, exactly like the existing client-tool pause. There is NO ACP + permission id at this seam, so the Claude/Pi keep-alive `respondPermission` path does not apply. + Build the gate by mirroring `buildClientToolRelay`: `responder.onPermission` → allow executes, + deny returns an MCP tool error, ask emits a `user_approval` interaction + `onPause` + `MCP_PAUSED`. + On the follow-up turn the model re-issues the call and `ConversationDecisions` (built from the + `{approved}` envelope in history) consumes the decision. Reuse the existing machinery; do not + invent keep-alive here. Keep-alive live park stays for real ACP gates (authored `agent` mode). +- 2026-07-24 · **Set the Codex ACP session mode with `session.setConfigOption("mode", )`, + applied right after `applyModel` in acquire, best-effort.** This is the spike-proven channel; + `session.setMode(modeId)` is the ACP-standard sibling and also exists, `INITIAL_AGENT_MODE` is an + unverified daemon-env alternative (skip it). The default `agent-full-access` needs no wire field + (apply it for every Codex run); the per-agent OVERRIDE needs one — a dedicated typed + `harnessMode` field beats a generic blob (design-interfaces discipline). Never fail the run on a + mode-application error. +- 2026-07-24 · **The daemon SDK normalizes codex's per-gate option ids to `once/always/reject`.** + Codex exec gates offer `allow_once/allow_always/accept_execpolicy_amendment/reject_once` and MCP + gates offer `allow_once/allow_session/allow_always/decline`, but the daemon presents + `availableReplies: ["once","always","reject"]` and `respondPermission(id,"once"|"reject")` maps to + the right option (never the persistent "always"). So the shared `decisionToReply` needs no + codex-specific reply mapping. The codex-specific work is IDENTITY recovery: MCP permission frames + are nearly empty (`_meta.is_mcp_tool_approval`, no rawInput) so recover name+args from the recorded + `tool_call` event by `toolCallId`; exec frames key on `rawInput.command` like Claude's Bash. +- 2026-07-24 · **Enable the executable-tool gate only for a LOCAL non-Pi harness + (`!plan.isPi && !plan.isDaytona`) and make the deferred gate fail closed (deny) when unset.** The + Daytona in-sandbox stdio shim path is a separate delivery route; leave it untouched until a + dedicated Daytona milestone. Reuse the `deferred*Ref` pattern (like `deferredClientToolRelay`) so + the per-turn gate is swapped in via `currentTurn` without re-attaching session listeners. +- 2026-07-24 · **Rebuild the deployment FROM THE WORKTREE root.** `run.sh --env-file + .env.ee.dev.local` resolves the env relative to the cwd, and the main checkout's copy targets a + different `COMPOSE_PROJECT_NAME` than the worktree's.

His proposed design: keep the durable home (native +rollouts durable, native resume survives sandbox replacement; SQLite stays in-VM, +a hard filesystem constraint), and manage the credential by lifecycle: write +auth.json at session start, delete it from durable storage before the sandbox +stops. He also asked for deeper research on whether codex can take a key with no +credential file at all (the surprise that no file-free path exists). + +**Final ruling (Mahmoud, 2026-07-25): FILE-FREE managed auth on the durable home, +both local and Daytona.** The research (`spike/auth-and-cleanup-research.md`) +found codex 0.145 supports a custom model provider with `env_key`: the key is read +from the process environment AT REQUEST TIME, no credential file ever exists, the +built-in provider's hardcoded login requirement is bypassed by design, and the +WebSocket-upgrade caveat disappears (custom providers do not attempt it). Probed +green end to end on the daemon path against both a local listener (placeholder +byte-exact in the header) and the real API. This restores `CODEX_HOME = +/.codex` on the durable mount for Daytona (native resume durable, Mahmoud's +requirement), keeps `CODEX_SQLITE_HOME` in-VM (hard geesefs constraint), deletes +both managed auth.json writers and every cleanup backstop (including a discovered +ordering bug where the local backstop ran after the storage unmounted and stranded +the file), and composes exactly with the #5277 placeholder (which lands in the +same process environment `env_key` reads). Subscription mode is unchanged (the +operator's own login file via symlink). The add-then-remove lifecycle stays +documented in the research file as the fallback if a future codex version breaks +the provider mechanism. Process post-mortem for why this was missed for three +milestones: the enumerate-mechanism-space rule, recorded in the add-harness skill +and session memory. + +The rejected in-VM amendment text follows for the record: +The managed ruling approved `CODEX_HOME = /.codex` plus the requirement that on +Daytona the key be reliably deleted at session end. Milestone 5 implementation found +that requirement is not reliably satisfiable with the key on the durable cwd: on +Daytona the cwd is a geesefs mount of durable S3 storage, and the teardown path pauses +or destroys the sandbox (`environment.ts` destroy: sandbox pause/destroy runs before +any per-run file backstop), so a key written under the durable cwd can outlive the run +in the store, and a paused (parked) sandbox keeps it for reuse. The repair, same class +as the P8 SQLite amendment: for a managed Daytona codex run, put `CODEX_HOME` on an +IN-VM path (`/home/sandbox/agenta/codex-home/`, a sibling of the relay +and tool-MCP dirs) and `CODEX_SQLITE_HOME` on the matching in-VM path. auth.json then +lives only in the sandbox VM and is reaped with it — the strongest form of "reliably +deleted at session end" (the key never touches durable storage at all). An authored +`.codex/config.toml` still applies: `prepareWorkspace` writes it under the cwd and +codex reads it as the workspace config layer (D-007), independent of `CODEX_HOME`. +Trade-off recorded: this deviates from the literal `/.codex` managed layout for +Daytona only (local is unchanged), and codex's native `sessions/` rollout is in-VM, so +cross-sandbox-replacement native resume is not durable on Daytona — acceptable because +`harnessSessionMounts` has no codex mapping today (no codex durable session resume on +Daytona exists to lose), and warm-sandbox reconnect preserves the in-VM state within a +conversation. Subscription + Daytona stays rejected. Smallest-safe-version: the +credential is kept off durable storage; if Mahmoud prefers the literal cwd layout, the +alternative is a cwd home plus an early-in-destroy sandbox-API delete that fires only on +true teardown (not park) while the sandbox is still alive — more moving parts for weaker +safety. + +**Amendment (2026-07-25, security-forced):** the subscription home is now the +SYMLINK ASSEMBLY, not the whole-directory mount. Milestone 4's leakage check proved +the operator's own `config.toml` leaks into product sessions when the mounted +directory is the home: a personal `[mcp_servers.*]` entry spawned and was called +inside a run, and `CODEX_CONFIG` deep-merges additively, so it can add servers but +never remove the operator's (evidence: `spike/config-leakage-findings.md`). The fix +uses the P4-verified mechanism this register kept alive as fallback: the runner +owns a per-session `CODEX_HOME` (its own config, if any), and only `auth.json` is a +symlink into the operator's mount; refresh writes flow through in place, and the +store mode is pinned to `file` via a single-key `CODEX_CONFIG` (allowed: the +poison-combo constraint bans `sandbox_mode` there, not this key). The +operator-facing contract is unchanged (mount the codex directory, set the env var); +what a product session can see from that directory shrinks to the credential file. + +Original analysis (kept for the record): + +Codex reads everything from one directory: `$CODEX_HOME` holds `config.toml` (run +configuration we render), `auth.json` (the credential), and codex's own session state. +Claude separates login (mounted directory) from run config (a file in the session +working directory); Codex does not, so the layout is a real decision. + +**Managed-key mode (vault key):** + +- Option A (recommended): `CODEX_HOME = /.codex`. The SDK renders + `config.toml` as a harness file at `.codex/config.toml` (the existing blind-writer + seam, exactly like `.claude/settings.json`); the runner writes `auth.json` into the + same directory with the pi-assets discipline (0600, create-if-absent, + delete-only-if-created, and delete `auth.json` at session end). File-by-file: + `config.toml` from the SDK via harness files; `auth.json` from the runner; state + files written by codex, left to the session lifecycle. + Trade-offs: zero new wire machinery; the workspace-layer duplication is harmless + because the same file is both the primary and the workspace config. Cost: on + Daytona the cwd is durable storage, so the key file must be reliably deleted at + session end (the delete-only-if-created pattern covers it), and codex state files + persist in the session workspace (arguably a feature: codex memory follows the + session). +- Option B: `CODEX_HOME` = an ephemeral directory outside the cwd (the tool-MCP-dir + pattern). Cleaner separation, but `config.toml` can no longer ride the harness-file + seam (paths are cwd-relative and the writer is blind), so it needs either a new + wire field or runner-side knowledge of codex config, both of which break the + "adapter renders, runner writes blindly" division. + +**Subscription mode (local only, operator's ChatGPT login):** + +- Option A (recommended): the operator mounts their codex directory and sets + `CODEX_HOME` to it, mirroring `CLAUDE_CONFIG_DIR`; codex reads and refreshes + `auth.json` there directly (refresh keeps working; nothing is copied). Run + configuration is delivered via `CODEX_CONFIG` (the adapter's environment JSON, + proven to override file config in both directions) so the operator's own + `config.toml` in the mount does not leak into runs. One open verification: whether + the runner can scope that environment variable per run under daemon session + pooling. If it cannot, the fallback inside this option is workspace-layer files, + which can only tighten; the registered degradation is that per-tool pre-allow + (F-046) does not apply on subscription runs, so "allow" tools park like "ask" + tools. +- Option B: copy `auth.json` from the mount into a per-run home. Full config control, + but a token refresh during a run lands in the throwaway copy; if the backend + rotates refresh tokens, the operator's real login silently breaks.

Authors may override the mode per agent (`agent` mode with +its documented texture caveat). An upstream issue is filed asking codex-acp to +decouple approval policy from the full-access preset. Consequence for Milestone 3: +its scope shifts from codex-side settings rules to the runner-side tool gate; +`codex_settings.py` Layer 3 rendering remains only for authors who choose `agent` +mode. + +Context: codex-acp exposes three ACP session modes and sends their approval and +sandbox policies per turn, overriding whatever `config.toml` or `CODEX_CONFIG` say: +`read-only` (on-request approvals, read-only sandbox), `agent` (on-request approvals, +workspace-write sandbox; the default), and `agent-full-access` (approvals NEVER, +sandbox off). Additional verified facts: under `agent` mode, MCP tool gating and +per-server pre-allow work exactly as designed (F-046 intact); codex's own bubblewrap +sandbox fails to initialize in our containerized environments, which makes `agent` +mode approvals noisy and nondeterministic for shell commands (sometimes an approval +prompt phrased as "the sandbox failed, may I rerun?", sometimes the bwrap error +returned as the answer). And a poison combination exists: `sandbox_mode` next to +`approval_policy` inside `CODEX_CONFIG` silently disables all gates; the renderer +must never emit it (standing constraint, already communicated to implementation). + +Probe results (P6, P7 in `spike/derisk-findings.md`): + +- P6: under `agent-full-access`, NO codex-side configuration restores tool gates + (per-server prompt, per-tool prompt, and writes modes all ran gateless; the same + config gates correctly under `agent` mode). If we want tool approvals under full + access, the runner must enforce them itself: our `agenta-tools` MCP server can + pause a `tools/call` until a human answers, the same seam client tools already use. + That enforcement is our code, works for any harness, and needs no codex + cooperation. +- P7: codex's bundled sandbox CAN initialize inside our runner-image containers, but + only with `seccomp=unconfined`, `apparmor=unconfined`, and `SYS_ADMIN` plus + `NET_ADMIN` (or `--privileged`). That weakens the outer container boundary to + revive an inner one, and Daytona grants none of it. The root cause is Ubuntu + 24.04's restriction on unprivileged user namespaces, so even the bare host fails. + +Candidate postures with all facts in: + +- Posture 1: default `agent` mode. Approvals work everywhere (shell escalations, + Agenta tools, pre-allow), at the cost of noisy and nondeterministic shell texture + while the inner sandbox keeps failing: commands park behind "the sandbox failed, + may I rerun?" prompts, and sometimes the failure is returned as the answer instead + of asking. +- Posture 2 (recommended): default `agent-full-access` for shell, with Agenta-tool + approvals enforced runner-side at the `agenta-tools` pause seam (allow runs, ask + parks for the UI, deny refuses). Autonomous runs stay clean; tool-level + human-in-the-loop, the part the product actually promises, is preserved and owned + by our code. The gap versus Claude: no approval gate on raw shell commands; the + container or VM boundary is the enforcement there, which is the posture Mahmoud + already approved in the original D-004. Authors can still opt into `agent` mode + for gated shell. +- Posture 3: privileged local containers to fix the inner sandbox. Rejected as a + default: it trades real outer isolation for a nested sandbox, does not transfer to + Daytona, and turns the security boundary into host-configuration trivia. Possibly + a documented opt-in for self-hosters later. + +Follow-up worth filing either way: an upstream issue against codex-acp asking to +decouple approval policy from the full-access mode preset. + +**Amendment (2026-07-24, implementation constraint):** the runner-side ask gate +parks via the COLD-REPLAY pattern, not the keep-alive park. Reason: the +`agenta-tools` seam is a synchronous HTTP `tools/call` with no ACP permission id; +the connection cannot outlive a paused turn. This is the exact pattern client tools +(browser-fulfilled tools) already use in production: the turn pauses, the approval +surfaces in the UI, and on approval the next turn re-issues the call, which the +decision store then executes or refuses. Keep-alive parking still applies to real +ACP permission gates (the authored `agent` mode classification). Consequence: a +Codex ask-tool approval behaves like a client-tool approval, not like a Claude +ask-tool approval (which rides Claude's own ACP gate). Also fixed in the same +round: the mode override travels as a dedicated typed `harnessMode` wire field +(mirroring `model`), not a generic options blob. + +**Amendment (2026-07-25, bug-forced):** `codex_settings.py` must NOT render +`[mcp_servers.*]` tables for servers delivered over the ACP session channel. Codex +validates every config-file server entry for a transport and kills the session when +one is missing, which broke every tool run (root cause of the "deployment +regression" misdiagnosis; evidence in `reports/m3-implementation-notes.md`). Since +the runner-side gate is the permission authority under this ruling, the per-server +approval tables are dropped from the rendered config entirely. Consequence, +confined to the opt-in `agent` mode: pre-allow cannot be expressed to codex there, +so allow-tools pause at codex's own gate like ask-tools.

Model catalog: a curated entry (the live models are gpt-5.6-sol, the default, + gpt-5.6-terra, gpt-5.6-luna, gpt-5.5, and gpt-5.2; the gpt-5.1-codex ids still + appear in listings but the backend rejects them as deprecated). +4. Sidecar: Codex OAuth login already exists for the Pi path; the harness reuses it. +5. Release gate: a Codex cell. + +## Configuration: config.toml is the whole permission surface + +Codex reads its configuration from `$CODEX_HOME/config.toml`. The author-facing +permission options are `approval_policy` (untrusted, on-request, on-failure, never) +and `sandbox_mode` (read-only, workspace-write, danger-full-access). Per-MCP-server +and per-tool approval controls exist too: `default_tools_approval_mode` on a server +(auto, prompt, writes, approve) and a per-tool `approval_mode` override, plus +`enabled_tools` and `disabled_tools` lists. + +`codex_settings.py` mirrors `claude_settings.py` exactly in structure: + +- **Layer 1 (author options, pass-through).** The harness's `permissions` slice + carries codex-native keys (`approval_policy`, `sandbox_mode`) verbatim into + `config.toml`. We invent no vocabulary. +- **Layer 2 (sandbox boundary reinforcement).** Filesystem `readonly`/`off` maps to + `sandbox_mode = "read-only"` unless the author set something stricter. Network + restrictions map to disabling codex's web tools where config allows. +- **Layer 3 (per-server and per-tool rules).** Each user MCP server's permission maps + to that server's `default_tools_approval_mode` (allow → approve, ask → prompt, + deny → the server's tools go into `disabled_tools`). Each resolved executable + tool's permission maps to a per-tool `approval_mode` under the `agenta-tools` + server entry. The spike proved the critical case: a server set to `approve` runs + its tools with zero permission gates even under `approval_policy = "untrusted"`, + which is the Codex analog of the Claude per-tool allow rule (the F-046 requirement: + an "allow" tool must run without pausing). + +The rendered file rides the existing `harnessFiles` wire seam and the runner's blind +file writer, like Claude's `.claude/settings.json`. Where it lands is decision D-002. + +One Codex-specific hazard, registered as D-007: codex 0.145 also reads workspace +config layers (`/.codex/config.toml` and bare `/config.toml`). The spike +showed these can tighten gating but not loosen it. A user repo containing a stray +`config.toml` therefore silently influences codex behavior. + +## Credentials and the home directory (D-002, Checkpoint 1) + +Codex accepts three credential forms (all daemon-path proven): an `auth.json` +containing the API key (works with no environment variable at all), an environment +key plus the adapter's `DEFAULT_AUTH_REQUEST` auto-login, and an `auth.json` +containing ChatGPT OAuth tokens. The simplest managed-key setup is pre-seeding +`auth.json`; that is what the runner will do, with the same create-if-absent, +restrictive-mode, delete-only-if-created discipline `pi-assets.ts` uses today. + +The open layout question is where `CODEX_HOME` points in each mode; the options and +the recommendation are in D-002. The subscription mode additionally interacts with +per-run config delivery (the mount holds the operator's own `config.toml`), covered +in the same decision. The adapter offers one more delivery channel that may resolve +it cleanly: `CODEX_CONFIG`, a JSON object in the environment merged into every +session's config, proven able to loosen as well as tighten. Whether the runner can +scope that environment variable per run (given daemon session pooling) is marked TO +VERIFY early in Milestone 1. + +## Approvals and human-in-the-loop (D-003, D-004) + +The bridge raises real ACP `session/request_permission` frames on the same channel +Claude's do, so the park-and-resume architecture applies unchanged. The Codex branch +in `acp-interactions.ts` must handle three verified differences: + +1. Exec gates carry no tool name, only `kind: "execute"` plus the raw command; the + classification keys on that, like Claude's Bash gate. +2. MCP gates arrive with an almost empty `toolCall` (no arguments); identity and + arguments must be joined from the earlier `tool_call` event by `toolCallId`. The + frame carries the marker `_meta.is_mcp_tool_approval: true`. +3. Codex names MCP tools `mcp..` with dots, not Claude's + `mcp____`; the per-server permission matching needs a mapping. + +Option sets differ per gate type, and the daemon SDK maps a reply of "always" to the +session-scoped allow in both cases, never a persistent one. That matches how the +runner treats Claude approvals. + +Two defaults need a ruling: the platform default `approval_policy` when the author +sets nothing (D-003), and the default `sandbox_mode` inside our containers (D-004). +The spike found codex's own bubblewrap sandbox fails to initialize in containerized +environments, so codex effectively cannot self-sandbox inside our infrastructure; +the practical posture is the one Claude already takes (the Agenta sandbox is the +boundary), but the interplay of approval policies with a disabled inner sandbox +changes gate frequency and needs one probe in Milestone 3. + +## Adapter supply chain (D-005) + +The daemon installs the Codex ACP bridge (`@agentclientprotocol/codex-acp`, which +bundles the codex CLI) from the ACP registry at first use with a floating version +range. The Claude bridge is pinned; the Codex one is not, and version drift there +changes protocol behavior under us. D-005 proposes pinning by pre-installing the +adapter at a fixed version (runner bootstrap in development, baked images for +production). + +## What is intentionally not designed + +- No E2B path (no E2B sandbox exists on main). +- No change to Pi's Codex-models path. +- No handling of codex's cross-session memory features: a per-run `CODEX_HOME` means + codex's own memory resets each run. If we ever want persistent codex memory, that + is a separate design on top of session mounts. +- Daytona subscription auth stays rejected, same rule as Claude. diff --git a/docs/design/codex-harness/lane-split-plan.md b/docs/design/codex-harness/lane-split-plan.md new file mode 100644 index 0000000000..84be7ac5e8 --- /dev/null +++ b/docs/design/codex-harness/lane-split-plan.md @@ -0,0 +1,167 @@ +# Lane-split plan + +> SUPERSEDED by decision D-009 (Mahmoud, 2026-07-25): the branch ships as a SINGLE PR with thorough +> inline review comments, NOT stacked lanes.

Tool calls appear as normal tool-call events with full input and +output. Crucially, setting a server's `default_tools_approval_mode = "approve"` ran +the tool with zero pauses even under the strictest approval policy, which is the +Codex equivalent of Claude's per-tool allow rules; per-tool overrides and +enable/disable lists exist too. Milestone 3's permission mapping therefore has a +complete target vocabulary. + +**All auth forms work.** A pre-seeded `auth.json` with the API key is the simplest +managed setup (no environment key needed). An environment key alone fails unless the +adapter's auto-login variable is set; worth knowing, easy to handle. A copy of your +ChatGPT OAuth `auth.json` authenticated through the daemon path; your live `~/.codex` +was never opened for writing, and no token refresh occurred during the test, so +refresh-against-a-copy remains the one untested corner (it shapes D-002's +subscription option). + +## Surprises worth your attention + +1. The Codex ACP bridge is installed unpinned from a registry CDN at first use, with + a floating version range; the Claude bridge is pinned. Its version defines the + frame shapes we classify. D-005 proposes pinning it. +2. Codex's own OS sandbox cannot initialize inside containers, so inside our + infrastructure codex cannot self-sandbox; the Agenta sandbox is the real boundary, + same as with Claude. D-004 proposes the matching default. +3. The current model generation is gpt-5.6 (sol default, luna cheapest); the + gpt-5.1-codex family still appears in listings but is rejected by the backend, and + the daemon's embedded default model is from a deprecated family, so we always pass + the model explicitly. + +## Checkpoint 1: the four rulings + +Full context and trade-offs in `decisions.md`; recommendations in one line each: + +- **D-002, CODEX_HOME layout.** Managed mode: put it at `/.codex` so the config + file rides the existing blind-writer seam and the runner only adds the credential + file (recommended).

Implementation written by Codex +(gpt-5.6-sol), orchestrated and reviewed by Opus. This file is the working record for the +milestone report. + +## Headline + +Milestone 1 is complete and green. Managed-key Codex streams a text answer end to end on +BOTH the ephemeral and the durable session-mount (playground) paths, including a multi-turn +run where a codeword set in turn 1 is recalled in turn 2. The durable-mount blocker found in +the first QA pass (Codex SQLite state wedging on the geesefs mount) is fixed with the approved +D-002 P8 amendment: keep `CODEX_HOME = /.codex` and add `CODEX_SQLITE_HOME` pointing at a +local off-mount directory (codex's supported upstream knob). Both unit suites green +(SDK agents 680, runner 1218). Quality passes done. Full evidence below. + +### Resolution of the durable-mount blocker (D-002 P8 amendment) + +The first QA pass hung on durable sessions because codex writes WAL-mode SQLite state into +`CODEX_HOME`, and geesefs (S3 FUSE) cannot support it. P8 (`spike/derisk-findings.md`) proved +codex exposes `CODEX_SQLITE_HOME` (upstream `codex-rs/state/src/lib.rs:93`), which moves all four +SQLite families (state/goals/logs/memories, each with `-wal`/`-shm`) off `CODEX_HOME` while native +`session/load` resume rides the plain `sessions/` rollout jsonl that stays on the durable home. The +fix (runner `codex-assets.ts` `configureCodexHome`): keep `CODEX_HOME = /.codex`, and set +`CODEX_SQLITE_HOME = /agenta/codex-sqlite/` (a local off-mount dir created +before the daemon starts, cleaned best-effort on destroy). The path is derived from `basename(cwd)` +(per-session-stable, like `relayDir`) so it does not enter the config fingerprint and warm daemon +reuse is preserved. This is parity-or-better with Claude (P8c: Claude keeps its SQLite-free state +off the geesefs cwd too). + +## Scope recap + +`HarnessType.CODEX`, the `CodexHarness` adapter + `CodexAgentTemplate`, `codex_settings.py` +(renders `.codex/config.toml`), capabilities + curated model catalog, golden wire fixture, +runner wiring (CODEX_HOME + managed `auth.json`, codex subscription rejection, daemon +config-dir inheritance), and tests both sides. Managed key only. No tools, no permissions UI, +no subscription, no Daytona. + +## Mid-flight correction (from derisk probe P2, applied during the slice) + +The coordinator relayed three changes after the SDK core landed, all now reflected: + +1. **No baked D-004/D-003 defaults in `codex_settings.py`.** P2 (`spike/derisk-findings.md`) + proved `codex-acp` sends `approvalPolicy`/`sandboxPolicy` per turn from its ACP `mode` preset, + overriding any config-file `sandbox_mode`, so baking `danger-full-access` / `on-request` there + is a no-op or misleading. `codex_settings.py` now renders ONLY authored options and emits no + file when nothing is authored (same rule as `claude_settings.py`). Platform defaults are + decision D-008 (pending), landing in Milestone 3. A text-only M1 run authors nothing (the + permissions schema does not carry codex keys yet), so it renders no `config.toml` at all and + runs under the adapter's default mode. This revision to the Codex-written `codex_settings.py` + and the `dtos.py` docstring was applied by Opus (a targeted correction, not fresh feature work). +2. **Never emit `sandbox_mode` inside a `CODEX_CONFIG` env JSON.** M1 uses no `CODEX_CONFIG` at + all; the poison-combo invariant is recorded as a standing comment in `codex-assets.ts`. +3. **Model still passed explicitly per run** (unchanged; rides the wire `model` field, applied by + the runner on the session like Claude). + +## Key implementation decisions made during the slice (not requiring a Mahmoud ruling) + +- **auth.json is written in the post-mount workspace step, not `environment-setup.ts`.** The task + brief placed the managed `auth.json` write beside `prepareLocalPiAssets` in + `environment-setup.ts`. That runs BEFORE the local durable geesefs mount is applied over + `plan.cwd` (the mount happens in `acquireEnvironment` before `prepareWorkspace`). Writing + `/.codex/auth.json` pre-mount would be shadowed by the mount on any session run. So + `auth.json` is written by `writeCodexManagedAuthFile` right after `prepareWorkspace` (post-mount), + and its created path is deleted by a `destroy` backstop mirroring `otlpAuthFilePath`. `CODEX_HOME` + (a path string, safe pre-mount) is still set in `environment-setup.ts` via `configureCodexHome` so + the daemon env carries it. This is an implementation-site choice forced by mount ordering, fully + within the approved D-002 layout. (Note: the same mount is what the blocker below is about.) +- **No `codex` provider group in `PROVIDER_ENV_VAR_GROUPS`.** `CODEX_HOME` is a config-dir PATH, + not a provider credential, so it belongs in the config-dir inheritance block of `buildDaemonEnv` + beside `CLAUDE_CONFIG_DIR` / `PI_CODING_AGENT_DIR` (research.md 3.5), not a provider group.

This is what the D-002 P8 amendment fixed. + +- **Durable session run, MULTI-TURN, after the fix — PASS.** Same product endpoint, harness `codex`, + model `gpt-5.6-luna`, with a fixed `session_id` and the conversation history replayed each turn + (the playground shape). Turn 1: "Remember this codeword: FLAMINGO-42. Reply with exactly: OK" -> + frames `start -> ... -> text-delta -> ... -> finish` (`finish reason: stop`), text `OK`. Turn 2 + (same session): "What was the codeword I gave you?" -> `finish reason: stop`, text + **`FLAMINGO-42`** (codeword survived turn to turn). No hang either turn. + + On-disk confirmation of the redirect (inside the runner container): + - `.codex/` on the geesefs mount held ONLY geesefs-safe files: `auth.json`, `installation_id`, + `sessions/` (the rollout jsonl), `shell_snapshots/`, `skills/`, `.tmp/`. NO `*.sqlite` files. + - `CODEX_SQLITE_HOME` (off-mount, `/agenta/codex-sqlite/`) held all the SQLite + families: `goals_1.sqlite`/`-wal`/`-shm`, `logs_2.sqlite`/`-wal`/`-shm`, `memories_1.sqlite`. + Exactly the split P8a predicted. + +### The `.tmp` / geesefs residual-risk observation (both directions) + +The coordinator flagged two residual risks on the real mount; both were checked and neither wedges: +- **`sessions/` rollout appends on geesefs: fine.** The rollout jsonl was written on the mount and + turn 2's native context worked (codeword recalled). +- **`.tmp/plugins-*` git clone on geesefs: benign, non-fatal.** Codex clones a plugins repo under + `CODEX_HOME/.tmp/plugins` at session start. Git DOES trigger `geesefs: *fuseops.CreateLinkOp error: + function not implemented` (git uses hardlinks), but it is non-fatal: git degrades, the + `.tmp/plugins` dir plus `plugins.sha`/`plugins.sync.lock` were created, and both turns completed + cleanly. So the geesefs-lethal case was ONLY the SQLite WAL (now redirected off-mount); the git + hardlink attempts in `.tmp` fail harmlessly. No design response needed. (Separately, some + `InvalidAccessKeyId` 403s appeared in the log window, but they belong to the ORPHANED mount of the + earlier pre-fix hung session, whose temporary S3 credentials had expired, not to the fixed path.) + +## Quality passes (milestone close) + +- **`/simplify` (single-pass inline; the Agent fan-out was unavailable in this context).** Reviewed + the milestone diff for reuse, simplification, efficiency, and altitude. Findings: the + Claude/Codex identical `wire_tools` is real duplication but collapsing it into the base would + touch Claude and break the deliberate mirror (skipped, out of scope); the `codex_settings` + renderer and the `INTERNAL_TOOL_MCP_SERVER` constant are unused in M1 but are explicitly-requested, + clearly-labeled forward-structure for Milestone 3 Layer 3, and keeping the constant preserves + parity with `claude_settings.py` (kept). No code changes; the code was already clean. +- **Desloppify.** The `.agents/skills/desloppify-*` directories are present but EMPTY in this + worktree (no `SKILL.md` or engine content materialized), so the skills could not be invoked as + written. I applied the desloppify principles manually, scoped to the touched files: no + narration/session-dialogue comments, no dead scaffolding beyond the noted intentional + forward-structure, comment density matches the surrounding `pi-assets`/`claude_settings` norm + (why/invariants only), naming consistent. No changes needed. +- **Final fresh-eyes diff review** (`git diff 7b971d8c10..HEAD`): correctness re-confirmed by the + green suites; style parity with the adjacent Claude code holds; no debug artifacts, no `TODO`/ + `FIXME`, no em-dashes in prose. Clean. +- **Suites re-run after the passes:** SDK agents unit **680 passed**; runner full **1218 passed**. + +## Open questions (none blocking) + +The durable-mount blocker is resolved (see the headline and the D-002 P8 amendment). No open +questions block Milestone 1. Informational notes carried forward: +- The runner's `codex-acp` bridge was already installed in the container from an earlier session, + so first-run install latency was not observed here. D-005 pinning still applies for a clean image. +- The `.tmp/plugins` git clone triggers benign `CreateLinkOp` warnings on geesefs (git degrades, + no wedge). If a future codex version makes that git activity fatal, it has no upstream override + knob today and would need a design response (noted, not currently a problem). + +## Deferred + +- **Daytona managed Codex** (auth.json write into the remote sandbox, delete-only-if-created there): + Milestone 5. `writeCodexManagedAuthFile` no-ops for `isDaytona` today. +- **Codex subscription (`runtime_provided`, CODEX_HOME mount):** Milestone 4.

Judgment context +applied per the pass brief: Claude-harness style parity is a goal (not slop), comments state +invariants only, forward-structure reserved for Milestone 3 is intentional, and cross-harness +generalization (e.g. deduplicating Claude/Codex `wire_tools`) is out of scope. + +### Scan and review findings + +The milestone code scans clean. Mechanical scan across the new production files found zero +slop signals: no `TODO`/`FIXME`, no debug `console.log`/`print`, no `any`/`as any`/`@ts-ignore`, +no bare `except`/`noqa`, no empty catches, no swallowed errors, no hardcoded secrets, no +copy-paste marker comments. Every new symbol is wired and reachable (`CodexHarness` in the +harness registry; `CodexAgentTemplate.wire_harness_files` -> `build_codex_settings_files`; the +codex model-catalog loaders via `model_catalog_entries`; `configureCodexHome` / +`writeCodexManagedAuthFile` from the environment setup/acquire path; `CODEX_SUBSCRIPTION_UNSUPPORTED_MESSAGE` +from `buildRunPlan`) — no dead exports. Data consistency holds: `data/codex_models.curated.json` +ids match `CODEX_MODELS` in `capabilities.py` exactly, and the golden `run_request.codex.json` +is asserted on both wire sides. New tests are genuine (real assertions, no skips/xfail, +tautologies, or placeholder bodies).

Since style parity + with the Claude adapter is an explicit goal and Claude is the reference, aligned it: imported + `PermissionMode` from `..tools.models` (the same top-level import `claude_settings.py` already + uses) and changed the annotation.

No behavior change. + +### Consciously skipped + +- **Reserved Milestone 3 forward-structure** — `build_codex_settings_files`'s unused + `sandbox_permission` / `mcp_servers` / `tool_specs` / `permission_default` parameters, the + `INTERNAL_TOOL_MCP_SERVER` constant, and the Layer-2/Layer-3 hooks in `codex_settings.py`. + Explicitly reserved and documented for the permissions milestone; kept per the brief. +- **Claude/Codex parity duplication** — near-identical `wire_tools`, the `custom_tools` property, + and the `CodexHarness`/`ClaudeHarness` bodies. Intentional mirror; deduplicating across + harnesses is out of scope. +- **Prettier-reformatted unrelated import blocks** in `environment.ts`, `environment-setup.ts`, + and `runtime-contracts.ts` (multi-line imports collapsed).

Root cause: Codex keeps internal state as +SQLite databases inside its home directory, and durable sessions put that home on +the S3-backed mount, which cannot support SQLite's write-ahead mode. The fix came +from probing rather than guessing: Codex has a supported switch +(`CODEX_SQLITE_HOME`) that relocates exactly the SQLite files, and a resume +experiment proved session continuity rides plain transcript files that are safe on +the mount (the same class of writes Claude's transcripts already do there). So the +approved layout stayed, one environment variable moved the state to local disk, and +the re-run passed: two turns on a real durable session, the codeword recalled, no +sqlite files on the mount. The residual worry (Codex runs a git operation in a +scratch folder on the mount) proved benign: git logs a warning about hard links and +degrades gracefully.

In a live run on the worktree deployment, +Codex called the platform's `discover_tools` tool; the runner's internal +`agenta-tools` MCP server delivered it, executed the call server-side through the +relay, and both the tool call and its result appear in the trace. Two facts made +this milestone smaller than planned, which is the good kind of surprise: tool +delivery needed no Codex-specific runner change at all (the channel is gated on a +capability the Codex daemon already reports), and the only real gap was naming. +Codex addresses MCP tools as `mcp.server.tool` with dots where Claude uses +underscores, so the two name-parsing helpers on the execution path now understand +both forms. That one fix moved tool execution from "the harness tries to run it +itself and misses" to "the runner relays it with the tool's real permission +attached." + +Run cost now renders correctly (a real turn showed $0.0116 on 11.5K tokens instead +of $0.00). + +## A wrong diagnosis from Milestone 1, corrected honestly + +Milestone 1 blamed the $0.00 cost on missing catalog pricing.

No `CODEX_CONFIG` is composed anywhere in M1-M3 (`codex-assets.ts` +carries the standing-invariant comment). The mode is set via the ACP `setConfigOption` channel, +which never touches `sandbox_mode`, so the poison combo (`sandbox_mode` next to `approval_policy` +inside `CODEX_CONFIG`) cannot arise. When M4 introduces `CODEX_CONFIG` for the subscription path, +the guard must live there. + +## Resume semantics (surfaced, approved) + +The runner-side MCP-seam gate (B) cannot use the ACP keep-alive resume that Claude/Pi use: there is +no ACP permission id at the loopback seam, and the `tools/call` HTTP request dies when the turn +parks (the socket is aborted, exactly like the existing client-tool pause). So its resume is COLD +REPLAY: the model re-issues the call on the follow-up turn and `ApprovalResponder.onPermission` + +`ConversationDecisions` consume the `{approved}` envelope from history to execute or refuse. The +coordinator approved this as the existing client-tool pause pattern (an approved copy of a +production mechanism). UX note for users: a Codex ask-tool approval behaves like a client-tool +approval (the turn pauses; you approve; the next turn completes the call), not like Claude's live +in-turn park. Claude's keep-alive live park remains for real ACP gates under authored `agent` mode +(slice C). + +## Live QA — PASSED at the wire level (after the Slice D fix + a resume-key fix) + +Root cause of the earlier "blocker" was NOT a deployment regression (my control was invalid — the +SDK, which renders config.toml, is bind-mounted into the SERVICES container, so reverting the +runner never reverted Slice D). It was Slice D rendering transport-less `[mcp_servers.*]` tables, +which codex 0.145 rejects at `session/new`. Fixed (see the D-008 amendment + the earlier evidence +below). A second bug then surfaced live: the runner-side ask gate keyed the stored decision on +codex's MCP-wrapped args `{server,tool,arguments}` while the gate keyed on the bare `{}`, so an +approval re-parked instead of resuming — fixed by unwrapping the wrapper symmetrically in +`storedDecisionKeyShape` (`permission-plan.ts`, committed `0c925cb3`). + +QA driver: `spike/scripts/m3-qa.py` (self-contained `list_connections` platform tool, no Composio). +All scenarios verified on the worktree deployment (:8180, project 019f93b7…), harness codex, default +`agent-full-access`: + +- **Scenario 1 (allow)** — PASS. The tool ran with no pause: `tool-input-available` → + `tool-output-available` ("No connections found"), `finish=stop`, no approval frame. +- **Scenario 3 (deny)** — PASS. `tool-output-error`, the model replied "I couldn't list connections + because the tool was denied by policy", the turn continued to `finish=stop`. +- **Scenario 2 (ask) park** — PASS. `tool-approval-request` surfaced, `finish=other` + ("Conversation interrupted"), the codeword FLAMINGO-42 was acknowledged, no tool output. +- **Scenario 2 warm approve-resume (2a)** — PASS. The follow-up turn cold-replayed + (`create_session mode=create`), consumed the normalized decision `list_connections#{}`, executed + the tool, and the reply carried "Codeword: FLAMINGO-42" (context survived). +- **Scenario 2 reject-resume** — PASS. "The tool call was rejected and not executed", no execution. +- **Cold resume (2b) context check** — PASS via the natural cold-replay: the MCP-seam pause tears + the session down, so EVERY resume is a cold `create_session mode=create` on the owning replica + (proven in the runner logs alongside the normalized decision + tool execution + codeword). The + additional runner-KILL variant is inapplicable to LOCAL sandboxes by design: a killed runner gets + a new replica id and the single-owner guard correctly refuses to move a local session + (`local sandbox requires a single runner ... Refusing to cold-start on the wrong host`). A + cross-replica cold resume is a Daytona concern (M5), not a local-M3 one. So the cold-resume + CONTEXT check succeeds; there is nothing to STOP-and-report. +- **Agent-mode wire sanity** — PASS. With authored `mode=agent` the runner logs + `[codex-mode] applied mode=agent`, then a Codex ACP gate classifies (Slice C recovers + `anchor=list_connections` from the `kind:"execute"` MCP frame, `argKeys=undefined`) and parks + (`permission=ask outcome=pendingApproval`), surfacing a `tool-approval-request`. + +Outstanding: the chrome-devtools MP4 (`m3-approvals-qa.mp4`) is not yet recorded (budget). The +wire-level SSE evidence above fully validates the behavior; the UI recording is the watchable +proof and remains the one open QA deliverable. The driver is ready to drive it. + +Multi-session note: the M4 orchestrator is concurrently active on this stack and restarted the +runner mid-QA more than once (each restart errored an in-flight resume). QA batches were re-run in +stable windows. A concurrent git operation also reverted this session's uncommitted resume-key fix +once; it is now committed (`0c925cb3`), so a runner restart reloads it correctly. + +## Live QA blocker (historical — root cause corrected above) + +The three recorded scenarios (allow/ask/deny) + the coordinator's warm/cold codeword resume + the +MP4 could NOT be produced. Every Codex run that includes an MCP server (the internal `agenta-tools` +channel, which every tool run needs) fails with `Agent run failed: Internal agent error: Internal +error` — the codex daemon (surfaced via `acp-http-client`) errors at session/prompt time, BEFORE +any tool_call, right after the internal MCP server starts. Baseline codex chat (no tools) works. + +Proven independent of this milestone's code: + +1. Disabling slice A (mode) → still fails. +2. Disabling slice B (executable gate) → still fails. +3. Loading the exact M2 runner code (commit `378d527`, whose notes document this same tool QA + PASSING earlier today) → fails identically. +4. A full `run.sh --rebuild runner --build` → does not fix it. +5. codex-acp pinned at 1.1.7 (no version drift); baseline chat proves the codex binary + adapter + are functional. + +So the codex tool path is broken at the deployment level (the codex daemon cannot use the internal +loopback HTTP MCP server in the current container state — likely a networking/daemon-environment +regression from today's container recreate/rebuild churn). This is a deployment issue for +investigation, not a defect in the M3 code. The QA driver +(`spike/scripts/m3-qa.py`, self-contained `list_connections` tool, allow/deny/ask + cold-resume +codeword scaffolding) is ready to run the moment the deployment serves codex tool sessions again. + +## Deployment note (own goal, corrected) + +The rebuild command must run FROM THE WORKTREE root: `.env.ee.dev.local` in the main checkout +targets a different compose project (`agenta-ee-dev-wp-b2-rendering`), while the worktree's +`.env.ee.dev.local` carries `COMPOSE_PROJECT_NAME=agenta-ee-dev-codex-harness` (the QA deployment at +:8180).

(context survived the pause/approve/deny cycle). +7. **DENY run** — policy `Deny all`: the tool call is refused (`failed`, "denied by policy") and the + agent continues to a clean final answer ("it was denied by policy, so I couldn't verify the + result"). + +Key finding surfaced during recording (folded into LESSONS.md): the M3 runner-side gate is driven +in the product UI by the **agent-level `Permissions` policy** (`Allow reads` / `Allow all` / `Ask` / +`Deny all` under Advanced), which maps to the gate's allow/ask/deny decisions and fires for +**runner-executed** tools (platform ops, workflow references, MCP). A "schema-only / executed by +your app" custom tool is a CLIENT tool that bypasses the runner gate entirely (returns +`{"status":"not_handled"}`, "not handled by this client"), so it cannot exercise or demonstrate the +gate. Under `Ask`, each call parks with an Approve/Deny card; approving executes and the model may +re-issue the call (it re-parks every call under `Ask` — expected, not a bug); denying yields a clean +final answer.

The warm and cold resume variants you asked about +were both verified at the wire level with the codeword check; on the local sandbox +every approval resume is the cold-replay path by construction, and context +survived it. + +## What was built + +Per the D-008 ruling: Codex sessions default to full access inside the sandbox +boundary, and tool approvals are enforced by our own runner at the point where a +tool call arrives, allow executes, ask pauses for the UI, deny refuses. Authors can +opt a Codex agent into the gated mode through a typed option, and for that mode the +runner classifies Codex's native approval requests (with their quirks: nameless +exec frames, argument-less MCP frames joined by call id, dot-separated tool names) +into the same parked-approval machinery Claude uses. + +## Live QA earned its keep: two real bugs found, fixed, and regression-tested + +1. The settings renderer emitted approval-only MCP server entries into Codex's + config file; Codex validates every such entry for a transport and killed every + tool session at creation with a generic internal error. This was briefly + misdiagnosed as a deployment regression because a rollback control only reverted + the runner while the code lives in the SDK, which mounts into a different + container; a debugging agent corrected the diagnosis with a single-variable + proof. The fix drops those entries entirely, since our runner-side gate is the + permission authority, and a regression test pins the rendered config shape. Cost + of the accepted trade-off: in the opt-in gated mode, pre-allowed tools pause at + Codex's own gate rather than running silently. +2. An approval that was granted re-parked instead of resuming: the stored decision + and the gate keyed the tool arguments in two different shapes. Unit tests could + not see it because both sides were consistent within each test; only a live + park-and-resume cycle exposed it. Fixed with a symmetric key normalization plus + a unit test that now encodes the asymmetry. + +Both incidents produced playbook lessons (validate rendered harness config against +the harness's own validator; a rollback control must cover every container that +ships the suspect code). + +## One product boundary made explicit + +The runner-side gate governs runner-executed tools (platform operations, workflow +references, MCP tools). Schema-only tools that your application executes are client +tools and take the client pause path instead; they never reach this gate.

Daytona managed-key path + +### What shipped (`services/runner/src/engines/sandbox_agent/`) + +- `codex-assets.ts`: `codexDaytonaHomeDir` / `codexDaytonaSqliteHomeDir` (in-VM paths under + `/home/sandbox/agenta/`, siblings of the relay and tool-MCP dirs, off the geesefs cwd); + `configureDaytonaCodexEnv(plan, daytonaEnv)` sets `CODEX_HOME` + `CODEX_SQLITE_HOME` for a managed + Daytona codex run; `writeCodexDaytonaManagedAuthFile(sandbox, plan, log)` writes `auth.json` into + the in-VM home through the sandbox FS API after the sandbox starts. +- `environment-setup.ts`: calls `configureDaytonaCodexEnv(plan, piExtEnv)` so the paths reach the + Daytona daemon env (fixed at sandbox creation, built from `piExtEnv`). +- `environment.ts`: calls `writeCodexDaytonaManagedAuthFile` inside the `isDaytona` prep block. +- Tests: 4 new cases in `sandbox-agent-codex-assets.test.ts` (env set for managed Daytona; no-op for + local/subscription/non-codex; auth write via a fake sandbox; no-op without a key). + +### The design decision (D-002 M5 amendment, proposed — awaiting ratification) + +The approved managed layout is `CODEX_HOME = /.codex` plus "reliably delete the key at session +end." On Daytona the cwd is a geesefs mount of durable S3, and the teardown path pauses or destroys +the sandbox *before* any per-run file backstop could delete a key written under the cwd, so that +requirement is not reliably satisfiable there. The repair (same class as the P8 SQLite amendment): +put `CODEX_HOME` on an **in-VM** path for a managed Daytona run, so `auth.json` lives only in the +sandbox VM and is reaped with it. The key never reaches durable storage. Trade-offs recorded in +`decisions.md`: this deviates from the literal cwd layout for Daytona only (local unchanged), and +codex's native `sessions/` rollout is in-VM, so cross-sandbox-replacement resume is not durable on +Daytona. That loses nothing today because `harnessSessionMounts` has no codex mapping (no codex +durable session resume on Daytona exists yet), and warm-sandbox reconnect preserves the in-VM state +within a conversation. An authored `.codex/config.toml` still applies via the D-007 workspace layer. + +### Daytona-Secrets (#5277) compatibility + +`writeCodexDaytonaManagedAuthFile` carries an explicit invariant comment: the key string is written +**opaquely**. Under the placeholder design the runner would receive a placeholder here, not the real +key, and Daytona's egress proxy substitutes it in flight. P3 proved codex copies the credential +byte-exact into request headers with no client-side validation, so the writer never inspects, +parses, or reformats the string. Same note is in the harness-adapters doc. + +### Live QA (direct runner `/run`, bypassing the product connection resolver) + +The product path (`/services/agent/v0/invoke`) is blocked in this deployment by a **managed +connection resolver failure** that is harness-independent: an explicit-slug managed connection +(`{mode: agenta, slug: "openai-managed"}`) returns "connection 'openai-managed' not found for +provider 'openai'" for local codex AND is the same for any harness. The release-gate probe (which +uses the default slug-None managed path) works, so the failure is specific to the explicit-slug +lookup and predates this milestone (M4 used subscription, not managed). Debugging the EE resolver is +out of scope. + +The runner code was therefore verified at the authoritative layer, the runner `/run` endpoint with +the key in `secrets` and `credentialMode=env` (the sidecar-trust pattern), which is exactly the code +M5 added: + +- Model `gpt-5.6-luna` was **rejected by the Daytona sandbox's codex** with + `Allowed values: gpt-5.3-codex, gpt-5.4, gpt-5.2-codex, gpt-5.1-codex-max, gpt-5.2, + gpt-5.1-codex-mini`. The Daytona snapshot `agenta-agent-sandbox-v1` ships an **older Codex** than + the runner-pinned 1.1.7 (whose local model set is the gpt-5.6-* family). See "Daytona snapshot pin" + below. +- With `gpt-5.4` the run was fully green: `{"ok":true,"output":"DAYTONA-OK", stopReason:"end_turn", + model:"gpt-5.4"}`, the in-VM `auth.json` authenticated the session, and the sandbox parked cleanly. + +Tool run on Daytona: a real product-path tool run is blocked by the same managed connection resolver +issue (platform-tool execution needs the product context, not a raw `/run`). The Daytona non-Pi tool +CODE path (`uploadToolMcpAssets` shim upload plus the in-VM auth) is in place and unit-covered, and +the chat run proves auth + session on Daytona; per the milestone brief this sub-thread is documented +and STOPPED rather than hacked around the resolver. + +### Deployment wiring for QA + +The worktree `.env.ee.dev.local` gained the `AGENTA_RUNNER_DAYTONA_*` values (copied from the main +checkout) and `AGENTA_RUNNER_ENABLED_SANDBOX_PROVIDERS=local,daytona`. The runner, services, and api +containers of this project were recreated with `run.sh --recreate` to pick them up (the services and +api layers also gate the provider list). `docs/design/codex-harness/spike/scripts/m5-daytona-qa.py` +drives the product path (kept for when the resolver is fixed; `SANDBOX=local` isolates). + +## Daytona snapshot pin (finding, follow-up out of scope) + +The runner-image pin (D-005, item C) covers the RUNNER image only. The Daytona **snapshot** is a +separate image built elsewhere, and it ships its own, older Codex (the gpt-5.4-era model set). So a +managed Daytona codex run is pinned on the runner side but floats on the sandbox side. The follow-up +is to apply the same `install-agent codex --agent-process-version 1.1.7` pin to the Daytona snapshot +build. Filed as a note here; the snapshot recipe is not in this repo. + +## C. Adapter pin (D-005) + +The sandbox-agent daemon installs `@agentclientprotocol/codex-acp` into +`$HOME/.local/share/sandbox-agent/bin/agent_processes/codex/` at first codex use with a floating +`^1.1.7`. The daemon exposes `install-agent codex --agent-process-version `, which resolves the +tree and writes a `package-lock.json` (lockfileVersion 3) pinning codex-acp 1.1.7 exactly with its +integrity hash and bundled `@openai/codex` 0.145.0. Baking that install into the image at build time +means the daemon finds the adapter present at runtime and skips the floating fetch. Codex (codex-acp ++ codex CLI, both Apache-2.0) is licensing-clean to bake, unlike proprietary Claude Code. Verified +empirically in a throwaway `XDG_DATA_HOME` (the pinned install produced codex-acp 1.1.7 + codex +0.145.0). `Dockerfile.gh` pins `HOME=/home/node` so the build-time and runtime install dirs match; +an arbitrary runtime uid would miss the baked pin (documented caveat, same class as the existing +"non-root host uid" note). A full runner-image rebuild is the final confirmation; it belongs in the +runner lane's CI. + +## B. Release-gate cell + +Cell `X1` (`codex` / `local` / `gpt-5.6-luna` / managed) mirrors C3 (Pi local managed). Four +journeys PASS: `chat`, `tool` (a builtin-shell tool ran and the reply carried a shell-only token), +`commit` (a new revision round-tripped, v0→v1), `warm` (turns 2/3 faster). Four SKIP with reasons +now recorded in `coverage.md` and the journey code: + +- `mcp` SKIPs (user MCP is Claude-only). +- `approve` / `deny` SKIP because the gate's approval probe is a **builtin `bash`** command, which + codex runs gateless under its default `agent-full-access` mode (D-008); codex tool approvals ride + the runner-side `agenta-tools` pause seam (a client-tool-shaped park), verified in M3, not a + codex-native `tool-approval-request` frame. +- `mount` SKIPs because its token is extracted from a builtin-shell `tool-output-available` payload; + codex runs shell through native ACP exec frames with a different output shape, so the probe cannot + read the token even when the file persisted (the `tool` journey confirms codex shell runs). A + codex-shaped mount probe is a follow-up. + +## D. Documentation + +- `docs/docs/self-host/agents/01-use-your-own-subscription.mdx`: added the native Codex harness login + (`~/.codex/auth.json`, `codex login`) and its `CODEX_HOME` runner mount block, mirroring the Claude + and Pi rows, and clarified it against the existing "codex models through the Pi harness" path. + `codex login` and the auth path verified against the local codex CLI 0.145.0. +- `docs/design/agent-workflows/documentation/ground-truth.md` and the `interfaces/in-service/**` + inventory (`backend-adapter.md`, `harness-adapters.md`, `neutral-runtime-dtos.md`, `README.md`): + the harness enumerations now include `codex` / `CodexHarness` / `CodexAgentTemplate`, with a codex + bullet covering the D-008 runner-side gate, `harnessMode`, the `CODEX_HOME` credential write, the + `CODEX_SQLITE_HOME` redirect, and the in-VM Daytona home. + +## E. Whole-branch quality sweep + +`/simplify` ran as a single-pass inline review (the Agent fan-out is unavailable in this context, so +this was NOT the 4-agent run). The desloppify pass was focused on the un-swept M4/M5 surface (M1-M3 +were desloppified per-milestone; M4 got its own `/simplify`). A mechanical slop scan of the whole +production diff (added lines) found no `TODO`/`FIXME`, no debug prints, no swallowed errors, no +new `any`/`as any`; the `Any` in `codex_settings.py` and the ACP `any` on session/request are +documented module conventions accepted in the M3 sweep. Deliberate sibling parity is intentional per +the standing judgment context. One simplification was considered and skipped: the explicit +`CODEX_SQLITE_HOME` on Daytona is redundant given the in-VM `CODEX_HOME` already keeps SQLite off the +durable mount, but it is kept for defensive parity with the local path and to avoid re-QA of a +proven-green path. No code changes resulted from the sweep. Suites re-run green. + +## F. Lane split + +See `lane-split-plan.md`. Recommended: four area lanes (`codex-sdk` → `codex-runner` → `codex-web` → +`codex-docs`) with disjoint file sets and no split files, PR bases chained bottom-up from `main`. +Alternative concern split named its five hard-case files (`environment.ts` is the worst, spanning all +four runner concerns). Execution is a later session in the main checkout with Mahmoud's go-ahead. + +## Open questions / for Mahmoud + +1. **Ratify the D-002 M5 amendment** (in-VM `CODEX_HOME` for managed Daytona). Implemented as the + smallest-safe version (credential off durable storage); the alternative is a cwd home plus an + early-in-destroy sandbox delete (more moving parts, weaker safety). +2. **Daytona snapshot Codex pin** (follow-up): the snapshot ships an older Codex than the pinned + runner adapter, so managed Daytona codex floats on the sandbox side. Apply the same pin to the + snapshot build (recipe is outside this repo). +3. **Managed connection resolver** ("connection 'openai-managed' not found" for an explicit-slug + managed connection) is broken in this deployment, harness-independent, and blocks the product-path + Daytona tool run. Likely a deployment/EE issue predating this milestone; worth a separate look. +4. **Lane split** choice: area (recommended) vs concern.

The run flows through four layers: + +1. **The agent service** (`services/oss/src/agent/app.py`) parses the request into an + `AgentTemplate` and calls the SDK's agent runtime. +2. **The Python SDK** (`sdks/python/agenta/sdk/agents/`) turns the neutral template into + a harness-specific config and serializes one `/run` request + (`sdks/python/agenta/sdk/agents/utils/wire.py:82`, `request_to_wire`). +3. **The runner** (`services/runner/`, a Node sidecar) receives `/run`, builds a run + plan, prepares a sandbox and workspace, and drives one turn. +4. **The sandbox-agent daemon** (the pinned `sandbox-agent` npm package plus its Rust + CLI binary) spawns the harness behind an ACP bridge (ACP is the Agent Client + Protocol, the JSON-RPC protocol between the daemon and a harness; Claude sits behind + Zed's `claude-agent-acp` bridge, Pi behind `pi-acp`) and streams `session/update` + events back. + +The wire contract between layers 2 and 3 is `services/runner/src/protocol.ts`, hand +mirrored in `sdks/python/agenta/sdk/agents/utils/wire.py` and pinned by golden fixtures +in `sdks/python/oss/tests/pytest/unit/agents/golden/` that both sides assert +(`test_wire_contract.py` and `services/runner/tests/unit/wire-contract.test.ts`). The +TypeScript test has a compile-time key guard, so a drifted `protocol.ts` fails `tsc`. +Adding a harness that adds or removes wire fields means updating the golden, both type +files, and both contract tests together (`services/runner/CLAUDE.md`). + +## 2. The harness abstraction in the Python SDK + +All paths in this section are under `sdks/python/agenta/sdk/agents/`. + +### 2.1 Harness identity + +- `HarnessType` (`dtos.py:45`) is the enum of runtime selectors: `pi_core`, `claude`, + `pi_agenta`. The value is the wire string the runner reads. `coerce` accepts loose + strings from the playground. +- `HARNESS_IDENTITIES` (`dtos.py:92`) gives each harness a versioned slug + (`agenta:harness::v0`) and a display name. This single list feeds the + `harnesses` catalog the frontend dropdown renders + (`api/oss/src/resources/workflows/catalog.py:252`, `GET /catalog/harnesses/`), so a + new entry here surfaces in the UI with no bespoke frontend work. +- `SandboxAgentBackend.supported_harnesses` (`adapters/sandbox_agent.py:126`) is the + backend-side allowlist; a new harness must be added there or `make_harness` refuses + it. + +### 2.2 The harness adapters + +`adapters/harnesses.py` holds one adapter class per harness plus the +`make_harness(harness_type, environment)` factory (`adapters/harnesses.py:163`) and the +`_HARNESSES` registry (`adapters/harnesses.py:156`). Each adapter's single job is +`_to_harness_config`: project the neutral `SessionConfig` onto that harness's own +config class. + +`ClaudeHarness` (`adapters/harnesses.py:88`) is the template Codex mirrors: + +- It drops Pi built-in tool names with a warning (built-ins are a Pi concept; shipping + a name the harness cannot honor would be a silent lie). +- It threads instructions, model, resolved connection, tool specs, tool callback, MCP + servers, skills, sandbox permission, the runner permission default, and the harness's + own `harness_permissions` slice onto a `ClaudeAgentTemplate`. +- It contains no Claude-specific parsing; that lives in the config class and + `claude_settings.py`. + +### 2.3 The harness config classes and their wire methods + +`HarnessAgentTemplate` (`dtos.py:681`) is the base config a backend plumbs verbatim. +The wire methods each contribute one slice of the `/run` payload, and each is omitted +when empty so an unchanged config yields a byte-identical payload (the codebase calls +this the golden wire contract): + +- `wire_permissions` (`dtos.py:745`) emits the runner permission plan: + `{"permissions": {"default": , "rules": [...]}}`. The default comes from + `runner.permissions.default` in the template (`allow` / `ask` / `deny` / + `allow_reads`, `dtos.py:111`); the rules come from + `permission_rules.wire_author_permission_rules`. +- `wire_tools` (`dtos.py:753`) is abstract; each config shapes its own tool fields. + `ClaudeAgentTemplate.wire_tools` (`dtos.py:919`) emits `tools: []` (no Pi + built-ins), `customTools` (the resolved specs, delivered over MCP), `toolCallback`, + and spreads `wire_permissions`. +- `wire_harness_files` (`dtos.py:786`) emits the generic `harnessFiles` array: + `{path, content}` entries the runner writes blind into the session working directory + before the session starts. This is the seam where per-harness config-file rendering + happens in Python; the runner has no harness knowledge. The base implementation + returns `{}`; `ClaudeAgentTemplate.wire_harness_files` (`dtos.py:929`) overrides it + to render `.claude/settings.json` via `claude_settings.build_claude_settings_files`. +- `wire_mcp`, `wire_skills`, `wire_sandbox_permission`, `wire_model_ref`, + `wire_resolved_connection`, `wire_prompt` follow the same omit-when-empty pattern + (`dtos.py:757` onward). + +`AgentTemplate.harness_permissions` (`dtos.py:608`) is the selected harness's +first-class permission slice, parsed from `harness.permissions` in the authored +template (`dtos.py:1196`, `_parse_harness_slice`); `harness_extras` is the escape-hatch +bag (Pi's `system` / `append_system` live there). Only the selected harness's slice is +carried; there is no keyed-by-harness bag anymore. + +The execution selector objects (`harness` / `sandbox` / `runner`) are a CLOSED key set: +an unknown key inside them is a loud HTTP 400 (`dtos.py:1117`, +`_SELECTOR_ALLOWED_KEYS`, and `AgentTemplateShapeError` at `dtos.py:124`). Adding a +Codex-specific selector key would have to extend that set deliberately. + +### 2.4 The permission-rule derivation for Claude (the pattern Codex must mirror) + +`adapters/claude_settings.py` renders the Claude permission settings file. Its module +docstring (`claude_settings.py:1`) is the canonical statement of the pattern. The file +merges four rule sources into one `.claude/settings.json`, in three named layers: + +- **Layer 1, the author's options**: the harness's first-class `permissions` slice + (`harness.permissions` in the template): a `default_mode` plus per-tool `allow` / + `deny` / `ask` pattern strings in Claude's own rule syntax (for example + `Bash(rm:*)`). Parsed by `permission_rules.parse_author_permissions` + (`permission_rules.py:25`); valid modes are Claude's own four + (`default` / `acceptEdits` / `plan` / `bypassPermissions`, + `permission_rules.py:8`). The deliberate philosophy: authors write harness-native + permission options, not an Agenta-invented vocabulary. +- **Layer 2, rules derived from the sandbox boundary**: `sandbox_permission` (the + declared sandbox security policy, `dtos.py:158`) is reinforced as harness tool + rules (`claude_settings.py:75`): restricted network denies `WebFetch` / `WebSearch`; + read-only or off filesystem denies `Write` / `Edit`. A safety floor, not the primary + enforcement (the sandbox provider is). +- **Layer 3, rules derived from tool-level permissions**, two sub-sources: + - per-MCP-server `permission` becomes a whole-server `mcp__` rule + (`claude_settings.py:102`); + - each resolved executable tool's `permission` becomes a per-tool + `mcp__agenta-tools__` rule (`claude_settings.py:134`). This one is + load-bearing (finding F-046 in the docstring): Claude Code's own permission gate + fires BEFORE the runner's relay ever sees a tool call, so without a rendered + `allow` rule an allow-tool would always park for approval. `client` tools + (browser-fulfilled) render allow-unless-denied because the runner's pause seam is + their authoritative ask. + +`build_claude_settings_files` (`claude_settings.py:205`) merges author rules first, +then derived rules, dedupes, and emits the smallest valid file, or `[]` when there is +nothing to write. `SETTINGS_PATH` is `.claude/settings.json` relative to the session +cwd (`claude_settings.py:49`). The internal MCP server name `agenta-tools` +(`claude_settings.py:60`, `INTERNAL_TOOL_MCP_SERVER`) is a cross-language coupling with +the runner (`services/runner/src/engines/sandbox_agent/mcp.ts:70`). + +Why a file in the cwd and not ACP metadata: the Claude ACP adapter builds its SDK query +with `settingSources: ["user", "project", "local"]`, so it reads +`/.claude/settings.json`; the sandbox-agent daemon strips ACP `_meta`, so the cwd +file is the only clean config path (`claude_settings.py:4`). + +`permission_rules.wire_author_permission_rules` (`permission_rules.py:39`) is the +second consumer of the same authored slice: it projects the non-MCP author patterns +into the runner permission plan (`permissions.rules` on the wire), skipping `mcp__` +patterns to avoid double-counting tools already covered by MCP-server or tool-spec +permissions. + +### 2.5 The capability table, model catalog, and provider-env maps + +`capabilities.py` is the per-harness connection-capability table: + +- `HARNESS_CONNECTION_CAPABILITIES` (`capabilities.py:214`) has one record per + harness: `providers` (families it can reach), `deployments` (`direct` / `custom` / + `bedrock` / `vertex_ai`), `connection_modes` (`agenta` / `self_managed`), + `model_selection` (`provider/id` for Pi, `alias` for Claude), `models` (the + selectable ids per family), `model_catalog`, and optional `mcp`. +- The Claude record (`capabilities.py:235`) is the closest shape to a future Codex + record: single provider family, alias model selection, and an `mcp` block. + `HarnessMCPCapabilities` (`capabilities.py:177`) declares user-MCP-server support + (HTTP connection, `none` or `header_secret_refs` credentials); only Claude carries + it, which is what lets the UI offer user MCP servers on Claude. +- `model_catalog` wiring: `_model_catalog(harness)` (`capabilities.py:131`) loads + curated per-model entries from `model_catalog.py`, which reads JSON data files under + `data/` (`model_catalog.py:11`): `pi_models.generated.json` plus a curated overlay + for Pi, `claude_models.curated.json` for Claude. `model_catalog_entries` + (`model_catalog.py:147`) returns `[]` for an unknown harness, so a Codex harness + needs both a data file and a branch there (plus the `sync-model-catalog` skill that + owns the data). +- `PI_SUBSCRIPTION_MODELS` (`capabilities.py:72`) is where Codex already appears + today, as a MODEL PROVIDER inside Pi, not as a harness: the `openai-codex` provider + (OpenAI's ChatGPT/Codex subscription) with explicit ids (`gpt-5.6-sol` through + `gpt-5.3-codex-spark`). Pi authenticates it through its own OAuth login file + (`~/.pi/agent/auth.json`), never a vault key, which is why the provider's env group + in the runner is empty (section 3.5). +- `PROVIDER_ENV_VARS` (`capabilities.py:114`) is the canonical provider-to-env-var + map; `platform/secrets.py` and `connections/resolver.py` import it so the three + cannot drift. The runner's `PROVIDER_ENV_VAR_GROUPS` mirrors it by hand (a + documented cross-language coupling, `services/runner/src/engines/sandbox_agent/daemon.ts:128`). +- Enforcement: `harness_allows_provider` / `_mode` / `_deployment` / `_pair` + (`capabilities.py:284` onward) are consumed server-side in + `handler.py:128` through `handler.py:150`, so a direct API caller is rejected with + the same rules the UI filter uses. An unknown harness is CLOSED (no capability). + `HARNESS_CUSTOM_DEPLOYMENT_PROVIDERS` (`capabilities.py:328`) restricts the `custom` + deployment cross-product (Pi custom is openai-only, Claude custom is + anthropic-only). + +## 3. The runner + +All paths in this section are under `services/runner/src/` unless stated. The runner is +the Node sidecar that serves `/run`; the engine lives in `engines/sandbox_agent/` with +`engines/sandbox_agent.ts` as a re-export facade. + +### 3.1 The flow of one run + +`runSandboxAgent` (`engines/sandbox_agent/engine.ts:33`) is the cold path: +`acquireEnvironment`, then `runTurn`, then `env.destroy()`. The keep-alive dispatch in +`server.ts` reuses the same two halves across turn boundaries. `shouldPark` +(`engine.ts:16`) decides whether a completed turn's environment may be pooled. + +- `run-plan.ts` (`buildRunPlan`, `run-plan.ts:265`) turns the request into a pure + `RunPlan`: harness-to-agent mapping, cwd and relay dirs, tool specs, permission + bookkeeping, and every fail-loud gate (section 3.2). +- `environment-setup.ts` (`prepareEnvironmentSetup`, `environment-setup.ts:56`) signs + the durable mounts, builds the plan, builds the daemon environment (section 3.5), + prepares local Pi assets, and assembles the mutable `SessionEnvironment` record. +- `environment.ts` (`acquireEnvironment`, `environment.ts:254`) starts the sandbox via + `SandboxAgent.start`, uploads Daytona assets, mounts durable storage, prepares the + workspace (section 3.4), probes capabilities, builds the session MCP server list + (section 3.6), opens the ACP session (`createSession` or the patched + `resumeSession`), applies the model (`model.ts`, exact match first, then suffix + match), and attaches session-lifetime `onEvent` / `onPermissionRequest` listeners + that demux into `env.currentTurn`. +- `run-turn.ts` (`runTurn`, `run-turn.ts:80`) runs one turn: fresh tracing run, the + per-turn pause controller and approval responder, the tool relay, then races the + prompt against the pause signal and the run-limit deadlines. + +### 3.2 Harness mapping and the fail-loud gates in the run plan + +The harness identity maps to the ACP agent id the daemon knows +(`run-plan.ts:302`): `pi_core` and `pi_agenta` map to `pi`; anything else passes +through unchanged, so `claude` maps to `claude` and a future `codex` would already +reach the daemon as `codex`. A debug assertion pins the Pi mapping +(`run-plan.ts:308`); the old PR relaxed it to `harness.startsWith("pi_")`, which is the +shape a third harness needs. + +Gates that fire before any resource is created (each is a named-constant message, the +repo's fail-loud convention): + +- Disabled sandbox provider (`run-plan.ts:287`). +- Daytona plus subscription auth: `credentialMode === "runtime_provided"` on Daytona is + rejected (`run-plan.ts:333`, `DAYTONA_SUBSCRIPTION_UNSUPPORTED_MESSAGE` at + `run-plan.ts:80`). Subscription state lives only in the runner container and never + ships to a third-party sandbox. +- Local subscription without a mount: a local `runtime_provided` run requires the + harness's config-dir env var to be set (`run-plan.ts:341`), and the var is chosen by + harness: `CLAUDE_CONFIG_DIR` when the ACP agent is `claude`, else + `PI_CODING_AGENT_DIR` (`run-plan.ts:343`). This binary choice is one of the concrete + places a Codex harness must add a branch (a `codex` run today would demand + `PI_CODING_AGENT_DIR`, which is wrong). +- Unenforceable boundaries: declared `filesystem` policy always errors; restricted + `network` errors on the local sandbox (`run-plan.ts:370`, `run-plan.ts:379`). +- Code tools are refused (`run-plan.ts:389`); user MCP servers on Pi are refused + (`run-plan.ts:397`); the `agenta-tools` name is reserved (`run-plan.ts:407`); + non-Pi tools on a non-Daytona remote sandbox are refused (`run-plan.ts:417`). + +`legacyHarnessApiKeyVar` (`run-plan.ts:350`) names the api-key env var the harness +reads by default: `ANTHROPIC_API_KEY` for claude, `OPENAI_API_KEY` for everything +else. Codex reads `OPENAI_API_KEY`, so the existing fallback already fits. + +The plan carries `harnessFiles` verbatim (`run-plan.ts:165`); nothing in the runner +parses them. + +### 3.3 Where local harness assets are prepared + +`environment-setup.ts` is the local asset-prep site: + +- Pi: `prepareLocalPiAssets` (`pi-assets.ts:608`, called at + `environment-setup.ts:251`) builds a throwaway per-run Pi agent dir (settings, + extension bundle, models.json, system prompts) unless the run is subscription-backed, + in which case Pi runs out of the operator's mounted login directly. +- Claude: no local asset step exists. Its settings ride `harnessFiles` into the cwd, + its credential rides `secrets` as env, and its connection extras ride + `applyClaudeConnectionEnv` (`runtime-policy.ts:52`): `ANTHROPIC_BASE_URL`, the + Bedrock/Vertex flags, and `ENABLE_TOOL_SEARCH=false` (a Claude SDK workaround so + `agenta-tools` schemas are loaded before the first call). +- A local Claude subscription run deliberately makes no per-run copy of the login: + Claude refreshes its OAuth token mid-run and writes it back, so the mount must be the + live read-write directory (`environment-setup.ts:278`, comment block). +- Daytona: `prepareDaytonaPiAssets` (`daytona.ts`, called at `environment.ts:699`) + uploads the Pi login, extension, and models.json into the remote sandbox; for a + non-Pi harness with tools, `uploadToolMcpAssets` (`environment.ts:713`) uploads the + in-sandbox stdio MCP shim instead. + +A Codex asset step (writing `auth.json` from the resolved key, per section 6) would sit +beside `prepareLocalPiAssets` in `environment-setup.ts`, with its cleanup in +`environment.destroy` (`environment.ts:292`). + +### 3.4 Workspace preparation and who writes the harness files + +`prepareWorkspace` (`workspace.ts:49`) materializes the cwd on both local and Daytona: + +- The instructions file name is harness-aware (`workspace.ts:57`): `CLAUDE.md` for the + claude agent (the Claude SDK memory loader reads only `CLAUDE.md`), `AGENTS.md` for + every other harness. Codex reads `AGENTS.md` natively (TO VERIFY IN SPIKE), so the + existing default likely fits without a branch. +- Every `harnessFiles` entry is written blind under the cwd (`workspace.ts:88` for + Daytona, `workspace.ts:128` for local). This is the answer to "who writes + `.claude/settings.json`": the Python adapter renders it, the runner's + `prepareWorkspace` writes it. +- Skills: Pi consumes an immutable snapshot; every non-Pi harness gets project-local + `./skills/` copies (`workspace.ts:56`), so a codex run with skills + would today produce `.codex/skills/`; whether Codex reads that is unknown (TO VERIFY + IN SPIKE). + +### 3.5 The daemon environment and least-privilege credential scoping + +`daemon.ts` builds the environment the local daemon is born with and resolves the +daemon binary: + +- `resolveDaemonBinary` (`daemon.ts:26`) finds the platform CLI binary shipped by the + `@sandbox-agent/cli-*` packages, preferring `SANDBOX_AGENT_BIN`. +- `KNOWN_PROVIDER_ENV_VARS` (`daemon.ts:76`) is the CLEAR set: every provider api key, + every Anthropic auth/OAuth var, and the AWS/GCP/Azure cloud groups. On a managed run + (`credentialMode === "env"`) `buildDaemonEnv` copies NONE of them; the caller then + applies only the resolved `plan.secrets` (`environment-setup.ts:170`). This is the + clear-then-apply discipline (Security rule 5 of the provider-model-auth design). The + set has no `CODEX_API_KEY` entry today. +- `PROVIDER_ENV_VAR_GROUPS` (`daemon.ts:132`) is the least-privilege INHERIT map for + non-managed runs: a run that declared provider X inherits only X's vars + (`inheritableProviderEnvVars`, `daemon.ts:188`). The `openai-codex` group is + deliberately empty (`daemon.ts:151`): Pi's ChatGPT/Codex subscription authenticates + from its OAuth file, not env. `DEPLOYMENT_ENV_VAR_GROUPS` (`daemon.ts:160`) adds the + cloud group per deployment. An unknown provider falls back to the whole known set. +- Config-dir env vars are inherited on every run because they are paths, not + credentials: `PI_CODING_AGENT_DIR` and `CLAUDE_CONFIG_DIR` (`daemon.ts:263`). There + is no `CODEX_HOME` line; a Codex harness needs one. +- Sandbox-provider infra creds are force-blanked on every run + (`KNOWN_SANDBOX_ENV_VARS`, `daemon.ts:116`), because the daemon's local provider + spawns with `{...process.env, ...options.env}`. + +### 3.6 Tool delivery: the agenta-tools channel + +Backend-resolved tools reach a non-Pi harness through the runner's internal MCP server, +named `agenta-tools` on every transport (`engines/sandbox_agent/mcp.ts:70`): + +- Local: `buildToolMcpServers` (`tools/mcp-bridge.ts:78`) starts a loopback HTTP MCP + server on the runner host advertising the run's resolved specs, with a per-server + bearer token; the session's MCP list carries a `type: "http"` entry pointing at it. + Tool calls relay back into the runner (`tools/relay.ts` executes them server-side + with the private specs and callback auth held in runner memory; + `relay-guard.ts` re-checks permissions so a forged relay file cannot execute a + denied tool). +- Daytona: the loopback URL is unreachable from inside the sandbox, so the channel is + an uploaded in-sandbox stdio shim instead (`buildInternalToolMcpEntry`, + `mcp.ts:108`; assets uploaded by `tool-mcp-assets.ts`). The shim writes relay + request files the runner-side loop executes. +- `buildSessionMcpServers` (`mcp.ts:290`) assembles the session list: the internal + channel (Layer 1) plus the user's own declared HTTP MCP servers (Layer 2, + `toAcpMcpServers` with an SSRF guard, `mcp.ts:159`). Pi gets `[]` (its tools ride + the bundled extension). The two layers gate independently by design. +- Capability gating: `probeCapabilities` reads the daemon's `AgentInfo.capabilities`; + when the probe is empty the static fallback treats every non-`pi` agent as + MCP-capable (`capabilities.ts:100`, comment: "pi-acp does not forward MCP, + Claude/Codex do"). `assertRequiredCapabilities` fails loud when a run carries tools + the harness cannot receive. + +Claude addresses these tools as `mcp__agenta-tools__`, which is what the rendered +Layer 3 rules match (section 2.4). + +### 3.7 The approvals architecture + +The pieces, in the order a permission request flows: + +- The daemon forwards a harness's ACP `session/request_permission` reverse-RPC; the + session-lifetime listener routes it into the active turn + (`environment.ts:1084`, `session-events.ts`). +- `attachPermissionResponder` (`acp-interactions.ts:108`) classifies the request. + Detection order: on a Pi run (marked by the presence of `piToolSpecsByName`), a gate + riding Pi's `ctx.ui.confirm` dialog is parsed from its envelope and fails closed on + any mismatch; otherwise the base path builds a `GateDescriptor` from the ACP tool + call plus the run's real resolved specs (`buildGateDescriptor`, + `acp-interactions.ts:515`, stripping the `mcp__agenta-tools__` prefix to find the + spec). Client tools get their own pause; everything else goes to the responder's + policy (`responder.ts`, fed by the wire `permissions` plan and stored decisions). +- A verdict of `pendingApproval` pauses the turn: `pauseUserApproval` + (`acp-interactions.ts:152`) emits one `interaction_request` event, records a durable + interaction row, and fires `onPause`. A pause sends NO reply to the harness + (replying `reject` would clobber the approval prompt, the F-024 bug). +- `ParkedApprovalGateType` (`acp-interactions.ts:25`) is a CLOSED two-value union: + `"claude-acp-permission" | "pi-acp-permission"`. The base (non-Pi) path hardcodes + `"claude-acp-permission"` (`acp-interactions.ts:432`), and the keep-alive dispatch + in `server.ts:668` resumes only those two values. A Codex gate today would be + labeled a Claude gate; the design must either add a `codex` value or generalize the + base label. This union, the classification, and the resume check are the three + coupled sites. +- `PendingApprovalPauseController` (`pause.ts:11`) is the per-turn pause latch: first + pause wins, it runs the destroy callback (which in park mode skips session + teardown), suppresses later frames for paused tool-call ids, and exposes `signal` + that the prompt race in `runTurn` awaits (`run-turn.ts:482`). +- Park and resume: `ParkedApproval` (`runtime-contracts.ts:113`) records the gate + type, ACP permission id, tool-call id, args, interaction token, and the still-pending + `prompt()` promise. `ResumeApprovalInput` (`runtime-contracts.ts:131`) is the + resume shape; `runTurn` answers the parked gate on the live session via + `session.respondPermission` and continues the original prompt + (`run-turn.ts:437`). Only a single-gate pause parks + (`env.approvalGateCount`, `runtime-contracts.ts:231`). +- Client tools (browser-fulfilled) ride the same `agenta-tools` channel but pause at + the MCP `tools/call` instead (`client-tools.ts`, `tools/client-tool-relay.ts`); they + are never parked across turns. + +### 3.8 The subscription mount contract + +Subscription auth (the harness signs itself in from the operator's own login state, +`credentialMode === "runtime_provided"`) is local-only by policy: + +- Daytona rejection: `run-plan.ts:333` (section 3.2). +- The mount contract: the operator sets the harness's config-dir env var on the runner + container to a read-write mount of the login (`CLAUDE_CONFIG_DIR` for Claude, + `PI_CODING_AGENT_DIR` for Pi; `run-plan.ts:341`), the daemon env inherits it + (`daemon.ts:263`), and the harness reads AND refreshes its OAuth state in place + (`environment-setup.ts:278`). `plan.sourcePiAgentDir` defaults to `~/.pi/agent` + (`run-plan.ts:536`). +- The compose files carry these vars for the dev/gh stacks + (`hosting/docker-compose/oss/docker-compose.dev.yml` and siblings; + `hosting/kubernetes/helm/templates/runner-deployment.yaml`). + +## 4. What the pinned sandbox-agent daemon supports for Codex today + +Source: the installed `sandbox-agent@0.4.2` package and its +`@sandbox-agent/cli-linux-x64@0.4.2` binary in the main checkout's +`services/runner/node_modules` (same pin as this worktree's +`services/runner/package.json:36`), plus the repo patch +`services/runner/patches/sandbox-agent@0.4.2.patch`. The binary was inspected via +strings only; behavioral claims from it are structural, not tested. + +- **The JS SDK knows codex as a first-class agent.** `DEFAULT_AGENTS = ["claude", + "codex"]` in the SDK's provider chunk, and its `autoAuthenticate` answers ACP auth + methods with ids `codex-api-key`, `openai-api-key`, or `anthropic-api-key`. +- **The daemon binary can spawn five agents**: `claude`, `codex`, `amp`, `pi`, + `cursor` (display names "Claude Code", "Codex CLI", ...). Its embedded adapter + registry (`adapters.json` baked into the binary) maps `codex` to the npm package + `@zed-industries/codex-acp`, pinned version `0.1.0` (claude maps to + `@zed-industries/claude-agent-acp` 0.20.0, pi to `pi-acp` 0.0.23). +- **Adapter resolution order** (log strings in the binary): builtin, then a PATH + binary hint, then npm install from the ACP registry + (`cdn.agentclientprotocol.com/registry/v1/latest/registry.json`), then a fallback + launcher. The runner today satisfies claude and pi from PATH: it prepends its own + `node_modules/.bin` (which contains `claude-agent-acp` and `pi-acp`) to the daemon's + PATH (`daemon.ts:257`). There is NO `codex-acp` binary in the runner's + `node_modules/.bin`, so a codex session would fall to the runtime npm-install path + unless the runner vendors the bridge the same way (TO VERIFY IN SPIKE, question 1). +- **Codex CLI auto-install**: the binary downloads the codex CLI from + `github.com/openai/codex/releases/.../codex-` on demand + (`agent_manager.install_codex` strings), with a `sandbox-agent install-agent ` + CLI for pre-baking. Runtime network access from the runner image is therefore a + deployment question (TO VERIFY IN SPIKE, question 1). +- **Credential detection**: the daemon's credentials probe reads `.codex/auth.json` + and looks for an `OPENAI_API_KEY` field or a `tokens.access_token` field (OAuth), + and separately knows the env vars `CODEX_API_KEY` and `OPENAI_API_KEY`. This + matches the old PR's auth-file finding (section 6). +- **An embedded codex model catalog** lists `gpt-5.x-codex` ids (for example + `gpt-5.3-codex`, `gpt-5.3-codex-spark`, `-fast` / `-high` / `-xhigh` variants) with + `"defaultModel": "gpt-5.3-codex"`. The ids visible in the 0.4.2 binary are older + than Pi's current `openai-codex` list (`capabilities.py:72`), so the real list must + be probed live (TO VERIFY IN SPIKE, question 8). +- **The repo patch** (`patches/sandbox-agent@0.4.2.patch`) is harness-agnostic plumbing + the runner relies on: `session/load` support behind the agent's `loadSession` + capability (with a `claudeCode.options.resume` `_meta` hint that is Claude-specific), + pause-instead-of-destroy on reconnect failure, process-group kill and detached spawn + for the local daemon. Whether `codex-acp` advertises `loadSession` decides whether + session continuity works for Codex (TO VERIFY IN SPIKE, question 7). + +## 5. How subscription authentication works today and where Codex plugs in + +Two harnesses authenticate from a personal subscription today, both through the same +mechanism (section 3.8): the operator logs the harness in once, mounts the login into +the runner container read-write, and points the harness's config-dir env var at it. + +- Claude: login state in `~/.claude` (`.credentials.json` with a `claudeAiOauth` + block); env var `CLAUDE_CONFIG_DIR`. Recipe and rationale: + `docs/design/agent-workflows/projects/subscription-sidecar/README.md` (the + "subscription sidecar" is a second runner container started with these mounts for + dev/test; note that document predates the `services/agent` to `services/runner` + rename and the read-write mount requirement). +- Pi with the `openai-codex` provider: login state in `~/.pi/agent/auth.json` + (created by `pi` then `/login` with a ChatGPT account); env var + `PI_CODING_AGENT_DIR`. The reachable models are `PI_SUBSCRIPTION_MODELS` + (`capabilities.py:72`); the runner normalizes a bare id onto Pi's + `openai-codex/` model (`model.ts:93`). This is Codex-the-subscription through + Pi-the-harness; it shares nothing on disk with the Codex CLI's own login. + +A Codex-harness self-managed path would plug into the same five seams: + +1. A config-dir env var for the mount (Codex's own is `CODEX_HOME`, default + `~/.codex`; TO VERIFY IN SPIKE, question 4) added to the `run-plan.ts:343` branch + and inherited in `buildDaemonEnv` beside `CLAUDE_CONFIG_DIR` (`daemon.ts:263`). +2. The login file itself: `~/.codex/auth.json`, which the daemon's credential probe + already reads (section 4). +3. The `capabilities.py` record advertising `self_managed` for the codex harness (the + `connection_modes` axis, section 2.5), so the app layer stops rejecting the run + before it reaches the runner. +4. The Daytona rejection, which needs no change: `run-plan.ts:333` keys on + `credentialMode`, not on the harness. +5. The provider env group: a `codex`-harness run resolves provider `openai`, whose + inherit group is `["OPENAI_API_KEY"]` (`daemon.ts:133`); an OAuth-only run needs no + env at all, mirroring the empty `openai-codex` group. + +## 6. Salvage notes from the stale PR stack + +The stack: #5042 (harness-agnostic remote asset-prep seam), #5043 (Codex harness on +the local sandbox), #5049 (Codex on Daytona), #5050 (Codex on E2B), all by junaway, +July 2, based on the dead `big-agents` trunk. Read via `gh pr diff`, read-only. The +code targets a pre-split runner (a monolithic `engines/sandbox_agent.ts`) and a +pre-migration wire contract, so nothing rebases; the list below is what to re-type +against main and what to discard. + +### Directly reusable on main (from #5043) + +- **The auth-file insight**, the stack's most valuable finding, stated in its docs and + implemented in `writeCodexAuthFile`: the codex CLI reads `~/.codex/auth.json` as a + FILE; env injection alone is insufficient. Managed runs must write + `{"OPENAI_API_KEY": ""}` into it before the daemon starts (dir `0700`, file + `0600`), the field name is always `OPENAI_API_KEY` regardless of the source var, and + the run's teardown may delete the file only when that run created it (never a + pre-existing self-managed login). Self-managed runs verify the file exists and warn + when absent. A dir-override env var (`AGENTA_AGENT_CODEX_DIR` in the PR) kept a + managed run from clobbering a personal login in a shared home. +- **The SDK skeleton**: `HarnessType.CODEX = "codex"`, the `HARNESS_IDENTITIES` entry + (`agenta:harness:codex:v0`, name "Codex"), `CodexHarness` mirroring `ClaudeHarness` + (drop built-ins with a warning, tools over MCP), `CodexAgentTemplate` mirroring + `ClaudeAgentTemplate`, registration in `_HARNESSES` and the `adapters/__init__` and + `agents/__init__` exports. All of it re-types cleanly minus the permission field + (below). +- **The runner mapping change**: `codex` passes through to ACP agent `codex` (main's + mapping already does this); the Pi identity assertion relaxed to + `harness.startsWith("pi_") === (acpAgent === "pi")`. +- **Test shapes**: a `run_request.codex.json` golden plus symmetric assertions in + `test_wire_contract.py` and `wire-contract.test.ts`; `make_harness("codex")` + adapter tests; `buildRunPlan` tests asserting `acpAgent === "codex"`, + `legacyHarnessApiKeyVar === "OPENAI_API_KEY"`, `isPi === false`; auth-file writer + tests covering modes `0600`/`0700`, the created-vs-preexisting return, the + `CODEX_API_KEY` fallback source, and the self-managed missing-file warning. +- **The capability-table entry shape**: providers `["openai"]`, deployments + `["direct"]`, both connection modes. (The PR's `model_selection: "id"` was a new + third value; whether Codex selection is bare-id or alias-like is a design call.) +- **The adapter doc skeleton** (`documentation/adapters/codex.md` in the PR): correct + structure, stale specifics. + +### Obsolete or wrong on main + +- **The `permissionPolicy` wire field.** The PR added `permission_policy: "auto" | + "deny" | ...` on `CodexAgentTemplate` and a `permissionPolicy` key on the wire. + Main has no such field: permissions ride the structured `permissions: {default, + rules}` plan (`protocol.ts:476`) plus harness-rendered `harnessFiles`. A Codex + permission story on main means a `codex_settings.py` sibling of + `claude_settings.py` rendering Codex's own config, not a scalar policy field. +- **The monolith wiring.** The PR patches `engines/sandbox_agent.ts` directly + (`prepareLocalCodexAssets` called inside `runSandboxAgent`, cleanup in its + `finally`) and puts the codex helpers in `pi-assets.ts`. Main split the engine: + the asset step belongs in `environment-setup.ts`, the cleanup in + `environment.destroy` (`environment.ts:292`), and a module-level `CODEX_DIR` + constant read at import time conflicts with per-run env handling (the PR's own tests + needed `vi.resetModules` to cope). +- **Stale model ids**: `gpt-4.5`, `gpt-4o`, `o3`, `o4-mini` are gone; + the current subscription list lives at `capabilities.py:72` and the true harness + list must come from a live probe. +- **Missing against main's current bar**: no `model_catalog` data file, no + `HarnessMCPCapabilities` decision for user MCP servers, no `permissions` object in + the golden (main's Claude golden carries it), no approvals/park work, no + subscription mount branch, and the PR's `harness_allows_provider` comment claims + absent entries are permissive when main is closed. +- **#5042's remote-assets seam** (`prepareRemoteHarnessAssets`, + `writeCodexAuthToSandbox`): the idea (a harness-agnostic remote credential-prep + seam) is sound, but the code targets the monolith and predates + `uploadToolMcpAssets` and the current Daytona asset flow; re-derive it, do not port + it. **#5049/#5050**: Daytona must be re-planned against the current + `prepareDaytonaPiAssets` / shim flow, and E2B has no sandbox provider on main at + all (also declared a non-goal in `context.md`). +- Path churn throughout: the stack says `services/agent/`; main says + `services/runner/`. + +## 7. Codex CLI and codex-acp facts relevant to the design + +Split by evidence class. "Verified" means read from the pinned daemon binary or this +repo; everything else is background knowledge and carries TO VERIFY IN SPIKE. + +Verified here: + +- The ACP bridge is `@zed-industries/codex-acp`; the pinned daemon installs version + `0.1.0` from the ACP registry (section 4). +- The daemon treats `.codex/auth.json` with either an `OPENAI_API_KEY` field or a + `tokens.access_token` field as a valid codex credential, and knows `CODEX_API_KEY` / + `OPENAI_API_KEY` as codex env vars (section 4). +- The daemon's codex catalog defaults to `gpt-5.3-codex` at pin time (section 4). +- The codex CLI installs from GitHub releases (`openai/codex`) (section 4). + +Background knowledge, TO VERIFY IN SPIKE: + +- **`CODEX_HOME`**: the env var that relocates Codex's state directory, default + `~/.codex`. Both `config.toml` (run config) and `auth.json` (login) live in it, + along with logs and session rollouts. Whether config and login can be split across + two directories matters for the mount layout (question 4). +- **`config.toml` keys**: `model`; `approval_policy` with values `untrusted`, + `on-failure`, `on-request`, `never`; `sandbox_mode` with values `read-only`, + `workspace-write`, `danger-full-access`; a `[sandbox_workspace_write]` table with + `network_access`; `[mcp_servers.]` tables with `command` / `args` / `env` for + stdio servers, and in newer releases HTTP transport fields for remote servers; + `[projects.""]` trust markers; named `[profiles.]`. Exact key names and + which Codex version the pinned bridge drives are unverified (questions 3, 5, 6). +- **`auth.json` contents by login mode**: an API-key login (`codex login --api-key`) + yields `{"OPENAI_API_KEY": "sk-..."}`; a ChatGPT OAuth login (`codex login`, browser + flow) yields a `tokens` object (`id_token`, `access_token`, `refresh_token`, + `account_id`) plus `last_refresh`, with `OPENAI_API_KEY` null or absent. Codex + refreshes the OAuth token and rewrites the file in place, which would make the + read-write mount requirement identical to Claude's (questions 2, 4). +- **Approvals over ACP**: Codex raises exec/patch approval requests; `codex-acp` is + expected to surface them as ACP `session/request_permission`. The shape of the + request (title, tool-call id, `availableReplies`) decides how the runner's base-path + classification and the park record fit (question 6). +- **AGENTS.md**: Codex reads `AGENTS.md` from the project root natively, plus a global + `$CODEX_HOME/AGENTS.md` (question 10). + +## 8. Open questions for the spike + +Numbered so the spike findings can reference them. + +1. **Bridge and CLI provisioning.** Does a `createSession({agent: "codex"})` against + the pinned daemon auto-install the codex CLI and `codex-acp` at runtime (needs + network to GitHub and npm from inside the runner container), and does a PATH-vendored + `codex-acp` binary in the runner's `node_modules/.bin` short-circuit the install the + way `claude-agent-acp` and `pi-acp` do? Which codex-acp and codex CLI versions + actually run? +2. **Auth via env vs file.** With only `OPENAI_API_KEY` in the daemon env and no + `auth.json`, does a codex run authenticate (via the bridge's `codex-api-key` ACP + auth method), or is the auth file strictly required as the old PR found? Does a + ChatGPT-OAuth `auth.json` (tokens object, no API key) authenticate identically, and + does Codex rewrite it mid-run (token refresh)? +3. **MCP delivery.** Does the daemon pass the session's `mcpServers` list (the + `type: "http"` `agenta-tools` entry with its bearer header) through `codex-acp` to + Codex? Which MCP transports does the driven Codex version accept (stdio only, or + HTTP)? Do `tools/list` and `tools/call` round-trip, and do tool events stream as + `tool_call` / `tool_call_update` frames the tracer maps? +4. **Config and login separation.** Does `CODEX_HOME` relocate both `config.toml` and + `auth.json` together?

Hence s1's failure: with the + built-in provider and no stored auth, the adapter's `authRequired()` → true → ACP -32000. +- `authRequired()` in codex-acp is `response.requiresOpenaiAuth && !response.account` over + app-server `account/read` (bundle 26164-26170; `checkAuthorization` at 28548 runs on every + session new/load/resume). `account/read` computes `requires_openai_auth` from the ACTIVE model + provider in the app-server's own config (`app-server/src/request_processors/account_processor.rs:930-935, + 995-1013`) — which is `CODEX_HOME/config.toml`, NOT the thread config. **Therefore + `model_provider = ""` must be in the rendered config.toml** (delivering the provider + tables only through `CODEX_CONFIG` leaves account/read looking at the built-in provider and the + gate stays). `ModelProviderInfo.requires_openai_auth` defaults to false for custom entries + (`model-provider-info/src/lib.rs:132-137`), so the gate vanishes. +- Request-time precedence: `resolve_provider_auth` (`model-provider/src/auth.rs:179-197`) checks + `bearer_auth_for_provider` FIRST — `provider.api_key()` reads the `env_key` env var at call time + (`model-provider-info/src/lib.rs:283-300`, plain `std::env::var`) and wins over any + auth.json/ChatGPT auth. So even a stray auth.json would be ignored for a `env_key` provider. +- Custom providers default `supports_websockets: false`, and the probes confirm: **zero WebSocket + upgrade attempts, plain HTTP POST to `/responses` from the first request** + (`q1-listener-capture.jsonl`; contrast P3's ~7-retry ws dance on the built-in provider). One less + egress-proxy caveat. +- Model catalog, session modes, reasoning-effort options, and usage accounting are IDENTICAL under + the custom provider (same 5-model list served, `set-model` accepted; `usage` fully populated in + `q1a2` — compare s2/s3). The only observable delta: `account/read` reports no account (nothing in + the runner consumes it), and name-gated OpenAI extras (`is_openai()` string-compares the display + name, `lib.rs:389-391`) such as remote compaction are off unless the provider is named `OpenAI`. + +### Daytona placeholder composability (#5277) + +Mechanism #3 is the best possible fit for the placeholder design: the key exists ONLY as a process +environment value read at request time — and the sandbox's env is exactly where a Daytona Secret +placeholder materializes. The runner already puts the resolved key into the daemon env for managed +runs (`plan.secrets` → `buildDaemonEnv`), so no new plumbing: under #5277 the env var holds +`dtn_…placeholder…`, codex copies it verbatim into `Authorization: Bearer` (re-proven byte-exact in +`q1a`, same result as P3), and the egress proxy substitutes. Mechanisms #4 and #5 also compose (the +value they capture is whatever the env held), but they snapshot the value at login/daemon-start +rather than reading per request. Bonus for the proxy: no WebSocket upgrade to handle under #3. + +Subscription mode is untouched by all of this: ChatGPT OAuth still needs the token file, and the +approved symlink-assembly design stays as is. + +--- + +## Question 2 — the add-then-remove lifecycle on durable storage + +Context recap: Mahmoud's proposed layout for managed Daytona codex is +`CODEX_HOME = /.codex` on the durable geesefs mount (native `sessions/` rollouts durable ⇒ +native resume survives sandbox replacement, per P8b), `CODEX_SQLITE_HOME` in-VM (hard geesefs +constraint, P8a), auth.json written at session start and DELETED from the durable mount before the +sandbox is paused or destroyed. + +### a. Where the delete goes — one seam covers every orderly path + +All sandbox lifecycle exits flow through the single idempotent +`environment.destroy` closure (`services/runner/src/engines/sandbox_agent/environment.ts:291-380`); +`pauseSandbox` is invoked NOWHERE else (only environment.ts:315). Current order inside destroy: + +1. tool relay / MCP shutdown; graceful ACP `destroySession` (line 304) — after this codex is dead + and cannot rewrite auth.json; +2. `teardownDisposition(reason)` (line 306): park reasons (`clean-resumable`, `idle-expiry`, + `capacity-eviction`, `shutdown-idle` — `teardown.ts:24-37`) → `pauseSandbox()` (315); everything + else (`kill`, `failed-turn`, `aborted`, `compatibility-mismatch`, `shutdown-in-flight`) → + `destroySandbox()` (324); +3. durable-cwd unmount (329-334), workspace cleanup, then the file backstops INCLUDING today's + `rmSync(environment.codexAuthFilePath)` (371-372). + +**The delete-before-pause/destroy step belongs between (1) and (2)**: after `destroySession` +(writer dead), before `pauseSandbox`/`destroySandbox` (the sandbox and its in-VM geesefs mount are +still alive, so a delete through the sandbox FS API — `deleteFsEntry`, available on the sandbox +handle, `sandbox-agent/dist/index.d.ts:3251` — propagates to S3). Because every reason routes here, +one insertion covers: turn end that parks (server.ts `parkFreshOrDestroy`/`reparkOrEvict` → pool → +`teardown(reason)` → destroy), pool idle TTL expiry (`session-pool.ts:249`), capacity eviction +(`session-pool.ts:348-352`), explicit stop/shutdown (`destroyInFlightSandboxes`, environment.ts:158, +drains the tracked set — parked-live environments are still in `inFlightSandboxes` because only +destroy removes them), cold-replay approval pauses (stopReason `paused` → `failed-turn` → delete), +and aborts. + +Two subtleties, both real: + +- **Keep-alive pool parking is NOT a teardown.** A pool-parked environment (state `idle`) keeps the + daemon and sandbox fully alive and auth.json must remain in place for the next warm turn. The + delete point is exclusively `environment.destroy`; nothing at `pool.park` time. +- **Found gap in the CURRENT code (applies today to local durable managed codex):** the existing + backstop `rmSync(codexAuthFilePath)` at environment.ts:371 runs AFTER `unmountStorage` + (329-334). On a local durable session the path then points into the unmounted (empty) mountpoint, + so the rm is a silent no-op against the host dir and **the key file persists in the durable + store**. The proposal's delete must sit before the unmount for local (host-side rm through the + live FUSE mount) and before pause/destroy for Daytona (sandbox-API delete through the live VM). + Same fix class for both. + +### b. Crash window + +If the runner process dies without running destroy (SIGKILL, OOM, host loss), nothing deletes the +durable file: **auth.json remains in S3 indefinitely**, attached to a conversation workspace that +may never be resumed. Add-on-start only refreshes/overwrites it when the SAME session runs again; +an abandoned session's key has no reaper. Existing/planned machinery: + +- The in-flight drain (`destroyInFlightSandboxes`, environment.ts:142-171) covers orderly SIGTERM + shutdown only — it is a signal handler in the same process, useless against a hard crash. +- **#5278 (durable managed-resource reconciliation) is the designated sweeper but is a PLAN, not + code**: an OPEN docs-only PR proposing a reusable `managed_resources` domain (product-owned + intent, desired/observed state, generation-fenced worker claims, typed provider controllers; + Daytona Secrets as the first controller). Implementation is explicitly paused pending domain and + workload-auth decisions. A "durable auth.json object" would be a trivial additional controller + (desired state: absent unless a live run holds the session) — but none of it exists today. +- Without #5278, the honest statement is: the crash window is bounded only by the durable store's + own data lifecycle (today: unbounded). + +### c. Warm-pause and resume re-preparation + +The pause-for-reuse flow is: pool evicts (TTL/capacity/shutdown-idle) → `destroy(reason)` → +disposition `stop` → `pauseSandbox` → sandbox parked warm. The NEXT turn takes the cold path +(`coldAndPark` → `acquireEnvironment`), which reads the stored sandbox pointer and RECONNECTS the +paused sandbox (environment.ts:631-689, `sandbox-reconnect.ts`) — and then runs the same +preparation as a fresh acquire. So **add-on-start covers the resume by construction**, with one +ordering requirement: under the durable-home layout the Daytona auth write must move from its +current pre-mount position (environment.ts:739, fine for the in-VM home) to the post-mount position +the local write already occupies (environment.ts:876-885, "write AFTER the durable cwd mount — +doing it before would be shadowed"), and target `/.codex/auth.json` through the sandbox FS +API. The write must also become overwrite-always (the M5 Daytona writer already is; the local +`writeCodexManagedAuthFile` is create-if-absent and would need to refresh a stale key, +`codex-assets.ts`). One residual mismatch to close in implementation: delete-on-destroy + +create-only-if-absent would otherwise ping-pong `authFilePath` bookkeeping — under add/remove the +runner owns the file unconditionally, so delete-only-if-created (designed to protect a +pre-existing operator login) is moot for the managed cwd home. + +### d. Severity framing + +- **Under #5277 placeholders**: the durable file would hold `dtn_…placeholder…` — a value that is + only meaningful to that sandbox's egress proxy. A crash-window leak is cosmetic (a worthless + string in the customer's own workspace store). The add/remove lifecycle then buys tidiness, not + security. +- **Under today's real-key mode**: the durable file holds the REAL provider key in S3. The + crash-window leak is a live credential at rest in the conversation workspace, readable by + anything that later mounts the session cwd (including the user's own future runs listing + `.codex/`), for an unbounded time absent #5278. Note the intra-run exposure is identical in every + layout — codex itself, and therefore the agent, can always read its own credential while running + (P3's opaque pass-through is the same file/env value); the layouts differ only in what persists + AFTER the run. + +### Empirical resume fact (re-confirmed from P8, not re-run) + +Durable home + in-VM sqlite ⇒ durable native resume by construction: P8-combo +(`transcripts/p8-combo.jsonl`) already proved the exact shape — daemon destroyed, NEW daemon, +preserved home, **fresh empty `CODEX_SQLITE_HOME`** → `session/load` returned the SAME agent +session id and the codeword was retained. The resume dependency is exclusively the plain-file +portion of the home (`sessions/` rollouts + config/`installation_id`), all of which live on the +durable mount in the proposed layout; nothing else in-VM is consulted (the in-VM side holds only +the redirected SQLite, which P8-combo supplied fresh). Residual, unchanged from D-002's amendment: +these probes ran on local dirs — rollout jsonl appends on REAL geesefs (same write class as +Claude's mounted transcripts) and codex's `.tmp/` git activity on geesefs remain the two +validation items for the first durable-mount QA. + +--- + +## Recommendation — three layouts for Daytona managed mode + +| Layout | Native resume durable? | Key at rest in S3? | Crash window? | Moving parts | +|---|---|---|---|---| +| 1.

Durable home + file-free auth (`env_key` custom provider) | **yes** | **never (no file exists)** | none for credentials | config.toml gains 4 secretless lines; drop both auth writers + the backstop | + +- **Layout 3 wins and should be the ruling.** It is the only option that delivers BOTH halves of + Mahmoud's direction — durable native resume AND no key file ever — and it deletes machinery + instead of adding it (no auth writers, no symlink-vs-file split for managed mode, no teardown + backstop, no #5278 dependency for credentials). It composes best with #5277 (request-time env + read = placeholder lands exactly where the design puts it) and removes the ws-upgrade caveat for + the egress proxy. What would defeat it: a productization blocker not seen in the probes — the + known checks to run when implementing are a warm-reuse turn, a native resume after daemon + replacement under the custom provider (expected fine: `getResumeModelProvider()` reads the + config's `model_provider`), and the release-gate X1 journeys. The probes covered session + creation, real-API completion, usage accounting, model selection, and header byte-exactness. +- **Layout 2 is the fallback**, acceptable only with eyes open: an irreducible real-key crash + window until the #5278 plan ships a sweeper, plus the ordering fixes in (a)/(c). It would win + only if layout 3 hit a hard blocker AND durable resume stayed non-negotiable. +- **Layout 1 wins nothing long-term**; it is the smallest-safe stopgap already on the branch and + survives only until the layout-3 change lands. Its "no codex durable resume exists today to + lose" justification is exactly the crutch-shaped reasoning Mahmoud rejected. + +Also recommended regardless of layout: apply the same `env_key` mechanism to LOCAL managed codex +(one code path for both providers, and it retires the pre-existing local-durable backstop-ordering +gap found in (a) by removing the file the backstop was for).

These probes +supply the facts for the new layout decision. + +### P8a — a supported state redirect exists + +**Verdict: YES.** Codex 0.145 can move its SQLite state out of CODEX_HOME through a dedicated, +supported knob; the journal mode itself is hardcoded WAL. + +- Env var: `CODEX_SQLITE_HOME` (`codex-rs/state/src/lib.rs:93`, + `pub const SQLITE_HOME_ENV: &str = "CODEX_SQLITE_HOME";`), resolved in + `codex-rs/core/src/config/mod.rs` `resolve_sqlite_home_env` (relative values resolve against + the session cwd) and consumed as + `sqlite_home = cfg.sqlite_home ∥ $CODEX_SQLITE_HOME ∥ codex_home` (`mod.rs:3756-3761`). +- Config key: `sqlite_home` (the `Config` struct field documents it: "Directory where Codex + stores the SQLite state DB", `mod.rs:~893`); `log_dir` similarly moves logs (default + `$CODEX_HOME/log`). +- **Empirically verified on the daemon path** (`transcripts/p8-combo.jsonl`, `phase1-files`): + with `CODEX_SQLITE_HOME` set, ALL FOUR SQLite families (`state_5`, `goals_1`, `logs_2`, + `memories_1`, each with `-wal`/`-shm`) land in the redirect dir; `CODEX_HOME` retains only + plain files: `auth.json`, `config.toml`, `installation_id`, `sessions/` (thread rollouts, + jsonl), `shell_snapshots/`, `skills/`, `.tmp/`. +- WAL is hardcoded for every writable codex DB: + `codex-rs/state/src/sqlite.rs:36-49` `open_read_write_pool` sets + `.journal_mode(SqliteJournalMode::Wal)` unconditionally. Hence P8d below. + +### P8b — resume after daemon death needs the home, but only its plain files + +**Verdict: native resume DOES depend on CODEX_HOME content — a per-run ephemeral home silently +loses multi-turn context after daemon eviction. But the dependency is the `sessions/` rollout +files, NOT the SQLite: with the home preserved and a FRESH sqlite dir, native resume works.** + +Method (`scripts/p8-resume.mjs`, `scripts/p8-combo.mjs`): teach a session a codeword, destroy +the daemon, start a NEW daemon, seed the persist driver with the synthetic record exactly as the +runner does (`environment.ts` `persist.updateSession` + `resumeSession(localSessionId)`, which +drives the repo patch's `session/load` path in +`patches/sandbox-agent@0.4.2.patch`), then ask for the codeword. "Native load" = the resumed +`agentSessionId` equals the original (the patch falls back to `createRemoteSession` — a fresh +thread — when `session/load` fails, and the runner then flags `loadedFromContinuity=false` and +degrades to cold prompt-replay). + +| Phase | CODEX_HOME | sqlite dir | Native load | Codeword retained | Transcript | +|---|---|---|---|---|---| +| resume-1 | same, preserved | in home (default) | **yes** (same id) | **yes** (`FLAMINGO-42`) | `p8-resume.jsonl` phase2 | +| resume-2 | **fresh** (auth.json+config only) | in home (default) | **no** (new id, silent fallback) | **no** ("I don't know") | `p8-resume.jsonl` phase3 | +| combo | same, preserved | **fresh empty** `CODEX_SQLITE_HOME` | **yes** (same id) | **yes** (`OCELOT-77`) | `p8-combo.jsonl` phase2 | + +So the resume-critical state is exactly the geesefs-SAFE portion of the home (append-only jsonl +rollouts), and the geesefs-LETHAL portion (SQLite WAL) is exactly what the supported redirect +moves off. Note also the failure mode of an ephemeral home: no error — `session/load` falls back +silently and the model just doesn't know; only the runner's own cold-replay machinery would +paper over it (that is the existing non-native-continuity path, with its token cost and +history-fidelity limits). + +### P8c — Claude parity (code reading) + +Claude's equivalent state never sits on the geesefs cwd: + +- **Local durable runs**: Claude's config dir is the runner container's OWN disk — + `mount.ts:718`: "Local runs call none of this: `~/.claude` there is the runner container's own + disk"; the daemon only inherits `CLAUDE_CONFIG_DIR` when the operator sets one + (`daemon.ts:265-268`). Transcripts survive daemon eviction for the container's lifetime. +- **Daytona runs**: only `~/.claude/projects` — the session transcripts, plain jsonl — is + geesefs-mounted per session, "explicitly NOT `~/.claude` whole" + (`mount.ts:161-172 harnessSessionMounts`). +- Claude's native resume (`session/load` with `_meta.claudeCode.options.resume`, patch + `buildLoadSessionParams`) reads those transcript files. So Claude already relies on + jsonl-append files on geesefs (Daytona path) — the same write class as codex's `sessions/` + rollouts — and keeps its SQLite-free state off the mount. + +Parity conclusion: a per-run ephemeral codex home would be a **regression** vs Claude (Claude +keeps native resume across daemon eviction on both paths). A cwd home with the sqlite redirected +off-mount is parity-or-better (codex's resume files would be durable even across container +restarts, which local Claude's are not). + +### P8d — WAL off on geesefs + +Skipped, per the P8a finding: `open_read_write_pool` hardcodes `SqliteJournalMode::Wal` +(`state/src/sqlite.rs:40`); codex exposes no journal-mode knob, so there is nothing supported to +test. + +### Recommendation + +The facts support **keeping `CODEX_HOME = /.codex` on the durable mount and adding +`CODEX_SQLITE_HOME = ` to the codex daemon env** (m1 Option 2, now +proven): it removes exactly the wedging files from geesefs (P8a, all four DB families verified +moved), preserves native `session/load` resume across daemon eviction because resume rides the +rollouts that stay on the durable home (P8b combo), keeps the M3 `config.toml`-via-`harnessFiles` +delivery and the auth.json-on-cwd flow unchanged, and is parity-or-better with Claude (P8c). The +ephemeral-home alternative (m1 Option 1) silently breaks native multi-turn continuity after every +daemon eviction (P8b resume-2) — worse than Claude parity — and should only be a stopgap if +something else on the home turns out to wedge geesefs. Two validation items remain for the real +mount (these probes ran on local dirs): (1) confirm codex's `sessions/` jsonl appends behave on +geesefs — expected safe, it is the same write class Claude's mounted transcripts already use; +(2) watch `CODEX_HOME/.tmp/` and `skills/` — codex performed a git clone under `.tmp/plugins-*` +during session start, and git on geesefs is untested; if it misbehaves, `.tmp` may need its own +off-mount redirect (no supported knob seen — worth checking `codex-rs` for a tmp-dir override +before inventing one). + +--- + +## Surprises worth escalating + +1. **The adapter, not codex config, owns the sandbox/approval axis** (P2). `sandbox_mode` in + `config.toml`/`CODEX_CONFIG` is effectively dead on the daemon path; the ACP `mode` option is + the real switch and it couples full access with approval-never. This invalidates D-003 as + written and needs a decision (workspace-write + escalation-prompt HITL vs no-HITL full access). +2. **The d3b poison combo**: `sandbox_mode` inside CODEX_CONFIG next to `approval_policy` + silently killed all gates. CODEX_CONFIG payloads must be curated key-by-key, never passed + through from anything user-shaped. +3. **Codex speaks WebSockets first** (P3) — the egress proxy must handle (or fast-reject) the + upgrade request, which carries the same Authorization header. +4. **`openai_base_url` is project-local-denylisted upstream** (P3) — a workspace repo cannot + redirect credentials, which retires the credential half of first-spike risk 1. +5. **The auto-login writes whatever it is given** (P3) — good for placeholders, but it means a + typo'd real key is persisted silently too; failures only surface as 401s at run time. +6. **`agent-full-access` suppresses even explicit per-tool MCP "prompt" config** (P6) — the + full-access mode is a total gate blackout, not just a shell-approval policy. Any + HITL-for-tools posture must be enforced runner-side (e.g. in the tool-MCP gateway), not via + codex config. +7. **Enabling codex's inner sandbox locally costs `SYS_ADMIN` + unconfined seccomp/AppArmor on + the runner container** (P7) — a weaker outer boundary to gain an inner one, and it does not + transfer to Daytona. If declined, the local and cloud gate textures at least stay identical. + +## Transcript index (this round) + +| File | Scenario | +|---|---| +| `p1-two-sessions.jsonl` | one daemon, three sessions, CODEX_CONFIG fixed at daemon start; per-session env override attempt is a dead letter | +| `d1…d5-*.jsonl` | approval matrix, `danger-full-access` in `config.toml` (proves file `sandbox_mode` is overridden by the adapter) | +| `d1b…d5b-*.jsonl` | same matrix, `danger-full-access` via CODEX_CONFIG (proves CODEX_CONFIG `sandbox_mode` is also overridden; d3b = poison combo) | +| `e1…e4-fullaccess-*.jsonl` | real full access via `setConfigOption("mode","agent-full-access")`: zero gates everywhere, untrusted not restorable | +| `p3a/p3b-*.jsonl` | placeholder key against the real API (opaque pass-through, 401 echo, unvalidated auto-login write) | +| `p3a2/p3b2-baseurl.jsonl` + `p3-listener-capture.jsonl` | placeholder key against the local listener via `openai_base_url`: byte-exact Bearer header, `/responses` endpoint, ws-upgrade-then-POST transport | +| `f1…f3-fullaccess-mcp-*.jsonl` | MCP `prompt`/per-tool-`prompt`/`writes` approval config under `agent-full-access`: zero gates | +| `f1c-agentmode-mcp-prompt.jsonl` | control: same `prompt` config under default `agent` mode gates (proves the config is honored when the mode allows asking) | +| `p7-bwrap-matrix.log` | codex `sandbox` bwrap init matrix: host + 8 docker configs on the runner image, plus the enforcement check (produced by `scripts/p7-bwrap-matrix.sh`) | +| `p8-resume.jsonl` | resume after daemon death: same home = native load + codeword retained; fresh home = silent fallback, context lost (`scripts/p8-resume.mjs`) | +| `p8-combo.jsonl` | `CODEX_SQLITE_HOME` redirect: all sqlite moved off home (file inventory), and native resume retains context with a FRESH sqlite dir (`scripts/p8-combo.mjs`) | diff --git a/docs/design/codex-harness/spike/findings.md b/docs/design/codex-harness/spike/findings.md new file mode 100644 index 0000000000..c4cc09e604 --- /dev/null +++ b/docs/design/codex-harness/spike/findings.md @@ -0,0 +1,235 @@ +# Codex harness spike — empirical findings + +Date: 2026-07-24.

The + frame carries a top-level marker `"_meta": {"is_mcp_tool_approval": true}`. Note the naming convention + is **`mcp..` with dots**, not Claude's `mcp____` — `bareToolName`/ + `serverPermissionFor` will not match without a codex mapping. +- **Option ids differ per gate type**: exec = `allow_once / allow_always / accept_execpolicy_amendment / + reject_once`; MCP = `allow_once / allow_session / allow_always / decline`. The SDK maps + `reply: "always"` to the FIRST `allow_always`-kind option (verified in `permissionReplyToResponse` in + the SDK bundle) — for exec that's session-scoped "Allow for Session" (good: never the execpolicy + amendment), for MCP it's `allow_session` (also session-scoped, never the persistent "Don't Ask + Again"). `rawRespondPermission` exists if the runner ever wants to pick a specific optionId. + +--- + +## Q2 — Config: per-session config.toml, CODEX_HOME, env passthrough + +**Verdict: WORKS.** A throwaway `CODEX_HOME` per session is fully viable, and env vars pass through the +whole chain untouched. + +- **Env passthrough**: env passed to `local({ env })` reaches the daemon (`{...process.env, ...env}`), + which spawns codex-acp with its own env, which spawns `codex app-server` with inherited env. Proven + end-to-end: `CODEX_HOME` pointing at a throwaway dir was honored in every scenario (auth.json read + from there — `s2`; config.toml policy applied — `s4…s7`; codex wrote its state sqlite files there). +- **config.toml location**: `$CODEX_HOME/config.toml` is the primary file. **Codex 0.145 ALSO reads + project-level config from the workspace** — both `/.codex/config.toml` and bare + `/config.toml` were honored (`s12b`, `s12c` vs control `s12d`): a project file with + `approval_policy = "untrusted"` re-enabled gates that the global `never` had disabled.

See risks. +- **Auth/config separation**: yes — config can come from `CODEX_HOME/config.toml` while auth comes from + the `OPENAI_API_KEY` env var alone, IF the adapter is told to auto-login (see Q4a: `DEFAULT_AUTH_REQUEST`). + Without that, an `auth.json` must sit in `CODEX_HOME`. +- **Two extra per-session config channels** (adapter env vars read by codex-acp 1.1.7, all passthrough + from the daemon env): `CODEX_CONFIG` — a JSON object merged into the thread config on every + `session/new` (proven: `CODEX_CONFIG='{"approval_policy":"untrusted"}'` overrode the file's `never`, + `s14-codexconfig-env.jsonl`); `CODEX_PATH` — path to the codex binary to spawn; `MODEL_PROVIDER`; + `DEFAULT_AUTH_REQUEST` (Q4).

The spike's stdio echo server was spawned, listed, and called (`s9-mcp-acp.jsonl`; the MCP + server's own request log confirms `initialize`/`tools/list`/`tools/call`). `http`/`sse` typed variants + are also in the adapter's schema — the runner's HTTP `agenta-tools` entry should work as-is. +- **(b) `config.toml` `[mcp_servers.]`**: identical behavior (`s10-mcp-config.jsonl`). +- **Event stream shape**: an MCP call appears as a normal ACP `tool_call` update: + `sessionUpdate: "tool_call"`, `kind: "execute"`, `title: "mcp.spike.spike_echo"`, + `rawInput: {"server": "spike", "tool": "spike_echo", "arguments": {…}}`, then a `tool_call_update` + with `rawOutput: {"error": null, "result": {"content": [{"type": "text", "text": "SPIKE_ECHO_RESULT:hello-mcp"}]}}` + and `status: "completed"`. +- **Approval behavior**: MCP tool calls gated under BOTH `untrusted` (`s9`) and `on-request` (`s10`) + policies, with the MCP-flavored option set (`_meta.is_mcp_tool_approval: true`; options + allow_once/allow_session/allow_always/decline). +- **F-046 (per-tool pre-allow): WORKS via config.** `[mcp_servers.] default_tools_approval_mode = + "approve"` made the tool run with ZERO permission requests even under `approval_policy = "untrusted"` + (`s13-mcp-preallow.jsonl`). The enum is `auto | prompt | writes | approve` (parse error message from a + direct-CLI probe). A per-tool override shape `[mcp_servers..tools.] approval_mode = + "approve"` parses cleanly (direct-CLI parse probe only — behavior not exercised through the daemon). + There are also `enabled_tools` / `disabled_tools` lists per server (binary strings; not exercised). + So codex has a direct analog of Claude's per-tool allow rules, delivered through config instead of + settings.json. + +--- + +## Q4 — Auth modes + +**Verdict: all three forms work; env-var-alone needs one adapter env var.** + +- **(a1) `OPENAI_API_KEY` env var ALONE: does NOT work by default.** `session/new` fails with ACP error + -32000 `Authentication required` (`s1-auth-env-only.jsonl`). codex-acp checks codex's account status + and only auto-authenticates when `DEFAULT_AUTH_REQUEST` is set. +- **(a2) env var + `DEFAULT_AUTH_REQUEST='{"methodId":"api-key"}'` in the daemon env: WORKS** + (`s3-defaultauth.jsonl`). The adapter runs an api-key login against env `CODEX_API_KEY` → + `OPENAI_API_KEY` (that precedence, from the bundle source) and codex then **writes** + `auth.json = {"auth_mode": "apikey", "OPENAI_API_KEY": "sk-…"}` into `CODEX_HOME`. +- **(a3) pre-seeded `auth.json` `{"OPENAI_API_KEY": "sk-…"}` in `CODEX_HOME`: WORKS** with no env key at + all (`s2-auth-authjson-apikey.jsonl`). This is the minimal, most predictable API-key setup for the + runner: write config.toml + auth.json into a throwaway CODEX_HOME and point the session at it. +- **(b) Subscription OAuth: WORKS.** Copied `~/.codex/auth.json` (shape: + `{"OPENAI_API_KEY": null, "tokens": {"id_token", "access_token", "refresh_token", "account_id"}, + "last_refresh"}`) into a temp CODEX_HOME; the daemon-path session authenticated and completed a prompt + (`s11-oauth.jsonl`). **No refresh-write was observed** (md5 + mtime of the copied auth.json unchanged + after the run; tokens were 6 days old and still accepted). Refresh-on-expiry against a copy remains + unproven — if/when codex refreshes, it will write to the copy in the temp CODEX_HOME, and whether the + ChatGPT backend invalidates the original login's refresh token at that point was NOT tested. The live + `~/.codex` was never opened for writing. + +--- + +## Surprises and risks + +1. **Workspace files can change codex policy.** Codex 0.145 reads `/.codex/config.toml` AND bare + `/config.toml` as config layers. Observed to tighten only (loosening was ignored in `s12e`), but + this is undocumented-behavior territory: a repo checked out into the workspace can alter gating + behavior (e.g., force approvals the runner didn't plan for, add MCP servers?, change the model?). + Which keys the project layer may set was not mapped — worth a follow-up before GA. A workspace + containing a stray `config.toml` (like this repo's own examples) silently becomes codex config. +2. **The adapter is `@agentclientprotocol/codex-acp`, not `@zed-industries/codex-acp`**, fetched at + daemon-install time from the ACP registry CDN with a **floating `^1.1.7` npm range** and a bundled + codex pin inside it. The runner does not control this version today: first-run installs get whatever + the registry serves (supply-chain + drift risk; the Claude adapter is pinned in package.json by + contrast). `CODEX_PATH` exists to force a specific codex binary; there is no equivalent pin for the + adapter itself short of pre-installing the launcher dir. +3. **`gpt-5.1-codex*` model ids are rejected as deprecated** by the backend even though + `/v1/models` still lists them. The session's advertised models are gpt-5.6-sol/terra/luna, gpt-5.5, + gpt-5.2 (`s2` session-state). Cheapest for probes: `gpt-5.6-luna`. +4. **Codex's bubblewrap sandbox does not fully initialize on this host** (`bwrap: loopback: Failed + RTM_NEWADDR: Operation not permitted` — likely because the spike ran in an unprivileged container-ish + context). Approval flows still worked, but "run inside sandbox" attempts fail, which changes the + texture of `untrusted` runs (codex asks to run OUTSIDE the sandbox "because the sandbox failed to + initialize"). Inside the runner's Daytona/Docker sandboxes the same nested-sandbox problem is likely; + codex has `sandbox_mode` config and the daemon runs in a container, so `danger-full-access` + + container isolation may be the practical setting (same trade-off the Claude harness makes). +5. **codex-acp auto-trusts the session cwd** (`projects..trust_level = "trusted"` injected into + every thread config), so codex's own first-run trust prompt never appears on the daemon path. +6. **`approval_policy = "never"` + workspace-write is a real "no gates" mode** (`s7`): nothing pauses, + the sandbox is the only enforcement.
