| name: Auto-assign Reviewer | |
| # Repo-level reviewer assignment: assign EXACTLY 1 reviewer to FORK PRs authored | |
| # by a non-maintainer, preferring the owners of the area(s) the PR touches. No org | |
| # team required. Ownership is read from .github/areas.json at runtime -- a custom, | |
| # non-magic path (NOT .github/CODEOWNERS), so GitHub's native CODEOWNERS | |
| # auto-request never fires and this action is the sole assigner. Non-fork / | |
| # collaborator / maintainer PRs are left alone. | |
| # It also keeps the PR reviewer and any linked ("closes #N") issue's assignee in | |
| # sync: a maintainer already assigned to a linked issue is adopted as the | |
| # reviewer, and the chosen reviewer is assigned onto any still-unassigned linked | |
| # issue. See auto-assign-reviewer.js. | |
| # | |
| # Reviewer choice among an area's owners: an optional LLM step ranks the owners by | |
| # area fit (from the .github/areas.json definitions + the changed-file list) and | |
| # the script prefers the top-ranked owner, breaking ties by open-review load. The | |
| # LLM is advisory and allowlist-bounded -- it can only REORDER an area's owners, | |
| # never add anyone -- and if it is unavailable (no creds) or fails, the script | |
| # falls back to the pure load-balanced pick. Same secrets + gateway as issue | |
| # triage; only the changed-file PATH list (never diff contents or PR prose) is | |
| # sent to the model. | |
| # | |
| # pull_request_target so it can manage reviewers on fork PRs (a fork's | |
| # pull_request token is read-only). Safe: it checks out only the trusted default | |
| # branch (.github), never PR head, and runs no PR code -- it reads | |
| # .github/areas.json + .github/MAINTAINER + the changed-file list, queries the | |
| # PR's linked issues, and calls the reviewers / assignees API. The offline unit | |
| # test (auto-assign-reviewer.test.js) covers the logic. | |
| on: | |
| pull_request_target: | |
| # `edited` catches a `closes #N` link added after open (stub body, then | |
| # filled in): on that event the script is promote-only (adopt a linked-issue | |
| # assignee if one now exists, else leave the current pick untouched). Still | |
| # checks out only the trusted default branch, never PR head -- no PR code runs. | |
