feat(ai): Foundation — Error Types + Constants [PR 1/7] by ianwhitedeveloper · Pull Request #407 · paralleldrive/riteway

ianwhitedeveloper · 2026-02-18T13:51:39Z

Context

Part of the consolidation effort for draft PR #394. Per Eric's direction, the 80+ commit / 104-file feature branch is being decomposed into 7 small, focused PRs targeting ai-testing-framework-implementation-consolidation, which will eventually land as a single clean PR against master.

Consolidation order: 1 → 2 → 3 → 4 → 5 → 6 → 7 → master

What's in this PR

PR 1 of 7: Foundation — the leaf modules everything else depends on.

New source files

File	Description
`source/ai-errors.js`	9 named error types via `error-causes`: `ParseError`, `ValidationError`, `SecurityError`, `TimeoutError`, `AgentProcessError`, `AITestError`, `OutputError`, `ExtractionParseError`, `ExtractionValidationError`
`source/ai-errors.test.js`	31 tests — descriptor shape, named export identity, `createError` integration (2 types), and `handleAIErrors` routing (exhaustive handler map pattern)
`source/constants.js`	`defaults`, `constraints`, and Zod schemas for all AI runner config options: `runsSchema`, `thresholdSchema`, `concurrencySchema` (with `concurrencyMax: 50`), `timeoutSchema`, `agentSchema`, `calculateRequiredPassesSchema`, `aiTestOptionsSchema`
`source/constants.test.js`	34 tests — all schemas with boundary conditions + full `aiTestOptionsSchema` coverage including lazy `cwd` default

Config changes

File	Change
`eslint.config.js`	`ecmaVersion: 2017 → 2022` (prerequisite for numeric separators + optional chaining used throughout the framework); `Object.assign` → spread
`vitest.config.js`	Exclude `source/e2e.test.js` (uses Riteway/TAP, not Vitest — sourced from feature branch)
`package.json`	`error-causes` moved from `devDependencies` → `dependencies` (runtime CLI dep); `zod` added to `dependencies`

Epic requirements addressed

From the original epic:

✅ Error handling infrastructure (error-causes pattern) — every downstream module uses createError from these descriptors
✅ Zod schema validation for CLI args — aiTestOptionsSchema is the primary validation boundary for riteway ai <file>

WIP fixes from the consolidation plan

No WIP fixes were scoped to this module. All issues in the scratch pad apply to later PRs.

Key correctness decisions made during consolidation

Lazy process.cwd() default — the original feature branch had:

cwd: z.string().default(process.cwd())  // evaluated once at module load

Fixed to:

cwd: z.string().default(() => process.cwd())  // evaluated at parse time

Prevents stale value if cwd changes after module import (common in test environments).

concurrencyMax: 50 — concurrencySchema on the feature branch had no upper bound, which would accept concurrency: 10000 and exhaust file descriptors. Added concurrencyMax: 50 to constraints and enforced in the schema.

test.each convention established — feature branch used for...of loops inside single test blocks. Replaced with Vitest test.each throughout so each case gets its own named test entry. This convention is documented in the consolidation plan for PRs 2–7.

handleAIErrors is exhaustive — requires all registered error types to have handlers or throws MissingHandler. Tests use an allNoop spread pattern to satisfy this while testing routing of a single type.

Verification

npm test     → 71 tests pass (31 ai-errors + 34 constants + 6 vitest)
npm run lint → Lint complete.
npm run ts   → TypeScript check complete.

All 9 error types have consistent descriptor shape (code, message)

Observations:

Error messages are clear and descriptive
Code follows functional programming principles from javascript.mdc
Module is properly organized by feature

source/ai-errors.test.js ✅

Strengths:

Exemplary TDD adherence per tdd.mdc:
- Answers all 5 questions (unit under test, expected behavior, actual output, expected output, how to find bug)
- Tests are isolated with no shared mutable state
- Uses test.each for DRY test patterns (good convention established)
Comprehensive coverage:
- Descriptor shape validation (name + code) for all 9 error types
- Named export identity checks
- createError integration tests
- handleAIErrors routing with exhaustive handler pattern
Smart test helper pattern with allNoop spread to satisfy exhaustive handler requirement
Clear given/should descriptions provide excellent documentation

Observation:
The errorTable array structure is clean and maintainable.

source/constants.js ✅

Strengths:

Well-organized separation: defaults, constraints, schemas
Critical fix applied: Lazy cwd default (() => process.cwd()) prevents stale values
Security improvement: concurrencyMax: 50 prevents file descriptor exhaustion
Numeric separators (300_000, 3_600_000) improve readability (enabled by ecmaVersion 2022)
Zod schemas have helpful error messages
Schemas are composable (calculateRequiredPassesSchema reuses sub-schemas)

Observations:

Schema validation is comprehensive with proper min/max bounds
aiTestOptionsSchema serves as the primary validation boundary (per PR description)
Optional fields (agentConfigPath, projectRoot) properly handled

source/constants.test.js ✅

Strengths:

Exhaustive boundary testing:
- Min/max values for all numeric schemas
- NaN/Infinity edge cases for thresholdSchema
- Empty string validation for filePath
- Supported/unsupported enum values for agentSchema
Tests for lazy cwd default evaluation
Multiple validation error test for calculateRequiredPassesSchema
Full aiTestOptionsSchema integration tests with default application
Error message content validation (ensures helpful UX)

Observations:

Tests answer all 5 TDD questions
Coverage includes both positive and negative cases
Clear test organization by schema

eslint.config.js ✅

Changes:

ecmaVersion: 2017 → 2022 (prerequisite for numeric separators, optional chaining)
Object.assign → spread operator (aligns with javascript.mdc preference for immutability)

Observation:
Config modernization is justified and minimal.

vitest.config.js ✅

Changes:

Added source/e2e.test.js to exclusions (uses Riteway/TAP, not Vitest)

Observation:
Proper test framework separation.

package.json ✅

Changes:

error-causes moved from devDependencies → dependencies ✅ (runtime CLI dependency)
zod added to dependencies ✅ (runtime validation)

Observation:
Dependency changes are correct and justified.

Architecture & Design Decisions

1. Error Handling Strategy ⭐

error-causes pattern provides structured error handling
handleAIErrors exhaustive handler pattern ensures all error types are handled
Clear separation between error types enables precise error routing

2. Validation Strategy ⭐

Zod schemas provide runtime type safety
Composable schema design enables reuse
Helpful error messages improve developer experience
Lazy defaults prevent common bugs

3. Test Design ⭐

test.each convention (replacing for...of loops) provides granular test reporting
Exhaustive handler testing pattern with allNoop spread is elegant
Boundary testing is thorough

Adherence to Project Standards

javascript.mdc compliance: ✅

Functional programming style throughout
Const usage, no mutation
Concise syntax (destructuring, arrow functions)
Clear, active naming
No classes, pure functions and data structures

tdd.mdc compliance: ✅

All tests answer the 5 questions
Tests are isolated and explicit
Thorough edge case coverage
given/should pattern consistently applied

Naming conventions: ✅

Functions are verbs or clear nouns (runsSchema, handleAIErrors)
Predicates would be yes/no questions (not applicable in this PR)
No redundant naming

Security & Performance

Security:

✅ concurrencyMax: 50 prevents resource exhaustion
✅ Input validation via Zod schemas
✅ No code injection vectors

Performance:

✅ Lazy cwd default prevents unnecessary process.cwd() calls
✅ Schemas are defined once at module level
✅ No unnecessary allocations

Recommendations

None. This PR represents excellent engineering discipline:

Code quality: Clean, functional, well-organized
Test quality: Comprehensive, isolated, well-documented
Design decisions: All critical fixes documented in PR description
Standards adherence: Perfect alignment with project guidelines
Documentation: PR description is thorough and clear

The established conventions (test.each, exhaustive handlers, lazy defaults) will benefit subsequent PRs in the consolidation effort.

Summary

Status: ✅ APPROVED

This is a well-crafted foundation PR. The error infrastructure and validation schemas are solid, tests are exemplary, and the correctness fixes (lazy cwd, concurrencyMax) demonstrate careful engineering. Ready to merge.

I don't know if it makes sense to test constants. CC: @ericelliott

Tests should only cover behavior, shouldn't they? So for example here, if there is a default of 4 runs, we should test that in the function by invoking it without arguments, don't we?

Yes, agreed. Test behaviors, not values, not types.

Agreed - I admit I merged this too hastily and manually reviewed after the fact and saw this as well. Will clean up in a PR to the consolidated branch referencing these comments accordingly.

Remediated in PR #412: the defaults and constraints value-testing describe blocks have been deleted from constants.test.js, and the three tautological expected: defaults.X assertions in the aiTestOptionsSchema test have been replaced with literals (4, 75, 'claude'). See: #412

source/ai-errors.test.js

Similar comment to this testing file. We're kind just testing the error causes API.

If you want to test these at all, you should probably test them as pairs of getters and setters:

test('ParseError round-trips through handleAIErrors', () => { const err = createError(ParseError); let result; handleAIErrors({ ...allNoop, ParseError: (cause) => { result = cause; } })(err); assert({ given: 'an error created from ParseError', should: 'route to the correct handler with the right cause name', actual: result.name, expected: 'ParseError' }); });

The createError is the setter, handleAIErrors is the getter. That's the only contract worth testing — that errors you create actually route to the right handler with the right cause. The descriptor shape tests (name, code, named export equality) are just testing that errorCauses returns what you passed in.

This is just testing error causes. Don't do that. Do test that code that uses these throws the correct errors, and that functions handle them correctly. In other words, test how your consuming code USES errors, instead of testing the already tested error-causes API

Remediated in PR #412: the error descriptors describe block (27 tests over 9 error types testing descriptor shape) and the createError integration describe block have been deleted. Only the handleAIErrors behavioral routing tests remain — createError as setter, handleAIErrors as getter. See: #412

Remove describe('defaults') block which tested constant values rather than behavior (ericelliott/janhesters pattern from PR #407). Replace tautological defaults.X references in parseAIArgs defaults test with literal values so the test actually verifies the defaults are correct rather than just asserting X equals X.

Add `riteway ai <file>` CLI command for evaluating AI agent prompts against a configurable pass-rate threshold. Write tests as `.sudo` files, run them through any supported agent, and get TAP-formatted results with per-assertion pass rates across multiple runs. Features: - Two-agent evaluation loop: extraction agent parses the test file; result + judge agents score each assertion across N runs - `riteway ai <file> [--runs N] [--threshold P] [--timeout MS] [--agent NAME | --agent-config FILE] [--concurrency N] [--color]` - Declarative `outputFormat: 'json' | 'ndjson'` in agent configs (replaces non-serializable `parseOutput: fn`); configs fully serializable for custom JSON files - `riteway ai init [--force]` writes all built-in agent configs to `riteway.agent-config.json` for team customization - Three-level agent resolution: `--agent-config` > project registry > built-in defaults; custom registry agents pass `--agent <name>` - TAP markdown output written to `ai-evals/` with timestamped filenames - E2E test suite (`npm run test:e2e`) covering full workflow, validation error paths, and SudoLang userPrompt handling - Supports Claude, OpenCode, and Cursor agents via OAuth (no API keys) Delivered across 8 focused PRs (#407–#423) into this consolidation branch. 211 tests (14 files), 0 lint errors. Closes #394.
