Build test

Spec §20.2 / §22.4: the "subjective critique-theater panel" is not enough on its own — a code-migration / tune-collab run must prove the build still passes. This atom shells out to the project's declared test commands and emits structured signals the devloop's until evaluator reads.

Inputs

• The active target stack (recorded in code/index.json + plan.md's targetStack block).
• The user's optional override (od plugin run --input testCommand='pnpm test').

Default commands by framework

framework	typecheck	test
next	pnpm typecheck	pnpm test
vite	pnpm typecheck	pnpm test
remix	pnpm typecheck	pnpm test
custom	(read from package.json.scripts)	(read from package.json.scripts)

Output

project-cwd/
└── critique/
    ├── build-test.json   # { build: 'passing' | 'failing', tests: 'passing' | 'failing' | 'skipped', durationMs, commandsRun: [...], failures: [...] }
    └── build-test.log    # raw stdout / stderr (truncated to the runner's logBudgetBytes limit, default 1 MiB)

The atom emits two signals the devloop reads:

• build.passing: boolean — the typecheck command exited 0.
• tests.passing: boolean — the test command exited 0.

Plus the legacy critique.score so existing pipelines that read the score keep working: 5 when both pass, 3 when only build passes, 1 when both fail.

Convergence

Pipelines wire the atom into a devloop:

{
  "id": "verify",
  "atoms": ["patch-edit", "build-test"],
  "repeat": true,
  "until": "(build.passing && tests.passing) || iterations >= 8"
}

Anti-patterns the prompt fragment forbids

• Running tests on a partially-edited working tree (the atom always runs after patch-edit, and only when plan.steps's current step is in completed state).
• Suppressing test failures by changing test files; that violates the rewrite-plan ownership rule.
• Setting tests: 'skipped' without a non-empty reason field.

Status

Implemented by the daemon runner in apps/daemon/src/plugins/atoms/build-test.ts. It executes the configured build and test commands, bounds runtime and captured logs, and persists the report and log outputs above.
