build-test
Run the project's build / typecheck / lint / test commands and emit the build.passing + tests.passing signals devloop convergence reads.
Why this skill is useful
Adds a custom executable script for running build and test commands that integrates with the devloop, providing structured output not covered by standard practices.
What it needs
Requires pnpm installed locally. About 1k tokens when loaded. Last updated 2026-08-07. 84,236 stars on the source repository.
What this skill does
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 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: 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.
