spec-runner

Implement a spec-runner task end-to-end with the pi coding agent — write the code AND its tests, run the tests via bash until green, then emit the spec-runner completion marker. Use during the development stage of the dev→review→test loop.

Read-only code review for a spec-runner task with the pi coding agent — inspect the diff and changed files, report findings, and emit a pass/fail verdict WITHOUT editing any code. Use during the review-gate stage of the dev→review→test loop.

Strengthen a module's test suite with the pi coding agent — add missing edge-case, error-path and regression tests, then run them to confirm they pass. Use for a standalone test-hardening step (script or plugin) outside the main task gate.
