Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses.
Skill Claude CodeCodex
Use when invalid data causes failures deep in execution, requiring validation at multiple system layers - validates at every layer data passes through to make bugs structurally impossible.
Skill Claude CodeCodex
MANDATORY when GOAL.md mentions deploying, shipping, releasing, or publishing built artifacts to any environment - reads deployment instructions from the .deploy/ directory, enforces pre-deployment verification, artifact integrity checks, deployment execution safety, post-deployment validation, and rollback planning…
