What problem does it solve? AI agents and developers often claim work is complete, tests pass, or bugs are fixed without actually running the verification commands, leading to broken builds, shipped defects, and lost trust. This Skill enforces an evidence-first discipline so no success claim is made without fresh command output. ## Core Features & Use Cases - Verification Gate: Defines a mandatory five-step gate (identify, run, read, verify, claim) that must be completed before any completion statement. - Failure Pattern Catalog: Maps common claims (tests pass, build succeeds, bug fixed, agent completed) to the exact evidence required and what does not count as proof. - Rationalization Blocking: Lists red-flag phrases and excuses ("should work", "linter passed", "agent said success") and counters each with the required verification action. - Use Case: Before committing a bug fix, the agent runs the test suite, confirms zero failures in the output, verifies the regression test fails without the fix, and only then reports completion with the evidence attached. ## Quick Start Ask the agent to verify the fix by running the full test suite and only claim completion after confirming the output shows zero failures.
