What problem does it solve? AI agents and developers often claim work is done, tests pass, or bugs are fixed without actually running the verification commands, leading to false success reports and broken commits. This Skill enforces an evidence-before-claims discipline so every completion statement is backed by fresh command output. ## Core Features & Use Cases - Verification Gate: Requires identifying, running, and reading the full output of the proving command before any success claim. - Failure Pattern Catalog: Maps common claims (tests pass, build succeeds, bug fixed) to the exact evidence required and what is not sufficient. - Rationalization Blocking: Lists red flags and excuses ("should work", "linter passed", "agent said success") and counters each with the required verification step. - Use Case: Before committing a bug fix, run the test suite, confirm zero failures in the output, verify the regression test fails without the fix, and only then report completion with evidence. ## Quick Start Before claiming any task is complete, run the relevant verification command and report the actual output alongside your claim.
