What problem does it solve? AI agents and developers often claim work is complete, tests pass, or bugs are fixed without actually running 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: A mandatory five-step gate (identify command, run it, read output, verify result, then claim) applied before any completion statement. - Failure Pattern Tables: Concrete mappings of common claims (tests pass, build succeeds, bug fixed) to the exact evidence required and what does not count as proof. - Rationalization Blocking: Red-flag phrases and excuse counters that stop shortcuts like "should work", "linter passed", or trusting agent success reports. - 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 state the fix is verified. ## Quick Start Before claiming any task is done, run the full verification command, read the complete output and exit code, and only then state the result with that evidence.
