SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? AI agents and developers often claim work is complete, fixed, or passing without actually running the verification command, leading to broken builds, shipped bugs, and lost trust. This Skill enforces an evidence-first discipline so no completion claim is made without fresh verification output. ## Core Features & Use Cases - The Iron Law gate: Blocks any completion, success, or satisfaction claim until a verification command has been run and its output read in the current session. - Claim-to-evidence mapping: Defines what proof each claim requires, such as test output showing zero failures, build exit code 0, or a RunVerification gameplay probe pressing input and reading state back. - Rationalization prevention: Lists common excuses ("should work", "linter passed", "agent said success") and the correct evidence-based response to each. - Use Case: Before committing a bug fix, the agent runs the test suite, confirms 0 failures in the output, and only then reports the fix as verified, instead of assuming the code change worked. ## Quick Start Before you claim any task is done, fixed, or passing, run the full verification command, read its complete output and exit code, and only then state the result with that evidence.

FAQPage Schema
How do I verify work is complete before claiming it is done?

Identify the command that proves the claim, run it fresh and in full, read the complete output and exit code, and only then state the result with that evidence. Skipping any step means the claim is unverified.

How to verify a bug fix actually works?

Reproduce the original symptom with a test or probe and confirm it now passes. A code change alone is not evidence; for gameplay behavior, use a RunVerification probe that presses input and reads state back.

Is a passing linter enough to claim the build succeeds?

No. A linter does not check compilation, so a clean lint run is not evidence of a successful build. You must run the actual build command and confirm it exits with code 0.

How do I verify a regression test really catches the bug?

Use a red-green cycle: write the test, confirm it passes with the fix, revert the fix and confirm the test fails, then restore the fix and confirm it passes again. A test that never fails proves nothing.

Can I trust an agent's success report without checking?

No. Agent success reports must be independently verified by inspecting the VCS diff and confirming the changes exist and work. Trusting a report without evidence is a common failure mode.
