Verification Before Completion

Overview

Any "completed" statement MUST be supported by evidence. This skill provides a pre-completion Gate Function, ensuring results are reproducible, traceable, and deliverable.

Ironclad Rules

• No evidence = no completion claim.
• Evidence MUST be reproducible by others; verbal descriptions are NOT accepted.
• If tests/checks fail, the status MUST revert to in-progress.

When to Use

• Tasks are preparing to enter /ship.
• Before submitting PRs or handing off work.
• After completing high-risk changes (data, permissions, core flows).

Gate Function

1. Scope Gate: Confirm changes only cover the agreed scope.
2. Quality Gate: Execute required tests and static checks.
3. Evidence Gate: Compile reproducible evidence (commands, outputs, versions).
4. Risk Gate: Confirm rollback strategies and known risks.
5. Communication Gate: Output a completion summary (changes, validation, constraints).

Minimum Evidence Checklist

• At least one set of tests/checks directly related to this change.
• Specific execution commands and results (Success/Failure/Warning).
• If there are unfinished items, explicitly mark them with follow-up suggestions.

Common Mistakes

• Claiming "it should work" without any output evidence.
• Testing only the happy path, missing regressions or edge cases.
• Treating old test results as evidence for new changes.
