# 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.
