Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Verification Before Completion ## Overview **Core principle:** Evidence before claims, always. **Violating the letter of this rule is violating the spirit of this rule.** ## The Iron Law ``` NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE ``` If you haven't run the verification command in this message, you cannot claim it passes. ## The Gate Function ``` BEFORE claiming any status or expressing satisfaction: 1. IDENTIFY: What command proves this claim? 2. RUN: Execute the FULL command (fresh, complete) 3. READ: Full output, check exit code, count failures 4. VERIFY: Does output confirm the claim? - If NO: State actual status with evidence - If YES: State claim WITH evidence 5. ONLY THEN: Make the claim Skip any step = lying, not verifying ``` ## Common Failures | Claim | Requires | Not Sufficient | |-------|----------|----------------| | Tests pass | Test command output: 0 failures | Previous run, "should pass" | | Linter clean | Linter output: 0 errors | Partial check, extrapolation | | Build succeeds | Build command: exit 0 | Linter passing, logs look good | | Bug fixed | Test original symptom: passes | Code changed, assumed fixed | | Regression test works | Red-green

How do I install it?

Where does this skill come from?
From guanyang/open-agent-hub, a repository with 948 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
