# 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 cycle verified | Test passes once | | Agent completed | VCS diff shows changes | Agent reports "success" | | Requirements met | Line-by-line checklist | Tests passing |
Red Flags - STOP
- Using "should", "probably", "seems to"
- Expressing satisfaction before verification ("Great!", "Perfect!", "Done!", etc.)
- About to commit/push/PR without verification
- Trusting agent success reports
- Relying on partial verification
- Thinking "just this once"
- Tired and wanting work over
- **ANY wording implying success without having run verification**
Rationalization Prevention
| Excuse | Reality | |--------|---------| | "Should work now" | RUN the verification | | "I'm confident" | Confidence ≠ evidence | | "Just this once" | No exceptions | | "Linter passed" | Linter ≠ compiler | | "Agent said success" | Verify independently | | "I'm tired" | Exhaustion ≠ excuse | | "Partial check is enough" | Partial proves nothing | | "Different words so rule doesn't apply" | Spirit over letter |
Key Patterns
**Tests:** ``` ✅ [Run test command] [See: 34/34 pass] "All tests pass" ❌ "Should pass now" / "Looks correct" ```
**Regression tests (TDD Red-Green):** ``` ✅ Write → Run (pass) → Revert fix → Run (MUST FAIL) → Restore → Run (pass) ❌ "I've written a regression test" (without red-green verification) ```
**Build:** ``` ✅ [Run build] [See: exit 0] "Build passes" ❌ "Linter passed" (linter doesn't check compilation) ```
**Requirements:** ``` ✅ Re-read plan → Create checklist → Verify each → Report gaps or completion ❌ "Tests pass, phase complete" ```
**Agent delegation:** ``` ✅ Agent reports success → Check VCS diff → Verify changes → Report actual state ❌ Trust agent report ```
When To Apply
**ALWAYS before:** - ANY variation of success/completion claims - ANY expression of satisfaction - ANY positive statement about work state - Committing, PR creation, task completion - Moving to next task - Delegating to agents
**Rule applies to:** - Exact phrases - Paraphrases and synonyms - Implications of success - ANY communication suggesting completion/correctness
