Verification Before Completion
Overview
Claiming work is complete without verification is dishonesty, not efficiency.
Core principle: Evidence before claims, always. This aligns directly with Axiom A1 (Verifiability) from the Factory .agentrules.
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.
Key Patterns
Tests:
✅ [Run test command] [See: 34/34 pass] "All tests pass"
❌ "Should pass now" / "Looks correct"
Build:
✅ [Run build] [See: exit 0] "Build passes"
❌ "Linter passed" (linter doesn't check compilation)
Agent delegation:
✅ Sub-agent reports success → Check VCS diff → Verify changes → Report actual state
❌ Trust sub-agent report completely
Why This Matters
As an Antigravity agent, you are governed by the Integrity & Guardian Axioms. Axiom A1 (Verifiability) mandates that evidence must precede assertions.
The Bottom Line
No shortcuts for verification.
Run the command. Read the output. THEN claim the result. This is non-negotiable before closing Plane tasks or marking workflow steps complete.
