Verification Before Completion

Core principle: Evidence before claims, always.

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

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
• About to commit/push/PR without verification
• Trusting agent success reports
• Relying on partial verification
• Thinking "just this once"

Key Patterns

Tests:

[Run test command] [See: 34/34 pass] "All tests pass"
NOT: "Should pass now" / "Looks correct"

Build:

[Run build] [See: exit 0] "Build passes"
NOT: "Linter passed" (linter doesn't check compilation)

Requirements:

Re-read plan -> Create checklist -> Verify each -> Report gaps or completion
NOT: "Tests pass, phase complete"

Agent delegation:

Agent reports success -> Check VCS diff -> Verify changes -> Report actual state
NOT: 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
