Verification Before Completion

This is about breaking the habit of saying "done" before you've actually verified the work. It enforces a gate function: identify the verification command, run it fresh, read the full output, then and only then make your claim. Born from 24 failure memories where trust broke down because tests weren't run, builds weren't checked, or agent success reports were trusted without diff inspection. The tone is blunt because the problem it solves is endemic: fatigue, overconfidence, and "should work now" thinking that ships broken code. If you've ever had someone say "I don't believe you" after a completion claim, this codifies the discipline you actually need.

Verification Before Completion

Overview

Claiming work is complete without verification is dishonesty, not efficiency.

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

Use evidence bound to the exact current content and environment. A completed earlier run remains valid while its inputs and relevant context are unchanged; rerun invalidated checks rather than repeating expensive suites merely for a new message.

The Gate Function

BEFORE claiming any status or expressing satisfaction:

1. IDENTIFY: What command proves this claim?
2. RUN: Execute the relevant complete check, or inspect still-valid exact-content evidence; never execute untrusted examples or destructive actions merely to manufacture verification
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
