Verification Before Completion

Overview

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

Core principle: Evidence before claims, always.

This rule serves shipping — it is not a ritual that outranks it. It governs one thing: claims that a verifiable result holds ("tests pass", "build succeeds", "bug fixed") — run the check before you assert it, and scale the check to the stakes (a one-line copy tweak is not a test-suite ceremony). Don't dodge it with synonyms; equally, don't inflate it into a tax on the word "done" or a reason to keep re-proving instead of shipping the working thing.

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"
• Claiming a specific result is proven ("tests pass", "it's fixed", "build's green") before running the check in this message — enthusiasm itself is fine; an unverified result claim is the flag
• 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 the check itself lies — content over shape

Running a verification is necessary but not sufficient: a check can exit clean and still prove nothing. These are the named ways a green check lies — the failure siblings behind "evidence before claims." (Deeper treatment of what you verify against: reference-first-verification.)

• Assert on CONTENT, never shape or count. Output that looks like success — a non-zero count, a clean exit, no error text — can carry failure as its content. Before trusting a check, ask what its output looks like when it fails: if failure and success are indistinguishable at a glance, the check proves nothing. ([1 lines] and No matches found both read as "a match" to a line-count.)
• Compare the returned value to the value you PASSED — never to a description of it. A confident label (evidenceRef NOW SET: printed above the untouched original) is indistinguishable from a verification in a transcript. Diff the actual result against your actual input, not against a claim about it.
• Find the untested axis. Thorough coverage of ONE axis reads as thorough coverage overall. Ask what every one of your tests shares — a healthy manifest, a default option value, the happy path — and treat that shared assumption as the dimension you never tested.
• A syntax check proves parseability and nothing else. A clean node --check / lint / parse pass is the covered axis; boot and runtime are the untested one. Parseable ≠ sound.
• A failure whose shape is a HANG reports nothing. A bare await against a stated deadline that never re-checks cannot fail loudly. Race it against a timer so failure has a shape you can see.
• A completeness inventory read through a truncating display is worthless. When deciding which occurrences to change, count with grep -c / grep -o / full-line output — never cut, head, or a pager, which can hide a match past the cut. Distinguish "I found N" (a count) from "I saw N" (a display). Audit multiline prose by paragraph, not by line — a line filter both misses long-line matches and false-flags paragraphs whose companion text is on the next line. Then re-audit with a different method than the one that built the inventory — same-method re-checking reproduces the blind spot. (Empty/short output is a claim about your COMMAND until re-proven a second way.)

Why This Matters

From 24 failure memories:

• your human partner said "I don't believe you" - trust broken
• Undefined functions shipped - would crash
• Missing requirements shipped - incomplete features
• Time wasted on false completion → redirect → rework
• Violates: "Honesty is a core value. If you lie, you'll be replaced."

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

The Bottom Line

No shortcuts for verification.

Run the command. Read the output. THEN claim the result.

This is non-negotiable.
