description	Use when about to declare work done, fixed, or passing, before committing or opening PRs - demands executing verification commands and reading their output before making any success assertions; evidence precedes claims always

Completion Gate

Overview

Declaring work complete without verification is dishonesty, not efficiency.

Core principle: Evidence precedes assertions, always.

No exceptions. No workarounds. No shortcuts.

The Prime Directive

NO COMPLETION ASSERTIONS WITHOUT FRESH VERIFICATION OUTPUT

If the verification command has not been executed in this message, you cannot assert it passes.

The Entry Protocol

BEFORE asserting any status or expressing confidence:

1. IDENTIFY: Which command substantiates this assertion?
2. EXECUTE: Run the FULL command (fresh, complete)
3. INSPECT: Read every line of output, check exit code, tally failures
4. CONFIRM: Does the output support the assertion?
   - If NO: Report actual status with evidence
   - If YES: State the assertion WITH supporting evidence
5. ONLY THEN: Make the assertion

Skipping any step = fabrication, not verification

Verification Requirements

Assertion	Demands	Insufficient
Tests pass	Test runner output showing 0 failures	Prior run, "should pass"
Linter clean	Linter output showing 0 errors	Partial scan, extrapolation
Build succeeds	Build command with exit code 0	Linter passing, log fragments
Bug resolved	Original symptom tested and passes	Code modified, assumed fixed
Regression test valid	Red-green cycle confirmed	Single green pass
Agent finished	VCS diff showing actual changes	Agent self-reported "done"
Specification met	Line-by-line requirement checklist	Tests passing alone

Guardrails - HALT

• Using hedging language: "should", "probably", "seems to"
• Expressing premature satisfaction ("Done!", "Perfect!", "All good!")
• About to commit/push/open PR without verification
• Trusting an agent's self-reported success
• Relying on partial or stale verification
• Thinking "just this one time"
• Fatigued and wanting to wrap up
• ANY phrasing that implies success without having run verification

Cognitive Traps

Rationalization	Truth
"Should work now"	EXECUTE the verification
"I'm confident"	Confidence is not evidence
"Just this once"	No exceptions
"Linter passed"	Linter is not the compiler
"Agent reported success"	Verify independently
"I'm tired"	Fatigue is not justification
"Partial check is enough"	Partial proof is no proof
"Different wording so rule doesn't apply"	Intent over technicality

Verification Patterns

Tests:

CORRECT: [Run test command] [Output: 34/34 pass] "All tests pass"
WRONG: "Should pass now" / "Looks correct"

Regression tests (Red-Green cycle):

CORRECT: Write -> Run (pass) -> Revert fix -> Run (MUST FAIL) -> Restore -> Run (pass)
WRONG: "I've written a regression test" (without red-green confirmation)

Build:

CORRECT: [Run build] [Output: exit 0] "Build passes"
WRONG: "Linter passed" (linter does not validate compilation)

Specification compliance:

CORRECT: Re-read plan -> Create checklist -> Verify each item -> Report gaps or completion
WRONG: "Tests pass, phase done"

Agent delegation:

CORRECT: Agent reports done -> Check VCS diff -> Verify changes -> Report actual state
WRONG: Trust agent report at face value

Verifying Configuration Changes

When testing changes to configuration, providers, feature flags, or environment settings:

Do not merely confirm the operation succeeded. Confirm the output reflects the intended change.

The Silent Fallback Problem

An operation can succeed because some valid configuration exists, even if it is not the configuration you intended to apply.

Change	Insufficient	Required
Switch LLM provider	HTTP 200	Response body contains expected model identifier
Toggle feature flag	No errors	Feature behavior observably active
Change environment	Deployment succeeds	Logs/variables reference the new environment
Set credentials	Authentication succeeds	Authenticated identity is the correct one

Configuration Verification Sequence

BEFORE asserting a configuration change works:

1. IDENTIFY: What should be DIFFERENT after this change?
2. LOCATE: Where is that difference observable?
3. EXECUTE: Command that exposes the observable difference
4. CONFIRM: Output contains the expected difference
5. ONLY THEN: Assert the configuration change works

Warning signs:
  - "Request succeeded" without inspecting content
  - Checking status code but ignoring response body
  - Confirming no errors but lacking positive confirmation

Verifying UI Work

When asserting UI work is complete:

Assertion	Demands	Insufficient
Component matches design	Visual comparison against UX reference	"It looks right to me"
Responsive design works	Tested at mobile, tablet, desktop breakpoints	Desktop-only check
Accessibility passes	Screen reader test + keyboard navigation + contrast check	"I added aria labels"
Design tokens applied	Spacing/colors/typography match token values	"I used the right classes"

Why This Matters

From accumulated failure patterns:

• your human partner said "I don't believe you" — trust shattered
• Undefined functions shipped — immediate 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 or completion claims
• ANY expression of satisfaction
• ANY positive statement about work state
• Committing, PR creation, task completion
• Transitioning to the next task
• Delegating to agents

Rule applies to:

• Exact phrases
• Paraphrases and synonyms
• Implications of success
• ANY communication suggesting completion or correctness

The Bottom Line

There are no shortcuts for verification.

Execute the command. Read the output. THEN state the result.

This is non-negotiable.
