verification-before-completion

verification-before-completion is a skill for Claude Code from ArtemioPadilla/agent-triforce. It costs 43 tokens per session (586 once invoked), scanned A, original, MIT.

A checklist for verifying that a coding task is genuinely complete before claiming success.

In plain words
What is it for?
Use it before declaring a fix or feature finished, committing changes, opening a pull request, or marking work complete.
Why use it?
It requires visible evidence from tests, specific behavior checks, and broader regression checks instead of relying on assumptions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verification-before-completion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Verification Before Completion

Verify: $ARGUMENTS

The Rule

You MUST see evidence before claiming success. "It should work" is not evidence. A passing test run is evidence. A working command output is evidence.

When to Use

  • Before claiming a bug is fixed
  • Before claiming implementation is complete
  • Before committing
  • Before creating a PR
  • Before telling the user "it's done"
  • Before marking a task as completed

The Checklist

Before ANY completion claim, run through these:

  1. Run the tests — see them pass with your own eyes

    Run: {project test command}
    Expected: ALL tests pass
    Actual: {paste actual output}
    
  2. Verify the specific change — does it do what was requested?

    Test: {specific verification for this change}
    Expected: {expected behavior}
    Actual: {paste actual output}
    
  3. Check for regressions — did you break anything else?

    Run: {full test suite or broader test}
    Expected: No new failures
    Actual: {paste actual output}
    
  4. Verify the claim you're about to make — is it actually true?

    • "Tests pass" — did you run them? did you see them pass?
    • "Bug is fixed" — did you reproduce the bug, apply the fix, verify it's gone?
    • "Feature works" — did you exercise the feature and see correct behavior?

Anti-Patterns

"It should work because..." Not evidence. Run it.

"I made the change so it will pass now" Not evidence. Run the tests.

"The logic is correct" Not evidence. See it work.

"I fixed the same kind of bug before" Not evidence for this bug. Verify this fix.

"Tests were passing before my change" They might not be now. Run them again.

Evidence Format

When reporting completion, include actual evidence:

Verification:
- Tests: {N} passing, {0} failing (command: {what you ran})
- Specific: {what you verified and what you saw}
- Regressions: none (full suite passing)

Integration with Agent Workflow

This skill reinforces the SIGN OUT checklist item "Stated build/test results (all passing, or documented what's failing and why)." The difference: this skill requires you to ACTUALLY RUN the verification and SHOW the output, not just state a claim.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
