verification-before-completion

verification-before-completion is a skill for Claude Code, Codex from omnigentx/jarvis. It costs 31 tokens per session (324 once invoked), scanned A, original, MIT.

A checklist for verifying software changes before saying they are complete.

In plain words
What is it for?
It is for reviewing builds, running the full test suite, checking edge cases and regressions, and confirming that a reproduced bug no longer occurs.
Why use it?
It reduces the chance of reporting unfinished work by checking code quality, tests, documentation, integration, and bug-fix verification.

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 3d 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.

What it actually says

VERIFICATION BEFORE COMPLETION

<verification_checklist>

BEFORE reporting "done", verify ALL of the following:

Code Quality

  • Code runs without errors
  • No unresolved TODO/FIXME
  • No leftover console.log/print debug statements
  • Code is properly formatted

Testing

  • Unit tests pass
  • Edge cases are covered
  • Test failure messages are clear and descriptive

Documentation

  • Docstrings for new functions
  • README updated if setup changed
  • Inline comments for complex logic

Integration

  • Does not break existing functionality
  • API contracts match spec
  • UI renders correctly across screen sizes </verification_checklist>

<bugfix_protocol> When fixing a bug:

  1. Reproduce the bug (you MUST see it happen)
  2. Apply the fix
  3. Verify the bug NO LONGER occurs
  4. Run the ENTIRE test suite (not just related tests) </bugfix_protocol>

✅ Correct

  • "Verified: tests pass, edge case X handled, no regressions"

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.
