verification-before-completion

verification-before-completion is a skill for Claude Code, Codex from chemany/Mente. It costs 18 tokens per session (189 once invoked), scanned A, original, MIT.

A checklist for proving that a coding task is really finished before reporting success.

In plain words
What is it for?
It helps agents choose the right verification command, run it, inspect the result, and report the actual status.
Why use it?
It prevents claims based only on code inspection, assumptions, or outdated test results.

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 4d 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

Use this skill before saying a feature is fixed, complete, passing, or ready to ship.

Core rule

No completion claim without fresh verification evidence.

Workflow

  1. Identify the command that proves the claim.
  2. Run the full command now.
  3. Read the output and exit status.
  4. Report the real status with evidence.

Red flags

  • "Should work now"
  • "Looks done"
  • "Probably passes"
  • Claiming success from code inspection alone

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.
