mcp-codex-worker: Skill for Claude Code

.claude/skills/worker-validation-and-qa/SKILL.md

worker-validation-and-qa is a skill for Claude Code from sorryorc/mcp-codex-worker. It costs 30 tokens per session (191 once invoked), scanned A, original, MIT.

A checklist and evidence standard for reviewing changes made by coding workers or automated agents. It distinguishes passing tests from proof that the result is semantically correct.

In plain words
What is it for?
Use it before accepting worker output to review tests, repository scope, execution receipts, missing checks, and the need for independent semantic review.
Why use it?
It helps prevent incomplete, unsafe, or misunderstood work from being accepted just because a command ran or a test passed.

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

worker-validation-and-qa 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 6d 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

Worker Validation And QA

Evidence Bar

  • Passing checks prove only the checked behavior.
  • A receipt proves runtime execution shape, not semantic correctness.
  • A low trajectory score is a review signal.
  • Critical tasks need independent semantic review or main-thread review.

Acceptance Checklist

  • Relevant tests passed.
  • Scope is clean.
  • Receipt abnormal verdict is accepted or explicitly handled.
  • Episode has no unexpected missing gates.
  • No new blocking behavior without blocking_policy=enforce.

When Not To Use

Do not use this for writing user-facing docs. Use worker-docs-and-writing.

Verification

  • npm test
  • npm run codex:guard

Provenance and maintenance

Add failed QA cases to tests before changing acceptance rules.

Changes

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.
