opc-qa

opc-qa is a skill for Claude Code, Codex from vectie/moonclaw. It costs 13 tokens per session (83 once invoked), scanned A, original, Apache-2.0.

A quality-assurance guide for checking what software actually does and recording evidence for each result. QA means testing a product against its intended behavior.

In plain words
What is it for?
Planning checks, documenting observed behavior, isolating bugs, and reporting confidence in pass or fail results.
Why use it?
It prevents reports from relying on assumptions and makes failures reproducible and actionable.

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

opc-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 7d 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

OPC QA

Use this skill for operator-style QA.

Required behavior:

  • verify actual behavior, not desired behavior
  • describe evidence for pass or fail
  • isolate reproducible issues
  • make the bug report concise and actionable

Preferred output:

  • scenarios checked
  • observed behavior
  • failures
  • confidence
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.
