qa-regression-check

qa-regression-check is a skill for Claude Code, Codex from joinwell52-AI/CodeFlowMu-open. It costs 39 tokens per session (172 once invoked), scanned A, original, MIT.

A focused quality-assurance checklist for checking whether a CodeFlowMu change could break nearby workflows.

In plain words
What is it for?
Use it to identify impacted workflows, run targeted checks, and record remaining testing gaps after a CodeFlowMu change.
Why use it?
It keeps regression testing limited to affected areas and makes untested parts explicit instead of treating them as safe.

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

qa-regression-check 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

QA Regression Check

When to use

Use when a change may affect nearby workflows.

Rules

  • Define impacted workflows.
  • Keep regression scope focused.
  • Record gaps honestly.
  • Escalate broad audit requests to PM.

Required output

Use docs/skills/qa-playbook/regression-check.md.

Forbidden actions

  • Do not expand into full audit unless tasked.
  • Do not claim untested workflows are safe.
  • Do not mutate lifecycle.

Minimal example

Workflow: skill validation
Why impacted: new SKILL.md folders
Check: quick_validate.py over skills/*
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.
