qa is a skill for Claude Code, Codex from SZoloth/skill-pack. It costs 66 tokens per session (1,720 once invoked), scanned A, original, MIT.

A review procedure that checks all changes in a coding session with Codex as a second reviewer. It examines the Git diff and surrounding project context.

In plain words
What is it for?
Use it after implementation to review the working tree, collect the complete diff, and produce actionable findings about the changes.
Why use it?
It helps find defects, omissions, and risky changes before they are committed or released.

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 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 1mo 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.

QA — Codex-Powered Change Review

Thorough QA on all changes in the current working tree using Codex as a second pair of eyes. Detects what changed, sends it to Codex for deep review, and presents actionable findings.

When to Use

  • After completing implementation work, before committing
  • User says "QA", "full QA", "QA my changes", "review with codex"
  • Any time you want a second opinion on everything you just built

Process

Step 1: Gather All Changes

# Get the full picture
git status --porcelain
git diff --stat
git diff --cached --stat

# Capture the actual diff (staged + unstaged)
git diff HEAD > /tmp/qa-full-diff.patch

If changes span many files, also get a summary:

git diff HEAD --name-only

Step 2: Build Context

Before sending to Codex, gather context about what was being built:

  • What task/feature was being implemented?
  • What files were touched and why?
  • Any known areas of concern?

Summarize this in 2-3 sentences to give Codex context.

Step 3: Codex Review (diff-based)

Run Codex with the full diff and context. Use -C to point at the repo so Codex can read surrounding code.

cat <<'PROMPT' | codex exec --full-auto -C "$(git rev-parse --show-toplevel)" -o /tmp/qa-codex-review.md -
You are doing a thorough QA review of the following changes. Be critical — find real bugs, not style nits.

## Context
[2-3 sentence summary of what was built]

## Your Review Checklist
1. **Correctness**: Logic errors, off-by-ones, wrong conditions, missing edge cases
2. **Runtime errors**: Null/undefined access, type mismatches, missing imports
3. **Security**: Injection, XSS, secrets in code, unsafe operations
4. **Data integrity**: Race conditions, stale state, missing validation
5. **Integration**: Does this work with the rest of the codebase? Missing wiring?
6. **Regressions**: Could these changes break existing functionality?
7. **Missing pieces**: Anything obviously incomplete or TODO'd?

## Changes to Review
$(git diff HEAD)

For each issue found, report:
- **File:line** — exact location
- **Severity** — P1 (bug/security), P2 (likely problem), P3 (minor concern)
- **Issue** — what's wrong
- **Fix** — how to fix it

If the changes look solid, say so — don't manufacture issues.

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.
