# Codex Review

Get an independent GPT-5.4 review via codex CLI. Use this proactively after finishing non-trivial work, or when you want a second opinion before proceeding.

## When to use

- After writing a significant chunk of code
- Before presenting an architecture decision to the ape
- When you're unsure about an approach
- After a refactor to catch regressions
- When the critic skill feels too heavy (critic is for decisions, this is for code review)

## Execution

Run this command via Bash, substituting the review request:

```bash
codex exec -c 'reasoning_effort="high"' "Review: $ARGUMENTS. Read all relevant files. Be specific — file paths, line numbers, exact issues. What bugs, edge cases, or design problems exist? Do NOT spawn sub-agents. Answer directly in bullet points." 2>&1
```

**Can run in background** (`run_in_background: true`) if you have other work to do in parallel.

## Output

Present the codex findings to the ape as:
- Issues found (if any)
- Agreements with your approach (if reviewing your own work)
- Disagreements to address

If codex found real issues in your code, fix them before presenting to the ape. Apes don't do tasks.
