# Codex CLI Review Skill

## Trigger

- Keywords: codex cli review, cli review, script review

## When to Use

- Need Codex to independently explore the entire project (full disk read)
- Don't need MCP's context persistence feature
- Want to use Codex CLI's native review format

## When NOT to Use

- Need iterative review (use `/codex-review-fast --continue`)
- Need to follow up with Codex (use MCP version)
- Only want to see diff without waiting for Codex exploration (use `/codex-review-fast`)

## Difference from MCP Version

| Feature             | CLI Version (this skill) | MCP Version           |
| ------------------- | ------------------------ | --------------------- |
| Independent explore | Full disk read           | Needs explicit instruction |
| Context persistence | None                     | threadId              |
| Iterative review    | Each run independent     | --continue            |
| Format              | Codex native format      | Custom prompt format  |
| Execution method    | Script invocation        | MCP tool invocation   |
