Codex CLI Review

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
