Overview
A Claude Code plugin and skill that lets Claude run `codex exec` and resume Codex sessions for code analysis, refactoring and editing. Claude asks for the model and reasoning effort, picks a sandbox mode (read-only for analysis), and summarizes the output. Stderr thinking tokens are suppressed with `2>/dev/null` by default to save context.
Who it is for: Claude Code users who want to hand tasks to the Codex CLI
Strengths
- Installs as a Claude Code plugin via marketplace, or as a standalone skill copy
- Defaults to read-only sandbox for analysis tasks
- Hides Codex thinking tokens by default to keep context small
- Asks for model and reasoning effort unless the prompt already sets them
Weaknesses
- Requires the separate `codex` CLI installed with valid credentials
- Legacy models such as gpt-5.5 are rejected for ChatGPT-account sign-ins
- Operational details live in SKILL.md, not the README
- No tagged release, so versioning is unknown
What it needs
- no GPU
- Needs Claude Code, Codex CLI
- Models: gpt-6-astra, gpt-6.1-sol, gpt-6-sol, gpt-6-luna, gpt-5.6-sol
