Three-phase project mode for Claude Code: Claude plans, Codex executes, Claude reviews — execution burns your ChatGPT limits, not your Claude limits.
You get Fable-quality planning plus Codex execution without burning your Claude usage on the heavy lifting. The models work in sequence, each at their best effort level.
- Claude Code installed
- Codex CLI:
npm install -g @openai/codex
thencodex login
(requires paid ChatGPT Plus subscription) - Codex plugin in Claude Code:
/plugin marketplace add openai/codex-plugin-cc
/plugin install codex@openai-codex
git clone https://github.com/responsiblparty/cc-doubleteam
cp -r cc-doubleteam/skills/doubleteam ~/.claude/skills/doubleteam
Optionally copy CLAUDE.md
contents into your project's CLAUDE.md
to enable proactive suggestions:
cat cc-doubleteam/CLAUDE.md >> /path/to/your/project/CLAUDE.md
Restart Claude Code after install. Type /doubleteam
to confirm it's working.
/doubleteam <task>
— starts immediately with your task/doubleteam
— Claude asks what the task is- Claude will also proactively suggest it when a session is heading into a substantial build
| Phase | Model | Effort | Role |
|---|---|---|---|
| 1 — Plan | Claude Fable (fallback: Opus) | high | Produces step-by-step implementation plan; s for your approval |
| 2 — Execute | Codex | xhigh | Implements the plan; burns ChatGPT limits, not Claude limits |
| 3 — Review | Claude Fable (fallback: Opus) | max | Reviews output against plan; flags issues without rewriting |
just plan
→ Phase 1 onlyskip review
→ Phases 1 and 2 only- If Codex is unavailable → falls back to Claude execution (noted in output)
