Rocket Fuel

Fable 5 and Codex, co-founders

One sees the future. One makes it happen. Run Claude Fable 5 and OpenAI Codex as co-founders in a single Claude Code command.

Fable 5 takes the Visionary seat: it interviews you, writes the plan, sets the standards, and reviews the result. Codex takes the Integrator seat: it filters the plan, kills scope creep, builds the code in its own sandbox, and reports honestly. They argue in a bounded meeting until the verdict line says SAME PAGE, and only then does anyone write code. Based on the Visionary/Integrator operating system from Rocket Fuel by Gino Wickman and Mark C. Winters.

You make exactly three decisions per run: the interview answers, rare deadlock tie-breaks, and the final commit. The skill guides you through everything else: it tells you which mode it detected, what happens next, and where every artifact lands.

Install

npm i -g @openai/codex@latest && codex login   # ChatGPT account works, no API key
git clone https://github.com/NulightJens/rocket-fuel-skill.git ~/rocket-fuel-skill
mkdir -p ~/.claude/skills
ln -s ~/rocket-fuel-skill/rocket-fuel ~/.claude/skills/rocket-fuel

Restart Claude Code once. Requirements: Claude Code, Codex CLI 0.130+, git.

Use

One command, plain English. The skill picks the right mode from context:

You sayYou get
/rocket-fuel build me a habit trackerFull kickoff: interview → adversarial plan review → Codex builds → Fable verifies
/rocket-fuel this repo is a mess, clean it upCodebase audit → ranked issue list → you pick 3-7 fixes → build
/rocket-fuel review PLAN.mdCodex attacks your plan read-only until it approves
/rocket-fuel have codex add dark modeOne scoped task, built by Codex, diff-reviewed and proof-run by Fable

From there the skill walks you through it: one interview question at a time with a recommended answer attached, live verdicts from Codex each round, and a clear prompt before anything is committed. The full argument between the two models is saved to SAME-PAGE-LOG.md in your repo, next to PLAN.md.
