cook

A simple CLI for orchestrating Claude Code, Codex, and OpenCode.

# review loop
cook "Implement dark mode" review

# 3 passes
cook "Implement dark mode" x3

# race 3, pick best
cook "Implement dark mode" v3 "least code"

# two approaches, pick one
cook "Auth with JWT" vs "Auth with sessions" pick "best security"

# task list
cook "Work on next task in plan.md" review ralph 5 "DONE if all tasks complete, else NEXT"

Two ways to get it:

Skill (no CLI) — your agent orchestrates subagents directly:

mkdir -p .claude/skills/cook && curl -fsSL https://raw.githubusercontent.com/rjcorwin/cook/main/no-code/SKILL.md -o .claude/skills/cook/SKILL.md

CLI — standalone tool for terminal or CI:

npm install -g @let-it-cook/cli
mkdir -p .claude/skills && cp -r $(npm root -g)/@let-it-cook/cli/skill .claude/skills/cook

Requires Node.js 20+ and Claude Code, Codex, or OpenCode.

Primitives

Work — a prompt string. One agent call.

Loop operators wrap work with iteration:

• xN — N sequential passes
• review — review → gate → iterate loop (up to 3 by default)
• ralph N "<gate>" — repeat until a gate says DONE

Composition operators run parallel branches then resolve:

• vN — N identical branches, pick the best
• vs — two different branches, pick the best
• pick, merge, compare — resolvers

Operators compose left to right. Each wraps everything to its left.

cook "work" x3 review       # 3 passes, then review loop
cook "work" review x3       # review loop, repeated 3 times
cook "work" review v3       # race 3, each with a review loop

Review loop

cook "Add dark mode" review                    # default prompts, up to 3 iterations
cook "Add dark mode" review 5                  # up to 5 iterations
cook "Add dark mode" "Review for accessibility" "DONE if WCAG AA, else ITERATE"
cook "Add dark mode" review --work-agent codex --review-agent claude --review-model opus

Rate-limit recovery

When an agent hits a token quota or rate limit, cook automatically waits and retries instead of bailing. A countdown is shown in the TUI. Enabled by default.

cook "Build the feature" review --no-wait   # disable: fail immediately on rate limit

Configure in .cook/config.json:

{
  "retry": {
    "enabled": true,
    "pollIntervalMinutes": 5,
    "maxWaitMinutes": 360
  }
}

Configuration

cook init

Creates COOK.md (project instructions + prompt template) and .cook/config.json:

{
  "agent": "claude",
  "sandbox": "agent",
  "steps": {
    "work":   { "agent": "codex", "model": "gpt-5-codex" },
    "review": { "agent": "claude", "model": "opus" }
  },
  "env": ["CLAUDE_CODE_OAUTH_TOKEN"]
}
