What it does

Cook is an agent skill from rjcorwin/cook. Orchestrate coding agents with review loops, parallel races, repeat passes, and task-list progression. Use when: the user asks to "cook" something, wants iterative refinement, wants to race multiple approaches, or needs to work through a task list.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Task breakdown. The repository describes itself as: A simple CLI for orchestrating Claude Code, Codex, and OpenCode.

When your agent uses it

  • : the user asks to cook something
  • Wants iterative refinement
  • Wants to race multiple approaches
  • Needs to work through a task list

Example prompts

  • “/cook”

Requirements

  • Pre-approved tools (allowed-tools): Bash(cook *)

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. The project must have cook init run (creates COOK.md, .cook/config.json)
  2. For composition operators (vs, vN), the working tree must be clean (commit first)

What it can do on your machine

Read from SKILL.md and the folder at commit 9338b09. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(cook *)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cook loads about 1k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 309 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 309 words (~1,021 tokens).

“cook wraps your coding agent (Claude Code, Codex, OpenCode) in composable workflows: review loops, repeat passes, parallel races, and task-list orchestration.”
