Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy

At a glance

Wrap any command-line tool into a JSON-emitting agent skill.

  • Works in 5 steps: Introspect the CLI (do not guess) → Define the output contract → Define the error contract → …
  • You want to make a CLI reliably callable and parseable by an AI agent — introspect its --help
  • SKILL.md covers When to use, Step 1 — Introspect the CLI…, Step 2 — Define the output… and Step 3 — Define the error…, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

CLI Anything is an agent skill from coco-research/coco. Wrap any command-line tool into a JSON-emitting agent skill. Use when you want to make a CLI reliably callable and parseable by an AI agent — introspect its --help, define a structured-output (--json) contract and a stable error contract, then generate a SKILL.md wrapper with verified examples. Triggers on "wrap this CLI", "make X agent-usable", "generate a skill for this command", "turn a tool into an agent skill".

Its SKILL.md is about 860 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 AI & LLM Engineering, covering Structured output and tool calling. The repository describes itself as: CoCo Super Intelligence is the orchestration layer that turns Claude Code, Cursor, or Codex into an engineering department: a routed advisory board, 226 skills, 386 commands…

When your agent uses it

  • You want to make a CLI reliably callable and parseable by an AI agent — introspect its --help
  • Define a structured-output (--json) contract and a stable error contract
  • Then generate a SKILL.md wrapper with verified examples
  • Make X agent-usable

Example prompts

  • “wrap this CLI”
  • “make X agent-usable”
  • “generate a skill for this command”
  • “/cli-anything”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Introspect the CLI (do not guess)
  2. Define the output contract
  3. Define the error contract
  4. Write the SKILL.md wrapper
  5. Verify against reality

What it can do on your machine

Read from SKILL.md and the folder at commit 6036e9c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    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

CLI Anything loads about 858 tokens when it runs. Until then it costs about 108 tokens; SKILL.md has 423 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~858

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 423 words (~858 tokens).

“Turn any command-line tool into something an AI agent can call reliably and parse. The output is a thin, well-documented wrapper contract — never a reimplementation of the tool. Use the real tool; document how to drive it.”
