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

Manual copy

  • Setup questions
  • Calls cargo

What it does

Cargo Coupling is an agent skill from nwiizo/cargo-coupling. Explain cargo-coupling CLI options and .coupling.toml configuration. Use for command or setup questions.

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `commands.md`).

It sits in Testing & QA. The repository describes itself as: A coupling analysis tool for Rust projects - measuring the 'right distance' in your code. The licence is MIT.

When your agent uses it

  • Setup questions

Example prompts

  • “/cargo-coupling”

What it can do on your machine

Read from SKILL.md and the folder at commit aa0d18b. 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

    Shell commands in SKILL.md call:

    • cargo

    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

Cargo Coupling loads about 290 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 118 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~290

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.

cargo-coupling CLI Guidance

Answer the requested command or configuration question with the smallest useful example. Run commands from this repository; an external project is the analysis path, not the directory from which to run this package's cargo run.

bash
rtk proxy cargo run -- coupling --help
  • Read commands.md for examples of analysis modes and configuration.
  • Use analyze when asked to run and interpret an analysis.
  • Use web when asked to launch the visualization.

Check current help and CLI definitions for precise flag behavior. For configuration precedence or pattern matching, inspect config.rs and the repository's .coupling.toml. Exclusion patterns are relative to the config directory; the config search starts at the analysis path and walks upward. Subdomains describe business-driven volatility and must not be relabeled to hide findings.
