Review Rust module boundaries and implicit coupling using cargo-coupling and source evidence.

  • Focused modularity reviews
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Not prose reviews

What it does

Coupling Review is an agent skill from nwiizo/cargo-coupling. Review Rust module boundaries and implicit coupling using cargo-coupling and source evidence. Use for focused modularity reviews, not prose reviews.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Rust. 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

  • Focused modularity reviews
  • Not prose reviews

Example prompts

  • “/coupling-review”

What it can do on your machine

Read from SKILL.md and the folder at commit 8ef1441. 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 (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

Coupling Review loads about 425 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 191 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~425

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.

Modularity Review

Review the requested scope (default ./src) for changes that would force unrelated modules to change together. Reuse a current report or obtain one:

bash
rtk proxy cargo run -- coupling --ai ./src

Read the target's .coupling.toml and the source behind consequential findings. Use the balance model for interpretation. Missing subdomain configuration is uncertainty to explain, not a reason to block a review or invent business classifications.

Focus semantic inspection on knowledge shared across boundaries: duplicated rules, shared constants or ordering assumptions, and co-changing files without an AST edge. Separate code evidence from assumptions about teams, deployments, or runtime behavior that static analysis cannot establish. Check the analysis manifest before calling a report clean.

Prioritize supported findings by change impact and essential volatility. Preserve expected entrypoint fan-out, stable hubs, and re-export facades. Keep configuration and history comparable; grade improvement alone is not evidence of better design.

Report findings with file locations, shared knowledge, likely impact, and a specific recommendation. Include sound design choices and relevant blind spots; omit empty sections. Use history or baseline analysis only when trend or PR context matters. The review is complete when its findings and limits are supported; implementation is a separate user-requested action.
