cargo-coupling: Skill for Claude Code

.agents/skills/analyze/SKILL.md

analyze is a skill for Claude Code from nwiizo/cargo-coupling. It costs 34 tokens per session (303 once invoked), scanned A, original, MIT.

A skill for measuring how closely parts of a Rust project depend on one another and explaining the results. It can produce summaries, histories, hotspots, impact views, and checks for quality thresholds.

In plain words
What is it for?
Use it to inspect module coupling, find hotspots, compare results with a baseline, assess a module’s impact, or run a CI quality check.
Why use it?
It shows where code is tightly connected or difficult to change, helping developers identify maintenance risks and likely problem areas.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is nwiizo/cargo-coupling's own configuration. It tells Claude Code how to work on cargo-coupling itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cargo-coupling configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analyze scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Coupling Analysis

Run the requested analysis from this repository, using ./src when no target is specified. Choose the output mode that answers the request; one report is usually enough. For interpretation, AI output includes the analysis manifest:

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

Use command examples for history, baseline, machine-readable output, or other requested modes. Read coupling --help for options not covered there; pass CLI arguments, not slash-command labels.

Explain the reported grade and its rationale, the consequential findings, and the analysis limits. Check relevant source and configuration before turning a signal into a refactoring recommendation. Preserve Git history, thresholds, and subdomain classification when comparing results; never change them to improve the grade.

Use the balance model when a finding needs semantic interpretation. The report example is optional for a detailed report. A summary request needs only the result and material limits. Analysis is complete when the requested results and supporting evidence are explained; implement changes when the user also requests them.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

analyze is a skill published in the GitHub repository nwiizo/cargo-coupling (116 stars, last pushed 2d ago), licensed MIT. It adds 34 tokens to every session and 303 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
