At a glance

Interpret cargo-coupling findings using Khononov's strength, distance, and volatility model.

  • SKILL.md covers Qualitative Severity Table and Recognition Rules
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Balanced Coupling is an agent skill from nwiizo/cargo-coupling. Interpret cargo-coupling findings using Khononov's strength, distance, and volatility model.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `model-reference.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

  • Testing & QA work in your project

Example prompts

  • “/balanced-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

    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

    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

Balanced Coupling loads about 516 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 212 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~516

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.

Balanced Coupling Model

Use the model to judge the cost of coordinated change. It is a conceptual lens; exact detection conditions and reported severities come from the current source.

BALANCE = (STRENGTH XOR DISTANCE) OR NOT VOLATILITY

Recognition Rules

  • Where configured, subdomain volatility represents essential, business-driven change and governs scoring. Raw Git churn feeds accidental-volatility diagnostics; it must not manufacture cascading-change risk for a low-essential-volatility target.
  • Binary entrypoints normally have high fan-out and co-change with wired modules.
  • Crate-root re-export facades provide a stable interface; their consumers do not automatically depend on volatile implementation details.
  • High afferent coupling to a stable central abstraction can be good design.
  • Hidden Coupling is temporal co-change without an AST edge. Investigate shared rules or assumptions before diagnosing a defect.

Preserve these distinctions when reviewing or changing detectors. Keep history, thresholds, and subdomain settings comparable; never manipulate them to improve a grade. Include the analysis manifest when interpreting a clean report.

Read model-reference.md only for dimension definitions, subdomain reasoning, or connascence examples. For a particular detector, use explain-issue to locate the implementation.
