explain-issue

explain-issue is a skill for Claude Code, Codex from nwiizo/cargo-coupling. It costs 22 tokens per session (540 once invoked), scanned A, original, MIT.

A reference guide for explaining common software-coupling problems, including when they occur and how to fix them.

In plain words
What is it for?
It helps explain coupling findings, show representative code, and suggest fixes such as facades, module splitting, or dependency inversion.
Why use it?
Terms such as inappropriate intimacy or efferent coupling can be hard to interpret without concrete detection rules and examples.

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

explain-issue 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 3d 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

Explain Issue

Explain the specified issue type with overview, detection conditions, code examples, and solution approaches.

Issue Types

Global Complexity

  • Condition: Strong coupling + far distance
  • Formula: STRENGTH >= 0.5 AND DISTANCE >= 0.5
  • Fix: Introduce traits, move modules, facade pattern

Cascading Change Risk

  • Condition: Strong coupling + high volatility
  • Formula: STRENGTH >= 0.5 AND VOLATILITY >= 0.5
  • Fix: Stable interface layer, dependency inversion

Inappropriate Intimacy

  • Condition: Intrusive coupling across boundaries
  • Formula: STRENGTH = 1.0 AND DISTANCE > 0.0
  • Fix: Encapsulation, pub(crate) usage

High Efferent Coupling

  • Condition: Module has too many outgoing dependencies
  • Threshold: Default 15
  • Fix: Module splitting, facade pattern

High Afferent Coupling

  • Condition: Module has too many incoming dependencies
  • Threshold: Default 20
  • Fix: Interface introduction, responsibility distribution

Unnecessary Abstraction

  • Condition: Weak coupling + near distance + low volatility
  • Formula: STRENGTH < 0.3 AND DISTANCE < 0.3 AND VOLATILITY < 0.3
  • Fix: Remove abstraction, use direct implementation

Explanation Structure

For each issue type, include:

  1. Overview: Concise description
  2. Why problematic: Concrete negative impacts
  3. Detection conditions: Formula and thresholds
  4. Code examples: Before/After Rust code
  5. Solution approaches: Multiple resolution methods
  6. Design principles: SOLID, Khononov Balance, Rust idioms

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.

explain-issue is a skill published in the GitHub repository nwiizo/cargo-coupling (96 stars, last pushed 5d ago), licensed MIT. It adds 22 tokens to every session and 540 once invoked, about $0.0001 per session on Opus 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.
