Custom-MCPs: Skill for Claude Code

.claude/skills/code-quality/SKILL.md

code-quality is a skill for Claude Code from Edison-Watch/Custom-MCPs. It costs 19 tokens per session (241 once invoked), scanned A, a copy of code-quality, MIT.

A set of instructions for checking code quality in a Python project. It uses formatting, linting, dead-code, type, documentation, and dependency checks.

In plain words
What is it for?
Use it to format files, run individual checks, or run the full quality-check sequence with the project's make commands.
Why use it?
It gives contributors a repeatable way to catch style problems, unused code, type errors, and other issues before changes are committed or merged.

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

code-quality 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 1mo 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

Code Quality Skill

This skill provides instructions for running code quality checks and maintaining standards in the Python-Template project.

Commands

Use the following make targets to ensure code quality:

  • make fmt: Runs the ruff formatter and formats JSON files.
  • make ruff: Runs the ruff linter to catch common errors and style issues.
  • make vulture: Searches for dead code across the project.
  • make ty: Runs the ty type checker to ensure type safety.
  • make ci: Runs all of the above checks (ruff, vulture, import_lint, ty, docs_lint, check_deps) in sequence.

Workflow

  1. Before Committing: Always run make fmt and make ruff.
  2. Major Changes: Run make ci to ensure no regressions in types or dead code.
  3. Continuous Integration: These checks are enforced in the CI pipeline. Ensure all pass before opening a PR.

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.
