clean-architecture-skills: Instructions file for Claude Code

CLAUDE.md

clean-architecture-skills CLAUDE.md is an instructions file for Claude Code from nathankim0/clean-architecture-skills. It costs 1,155 tokens per session, scanned A, original, MIT.

A repository instruction file for maintaining a collection of coding-agent skills and their marketplace manifests. It documents the repository layout, versioning rules, supported tools, and required release steps.

In plain words
What is it for?
It guides changes to skill files, plugin manifests, marketplace catalogs, documentation, and the commit, push, tagging, and release workflow.
Why use it?
It gives coding agents consistent project-specific rules and helps prevent broken links, incorrect manifests, private information, or unfinished releases. It also records which files are authoritative when several agent tools use the repository.

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

clean-architecture-skills CLAUDE.md scanned grade A with 1 finding 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Guidance for coding agents working in this repository. AGENTS.md is a symlink to this file, so edit only CLAUDE.md.

Overview

A plugin marketplace that ships two agent skills:

  • clean-architecture: Clean Architecture review and design guidance
  • kent-beck-style: Kent Beck simple design and refactoring guidance

The same skills are distributed to Claude Code, OpenAI Codex, pi, OpenClaw, GitHub Copilot, and Amp. This is a public repository: never add company names, private code, internal URLs, or examples taken from private projects. Rewrite lessons from real work as generic examples.

Layout

Path Role
plugins/<plugin>/skills/<plugin>/SKILL.md Skill body. Frontmatter name must equal the plugin name
plugins/<plugin>/.codex-plugin/plugin.json Canonical plugin manifest
plugins/<plugin>/.claude-plugin/plugin.json Relative symlink to ../.codex-plugin/plugin.json. Never replace it with a copy
.claude-plugin/marketplace.json Claude Code marketplace catalog with per-plugin versions
.agents/plugins/marketplace.json Codex marketplace catalog
package.json pi package; version must equal the marketplace metadata.version
README.md, README.ko.md English and Korean READMEs. Keep them in sync
tests/validation.test.mjs Validates catalogs, manifests, symlinks, and executes TypeScript examples from the skills

Rules

  • The tests run some fenced typescript examples from SKILL.md files (located by signature, such as async execute(). Keep those examples valid and behaviorally correct when editing them.

  • Keep skill descriptions under 1024 characters and plugin names in kebab-case.

  • When a skill changes behavior or guidance, update both READMEs if they describe that behavior.

  • Run the validation before every commit:

    node --test

Versioning

  • Plugin versions (plugins/<plugin>/.codex-plugin/plugin.json and the matching entry in .claude-plugin/marketplace.json) follow semver per plugin:
    • patch: wording fixes, corrected examples
    • minor: new guidance, checklist items, or sections
    • major: removed or renamed skills, incompatible structure
  • The repository version (package.json version and .claude-plugin/marketplace.json metadata.version) increases with every release: minor when any plugin gains features, patch otherwise.
  • Documentation-only or tooling-only changes (README, this file, CI) may ship without a plugin bump but still bump the repository patch version when released on their own.

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.
