claude-plugins CLAUDE.md

claude-plugins CLAUDE.md is an instructions file for coding agents from MisterClean/claude-plugins. It costs 440 tokens per session, scanned A, original, MIT.

Project instructions for a repository of Claude Code plugins, which are add-ons that give Claude specialized workflows and knowledge. They describe the repository layout and the files, metadata, references, and examples each plugin skill can contain.

In plain words
What is it for?
Use them when developing, documenting, or reviewing Claude Code plugins and their skill files, frontmatter, references, or examples.
Why use it?
They help an agent follow the repository's conventions when creating or changing plugins. This avoids misplaced files or incomplete skill definitions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

claude-plugins 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 4d 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.

Skill Anatomy

Each skill has:

  • SKILL.md: Main file with YAML frontmatter (name, description, version) and markdown body containing workflows, examples, and troubleshooting
  • references/: Deep-dive documentation loaded when Claude needs more detail
  • examples/: Working code that Claude can adapt

Key Conventions

SKILL.md Frontmatter

---
name: skill-name
description: This skill should be used when the user asks to "specific phrase 1", "specific phrase 2", or mentions specific-topic.
version: 1.0.0
---

The description field should contain specific trigger phrases users would say, not vague descriptions.

Content Guidelines

  • Verify APIs/endpoints before documenting - never guess
  • Include working curl commands and code snippets
  • Document common errors and edge cases
  • Keep SKILL.md concise; put detailed docs in references/

Working on This Repo

When adding a new skill:

  1. Create folder: skills/<skill-name>/
  2. Add SKILL.md with proper frontmatter
  3. Add references/ and examples/ as needed
  4. Update skills/README.md with the new skill
  5. Update CHANGELOG.md

When modifying existing skills:

  • Bump version in frontmatter according to semver
  • Update CHANGELOG.md

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.
