What is claude-plugins CLAUDE.md?

Repository instructions for Claude Code plugins, which are add-ons that extend an AI coding tool. They explain how the repository is organised and where plugin examples and configuration files are found.

Use them when adding or updating a plugin, locating manifests and components, browsing examples, or checking the marketplace configuration.

They give an agent a consistent way to navigate the repository and understand how standalone plugins are structured before making changes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03410	$0.03410
Opus 5.5	$0.01364	$0.01364
Sonnet 5.5	$0.00682	$0.00682
Haiku 4.5	$0.00341	$0.00341

Security

Grade A, and why

claude-plugins CLAUDE.md 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 2mo 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Understanding This Repository's Structure

This repository uses a flat structure where each top-level directory represents a single, standalone plugin. There is no nesting or categorization - every plugin directory sits at the root level. The repository includes a marketplace file (.claude-plugin/marketplace.json) to enable easy discovery and installation.

To browse available plugins:

ls -d */

Each plugin directory contains its own .claude-plugin/plugin.json manifest, README.md, and optional component directories (commands, agents, skills, hooks, MCP config).

Finding Examples

Official Reference Repositories:

anthropics/claude-code - Official Claude Code plugins
anthropics/skills - Official Skills collection

Note: Like this repository, the official repositories use .claude-plugin/marketplace.json to enable plugin discovery. You can browse the marketplace file to understand their structure and locate individual plugins.

To explore plugins in this repository:

Browse plugin directories at the root level
Read plugin READMEs to understand their purpose and capabilities
Examine component directories within plugins:
- commands/ - Slash command instruction files
- agents/ - Subagent configuration files
- skills/ - Skill directories with SKILL.md
- hooks/ - Event hook configurations
- .mcp.json - MCP server configurations

Planning a New Plugin

IMPORTANT: Always Plan Before Creating

When a user requests a new plugin, ALWAYS start with planning. Never immediately create files. Follow this process:

Understand the Request
- What problem does this plugin solve?
- What capabilities should it provide?
- What are the expected inputs and outputs?

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.
