Use when creating a new Claude Code plugin or setting up plugin structure - provides complete file organization, manifest format, and component definitions for commands, agents, skills, hooks, and MCP servers.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Creating a Plugin

## Overview

A **Claude Code plugin** packages reusable components (commands, agents, skills, hooks, MCP servers) for distribution. Create a plugin when you have components that work across multiple projects.

**Don't create a plugin for:**
- Project-specific configurations (use `.claude/` in project root)
- One-off scripts or commands
- Experimental features still in development

**Plugin storage locations:**
- Development: Anywhere during development, installed via `file:///` path
- User-level: `~/.claude/plugins/` (after installation)
- Project-level: `.claude/plugins/` (project-specific installations)

## Quick Start Checklist

Minimal viable plugin:

1. Create directory: `my-plugin/`
2. Create `.claude-plugin/plugin.json` with at minimum:
   ```json
   {
     "name": "my-plugin"
   }
   ```
3. Add components (commands, agents, skills, hooks, or MCP servers)
4. Test locally: `/plugin install file:///absolute/path/to/my-plugin`
5. Reload: `/plugin reload`

## Directory Structure

```
my-plugin/
 .claude-plugin/
    plugin.json              # Required: plugin manifest
 commands/                    # Optional: slash commands
    my-command.md

How to install

The exact contents, by fingerprint
mdr add ed3dai/ed3d-plugins/creating-a-plugin@sha256:0bc6e7f1e798ad05

The line at the top of this page pins the label git:20260204.611bfd1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
