# create-plugin

Walks you from a rough plugin idea to a tested directory: requirements, component plan, clarifying questions, then the actual files. Useful when you want your own plugin but the layout rules are unfamiliar.

## What it does

The command runs in phases. It starts by pinning down what the plugin is for and who will use it, then draws up a component list: skills, subagents, hooks, MCP servers, settings. That plan is shown as a table with counts and purposes, and nothing gets built until you confirm it.

Design comes next, and it is the phase the command refuses to skip. You get concrete questions per component — which user queries should fire a skill, whether it needs utility scripts, what belongs in `SKILL.md` versus `references/`. Then the directory tree appears, along with a `plugin.json` manifest, `README.md`, a `.gitignore`, and a git repo if you are starting fresh.

Implementation leans on the plugin-dev skills: before each component type the command loads the matching one (skill-development, agent-development, hook-development, mcp-integration). For new plugins it advises writing user-invoked slash commands as skills under `skills/<name>/SKILL.md`; the `commands/` directory is kept as a legacy option. TodoWrite tracks progress, and agent-creator, plugin-validator and skill-reviewer handle validation.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin install plugin-dev@claude-plugins-official
```

2. **Manually: put the files in place**
- File: `.claude/commands/create-plugin.md` — Call it with /create-plugin. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/create-plugin.md` — Call it with /prompts:create-plugin. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/create-plugin.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/create-plugin.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-plugins-official/tree/HEAD/plugins/plugin-dev/commands/create-plugin.md

## When to use it
- design a plugin structure from scratch
- decide which components a plugin needs
- produce a valid `plugin.json` and directory layout
- split a skill between `SKILL.md` and `references/`
- validate a plugin before publishing it

## Example prompts
- Build a plugin that checks migrations before deploy
- I want a plugin with a save hook and a review skill
- Create a plugin for our internal API — description: task service integration

# Plugin Creation Workflow

Guide the user through creating a complete, high-quality Claude Code plugin from initial concept to tested implementation. Follow a systematic approach: understand requirements, design components, clarify details, implement following best practices, validate, and test.

## Core Principles

- **Ask clarifying questions**: Identify all ambiguities about plugin purpose, triggering, scope, and components. Ask specific, concrete questions rather than making assumptions. Wait for user answers before proceeding with implementation.
- **Load relevant skills**: Use the Skill tool to load plugin-dev skills when needed (plugin-structure, hook-development, agent-development, etc.)
- **Use specialized agents**: Leverage agent-creator, plugin-validator, and skill-reviewer agents for AI-assisted development
- **Follow best practices**: Apply patterns from plugin-dev's own implementation
- **Progressive disclosure**: Create lean skills with references/examples
- **Use TodoWrite**: Track all progress throughout all phases

**Initial request:** $ARGUMENTS

## Phase 1: Discovery

**Goal**: Understand what plugin needs to be built and what problem it solves

**Actions**:

1. Create todo list with all 7 phases
2. If plugin purpose is clear from arguments:
   - Summarize understanding
   - Identify plugin type (integration, workflow, analysis, toolkit, etc.)
3. If plugin purpose is unclear, ask user:
   - What problem does this plugin solve?
   - Who will use it and when?
   - What should it do?
   - Any similar plugins to reference?
4. Summarize understanding and confirm with user before proceeding

**Output**: Clear statement of plugin purpose and target users

---

## Phase 2: Component Planning

**Goal**: Determine what plugin components are needed

**MUST load plugin-structure skill** using Skill tool before this phase.

**Actions**:

1. Load plugin-structure skill to understand component types
2. Analyze plugin requirements and determine needed components:
   - **Skills**: Specialized knowledge OR user-initiated actions (deploy, configure, analyze). Skills are the preferred format for both — see note below.
   - **Agents**: Autonomous tasks? (validation, generation, analysis)
   - **Hooks**: Event-driven automation? (validation, notifications)
   - **MCP**: External service integration? (databases, APIs)
   - **Settings**: User configuration? (.local.md files)

   > **Note:** The `commands/` directory is a legacy format. For new plugins, user-invoked slash commands should be created as skills in `skills/<name>/SKILL.md`. Both are loaded identically — the only difference is file layout. `commands/` remains an acceptable legacy alternative.

3. For each component type needed, identify:
   - How many of each type
   - What each one does
   - Rough triggering/usage patterns
4. Present component plan to user as table:
   ```
   | Component Type | Count | Purpose |
   |----------------|-------|---------|
   | Skills         | 5     | Hook patterns, MCP usage, deploy, configure, validate |
   | Agents         | 1     | Autonomous validation |
   | Hooks          | 0     | Not needed |
