# Create Cowork Plugin Build a new plugin from scratch through guided conversation. Walk the user through discovery, planning, design, implementation, and packaging — delivering a ready-to-install `.plugin` file at the end. ## Overview A plugin is a self-contained directory that extends Claude's capabilities with commands, skills, agents, hooks, and MCP server integrations. This skill encodes the full plugin architecture and a five-phase workflow for creating one conversationally. The process: 1. **Discovery** — understand what the user wants to build 2. **Component Planning** — determine which component types are needed 3. **Design & Clarifying Questions** — specify each component in detail 4. **Implementation** — create all plugin files 5. **Review & Package** — deliver the `.plugin` file > **Nontechnical output**: Keep all user-facing conversation in plain language. Do not expose implementation details like file paths, directory structures, or schema fields unless the user asks. Frame everything in terms of what the plugin will do. ## Plugin Architecture ### Directory Structure Every plugin follows this layout: ``` plugin-name/ ├── .claude-plugin/ │ └── plugin.json # Required: plugin manifest ├── commands/ # Slash commands (.md files) ├── agents/ # Subagent definitions (.md files) ├── skills/ # Skills (subdirectories with SKILL.md) │ └── skill-name/ │ ├── SKILL.md │ └── references/ ├── ....
