Plugin Anatomy

Each plugin follows Claude Code plugin conventions:

<plugin>/
├── .claude-plugin/plugin.json   # Manifest: name, version, description, author
├── skills/<name>/SKILL.md       # Interactive skills (the core logic)
├── commands/<name>.md           # Slash commands (thin wrappers or rich docs)
├── agents/<name>.md             # Autonomous subagents with system prompts
└── hooks/hooks.json             # Event handlers (optional)

Skills are the heart of each plugin — they contain the domain knowledge and workflow logic. Commands are thin wrappers that trigger skills via /plugin:command syntax. Agents run autonomously for tasks like literature surveys or code review.

Not every plugin uses every component. Minimal plugins like deets have only a skill and a command. Larger plugins like worldsmith add hooks for ambient project detection and propagation discipline.
