Plugins for knowledge work
Four files,
one specialist.
A plugin is a manifest, a set of tool connections, the commands you invoke, and the skills that fire on their own. Markdown and JSON, no build step.

Inside one plugin
Published structure.claude-plugin/plugin.json
The manifest. What this plugin is.
.mcp.json
The connectors. Which outside tools the role depends on.
commands/
What you invoke. Slash commands you trigger deliberately.
skills/
What fires on its own. The domain knowledge drawn on when relevant.
The split between the triangle and the bar is the whole design: one is a decision you make, the other is a default you set once.
Every component is file-based, so a plugin is readable before it is trusted.
