Curated Claude Code plugin marketplace

What it solves

This project provides a curated collection of plugins for Claude Code, allowing users to extend the AI's capabilities with specialized skills, productivity tools, and external data sources.

How it works

It acts as a marketplace catalog (marketplace.json) that Claude Code can add as a source to discover and install specific plugins. These plugins range from core productivity skills (like TDD and debugging) and writing guides (based on The Elements of Style), to development resources for creating more plugins, and MCP servers for private journaling with semantic search.

Who it’s for

Developers and users of Claude Code who want to enhance their AI assistant's workflow, add specialized knowledge bases, or integrate local memory systems.

Highlights

  • Core Skills Library: Includes over 20 battle-tested skills, including commands for brainstorming and plan execution.
  • Writing Guidance: Integrates a complete reference of The Elements of Style for clear and concise writing.
  • Development Toolkit: Provides documentation and workflows for building Claude Code plugins and MCP servers.
  • Private Journaling: Includes an MCP server that enables semantic search across private journals with local AI embeddings.
