Open Skill Market

skillmarket.cc — Discover, install, and manage AI agent skills for every major coding assistant.

---

An open marketplace for AI agent skills. This project collects skills from two sources:

1. PR Submissions: Users can submit skills directly to this repository via Pull Request
2. GitHub Crawler: Automatically discovers SKILL.md files across public GitHub repositories

All skills are indexed in a central skills.json registry.

What are Skills?

Skills are markdown files (SKILL.md) that teach AI agents how to perform specific tasks. They include:

• Name: Unique identifier for the skill
• Description: What the skill does and when to use it
• Instructions: Step-by-step guidance for the agent
• Examples: Concrete usage examples

Skills can be stored individually in repositories or as collections in a single repository.

Skills Registry Format

The registry uses a compact format to minimize file size. Shared repository info is extracted into a top-level repositories object, and derivable fields (displayName, author URL, avatar, downloadUrl, etc.) are omitted — clients reconstruct them at runtime.

When the total skill count exceeds the chunk size (default 2500), the output is split into multiple files by repository boundaries (e.g., skills.json + skills-1.json).
