Summary

Skillz provides an MCP server that transforms Claude-style skills (SKILL.md + resources) into callable tools for MCP clients (Codex, Copilot, Cursor). It offers a flexible, unified way to manage and execute custom agent functionalities, benefiting developers extending AI agents with reusable code and data.

How It Works

Skillz acts as an MCP server, discovering skills organized in directories or archives (.zip, .skill). Each skill requires a SKILL.md file with YAML front matter. Skillz exposes these instructions and bundled resources (scripts, datasets) as tools for MCP clients. This enables modular skill development and integration.

Quick Start & Requirements

Installation via uvx (uvx skillz@latest) or Docker (docker run -i --rm -v /path/to/skills:/skillz intellectronica/skillz /skillz). Configure MCP agent with skillz JSON settings, specifying command and skills path (default ~/.skillz). An optional Gemini CLI extension is available.

Highlighted Details

• Flexible Skill Organization: Supports nested directories and .zip/.skill archives, unlike Claude Code's flat layout.
• Resource Bundling: Skills can include arbitrary files like helper scripts or datasets, making them self-contained.
• CLI Utility: skillz --list-skills previews discovered skills.
• Transport Options: Supports stdio, http, and sse transports.

Maintenance & Community

The README provides no specific details on maintainers, community channels, or project roadmap.

Licensing & Compatibility

The project's license is not explicitly stated, a critical omission for adoption. Compatibility with commercial use or closed-source linking is undetermined.

Limitations & Caveats

Skillz is an "Experimental proof-of-concept," "Potentially unsafe," requiring skills to be treated as untrusted code run in isolation. Its flexible skill organization is not directly compatible with Claude Code's flat structure without adherence to specific layouts.
