OSM - Open Skills Manager

OSM (Open Skills Manager) is an open-source registry and command-line tool for managing reusable skills for AI agents, following the agentskills.io specification. It hosts over 52,000 skills that agents and developers can search, install, and publish. OSM functions like a package manager (similar to npm) but specifically designed for AI agent capabilities, making it easy to extend agents with pre-built, versioned skill packages.

• Skill Registry — Browse and search 52,000+ published agent skills by name or description using osm search <query>.
• CLI Installation — Install OSM with a single curl command (curl -fsSL https://www.osmagent.com/install.sh | bash) requiring only Node.js v18+.
• Install & Manage Skills — Use osm install <skill>, osm update, and osm uninstall to manage skills locally, similar to a traditional package manager.
• Skill Publishing — Scaffold a new skill with osm create <skill-name>, edit the generated SKILL.md manifest and README.md, then publish with osm publish.
• SKILL.md Manifest Format — Each skill uses a Markdown file with YAML front-matter specifying name, version, description, and AI model compatibility (e.g., claude-3, gpt-4).
• Agent-Friendly Interface — Provides a dedicated /agent endpoint so AI agents can interact with the registry programmatically.
• Authentication — Supports account creation (osm signup), login/logout, and local token storage at ~/.osm/auth.json for secure publishing.
• Structured Skill Packages — Skills follow a standard folder structure including a manifest, README, setup scripts, API references, and optional assets, with a max package size of 1 MB.
• Open Source — Fully open source on GitHub, enabling community contributions and transparency.
• Discovery Feed — OSM Discovery surface highlights recently published and most-downloaded skills for easy exploration.
