Stop copy-pasting prompts: give your AI agent installable skills (quickstart OSM)

TL;DR

AI agents like Claude Code and Codex can load skills — markdown files that teach them expertise — but finding good ones means digging through scattered repos.
OpenSkill.md (OSM) is an open-source registry + CLI: search, install, and score agent capabilities in one command.
The whole loop: npm i -g @openskillmd/osm → osm search → osm add. Done in under a minute.

The problem

If you use an AI coding agent daily, you have probably built a private stash of prompts: your testing conventions, your commit style, your framework quirks. And you paste them. Again. And again.

Skills fixed part of this. A skill is just a SKILL.md file — instructions your agent loads automatically when the task matches. Write once, reuse forever. The ecosystem took off fast: Anthropic ships official skills, and hundreds of community skills live on GitHub.

Which created the next problem: discovery. Skills are scattered across repos with no central index, no search, and no way to tell a great skill from a broken one before installing it.

That is exactly the gap package managers filled for code. So we built one for agent capabilities.

The quickstart

1. Install the CLI

npm i -g @openskillmd/osm

2. Search the registry

osm search testing

You get a ranked list of skills matching your query, with quality scores.

3. Inspect before you install

osm info <slug>

For any skill backed by a source repo, the output hands you the exact install command, ready to paste.

4. Install it

osm add anthropics/skills@frontend-design

osm add pulls the skill straight from its source repo and drops it where your agent expects it — it is agent-aware, so Claude Code, Codex and Cursor each get the right location. Installing one skill from a multi-skill repo? The @skill suffix handles it.

5. Check what's installed

osm list

That's it. Your agent picks the skill up on its next run. No config, no copy-paste.

Going further

Let your agent shop for itself — osm router install drops a meta-skill that teaches your agent to discover and install skills on demand from the registry.
Score your own skills — osm score SKILL.md evaluates a local skill for quality before you share it.
Beyond skills — the registry also covers blueprints (output quality enforcement), MCP servers (osm mcp setup prints the config for Claude/Cursor), and full plugin bundles (osm plugin install).

What's next

Authenticated publishing (osm login / osm publish) is on the roadmap — we are building this in public, and the whole thing is MIT-licensed.
