Omgskills — Development skill for Claude Code

omgskills

A macOS menubar app for browsing and installing Claude, Codex, and agent skills from GitHub. Two independent parts: a Node.js scraper that builds the public skill library, and a Swift menubar app that reads bundled or remotely refreshed library data.

MCP server

Agents can search the omgskills library through the published read-only MCP server:

npm install -g omgskills-mcp

Add it to your MCP client:

{
  "mcpServers": {
    "omgskills": {
      "command": "omgskills-mcp"
    }
  }
}

The npm package uses hosted library data by default from:

https://omgskills.com/data/manifest.json

No local repo checkout is required for MCP users. Full tool docs live in [mcp/README.md](mcp/README.md).

Trust and safety

This repo is public so people can inspect how omgskills works before running it. It is source-available, not open source. You may read and audit the code, but you may not copy, redistribute, or repackage it without permission.

The app:

• reads public skill-library data bundled with the app or served from omgskills.com
• scans local Claude, Codex, and agent skill folders to show installed skills
• installs skills from public GitHub repositories only when you choose to install them
• uses Developer ID signing and Apple notarization for public macOS releases

Local crawl logs, browser traces, `.env` files, signing certificates, API tokens, and release credentials are intentionally not part of the public repo.

Security reports should follow [SECURITY.md](SECURITY.md).

Release first

For any public macOS download, use:

./scripts/release-mac.sh

Do not use `menubar/build.sh` for public distribution. It is dev-only and uses ad-hoc signing, which will trigger Gatekeeper warnings.

Required env vars:

• DEVELOPER_ID_APPLICATION
• ASC_PRIVATE_KEY_PATH
• ASC_KEY_ID
• ASC_ISSUER_ID
