A package manager for AI coding assistant skills

What it does

Antigravity Awesome Skills is a versioned repository of over 1,400 SKILL.md files—structured playbooks that tell Claude Code, Cursor, Codex CLI, Gemini CLI, and similar tools how to handle specific tasks like debugging, security audits, or MVP planning. An included npm installer drops these files into the directory each host expects, so the skills are discoverable by your agent without manual copy-pasting. The project also groups skills into domain-specific plugins and role-based bundles for users who want focus rather than a firehose of options.

The interesting bit

The clever part is treating prompt engineering like package management: instead of hoarding snippets in a notes app, the installer pulls a shallow-cloned, release-pinned catalog that behaves like a standard library for agents. It is a rare case where the boring logistics of file paths and directory structures matters more than the prompts themselves, because an uninstalled skill is just a markdown file you will never find.

Key highlights

• Ships 1,494+ SKILL.md playbooks covering development, testing, security, infrastructure, and product work.
• Supports Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, Kiro, OpenCode, and GitHub Copilot (with varying install paths).
• Offers specialized plugins for narrow domains—web apps, security, DevOps, QA, OSS maintenance—so you can install a focused subset.
• Uses shallow, release-pinned clones by default to keep first-time installs lightweight.
• Includes role-based bundles and ordered workflows that recommend which skills to chain together for common jobs.

Caveats

• GitHub Copilot lacks an automated installer; skills must be integrated manually unlike the other supported tools.
• The repository tip on main is not guaranteed to match the stable npm release, so the installer defaults to release-pinned clones.

Verdict

If you live in Claude Code or Cursor and are tired of rewriting the same system prompts, this is a practical standard library. If you prefer ad-hoc prompting or use Copilot exclusively, the friction may outweigh the benefit.
