## GPTs vs. Installed Skills

| | Custom GPTs | Installed Skills |
|---|---|---|
| **Platform** | ChatGPT | Claude Code, Codex, Gemini CLI, Cursor, + 7 more |
| **Setup** | Click a link | `git clone` + install script |
| **Depth** | 1 skill per GPT | 177 skills, 16 agents, 3 personas |
| **Customization** | Use as-is | Full source, MIT licensed, extend freely |
| **Context** | Chat-based | Integrated into your codebase and workflow |
| **Best for** | Quick access, exploration | Daily development workflow |

The GPTs are a **preview** of what the full library offers. If you find a GPT useful, the installed skill version goes deeper — with access to your files, codebase, and project context.
