Superpowers

Superpowers is a library of composable skills plus a small set of bootstrap instructions that make a coding agent actually use them. Instead of jumping straight into code, the agent first draws out what you're trying to build, shows the spec back in short chunks, writes an implementation plan, and then works through it with subagents that implement and review each task. Skills cover test-driven development, systematic debugging, verification before declaring work done, brainstorming and plan writing, and they trigger automatically.

It installs into Claude Code (via the official plugin marketplace), Codex, Cursor, Gemini CLI, GitHub Copilot CLI, OpenCode and many other agents. It's a fit for developers who want their agent to follow a disciplined engineering process by default rather than re-prompting for it every session.
