Superpowers: the Most-Starred Claude Plugin That Makes Claude Plan, Test and Review Like a Senior Engineer
300,000+ GitHub stars, free and open source. What it changes about how Claude builds, how to install it in Claude Code in one command, a first prompt to try, and the catch
Superpowers is a free, open-source plugin (MIT, 300,000+ GitHub stars) made of skills that switch on by themselves. The moment Claude sees you're building something, it stops jumping straight into code: it asks what you actually want, writes a plan, then builds it task by task with tests and reviews.
Here's the workflow it adds, how to install it, a prompt to start with, and the catch.
What changes when it's on
- Brainstorming: Claude asks questions until it understands what you want, then plays it back in short chunks.
- Planning: the work is split into tasks of 2-5 minutes, each with exact files, code and a way to check it.
- Building: each task goes to a fresh subagent, with a review after each one (or inline, the cheaper option).
- Tests first: a failing test is written and watched fail before any code, then the code makes it pass.
- Code review between tasks: critical issues block progress until they're fixed.
- Finishing: it checks the tests and asks whether to merge, open a PR, keep or discard the branch.
