Getting started
For Claude Code, install from the official plugin marketplace:
/plugin install superpowers@claude-plugins-official
For other harnesses (Codex, Gemini CLI, Cursor, Copilot CLI), the repo has a one-line install for each. If you use more than one agent, install it separately for each.
That is the whole setup. After that, the skills just fire on their own.
The philosophy in one line
The project rests on four principles: test-driven development always, systematic process over ad-hoc guessing, simplicity as the primary goal, and evidence over claims. Verify before declaring success.
None of this is new advice. What is new is having an agent that enforces it instead of an agent that ignores it.
Is it useful?
Yes, with one honest caveat.
It is genuinely useful if you do non-trivial work and have been burned by an agent confidently shipping broken code. Because the agent follows a plan you already approved, it can run autonomously much longer without going off the rails. The structure is the value.
The caveat: it is deliberately slower for trivial work. If you just want to rename a variable or fix a typo, the brainstorm-then-spec-then-plan ceremony is overkill. Use Superpowers for features and real changes, not one-line fixes.
The takeaway
The model is rarely the bottleneck anymore. The bottleneck is that agents skip the boring, disciplined parts of engineering. Superpowers makes those parts mandatory. If your agent keeps producing plausible-looking garbage, this is the cheapest fix available: it is free, it installs in one command, and it changes nothing about how you work except the quality of the output.
