Superpowers packages a full spec-driven methodology into installable Claude Skills, enforcing brainstorming, planning, subagent-driven implementation, and strict TDD instead of leaving that structure up to you.
Most Claude Code SDD setups fail the same way: someone writes a solid specify-plan-implement skill once, uses it diligently for a week, then quietly drifts back to unstructured prompting the first time a deadline gets close. Nothing in a hand-rolled skill actually stops that. Superpowers is a direct answer to that discipline problem -- a skills package built by Jesse Vincent and the team at Prime Radiant that treats brainstorming, planning, subagent review, and red-green-refactor TDD as mandatory steps the agent checks before every task, not optional suggestions it can skip under pressure.
What makes it worth a dedicated look rather than a footnote is the install story. Superpowers ships plugin manifests for Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot CLI, Grok Build CLI, Kimi Code, OpenCode, Pi, Devin CLI, Factory Droid, and Hermes Agent, so the same methodology follows you across harnesses instead of living in one repo's .claude/skills/ folder. This guide covers what it actually is, how to install and verify it on the agent you use, what a first end-to-end run looks like, and where it fits next to other spec-driven development tooling.
