Superpowers

Superpowers is a complete software development methodology for your coding agents, built on top of a set of composable skills and some initial instructions that make sure your agent uses them.

We're Hiring!

We're hiring someone to help out full time with Superpowers community and code work. You can read about the job at https://primeradiant.com/jobs/superpowers-community-engineer/ If this sounds like someone you know, definitely send them our way.

Quickstart

Give your agent Superpowers: Claude Code, Antigravity, Codex App, Codex CLI, Cursor, Factory Droid, GitHub Copilot CLI, Kimi Code, OpenCode, Pi.

How it works

It starts from the moment you fire up your coding agent. As soon as it sees that you're building something, it doesn't just jump into trying to write code. Instead, it steps back and asks you what you're really trying to do.

Once it's teased a spec out of the conversation, it shows it to you in chunks short enough to actually read and digest.

After you've signed off on the design, your agent puts together an implementation plan that's clear enough for an enthusiastic junior engineer with poor taste, no judgement, no project context, and an aversion to testing to follow. It emphasizes true red/green TDD, YAGNI (You Aren't Gonna Need It), and DRY.

Next up, once you say "go", it launches a subagent-driven-development process, having agents work through each engineering task, inspecting and reviewing their work, and continuing forward. It's not uncommon for your agent to work autonomously for a couple hours at a time without deviating from the plan you put together.

There's a bunch more to it, but that's the core of the system. And because the skills trigger automatically, you don't need to do anything special. Your coding agent just has Superpowers.

Installation

Installation differs by harness. If you use more than one, install Superpowers separately for each one.

Claude Code

Superpowers is available via the official Claude plugin marketplace

Official Marketplace

• Install the plugin from Anthropic's official marketplace:

  /plugin install superpowers@claude-plugins-official
  

Superpowers Marketplace

The Superpowers marketplace provides Superpowers and some other related plugins for Claude Code.

• Register the marketplace:

  /plugin marketplace add obra/superpowers-marketplace
  

• Install the plugin from this marketplace:

  /plugin install superpowers@superpowers-marketplace
  

Antigravity

Install Superpowers as a plugin from this repository:

agy plugin install https://github.com/obra/superpowers

Antigravity runs the plugin's session-start hook, so Superpowers is active from the first message. Reinstall with the same command to update.

Codex App

Superpowers is available via the official Codex plugin marketplace.

• In the Codex app, click on Plugins in the sidebar.
• You should see Superpowers in the Coding section.
• Click the + next to Superpowers and follow the prompts.
