Superpowers

Overview

Superpowers is the most-starred agent skills framework on GitHub, offering a complete software development methodology for AI coding agents. Created by Jesse Vincent (obra) and backed by Prime Radiant, the project takes a distinctive position: instead of treating agent skills as isolated commands, Superpowers imposes a structured development lifecycle that guides agents from idea to shipped code. The framework has reached 276K+ stars — making it one of the most popular open-source projects of any kind — because it solves the fundamental problem of agent reliability: agents that jump straight into coding produce inconsistent results, while agents that follow a disciplined process produce reviewable, testable, mergeable work.

How It Works

Superpowers organizes development into seven sequential stages, each backed by a composable skill:

1. Brainstorming — Refines raw ideas through structured questions, then presents a validated design for approval before any code is written
2. Git Worktrees — Creates isolated development branches so agent work never contaminates the main branch
3. Planning — Decomposes work into small, precisely-specified tasks (2-5 minutes each) with explicit acceptance criteria
4. Execution — Dispatches subagents per task with two-stage review (the executing agent reviews its own work, then a separate review pass catches what it missed)
5. Test-Driven Development — Enforces RED-GREEN-REFACTOR cycles: write a failing test, make it pass, then clean up
6. Code Review — Checks compliance against the original plan and quality standards
7. Branch Completion — Handles merge decisions, PR creation, and cleanup

Skills trigger automatically based on the development context — no slash commands or manual activation required.

Use Cases

• Feature development — Full lifecycle from idea refinement through tested, reviewed, merged code
• Codebase refactoring — Plan-driven refactoring with safety nets (tests first, then change, then verify)
• Team onboarding — New team members get a structured methodology instead of ad-hoc agent usage
• Multi-agent orchestration — Subagent-driven development dispatches focused agents for each task while a coordinator manages the overall plan
• Quality enforcement — TDD and two-stage review catch bugs before they reach the main branch

Getting Started

Install Superpowers into your agent harness (Claude Code example):

# Clone the superpowers repo
git clone https://github.com/obra/superpowers.git

# Install skills into your Claude Code project
cp -r superpowers/skills/ .claude/skills/

Once installed, skills activate automatically. Start a conversation with your agent about a feature you want to build — Superpowers will guide the process from brainstorming through to a merged PR.
