Superpowers

Superpowers is an open-source software development methodology for coding agents, with more than 305,000 stars on GitHub, one of the most starred agent frameworks around. It is a set of composable skills plus starter instructions that teach a coding agent to slow down, understand what you actually want, and follow a disciplined workflow instead of jumping straight into writing code.

Overview

Superpowers changes how a coding agent behaves from the first message. It does not immediately produce code. Instead, it draws out your real goal through questions, plays its understanding back to you for correction, and turns the agreed design into a written document. From that design it builds a plan of bite-sized tasks, each with exact file paths, complete code, and verification steps. The agent then works through the plan with subagents, reviews its own work, and finishes the branch cleanly. The skills trigger automatically: once installed, your coding agent simply has Superpowers. It works with Claude Code, Codex, Cursor, Gemini CLI, OpenCode, and many other harnesses.

Key Features

• Brainstorming before building: The agent questions you until the goal is clear, then shows its understanding in short chunks so mistakes surface before any code exists.
• Written designs and bite-sized plans: Approved designs become plans with tasks small enough to verify individually.
• Subagent-driven development: Each task goes to a fresh subagent and is reviewed after completion, so the agent can work for hours without drifting from the plan.
• Test-driven development enforced: The workflow requires red-green-refactor discipline: a failing test first, minimal code second, and no code written before its test.
• Review between tasks: Code review checks work against the plan and reports issues by severity; critical issues block further progress.
• Isolated worktrees and clean finishes: Work happens on isolated branches with a verified test baseline, and a finishing workflow verifies tests, presents merge options, and cleans up.
• Broad harness support: Available through official marketplaces for the major coding agents, so one methodology follows you across tools.

💳 Pricing

Superpowers is free and open source. Optional commercial services, such as enterprise support, are offered separately.

Who Is It For

Superpowers is for developers who use AI coding agents on real projects and want structured, reviewable output instead of fast but careless code. If your agent misunderstands goals, skips tests, or drifts mid-task, this gives it the discipline to stay on plan.
