Detailed Introduction

Superpowers is an open-source skills library and development workflow for coding agents. Before a coding agent writes code, Superpowers guides design refinement, presents designs in digestible chunks for approval, then produces an executable implementation plan. It then drives subagent-driven development with two-stage review to ensure implementations follow the plan. The project emphasizes test-driven development (RED-GREEN-REFACTOR) and process-driven simplicity to make autonomous coding predictable and verifiable.

Main Features

  • Triggered skills (brainstorming, writing plans, executing plans, requesting code review) that activate at the right stages.
  • Enforced test-driven workflow to ensure changes are covered by failing tests before implementation.
  • Subagent-driven parallel task execution with two-stage reviews (spec compliance, code quality).
  • Built-in git worktree workflows, tmux monitoring, and plugin marketplace installation (e.g., Claude Code plugin).
  • Clear contributor guides for adding new skills under the skills/ directory.

Use Cases

  • Hand off coding tasks to agents while maintaining design reviewability and auditability.
  • Rapidly build prototypes with strong test coverage using Superpowers’ TDD-first workflow.
  • Break work into small tasks and execute them in parallel via subagents to accelerate delivery.
  • Reuse skills across agent platforms such as Claude Code, Codex, and OpenCode.

Technical Characteristics

  • Script- and config-driven skills library suitable for multiple agent platforms.
  • Supports Claude Code plugin marketplace installation and includes docs for other platforms.
  • Emphasizes testability and verifiability with example tests and documentation in the repo.
  • Lightweight, modular design for minimal-friction integration into existing automation pipelines.
