Superpowers: An Agentic Skills Framework for AI Coding Workflows

Superpowers is a complete software development methodology for coding agents, built on composable skills and initial instructions. It emphasizes test-driven development, design-first approach, and subagent-driven iteration, supporting multiple coding assistants like Claude Code, Codex CLI, and Gemini CLI.

Key points

Superpowers provides a skills library including TDD, systematic debugging, collaboration planning, enabling agents to work autonomously for hours.
The workflow starts with brainstorming specifications, followed by design approval, implementation plan generation, and subagent-driven execution with two-stage review.
Supports installation on multiple platforms such as Claude Code, Codex CLI, Gemini CLI, etc., with skills triggered automatically before any task.

Why it matters

This matters because superpowers provides a skills library including TDD, systematic debugging, collaboration planning, enabling agents to work autonomously for hours.

Technical impact

May affect model selection, inference cost, product capability, and evaluation benchmarks.

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.

Quickstart

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

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 Claude to be able 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.

Sponsorship

If Superpowers has helped you do stuff that makes money and you are so inclined, I'd greatly appreciate it if you'd consider sponsoring my opensource work.

Thanks!

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.

/plugin marketplace add obra/superpowers-marketplace

Install the plugin from this marketplace:

/plugin install superpowers@superpowers-marketplace

Codex CLI

Superpowers is available via the official Codex plugin marketplace.

Open the plugin search interface:

/plugins

Search for Superpowers:

superpowers

Select Install Plugin.

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.

Factory Droid

droid plugin marketplace add https://github.com/obra/superpowers

Install the plugin:

droid plugin install superpowers@superpowers

Gemini CLI

Install the extension:

gemini extensions install https://github.com/obra/superpowers

Update later:

gemini extensions update superpowers

OpenCode

OpenCode uses its own plugin install; install Superpowers separately even if you already use it in another harness.

Tell OpenCode:

Fetch and follow instructions from https://raw.githubusercontent.com/obra/superpowers/refs/heads/main/.opencode/INSTALL.md

Detailed docs: docs/README.opencode.md

Cursor

In Cursor Agent chat, install from marketplace:

/add-plugin superpowers

Or search for "superpowers" in the plugin marketplace.

GitHub Copilot CLI

copilot plugin marketplace add obra/superpowers-marketplace

Install the plugin:

copilot plugin install superpowers@superpowers-marketplace

The Basic Workflow

brainstorming - Activates before writing code. Refines rough ideas through questions, explores alternatives, presents design in sections for validation. Saves design document.

using-git-worktrees - Activates after design approval. Creates isolated workspace on new branch, runs project setup, verifies clean test baseline.

writing-plans - Activates with approved design. Breaks work into bite-sized tasks (2-5 minutes each). Every task has exact file paths, complete code, verification steps.

subagent-driven-development or executing-plans - Activates with plan. Dispatches fresh subagent per task with two-stage review (spec compliance, then code quality), or executes in batches with human checkpoints.

test-driven-development - Activates during implementation. Enforces RED-GREEN-REFACTOR: write failing test, watch it fail, write minimal code, watch it pass, commit. Deletes code written before tests.

requesting-code-review - Activates between tasks. Reviews against plan, reports issues by severity. Critical issues block progress.

finishing-a-development-branch - Activates when tasks complete. Verifies tests, presents options (merge/PR/keep/discard), cleans up worktree.

The agent checks for relevant skills before any task. Mandatory workflows, not suggestions.

What's Inside

Skills Library
