**This is a fork of [obra/superpowers](https://github.com/obra/superpowers) ported to [Google Antigravity 2.0](https://antigravity.google).\*\*

All upstream skills, workflows, and prompt templates are preserved. This fork adds native Antigravity 2.0 support: a plugin.json manifest, a comprehensive tool mapping reference (antigravity-tools.md), workspace isolation via invoke_subagent with Workspace: "branch", and a full test suite.

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.

Give your agent Superpowers: Antigravity 2.0, Antigravity IDE, Antigravity CLI, Claude Code, Codex CLI, Codex App, Factory Droid, Gemini CLI, OpenCode, Cursor, GitHub Copilot CLI.

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.

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

This is the primary target for this fork. Choose your platform below.

• Global plugin (available in all projects):

  git clone https://github.com/roundpilot/superpowers ~/.gemini/config/plugins/superpowers

• Workspace plugin (project-level only):

  git clone https://github.com/roundpilot/superpowers .agents/plugins/superpowers

• Update later:

  cd ~/.gemini/config/plugins/superpowers \&\& git pull

• Global plugin (available in all projects):

  git clone https://github.com/roundpilot/superpowers "$env:USERPROFILE\\.gemini\\config\\plugins\\superpowers"

• Workspace plugin (project-level only):

  git clone https://github.com/roundpilot/superpowers .agents\\plugins\\superpowers

• Update later:

  cd "$env:USERPROFILE\\.gemini\\config\\plugins\\superpowers"; git pull

If you run Antigravity inside WSL, use the Linux paths.

If you run the Windows Antigravity IDE but your workspace is in WSL, the plugin scope determines the location:

• Global plugin (available in all projects, installed on Windows side):

  Clone the repository directly to your Windows user profile path:

  git clone https://github.com/roundpilot/superpowers /mnt/c/Users/$USER/.gemini/config/plugins/superpowers

• Workspace plugin (project-level only, installed inside your WSL workspace):

  Clone (or symlink) the repository into the project-level plugins folder inside your WSL workspace:

  git clone https://github.com/roundpilot/superpowers /path/to/your/wsl/project/.agents/plugins/superpowers

  Activation

  Once installed, Superpowers skills are available via the /using-superpowers slash command in Antigravity 2.0 and Antigravity IDE. For the Antigravity CLI, the command is /superpowers:using-superpowers. Type the appropriate command at the start of a session to activate the skill system. (Note: If you have Antigravity open during install, restart the application to ensure the plugin is scanned and loaded). The agent will load the bootstrap and tool mapping, then brainstorming, TDD, subagent-driven-development, and all other skills will trigger automatically for the rest of the session.

  Verify Installation

1. Start a new Antigravity session

2. Type /using-superpowers (or /superpowers:using-superpowers if using the Antigravity CLI)

3. Say "Let's make a react todo list"

4. The brainstorming skill should trigger automatically

   Claude Code

   Superpowers is available via the official Claude plugin marketplace

   Official Marketplace

  The Basic Workflow

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

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

3. 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.

4. 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.

5. 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.

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

7. 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.

   See skills/writing-skills/SKILL.md for the complete guide.

   Updating

   Superpowers updates are somewhat coding-agent dependent, but are often automatic.
