Superpowers

Superpowers is a complete software development workflow for your coding agents, built on top of a set of composable "skills" and some initial instructions that make sure your agent uses them.

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

Note: Installation differs by platform. Claude Code has a built-in plugin system. Codex requires manual setup. OpenCode supports both automatic and manual installation.

$3

In Claude Code, register the marketplace first:

``bash
/plugin marketplace add obra/superpowers-marketplace
`

Then install the plugin from this marketplace:

`bash
/plugin install superpowers@superpowers-marketplace
`

$3

Check that commands appear:

`bash
/help
`

`


Should see:

/superpowers:brainstorm - Interactive design refinement

/superpowers:write-plan - Create implementation plan

/superpowers:execute-plan - Execute plan in batches

`

$3

Tell Codex:

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

Detailed docs: docs/README.codex.md

$3

Quick Install (npm):

Add to your opencode.json:

`json
{
"plugin": ["superpowers-opencode-fork-dev-test"]
}
`

Superpowers autoinstalls in the background. Note: Autoinstall works on Linux and macOS only.

Manual Installation:

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

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.

What's Inside

$3

Testing
- test-driven-development - RED-GREEN-REFACTOR cycle (includes testing anti-patterns reference)

Debugging
- systematic-debugging - 4-phase root cause process (includes root-cause-tracing, defense-in-depth, condition-based-waiting techniques)
- verification-before-completion - Ensure it's actually fixed

Collaboration
- brainstorming - Socratic design refinement
- writing-plans - Detailed implementation plans
- executing-plans - Batch execution with checkpoints
- dispatching-parallel-agents - Concurrent subagent workflows
- requesting-code-review - Pre-review checklist
- receiving-code-review - Responding to feedback
- using-git-worktrees - Parallel development branches
- finishing-a-development-branch - Merge/PR decision workflow
- subagent-driven-development - Fast iteration with two-stage review (spec compliance, then code quality)

Meta
- writing-skills - Create new skills following best practices (includes testing methodology)
- using-superpowers - Introduction to the skills system

Philosophy

- Test-Driven Development - Write tests first, always
- Systematic over ad-hoc - Process over guessing
- Complexity reduction - Simplicity as primary goal
- Evidence over claims - Verify before declaring success

Contributing

Skills live directly in this repository. To contribute:

1. Fork the repository
2. Create a branch for your skill
3. Follow the writing-skills skill for creating and testing new skills
4. Submit a PR

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

Updating

$3

Skills update automatically when you update the plugin:

`bash
/plugin update superpowers
`

$3

With the npm plugin, updates are handled automatically. Superpowers checks for updates on startup and pulls them in the background (unless disabled in config).

For manual installation, update by running:

`bash
cd ~/.config/opencode/superpowers
git pull
``

Then restart OpenCode.
