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.

Fork Note: This is a compatibility-focused fork of obra/superpowers with production-tested improvements including mechanical enforcement and safety gates. All existing workflows and commands work unchanged. See what's different →

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 and OpenCode require manual setup.

Claude Code (via Plugin Marketplace)

In Claude Code, register the marketplace first:

/plugin marketplace add obra/superpowers-marketplace

Then install the plugin from this marketplace:

/plugin install superpowers@superpowers-marketplace

Verify Installation

Check that commands appear:

/help

# Should see:
# /superpowers-fork:brainstorm - Interactive design refinement
# /superpowers-fork:write-plan - Create implementation plan
# /superpowers-fork:execute-plan - Execute plan in batches

Codex

Tell Codex:

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

Skills Library

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

Release Workflow

Version management uses Commitizen with conventional commits:

Commit format:

• feat: - New features (minor version bump)
• fix: - Bug fixes (patch version bump)
• docs: - Documentation only
• chore: - Maintenance tasks
• BREAKING CHANGE: in commit body - Major version bump

Release process:

1. Make conventional commits as you work:

   git commit -m "feat: add new skill"
   git commit -m "fix: correct script path"

2. When ready to release:

   ./scripts/release.sh

3. Script will:

   • Check for clean git state
   • Analyze commits since last tag
   • Preview version bump (major/minor/patch)
   • Update .claude-plugin/plugin.json
   • Generate CHANGELOG.md
   • Create annotated git tag
   • Show push instructions

4. Push to GitHub:

   git push --follow-tags

5. Marketplace updates automatically:

   • Company marketplace reads plugin.json from GitHub
   • No manual marketplace sync needed
   • Users install: superpowers-fork@renaissance-marketplace

Tools:

• Commitizen: Version bumping and changelog generation
• Pre-commit: Conventional commit validation

Installation:

pipx install commitizen pre-commit

Updating

Skills update automatically when you update the plugin:

/plugin update superpowers
