The best tools aren't the ones that do the work for us, but the ones that help us do it with more structure, better quality, and fewer headaches.

If you've been using Claude to develop software, manage projects, or automate tasks, you've probably noticed a pattern: sometimes the AI jumps straight into writing code without thinking about the consequences, ignores tests, or loses the thread on big projects.

That's where Superpowers (obra/superpowers) comes in: the agentic skills framework that's changing how we interact with language models. In this guide I'll explain what it is, why you need it, and how to install it in Claude Cowork from the Official Claude Marketplace or directly from the official GitHub repository.

What Superpowers is and why it changes the game

Superpowers isn't just a saved prompt. It's a complete software development methodology and a skills framework designed specifically for coding agents.

Its philosophy rests on three pillars:

1. Test-driven development (TDD): write the tests first, always.
2. Systematic over improvised: clear processes instead of guessing.
3. Evidence over claims: verify before declaring that something is "done."

When you install Superpowers, Claude stops being a simple assistant that answers fast. It becomes a disciplined engineer that plans before coding, writes tests first, and reviews its own work in two stages before handing you the final result. Best of all: all of this runs automatically in the background.

How to install Superpowers in Claude Cowork

If you use Claude Code in the terminal rather than Cowork, follow the guide to installing Superpowers in Claude Code.

Claude Cowork is Anthropic's desktop agent built for multi-step tasks and collaborative work. You have two paths to install it:

Option A: from the Official Claude Marketplace (recommended)

It's the fastest, safest, and easiest path to keep updated.

1. Open your terminal or the Claude Cowork chat interface.
2. Install the plugin directly from the official marketplace:

/plugin install superpowers

Or, if you want access to the complementary plugins in the Superpowers ecosystem:

/plugin marketplace add obra/superpowers-marketplace
/plugin install superpowers@superpowers-marketplace

You can also browse the marketplace by visiting the Official Claude Marketplace or by looking for verified plugins directly from your Claude client.

Option B: from the official GitHub repository

If you'd rather have the code locally or follow the development branch:

1. Open your terminal.
2. Clone the repository:

git clone https://github.com/obra/superpowers.git ~/.claude/plugins/superpowers

3. Restart your Claude Cowork session.

The workflow: what happens when you use Superpowers

Once installed, your AI agent has its "superpowers." The flow splits into 7 automatic phases:

1. Brainstorming (/brainstorm): refines your idea with questions and validation.
2. Git worktrees: an isolated workspace on a fresh branch.
3. Planning (/write-plan): breaks the work into 2-5 minute tasks.
4. Subagents (/execute-plan): delegation with built-in review.
5. TDD: the red-green-refactor cycle.
6. Code review: review against the original plan.
7. Finish: merge, PR, or discard with cleanup.

Pro tips to get the most out of it

• Don't skip the brainstorming. Always use /brainstorm [your idea].
• Let the subagents work. Trust the automatic delegation.
• Combine it with MCP. Connect databases, documentation, or design tools.

If connecting more tools ends up meaning new licenses or subscriptions to pay, at Eneba you get 5% off with my link. It's an affiliate link: it costs you less and it helps me keep the blog running. And if it's for your team, here I explain how to buy cheap software licenses on Eneba. The 5% applies with the code CreaCosas at checkout, as long as you arrive through the link.

Frequently asked questions

Is Superpowers paid?

No. It's an open source project (obra/superpowers) that installs for free from the official marketplace or from GitHub. You can review the code before using it.

Does it only work with Claude Cowork?

Superpowers is built for agents that use Anthropic's skills and plugins format. This guide focuses on Claude Cowork, but the same skill can be installed on other Claude clients that support the marketplace.

Does it force me to write tests first?

It doesn't force you, but that's its biggest advantage. Test-driven development makes the AI review its own work and end up with fewer bugs and more maintainable code. On big projects, that difference really shows.

Conclusion

Installing Superpowers in Claude Cowork is the 5-minute productivity upgrade that will have the biggest impact on your workflow. It turns the AI from an "unpredictable code generator" into a methodical, testable, reliable teammate.
