How to install Superpowers Marketplace in Grok Build

grok plugin marketplace add obra/superpowers-marketplace

2. Install the plugin:

grok plugin install superpowers@obra/superpowers-marketplace --trust
✓ Install-checked in Grok Buildchecked Oct 19, 2026proof

Review before you trust it. --trust lets this plugin's hooks, MCP servers and scripts run code on your computer. It's a community repo that neither xAI nor GrokStacks has reviewed, so read its code first.

This repo's marketplace has 10 plugins; we checked elements-of-style, superpowers, superpowers-chrome. Install another the same way: grok plugin install <name>@obra/superpowers-marketplace --trust (names under 'What it contains'). Then start a new Grok session, or press r in /plugins, to load it.

Inside Grok Build: type /plugins, open the Marketplace tab, press a and add obra/superpowers-marketplace, then select superpowers and press i.

Command format: Grok Build's plugin guide

Runs a local MCP server (with npx, uvx or similar), so that tool needs to be installed, for example Node.js for npx.

What we checked: on Oct 19, 2026 it installed with grok 1.0.62 and Grok found 17 skills, 1 subagent. That's an install check only: we haven't run it in a live Grok session.

What it contains

Skills (17)

  • brainstorming — You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or planning anything new, in software or out of it (a talk, a business, a renovation).
  • diagnosing-superpowers — Use when a superpowers session went wrong and your human partner wants to know why — repeated work, ignored plans, stumbles, poor results, a skill that didn't fire, "it took too long", "why is it so expensive", "what is it doing" — or wants
  • dispatching-parallel-agents — Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
  • executing-plans — Use when executing an implementation plan in the current session as the implementer yourself — your human partner chose inline execution, or no subagent tool is available
  • finishing-a-development-branch — Use when implementation is complete, all tests pass, and you need to decide how to integrate the work
  • receiving-code-review — Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
  • requesting-code-review — Use when completing tasks, implementing major features, or before merging to verify work meets requirements
  • subagent-driven-development — Use when executing implementation plans with independent tasks in the current session
  • systematic-debugging — Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
  • test-driven-development — Use when implementing any feature or bugfix, before writing implementation code
  • using-git-worktrees — Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback
  • using-superpowers — Use when starting any conversation - establishes how to find and use skills, requiring skill invocation before ANY response including clarifying questions
  • verification-before-completion — Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
  • writing-plans — Use when you have a spec or requirements for a multi-step task, before touching code
  • writing-skills — Use when creating new skills, editing existing skills, or verifying skills work before deployment
  • browsing — Use when you need direct browser control - teaches Chrome DevTools Protocol for controlling existing browser sessions, multi-tab management, form automation, and content extraction via use_browser MCP tool
  • writing-clearly-and-concisely — Apply Strunk's timeless writing rules to ANY prose humans will read—documentation, commit messages, error messages, explanations, reports, or UI text. Makes your writing clearer, stronger, and more professional.
