Superpowers

Core skills library for Claude Code: TDD, debugging, collaboration patterns, and proven techniques

Superpowers

Jesse Vincent

Superpowers is a comprehensive skills framework that teaches Claude structured software development methodologies. It provides composable skills for test-driven development (TDD), systematic debugging, brainstorming, subagent-driven development with built-in code review, and the ability to author new skills. The plugin enforces disciplined practices like "red-green-refactor" TDD cycles where tests must fail before implementation, a four-phase debugging methodology that requires root cause investigation before any fixes, and Socratic brainstorming sessions that refine requirements before coding begins. How to use: Invoke skills with slash commands like /brainstorming to explore requirements and design before implementation, or /execute-plan to run batched implementation plans with review checkpoints. The framework includes a code-reviewer agent that evaluates implementations against plans, coding standards, and architectural principles. For debugging, the systematic methodology guides you through root cause investigation, pattern analysis, hypothesis testing, and implementation—with safeguards that trigger architectural review after three failed fix attempts. The writing-skills module teaches you to author and test new skills using TDD principles applied to documentation.

Code Review

Anthropic

Automates pull request code review using multiple specialized agents working in parallel. Five independent reviewers analyze your changes from different angles: CLAUDE.md compliance checking, bug detection, git history context analysis, previous PR comment review, and code comment verification. Each finding is scored on a 0-100 confidence scale, and only high-confidence issues (default threshold: 80) are posted as comments, dramatically reducing false positives and review noise. The plugin intelligently filters out PRs that don't need review—closed, draft, automated, or already-reviewed pull requests are automatically skipped. Comments include direct GitHub links with full SHA hashes and line number ranges for easy navigation to the exact code in question. How to use: Run /code-review on any PR branch to launch the full automated review. The system will analyze your changes, score potential issues, and post actionable feedback directly to GitHub. You can customize the confidence threshold or focus areas (security, performance, accessibility) by editing the command configuration.

context7

Upstash Context7 MCP server for up-to-date documentation lookup. Connects to Context7's hosted remote MCP server (https://mcp.context7.com/mcp) — no local Node.js or npx required — to pull version-specific documentation and code examples directly from source repositories into your LLM context. Authenticate with Context7 when prompted.

Context7

Upstash

Context7 is an MCP server that delivers up-to-date, version-specific documentation and code examples directly into your prompts. It solves a common problem with LLMs: outdated training data leading to hallucinated APIs and deprecated code patterns. Instead of relying on stale information, Context7 pulls current documentation straight from source repositories. The plugin provides two main tools: resolve-library-id for matching library names to Context7-compatible identifiers, and query-docs for retrieving documentation for specific libraries. You can even target specific versions by mentioning them in your prompt. How to use: Simply add "use context7" to any prompt where you need current documentation. For example: "Create a Next.js middleware that checks for a valid JWT in cookies. use context7" or "Configure a Cloudflare Worker script to cache JSON API responses. use context7". You can also specify exact libraries with "use library /supabase/supabase for API and docs".

GitHub

GitHub

The GitHub plugin connects Claude Code directly to GitHub's platform through the official GitHub MCP server. Manage repositories, issues, pull requests, and workflows without leaving your development environment. Browse code, analyze commits, and understand project structure across all your accessible repositories. Key capabilities include creating and updating issues and pull requests, reviewing code with AI assistance, monitoring GitHub Actions workflows, analyzing build failures, and managing releases. The plugin also provides security features like examining code scanning findings and reviewing Dependabot alerts. How to use: After connecting your GitHub account, interact naturally with your repositories. Try prompts like "Create an issue for the login bug in my-app repo", "Review the latest PR on my project", "Show me failed GitHub Actions runs", "Search for repositories about machine learning", or "List open issues assigned to me". The plugin handles authentication and API calls automatically.
