Superpowers is a composable skill framework and development methodology for coding agents. It prompts clarification before implementation, confirms a specification in readable chunks, and guides worktrees, plans, TDD, subagent execution, two-stage reviews, and branch finishing. It supports several agent harnesses, including Claude Code, Codex, Cursor, and OpenCode, but must be installed separately for each one.

gstack organizes product discovery, planning, design critique, code review, browser QA, security checks, release, and retrospectives as connected Claude Code slash commands. Each stage passes artifacts such as design documents and test plans to the next, giving founders and engineering teams a repeatable way to run one or many development sprints.

Equip coding agents with Vercel-maintained guidance for auditing deployment cost, performance, caching, and reliability; optimizing React, Next.js, and React Native code; reviewing web accessibility and UX; enforcing documentation standards; and creating claimable Vercel deployments. Once installed, the relevant skill becomes available when matching tasks are detected.

This collection packages hundreds of agent skills, plugins, personas, commands, and scripts across engineering, DevOps, security, marketing, compliance, research, leadership, and everyday productivity. The skills work natively or through conversion with Claude Code, Codex, Gemini CLI, Cursor, and other coding agents. It also documents orchestration patterns for chaining skills or handing work between specialist personas.
