Superpowers Plugin

A Claude Code plugin that orchestrates Claude + Codex CLI into a structured 5-phase development workflow.

Phases

Phase 1: Design / Brainstorm     — Claude investigates codebase, drives design
Phase 2: Design Review            — Claude vs Codex adversarial battle
Phase 3: Implementation           — Codex handles backend, Claude handles frontend
Phase 4: Testing                  — Verify on device/emulator/browser
Phase 5: Code Simplification      — /simplify runs 3 parallel review agents

Why

• Phase 2 (Battle) catches design flaws that a single AI misses
• Phase 5 (/simplify) catches 3-5 code quality issues per feature branch that would otherwise surface during code review
• Division of labor plays to each AI's strengths: Codex for backend/logic, Claude for frontend/UI
