✨ Magic Powers

magic-powers.pmai.space — A Claude Code plugin with cost-optimized model routing, 43 workflow skills, 11 specialized agents, and Stitch + Pencil design integration. Built for AI startups shipping fast with small teams. Also works with Cursor, Copilot, Aider, Windsurf, Gemini CLI, Codex, Kiro, and OpenCode.

Why Magic Powers?

Claude Code defaults to using the most expensive model for everything. Magic Powers routes tasks to the right model — ~75% cost reduction with no quality loss on routine tasks.

For actual API-level savings, combine with Claude Code Router or OpenRouter for 80-95% cost reduction.

Install

# Claude Code (recommended)
/plugin install github:your-username/magic-powers

# skills.sh (works with 43+ agents)
npx skills add kienbui1995/magic-powers

# All other tools — npx (auto-detects your tool)
npx magic-powers@latest

# Or with curl
curl -fsSL https://raw.githubusercontent.com/kienbui1995/magic-powers/main/scripts/get.sh | bash

The installer auto-detects Cursor, Windsurf, Kiro, Codex, OpenCode, Gemini CLI, and Claude Code from your environment.

Codex

git clone https://github.com/your-username/magic-powers.git
cd magic-powers && bash scripts/install.sh
# Select option 7 — Codex

Installs 11 agent skills to ~/.codex/skills/ and AGENTS.md to ~/.codex/AGENTS.md. Restart Codex after installing.

Invoke skills explicitly with $magic-<name> (e.g. $magic-architect, $magic-debugger), or just describe your task and Codex picks the right one.

Kiro

git clone https://github.com/your-username/magic-powers.git
cd magic-powers && bash scripts/install.sh
# Select option 8 — Kiro

Installs 11 agent steering files to .kiro/steering/. Each file uses inclusion: auto — Kiro automatically loads the right agent when your task matches. Also available as slash commands (e.g. /magic-architect, /magic-debugger).
