Superpowers: NEW Spec Toolkit Ends Vibe Coding! 100x Better Than Vibe Coding (Full Tutorial)

Superpowers is a trending GitHub repo (74K+ stars) offering a fully autonomous AI development workflow that goes beyond spec-driven tools like OpenSpec or SpecKit. Rather than just converting ideas into specs, it guides AI coding agents through the entire engineering process: brainstorming, spec generation, implementation planning, and task execution via sub-agents. It integrates with Claude Code, Codex, Cursor, and other CLI tools via a plugin marketplace. The tutorial demonstrates building a landing page and a Rust-based Space Invaders game, showing how Superpowers reduces hallucination and produces higher-quality output compared to using Claude's chat interface alone.
