**The performance optimization system for AI agent harnesses. From an Anthropic hackathon winner.**
Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, hooks, commands, rules, and MCP configurations evolved over 10+ months of intensive daily use building real products.
Works across **Claude Code**, **Codex**, **Cowork**, and other AI agent harnesses.
