Everything Claude Code (ECC) is a complete performance optimization system for AI agent harnesses including Claude Code, Cursor, Codex, OpenCode, and GitHub Copilot. It provides production-ready agents, skills, hooks, rules, MCP configurations, memory persistence, continuous learning, and security scanning evolved over 10+ months of intensive development.

What It Does

ECC transforms AI coding agents from basic assistants into high-performance development systems through:

• 60+ specialized agents for TypeScript, Python, Go, Java, Kotlin, Rust, C++, and more
• 230+ reusable skills covering frameworks, patterns, and operational workflows
• Memory persistence hooks that save/load context across sessions automatically
• AgentShield security scanning for prompt injection, code injection, and credential leaks
• Token optimization through system prompt slimming and background process management
• Continuous learning that auto-extracts patterns into reusable skills
• 75+ legacy command shims for backward compatibility
• Cross-harness support with consistent behavior across tools
