Your own personal AI assistant. Any OS. Any Platform. The lobster way. 🦞

ECC is an MIT-licensed system from affaan-m/ECC that installs into AI coding agent harnesses such as Claude Code, Codex, and several others, adding skills, specialized agents, persistent memory, and AgentShield security scanning around whatever large language model the harness already runs. GitHub lists the repo at 239,860 stars and 36,410 forks. The README positions it as developer productivity tooling for LLM agent development and agent performance tuning rather than a code generation tool itself, composing around whichever model the harness already calls.

The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
