From the makersREADME, read 18 Oct
ECC is an agent harness optimization system that gives coding agents a coordinated engineering process: planning before building, testing, independent review, memory, and reusable skills and workflows. It ships 71 agents, 311 skills, 97 command shims, hooks, rules, continuous learning, and AgentShield security scanning. It works best with Claude Code, has native Codex and Qoder plugin paths, and offers capability-limited adapters for Cursor, OpenCode, Gemini, and other harnesses.
