About

ECC is an agent harness operating system: portable skills, instincts, memory, security rules, and research-first workflows that work across Claude Code, Codex, OpenCode, and Cursor. Instead of rebuilding your agent setup for every tool, you define it once in ECC and carry it with you. It is MIT open source and one of the fastest-growing agent repos, which makes it a natural starting layer for anyone serious about agent workflows.
