ECC packages an engineering loop around coding agents

ECC is an open-source harness layer that packages planning, tests, review, verification, memory and security checks around coding agents across Claude Code, Codex and other tools. Why it matters: Your coding agent is not the workflow. The harness is. Reusable gates and fresh-context review make agent output more repeatable than adding another prompt, model or MCP server.

Try this: Audit one high-frequency agent workflow. Add one deterministic verifier and one review handoff before you add another model, agent or MCP server.
