ECC

ECC is an operating layer that sits across coding agents rather than inside one: shared skills the agents can use, hooks that run around their actions, a plan canvas for multi-step work, memory, and a security policy layer. It installs into Claude Code, Codex and others through a guided setup.

The category exists because of a new kind of duplication. A team that uses several coding agents has, in practice, several separate configurations of the same intentions — the same house rules written out again, the same helper scripts rebuilt, the same review checklist restated — and none of them knows what the others did. Putting that layer outside any single agent is the right shape for the problem, and it is also where the risk sits: this layer sees every prompt your team sends and can run code around every agent action. That is a large amount of trust in a tool that is not the model vendor, and it deserves the same review as any other thing in that position.
