Claude Code ships as a general-purpose but undifferentiated AI coding assistant. Developers who rely on it out of the box quickly discover the absence of structure: no specialized agents, no built-in security scanning, no enforced rules, and no repeatable workflows. Everything Claude Code (ECC) addresses this gap directly. It is an open-source operator system that layers 60 specialized agents, 232 skills, 75 slash commands, and a 1,282-test security scanner on top of Claude Code, transforming ad-hoc AI prompting into an auditable, extensible engineering platform. And it is not locked to a single harness. ECC supports Codex CLI, Cursor, and OpenCode, making it a cross-harness framework designed to enforce consistent engineering standards across multiple AI coding tools. As of this writing, readers should confirm the ECC package name, repository URL, and current version from the project's official documentation before proceeding.…
