ECC is a free, open-source plugin that turns Claude Code into a whole engineering team: agents that plan, build, review, secure and test your code, plus hundreds of skills they use along the way. One developer built it in ten months and it is one of the most-starred Claude Code projects on GitHub.
Hiring the same five roles (architect, engineer, security, QA, reviewer) costs about $627,000 a year at US median pay. Here is how to set it up and the four prompts from the video.
What you get
- 71 specialist agents for planning, architecture, code review, security, build repair and testing.
- 314 skills: test-driven development, security review, backend and frontend patterns, docs and more.
- AgentShield, a scanner that checks your prompts, hooks, settings and secrets for holes.
- Works best in Claude Code; also installs in Codex, with lighter adapters for Cursor and others.
