ECC (Everything Claude Code)
Production config collection by an Anthropic hackathon winner, now renamed ECC. Its README lists 68 agents, 292 skills and 94 legacy commands, plus hooks, rules, memory and the AgentShield security scanner, installable as a Claude Code plugin. I keep its security-reviewer and build-error-resolver agents. For code review, I switched to the code-review skill.
Strengths
- 68 specialized agents: code-reviewer, security-reviewer, build-error-resolver
- 292 skills covering frontend, backend, DB, tests, deployment, full dev cycle
- Battle-tested production configs by an Anthropic hackathon winner
- Domain skills (tdd-workflow, frontend-patterns) usable one by one, without adopting the rest
Limitations
- Understanding what is active vs disabled takes exploration time
- Some agents less maintained than others, uneven quality by domain
Best for
- Claude Code devs wanting quality agents without writing them from scratch
- React/TypeScript projects needing strict TDD and automated code reviews
