ECC (Everything Claude Code)
Production config collection by an Anthropic hackathon winner, now renamed ECC. Its README lists 71 agents, 311 skills and 97 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
- 71 specialized agents: code-reviewer, security-reviewer, build-error-resolver
- 311 skills covering frontend, backend, DB, tests, deployment, full dev cycle
- MIT license, active repo (last push October 12, 2026) and the AgentShield security scanner to audit prompts, hooks, MCP and permissions
- Domain skills (tdd-workflow, frontend-patterns) usable one by one, without adopting the rest
Limitations
- Understanding what is active vs disabled takes exploration time
- The repo is moving to a skills-first surface: short commands like /tdd are retired into legacy-command-shims/, so an older tutorial may cite names that no longer exist
Best for
- Claude Code devs wanting quality agents without writing them from scratch
- React/TypeScript projects needing strict TDD and automated code reviews
