ECC
by affaan-m
ECC is a bundle of agents, skills, rules, hooks and memory that you add to AI coding assistants such as Claude Code and Codex. It gives the assistant a set process of planning, testing, reviewing and remembering, so you don't have to rebuild that in every prompt.

What you can do with it
- Install a ready-made set of planning, review and build-repair agents into Claude Code or Codex
- Use hundreds of reusable skills to enforce test-driven development and code review
- Scan your agent setup for security problems with the AgentShield scanner
Make money with it
A freelance developer could use it to deliver tested, reviewed client projects faster, and so take on more paid work.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Make AI-assisted coding more consistent and better tested, which cuts time spent fixing agent mistakes
- Let a solo developer or small team get review and security checks without hiring extra reviewers
Can you use it commercially?
Free to use, change and sell, including in paid products. Keep the copyright notice.
Not legal advice. Read the project's licence file before building a product on it.
Getting it running
Install it as the ecc@ecc plugin in Claude Code using the guided setup or native plugin commands, or through the ecc-universal npm package.
Follow the official instructions in the project README.
Things to check
- Needs an AI coding assistant, which usually means a paid subscription or API keys
- Feature support varies by platform, and Claude Code is the best supported
- Very large collection of skills and agents, so it may be more than you need
- Only install from the official sources, as unofficial mirrors may contain malware
- Hosted ECC Pro for private repos is a paid add-on
