Claude Code
Everything Claude Code (ECC): an open-source layer of skills, instincts, persistent memory, hooks and security scanning that supercharges Claude Code, Codex, Cursor and other harnesses — 211k+ stars.
Why it's interesting
It's the most talked-about project in the Claude Code ecosystem: it distills 10+ months of daily use into a reusable system. I find it instructive even just to read, to learn how to structure skills, hooks and rules.
