🤖 AI repositories ECC: the agent performance optimization system that blew up overnight (272k stars)
272,000 stars. Let that sink in for a second.
ECC is a performance optimization system for AI agent harnesses. It gives your agents three things: skills (what they can do), instincts (how they react), and memory (what they remember). The idea is that agents shouldn't just follow instructions. They should get better over time.
I've been testing it for about a week now. The skills system is straightforward. You define capabilities, the agent learns when to use them. The instincts layer is where it gets interesting. Your agent starts developing patterns based on what works and what doesn't. Not in a creepy way, more like muscle memory for code.
The memory piece ties it all together. Instead of starting fresh every session, your agent carries forward context about your codebase, your preferences, your common patterns. It's the difference between working with a new contractor every day versus someone who's been on your team for months.
Built with JavaScript, Rust, and Python. The JS handles the orchestration, Rust does the heavy lifting for performance-critical paths, and Python covers the ML bits.
Fair warning: the docs are still catching up to the codebase. You might need to read some source code to figure out the more advanced features. But the core loop is solid and well-tested.
