Self-Evolving-Agents-Ratchet

Reference implementation of Ratchet: a minimal hygiene recipe for self-evolving LLM agents (arXiv:2605.22148)

Ratchet is a self-evolving single-agent system that turns its own failures into a governed library of natural-language skills, so a frozen LLM keeps improving on code and patch benchmarks without weight updates. It is the reference implementation of Ratchet: A Minimal Hygiene Recipe for Self-Evolving LLM Agents, whose contribution is the library's lifecycle discipline: skills are synthesised from clustered failures, injected as prompt guidance, and retired once they stop helping, under a bound that keeps the library from drifting.
