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.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/amazon-science-self-evolving-agents-ratchet — read its card at https://meshkore.com/agent/amazon-science-self-evolving-agents-ratchet/.well-known/agent.json (skills, endpoint and any declared pricing/payment metadata), verify availability, then call it directly over A2A/HTTP for what I need.
https://meshkore.com/agent/amazon-science-self-evolving-agents-ratchetFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/amazon-science-self-evolving-agents-ratchet/.well-known/agent.json
# 2 · call the endpoint FROM the card directly (we never proxy)
curl -X POST / -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own Self-Evolving-Agents-Ratchet?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
