       Show HN: Meta-agent: self-improving agent harnesses from live
       traces
        
       We built meta-agent: an open-source library that automatically and
       continuously improves agent harnesses from production traces.
       Point it at an existing agent, a stream of unlabeled production
       traces, and a small labeled holdout set.  An LLM judge scores
       unlabeled production traces as they stream.  A proposer reads
       failed traces and writes one targeted harness update at a time,
       such as changes to prompts, hooks, tools, or subagents. The update
       is kept only if it improves holdout accuracy.  On tau-bench v3
       airline, meta-agent improved holdout accuracy from 67% to 87%.  We
       open-sourced meta-agent. It currently supports Claude Agent SDK,
       with more frameworks coming soon.  Try it here:
