Show HN: Meta-agent: self-improving agent harnesses from live traces (github.com) AI

Meta-agent is an open-source GitHub project that automates “harness” tuning for AI agents by iteratively running evaluations, collecting live traces, and generating improved harness/configuration candidates. The repository includes a quick-start workflow for running a baseline eval and then an optimization loop, plus example task definitions and configurations for tools like Claude Code. The project reports improved benchmark performance (e.g., tau-bench) and points to a WRITEUP.md for results and methodology.
