world-model-harness makes it easy to go from agent traces to faithful replication of your production environment where your agents run.

Basically, an LLM pretends to be a virtual machine executing instructions. Based on GEPA and Qwen AgentWorld.

Just - clone, - `uv sync` - `uv run wmh build` and you'll get a wizard that will help you create your own world model from your traces.
