The core request is for improved documentation (demo or README.md) on how to integrate various Large Language Model (LLM) providers, specifically mentioning `openrouter`. This indicates a pain point in the onboarding and extensibility workflow for `OpenHarness`.

This issue identifies a critical documentation gap impacting developer adoption for `OpenHarness`. The request for clear instructions on integrating diverse LLM providers, such as `openrouter`, directly challenges the product's "multi-provider support" positioning. Without accessible, practical guidance, developers face significant friction in leveraging the platform's core extensibility. This directly impedes onboarding and reduces perceived value, regardless of underlying technical capability. Effective documentation is not merely a convenience; it is a fundamental component of product usability and market penetration, especially for developer tools aiming for broad integration.
