What it does

JevHarness lets a language model write task-specific features, questions and control logic, with optional improvement from rewards and complete traces.

How Jev fits

Once frozen, the harness runs its code and Jev decisions without calling the authoring model for every action.

Getting started

Explore the archived Pokémon run locally with the website scripts, or install the skill and describe a task to build a harness.

Scope and limits

Reported Pokémon gains use the Eval set that selected the harness, not an unseen test. Frozen harnesses still need Jev when their graph contains Jev nodes.
