Purpose and audience
Developers define allowed components and actions so generated interfaces follow their own catalog and schema.
How Jev fits
The playground's experimental composer uses typesafe-ai/jev to evaluate candidate components while building a UI specification.
Using the project
Define a catalog, then use experimental_composeSpec and experimental_createEvaluator or select Jev in the playground.
Scope and limits
The Jev path is experimental and unreleased, with source-build instructions; its playground evaluator reads JEV_AI_GATEWAY_API_KEY.
