What happened

The model loop finished with no text: your ask() resolved to something with no text, or to an empty string. There is nothing to reconcile and nothing to paint, so the narrative is empty. Tool calls may still have run - this is about the final answer, not the intermediate steps.

The fix

Return a string, or an object with a text property, from ask(). A provider SDK usually needs its response unwrapped before it is returned.

The smallest fix

createAI(grid, { ask: async (prompt) => (await llm.complete(prompt)).text });
