     Use `compat.supportsTools: false` only when the model or server reliably fails on tool schemas. It trades agent capability for stability.
+    `localModelLean` removes the browser, cron, and message tools from the agent surface, but it does not change Ollama's runtime context or thinking mode. Pair it with explicit `params.num_ctx` and `params.thinking: false` for small Qwen-style thinking models that loop or spend their response budget on hidden reasoning.
