+  - While Elastic offers LLM connectors for many different vendors and models, not all LLMs are robust enough to be used with {{agent-builder}}.

+    or
+    ```
+    Error executing agent: No tool calls found in the response.

+- **{{agent-builder}} is not accessible**
+  - {{agent-builder}} was added in a private preview in September, 2025 for Serverless, and in 9.2.0 for Elastic Cloud.
+  - While in this preview stage, {{agent-builder}} is not enabled by default.
+  - To enable it, you must go to Stack Management -> Kibana -> Advanced Settings -> Elastic Agent Builder, and enable it.
