### Answer
This is a known issue where agents sometimes verbalize tool calls, transitions, or internal logic out loud (e.g., saying "transitioning to close the conversation" or "end underscore call") . [(1) ](

How to address it:
The primary solution is
better prompting. You should:
1.
Explicitly instruct the agent in your prompt to never speak tool names, function calls, or transition states out loud
2.
Use a more capable model — using a better LLM tends to generate better responses and reduces this behavior
For example, add clear instructions like:
- "Never say tool names, function names, or internal states out loud"
- "Do not verbalize any technical operations or transitions"
This behavior is generally a prompting issue rather than a platform limitation.
