It is necessary to ensure that no hints with call examples in XML style get into the user's response.

I see many failed attempts,

Unexpected API Response: The language model did not provide any assistant messages. 
This may indicate an issue with the API or the model's output.

among which there are sometimes discussions that the instrument was called incorrectly and somehow mentions of XML instructions. I assume that not the entire request is cleared of XML instructions, and the model still tries to use XML.

citations from think process:

> Then get-library-docs. I need to use two tools. Provide XML tags. Use first resolve-library-id.
> So do resolve then get docs. Provide XML. 
> We provide <libraryName>[some_lib_name]</libraryName>.

this may confirm that the model is still trying to use xml to respond

[ERROR] You did not use a tool in your previous response! Please retry with a tool use.

# Reminder: Instructions for Tool Use

Tool uses are formatted using XML-style tags. The tool name itself becomes the XML tag name. Each parameter is enclosed within its own set of tags. Here's the structure:

<actual_tool_name>
<parameter1_name>value1</parameter1_name>
<parameter2_name>value2</parameter2_name>
...
</actual_tool_name>

For example, to use the attempt_completion tool:

<attempt_completion>
<result>
I have completed the task...
</result>
</attempt_completion>

Always use the actual tool name as the XML tag name for proper parsing and execution.

it also need to check that there are no hints mentioning xml format in the system prompt either

It's not impossible, but since the user's response isn't very structured, modifying it to avoid affecting other processes and minimize reliance on prompts is quite challenging.
First, I plan to adopt the tool_choice=“required” option available in the OpenAI API and see how it goes.

[irreg]

The section on Tool Use Formatting has already been marked for deletion.

[irreg]

Applying required seems to disable reasoning, so I will reconsider.

It's not impossible, but since the user's response isn't very structured,

I think it just need to add a config with custom search and replace rules, then user can specify a text (regexp rule) as in the links above and replace it with text without mentioning xml

[irreg]

I have modified it to enable additional replacements using regular expressions.

[R-omk]

enable additional replacements

Yes, I see it, thank you, but the example should be made more understandable, and it would be even better to create a real example that takes into account the links I provided earlier.

I also note that I have almost never encountered in practice the use of fields in objects as anything other than metadata, but as actual values (as far as configuration files are concerned).

It would also be better to use yaml, it is more readable and easier to work with in the case of complex regular expressions, fewer problems with escaping quotes.

[irreg]

I've changed the settings to YAML format. I'll fix the missing explanations the next time I have a free moment.
