@Shulyaka There seems to be an issue when converting the parameters with voluptuous_openapi if the intent does not have any parameters. OpenAI seems to expected properties to be present no matter what in the tool spec parameters (at least for GPT 3.5 turbo).

I added this to _format_tool to get it to work:

    if "properties" not in tool_spec["parameters"]:
        tool_spec["parameters"]["properties"] = {}

but I think this may be better suited for voluptuous_openapi. What do you think?

Yes, you are right, I will make the fix.
