feat(llm): list available tools in unknown-function error output#6085
Merged
Conversation
When a model hallucinates a tool name, the error fed back to it only said "Unknown function: <name>", giving it nothing to correct with. Include the available tool names in the error output so the model can retry with a valid tool on the next turn.

When a model hallucinates a tool name, the error fed back to it is just
Unknown function: <name>, which gives it nothing to self-correct with — smaller models in particular tend to retry the same invalid name.Include the available tool names in the error output (both in
execute_function_calland the voice generation path) so the model can pick a valid tool on the next attempt.
