@amolkhatri
Does <aichat-config-dir>/functions/functions.json exist?

If not, add tools.txt and run argc build. ( see more details at https://github.com/sigoden/llm-functions)

Worked. Thanks.

However, I think ReadMe.md should specify that user needs to add function_calling: true in config.yml for enabling function calling.
