Is ChatAnthropic the only package that supports tool calling? Isn't it possible with ChatGithub?

[HotWesley]

Hello. I was trying to follow the Tool Calling example from the SHINY FOR PYTHON website.
Due to internal constraints, I need to use the ChatGithub package instead of ChatAnthropic.
So I only replaced the package and tried running the example as-is, but Tool Calling doesn't work.
What should I do?

client.py

import requests
from chatlas import ChatGithub

chat_client = ChatGithub(api_key="KEY", base_url="URL")

def get_current_weather(latitude: float, longitude: float):
    """Get the current temperature given a latitude and longitude."""

    lat_lng = f"latitude={latitude}&longitude={longitude}"
    url = f"https://api.open-meteo.com/v1/forecast?{lat_lng}&current=temperature_2m,wind_speed_10m&hourly=temperature_2m,relative_humidity_2m,wind_speed_10m"
    response = requests.get(url)
    json = response.json()
    return json["current"]

chat_client.register_tool(get_current_weather)

app.py

from view_agent.client import chat_client
from shiny.express import ui

chat = ui.Chat(id="chat")
chat.ui(messages=["Hello! How can I help you today?"])

@chat.on_user_submit
async def _(user_input: str):
    response = await chat_client.stream_async(
      user_input,
      content="all"
    )
    await chat.append_message_stream(response)

Yes, ChatGithub() supports tool calling. This minimal example works for me:

import os
import requests
from chatlas import ChatGithub

chat = ChatGithub(api_key=os.getenv("GITHUB_PAT"))

def get_current_weather(latitude: float, longitude: float):
    """Get the current temperature given a latitude and longitude."""

    lat_lng = f"latitude={latitude}&longitude={longitude}"
    url = f"https://api.open-meteo.com/v1/forecast?{lat_lng}&current=temperature_2m,wind_speed_10m&hourly=temperature_2m,relative_humidity_2m,wind_speed_10m"
    response = requests.get(url)
    json = response.json()
    return json["current"]


chat.register_tool(get_current_weather)

chat.chat("What is the current temperature in San Francisco?")

Could you try running that and letting me know what you get for output? What are you setting the base_url to? Are you changing the model?
