Conditional edge from chatbot to END

[continentalGT]

How does the graph knows to add conditional edge from chatbot. in ss

and what is tool node

the tools_condition is basically the check that says if chatbot output is tool call, go to tools. if not, go to END. Thats why it only needs start -> chatbot and tools -> chatbot. you can think of it like tools_condition is an extra node that chatbot is connected to, but it routes to the appropriate node based on what the chatbot sends to it. tools node is just the thing that processes tool call messages to call the tool and return the results.
