LangChain - Agents

Given this code snippet, what will be the output when the agent uses the tool?

def greet(name: str) -> str:
    return f"Hello, {name}!"

from langchain.agents import Tool

greet_tool = Tool(name='greet', func=greet, description='Greets a person')

result = greet_tool.func('Alice')
print(result)

A"greet Alice"

B"Hello, Alice!"

CError: Missing agent call

D"Hello!"

Step-by-Step Solution

Solution:

Step 1: Understand the greet function behavior
The greet function returns a string "Hello, {name}!" with the given name.
Step 2: Check how the tool is used
The tool calls greet with 'Alice', so it returns "Hello, Alice!" which is printed.
Final Answer:
"Hello, Alice!" -> Option B
Quick Check:
greet('Alice') = "Hello, Alice!" [OK]

Quick Trick: Tool calls function directly with given input [OK]

Common Mistakes:

MISTAKES

Thinking the tool prints 'greet Alice'
Assuming an error without agent context
Ignoring the name parameter in output
