LangChain - Agents

Identify the error in this tool creation code:

def add_numbers(a, b):
    return a + b

from langchain.agents import Tool

add_tool = Tool(name='add', func=add_numbers, description='Adds two numbers')

result = add_tool.func(5)
print(result)

AMissing one argument when calling add_tool.func

BTool name must be uppercase

CDescription is too short

DFunction add_numbers should not return a value

Step-by-Step Solution

Solution:

Step 1: Check function parameters
add_numbers requires two arguments: a and b.
Step 2: Check function call
add_tool.func is called with only one argument (5), missing the second argument.
Final Answer:
Missing one argument when calling add_tool.func -> Option A
Quick Check:
Function needs 2 args, call has 1 = D [OK]

Quick Trick: Match function parameters with call arguments count [OK]

Common Mistakes:

MISTAKES

Ignoring argument count mismatch
Thinking tool name case matters
Assuming description length causes error
