Common Mistakes

Using a simple question as the prompt instead of a reasoning instruction.

The ReAct pattern starts with a prompt that encourages reasoning before acting, such as 'Think step-by-step and then act.'

💡 Hint

Common Mistakes

Using 'think' instead of 'act' to perform the action.

In the ReAct pattern, the agent acts on the input after reasoning, so the method to perform is 'act'.

💡 Hint

Common Mistakes

Using 'act' or 'reason' which are not the exact method names.

The correct method for the reasoning step in ReAct is 'think', which returns the agent's thought process.

💡 Hint

Common Mistakes

Swapping the order of 'think' and 'act'.

Using incorrect method names like 'run' or 'process'.

The loop first calls 'think' to reason, then 'act' to perform the action, repeating until done.

5fill in blank

hard

Fill all three blanks to store thoughts, actions, and results in a dictionary.

💡 Hint

Common Mistakes

Using 'respond' instead of 'observe' for the result.

Mixing up the order of methods.

The ReAct pattern uses 'think' for reasoning, 'act' for actions, and 'observe' to get results from the environment.
