'foo'
Now let’s try it again with the max_iterations=2 keyword argument. It now stops nicely after a certain amount of iterations!
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True, max_iterations=2)
agent.run(adversarial_prompt)

 I need to use the Jester tool
Action: Jester
Action Input: foo
Observation: foo is not a valid tool, try another one.
 I should try Jester again
Action: Jester
Action Input: foo
Observation: foo is not a valid tool, try another one.

'Agent stopped due to max iterations.'
By default, the early stopping uses method force which just returns that constant string. Alternatively, you could specify method generate which then does one FINAL pass through the LLM to generate an output.
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True, max_iterations=2, early_stopping_method="generate")
agent.run(adversarial_prompt)
