Interactivity

Let a task ask questions through a local terminal

cli=True exposes terminal interaction tools to a task. It is intended for local use where a person can answer prompts.

import marvin

name = marvin.run("Ask the user for their name", cli=True)

Set cli on the task or the run call, not on Agent:

import marvin
from pydantic import BaseModel

class Preferences(BaseModel):
    name: str
    interests: list[str]

interviewer = marvin.Agent(instructions="Ask one question at a time.")
preferences = marvin.run(
    "Ask for the user's name and interests",
    agents=[interviewer],
    result_type=Preferences,
    cli=True,
)

For an application with its own input loop, use say and a thread instead.
