Human Input on Execution

Human inputs is important in many agent execution use cases, humans are AGI so they can can be prompted to step in and provide extra details ins necessary. Using it with crewAI is pretty straightforward and you can do it through a LangChain Tool. Check LangChain Integration for more details:

Example:

import os
from crewai import Agent, Task, Crew, Process
from langchain.tools import DuckDuckGoSearchRun
from langchain.agents import load_tools

search_tool = DuckDuckGoSearchRun()

# Loading Human Tools
human_tools = load_tools(["human"])

# Define your agents with roles and goals
researcher = Agent(
  role='Senior Research Analyst',
  goal='Uncover cutting-edge developments in AI and data science in',
  backstory="""You are a Senior Research Analyst at a leading tech think tank.
  Your expertise lies in identifying emerging trends and technologies in AI and
  data science. You have a knack for dissecting complex data and presenting
  actionable insights.""",
  verbose=True,
  allow_delegation=False,
  # Passing human tools to the agent
  tools=[search_tool]+human_tools
)
writer = Agent(
  role='Tech Content Strategist',
  goal='Craft compelling content on tech advancements',
  backstory="""You are a renowned Tech Content Strategist, known for your insightful
  and engaging articles on technology and innovation. With a deep understanding of

# Instantiate your crew with a sequential process
crew = Crew(
  agents=[researcher, writer],
  tasks=[task1, task2],
  verbose=2
)

# Get your crew to work!
result = crew.kickoff()
