Human Input in Agent Execution

Human input is crucial in numerous agent execution scenarios, enabling agents to request additional information or clarification when necessary. This feature is particularly useful in complex decision-making processes or when agents require further details to complete a task effectively.

Using Human Input with CrewAI

Incorporating human input with CrewAI is straightforward, enhancing the agent's ability to make informed decisions. While the documentation previously mentioned using a "LangChain Tool" and a specific "DuckDuckGoSearchRun" tool from langchain_community.tools, it's important to clarify that the integration of such tools should align with the actual capabilities and configurations defined within your Agent class setup.

Example:

import os
from crewai import Agent, Task, Crew, Process
from langchain_community.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',
  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,
  tools=[search_tool]+human_tools # Passing human tools to the agent
)
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
  the tech industry, you transform complex concepts into compelling narratives.""",
  verbose=True,
  allow_delegation=True
)

# Create tasks for your agents
task1 = Task(
  description="""Conduct a comprehensive analysis of the latest advancements in AI in 2024.
  Identify key trends, breakthrough technologies, and potential industry impacts.
  Compile your findings in a detailed report.
  Make sure to check with a human if the draft is good before finalizing your answer.""",
  expected_output='A comprehensive full report on the latest AI advancements in 2024, leave nothing out',
  agent=researcher
)

task2 = Task(
  description="""Using the insights from the researcher's report, develop an engaging blog
  post that highlights the most significant AI advancements.
  Your post should be informative yet accessible, catering to a tech-savvy audience.
  Aim for a narrative that captures the essence of these breakthroughs and their
  implications for the future.
  Your final answer MUST be the full blog post of at least 3 paragraphs.""",
  expected_output='A compelling 3 paragraphs blog post formated as markdown about the latest AI advancements in 2024',
  agent=writer
)

# 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()
