Human Input on Execution	Comprehensive guide on integrating CrewAI with human input during execution in complex decision-making processes or when needed help during complex tasks.

Human Input in Agent Execution

Human input plays a pivotal role in several agent execution scenarios, enabling agents to seek additional information or clarification when necessary. This capability is invaluable in complex decision-making processes or when agents need more 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:

pip install crewai
pip install 'crewai[tools]'

import os
from crewai import Agent, Task, Crew
from crewai_tools import SerperDevTool

from langchain.agents import load_tools

os.environ["SERPER_API_KEY"] = "Your Key" # serper.dev API key
os.environ["OPENAI_API_KEY"] = "Your Key"


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

# Define your agents with roles, goals, and tools
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."
  ),
  expected_output='A compelling 3 paragraphs blog post formatted 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()
