You can get the GEMINI_API_KEY from Gemini AiStudio

In this file, we implement two agents: one for conducting research on a user-specified topic and another for generating blogs in the desired format. We define the goals and context for each agent, outlining the specific focus for the provided user topic. This functionality is achieved using the Agent class from CrewAI, with the initialization of the GEMINI_API_KEY.

Set up your tools.py file:
```
 from dotenv import load_dotenv
 load_dotenv()
 import os
 os.environ['SERPER_API_KEY'] = os.getenv('SERPER_API_KEY')
 from crewai_tools import SerperDevTool
 # Initialize the tool for internet searching capabilities
 tool = SerperDevTool()
```
You can get your SERPER API key from Link

In this file, we have initialized the Serper tool from CrewAI tools to utilize Google for data retrieval. Serper provides a cost-effective solution for accessing information from multiple sources.

Set up your Task.py file:

 from crewai import Task
 from tools import tool
 from agents import *

 # Research task
 research_task = Task(
   description=(
     "Research and identify key insights on {topic} to create a compelling blog post."
     "Focus on structuring the content with an engaging introduction, detailed pros and cons,"
     "and a practical project or code example if applicable."
     "Ensure the final output is informative, well-organized, and provides value to the reader."
   ),
   expected_output='A well-structured blog post with an introduction, pros and cons, and a project or code example, if relevant.',
   tools=[tool],  # Specify relevant research and writing tools
   agent=blog_researcher,  # Using the modified blog researcher agent
 )
 # Writing task with language model configuration
 write_task = Task(
   description=(
     "Create a detailed blog post on {topic}."
     "Include an engaging introduction, a balanced analysis of pros and cons,"
     "and a practical project or code example if applicable."
     "The blog should be clear, informative, and engaging, making the content accessible to readers of all levels."
   ),
   expected_output='A markdown-formatted blog post on {topic}, including an introduction, pros and cons, and a project or code example if relevant.',
   tools=[tool],  # Specify necessary writing, research, and code tools
   agent=blog_writer,  # Using the tailored blog writer agent
   async_execution=False,
   output_file='Crew_output.md'  # Specify the output file name
 )

In this file, we will define and initialize tasks for each agent using the Task class from CrewAI. We will provide a comprehensive description for each task, addressing all relevant details to ensure effective execution. We will specify the required tools and assign each tool to its respective agent. Additionally, we will designate a file name for storing the blog content.

Set up your main.py file:

 from crewai import Crew,Process
 from tasks import research_task,write_task
 from agents import blog_researcher,blog_writer
 ## Forming the tech focused crew with some enhanced configuration
 crew=Crew(
     agents=[blog_researcher,blog_writer],
     tasks=[research_task,write_task],
     process=Process.sequential,

 )
 ## starting the task execution process wiht enhanced feedback
 result=crew.kickoff(inputs={'topic':'Crew AI'})
 print(result)

In this file, we will configure the agents, tools, and tasks within the CrewAI framework. This includes initializing each agent with the appropriate tools and tasks and kicking off the topic for each agent, similar to how we use the invoke method in LangChain for queries.

Running our Application:
```
 # Go to terminal and switch to your directory
 python main.py
```
Upon successful execution of the project, a new file will be generated that stores all the content in the required format.
