## Customizable Attributes
|
|
Crafting an efficient CrewAI team hinges on the ability to tailor your AI agents dynamically to meet the unique requirements of any project. This section covers the foundational attributes you can customize.
|
|
|
|
### Key Attributes for Customization
|
|
- **Role**: Specifies the agent's job within the crew, such as 'Analyst' or 'Customer Service Rep'.
|
|
- **Goal**: Defines what the agent aims to achieve, in alignment with its role and the overarching objectives of the crew.
|
|
- **Backstory**: Provides depth to the agent's persona, enriching its motivations and engagements within the crew.
|
|
- **Tools**: Represents the capabilities or methods the agent uses to perform tasks, from simple functions to intricate integrations.
|
|
|
|
## Advanced Customization Options
|
|
Beyond the basic attributes, CrewAI allows for deeper customization to enhance an agent's behavior and capabilities significantly.
|
|
|
|
### Language Model Customization
|
|
Agents can be customized with specific language models (`llm`) and function-calling language models (`function_calling_llm`), offering advanced control over their processing and decision-making abilities.
|
|
|
|
### Enabling Memory for Agents
|
|
CrewAI supports memory for agents, enabling them to remember past interactions. This feature is critical for tasks requiring awareness of previous contexts or decisions.
|
|
|
|
## Performance and Debugging Settings
|
|
Adjusting an agent's performance and monitoring its operations are crucial for efficient task execution.
|
|
|
|
### Verbose Mode and RPM Limit
|
|
- **Verbose Mode**: Enables detailed logging of an agent's actions, useful for debugging and optimization.
|
|
- **RPM Limit**: Sets the maximum number of requests per minute (`max_rpm`), controlling the agent's query frequency to external services.
|
|
|
|
### Maximum Iterations for Task Execution
|
|
The `max_iter` attribute allows users to define the maximum number of iterations an agent can perform for a single task, preventing infinite loops or excessively long executions.
|
|
|
|
## Customizing Agents and Tools
|
|
Agents are customized by defining their attributes and tools during initialization. Tools are critical for an agent's functionality, enabling them to perform specialized tasks. In this example we will use the crewAI tools package to create a tool for a research analyst agent.
|
|
|
|
```shell
|
|
pip install 'crewai[tools]'
|
|
```
|
|
|
|
### Example: Assigning Tools to an Agent
|
|
```python
|
|
import os
|
|
from crewai import Agent
|
|
from crewai_tools import SeperDevTool
|
|
|
|
# Set API keys for tool initialization
|
|
os.environ["OPENAI_API_KEY"] = "Your Key"
|
|
os.environ["SERPER_API_KEY"] = "Your Key"
|
|
|
|
# Initialize a search tool
|
|
search_tool = SeperDevTool()
|
|
|
|
# Initialize the agent with advanced options
|
|
agent = Agent(
|
|
role='Research Analyst',
|
|
goal='Provide up-to-date market analysis',
|
|
backstory='An expert analyst with a keen eye for market trends.',
|
|
tools=[serper_tool],
|
|
memory=True,
|
|
verbose=True,
|
|
max_rpm=10, # Optinal: Limit requests to 10 per minute, preventing API abuse
|
|
max_iter=5, # Optional: Limit task iterations to 5 before the agent tried to gives its best answer
|
|
allow_delegation=False
|
|
)
|
|
```
|
|
|
|
## Delegation and Autonomy
|
|
Controlling an agent's ability to delegate tasks or ask questions is vital for tailoring its autonomy and collaborative dynamics within the CrewAI framework.
|
|
|
|
### Example: Disabling Delegation for an Agent
|
|
```python
|
|
agent = Agent(
|
|
role='Content Writer',
|
|
goal='Write engaging content on market trends',
|
|
backstory='A seasoned writer with expertise in market analysis.',
|
|
allow_delegation=False
|
|
)
|
|
```
|
|
|
|
## Conclusion
|
|
Customizing agents in CrewAI by setting their roles, goals, backstories, and tools, alongside advanced options like language model customization, memory, and performance settings, equips a nuanced and capable AI team ready for complex challenges. |
