The Agent

An agent is an autonomous unit programmed to:

• Perform tasks

• Make decisions

• Communicate with other agents

Think of an agent as a member of a team, with specific skills and a particular job to do. Agents can have different roles like 'Researcher', 'Writer', or 'Customer Support', each contributing to the overall goal of the crew.

Agent Attributes

Attribute	Description
Role	Defines the agent's function within the crew. It determines the kind of tasks the agent is best suited for.
Goal	The individual objective that the agent aims to achieve. It guides the agent's decision-making process.
Backstory	Provides context to the agent's role and goal, enriching the interaction and collaboration dynamics.
Model	Represents the language model that will run the agent. It dynamically fetches the model name from the OPENAI_MODEL_NAME environment variable, defaulting to "gpt-4" if not specified.
Tools	Set of capabilities or functions that the agent can use to perform tasks. Expected to be instances of custom classes compatible with the agent's execution environment. Tools are initialized with a default value of an empty list.
Verbose	Setting this to True configures the internal logger to provide detailed execution logs, aiding in debugging and monitoring. Default is False.
Allow Delegation	Agents can delegate tasks or questions to one another, ensuring that each task is handled by the most suitable agent. Default is True.
Cache	Indicates if the agent should use a cache for tool usage. Default is True.
Image	Used to visually identify your Agent in your Agent library.
Knowledge Base	A Knowledge Base with private knowledge that your Agent can use to solve Tasks.
Assistant	A personal Assistant that can be used to help the Agent solve its Tasks.
Crew	The Crew that the Agent is part of.
Task	The Task that is assigned to the Agent.

Task

In the crewAI framework, tasks are specific assignments completed by agents. They provide all necessary details for execution, such as a description, the agent responsible, required tools, and more, facilitating a wide range of action complexities.

Tasks within crewAI can be collaborative, requiring multiple agents to work together. This is managed through the task properties and orchestrated by the Crew's process, enhancing teamwork and efficiency.

Attribute	Description
Description	A clear, concise statement of what the task entails.
Agent	The agent responsible for the task, assigned either directly or by the crew's process.
Expected Output	A detailed description of what the task's completion looks like.
Name	A short name for your Task to find it for further usage.
Crew	The Crew that is responsible for solving the Task.

Crew

A crew in crewAI represents a collaborative group of agents working together to achieve a set of tasks. Each crew defines the strategy for task execution, agent collaboration, and the overall workflow.

Attribute	Description
Description	A clear, concise statement of what the task entails.
Name	A short name for your Crew to find it for further usage
Process	The process flow (e.g., sequential, hierarchical) the crew follows.
Verbose	The verbosity level for logging during execution.
Language	Language used for the crew, defaults to English.
Memory	Utilized for storing execution memories (short-term, long-term, entity memory).
Cache	Specifies whether to use a cache for storing the results of tools' execution.
Full Output	Whether the crew should return the full output with all tasks outputs or just the final output.
Output Log File	Whether you want to have a file with the complete crew output and execution. You can set it using True and it will default to the folder you are currently in and it will be called logs.txt or passing a string with the full path and name of the file.
Image	An image for the Crew to visually identify it for further customization.
Agents	The list of Agents that are part of this Crew.
Tasks	The list of Tasks that are part of this Crew.
