用法

单工具用法

下面展示如何从 Tool Pack 中使用某个特定工具：

from crewai import Agent, Task, Crew
from crewai_tools import MergeAgentHandlerTool

# Create a tool for Linear issue creation
linear_create_tool = MergeAgentHandlerTool.from_tool_name(
    tool_name="linear__create_issue",
    tool_pack_id="134e0111-0f67-44f6-98f0-597000290bb3",
    registered_user_id="91b2b905-e866-40c8-8be2-efe53827a0aa"
)

# Create a CrewAI agent that uses the tool
project_manager = Agent(
    role='Project Manager',
    goal='Manage project tasks and issues efficiently',
    backstory='I am an expert at tracking project work and creating actionable tasks.',
    tools=[linear_create_tool],
    verbose=True
)

# Create a task for the agent
create_issue_task = Task(
    description="Create a new high-priority issue in Linear titled 'Implement user authentication' with a detailed description of the requirements.",
    agent=project_manager,
    expected_output="Confirmation that the issue was created with its ID"
)

# Create a crew with the agent
crew = Crew(
    agents=[project_manager],
    tasks=[create_issue_task],
    verbose=True
)

# Run the crew
result = crew.kickoff()
print(result)

从 Tool Pack 加载多个工具

你可以一次性加载 Tool Pack 中所有可用工具：

from crewai import Agent, Task, Crew
from crewai_tools import MergeAgentHandlerTool

# Load all tools from the Tool Pack
tools = MergeAgentHandlerTool.from_tool_pack(
    tool_pack_id="134e0111-0f67-44f6-98f0-597000290bb3",
    registered_user_id="91b2b905-e866-40c8-8be2-efe53827a0aa"
)

# Create an agent with access to all tools
automation_expert = Agent(
    role='Automation Expert',
    goal='Automate workflows across multiple platforms',
    backstory='I can work with any tool in the toolbox to get things done.',
    tools=tools,
    verbose=True
)

automation_task = Task(
    description="Check for any high-priority issues in Linear and post a summary to Slack.",
    agent=automation_expert
)

crew = Crew(
    agents=[automation_expert],
    tasks=[automation_task],
    verbose=True
)

result = crew.kickoff()

sprint_planner = Agent(
    role='Sprint Planner',
    goal='Plan and organize sprint tasks',
    backstory='I help teams plan effective sprints with well-defined tasks.',
    tools=[create_tool, update_tool],
    verbose=True
)

planning_task = Task(
    description="Create 5 sprint tasks for the authentication feature and set their priorities based on dependencies.",
    agent=sprint_planner
