Usage

DeepAgent uses the write_todos tool to create and manage structured task lists. The agent automatically uses this tool when tasks require 3+ steps or are non-trivial.

​
Tool Signature

write_todos(todos: List[Dict[str, Any]]) -> str
Todo Fields:
  • content: Description of the task
  • status: One of "pending", "in_progress", "completed", "cancelled"
  • id: Unique identifier (string)

​
Example

import asyncio
from upsonic.agent.deepagent import DeepAgent
from upsonic import Task

async def main():
    agent = DeepAgent(model="anthropic/claude-sonnet-4-5")
    
    task = Task(description="""
Create a complete web application with:
- User authentication system
- Product catalog with search
- Shopping cart functionality
- Payment processing

Plan the implementation, then execute all tasks.
Save each component to separate files in /app/ directory.
""")

    result = await agent.do_async(task)
    print(result)
    
    # Check the plan created
    plan = agent.get_current_plan()
    print(f"\nExecution Plan ({len(plan)} tasks):")
    for todo in plan:
        print(f"  [{todo['status']}] {todo['content']}")

asyncio.run(main())

​
Key Points

  • Minimum 2 todos required for initial plan
  • Agent must update todos after each task completion
  • Todos are stored per task instance
  • Use get_current_plan() to access todos programmatically
