🎯 Planning and Reasoning

DroidRun’s planning system allows the DroidAgent to break down complex goals into manageable tasks.

​
📚 Overview

When the reasoning=True parameter is enabled, DroidAgent uses a PlannerAgent to:
  1. Analyze the user goal
  2. Break it down into sequential tasks
  3. Track task execution
  4. Adapt plans based on results

​
🔄 How Planning Works

1

Task Analysis

The PlannerAgent receives the user’s goal and analyzes what needs to be done
2

Task Generation

PlannerAgent creates a task list using the TaskManager
3

Sequential Execution

Tasks are executed one by one using the CodeActAgent
4

Progress Tracking

Successfully completed tasks are marked and failed tasks are noted
5

Plan Adjustment

After tasks are executed, the plan is revisited and updated as needed

​
🛠️ Task Management

The TaskManager component handles: 
# Internal task representation
{
    "description": "Open the Settings app",
    "status": "pending"  # pending, attempting, completed, failed
}

# After execution, additional details are added
{
    "description": "Open the Settings app",
    "status": "completed",
    "execution_details": "App launched successfully",
    "step_executed": 1,
    "codeact_steps": 3
}

​
📋 Task History

The DroidAgent maintains a complete task history: 
# Get execution history in results
result = await agent.run()
task_history = result["task_history"]

# Example task history structure
[
    {"description": "Open Settings app", "status": "completed", ...},
    {"description": "Navigate to Display", "status": "completed", ...},
    {"description": "Enable dark mode", "status": "completed", ...}
]

​
⚙️ Using Planning

Enable planning during agent creation: 
agent = DroidAgent(
    goal="Configure device settings",
    llm=llm,
    tools_instance=tools,
    reasoning=True,  # Enable planning
    max_steps=15,    # Maximum planning iterations
    timeout=1000     # Overall timeout in seconds
)

​
🔄 Memory and Context

The planning system maintains context between iterations:
  1. Task History: Keeps track of completed and failed tasks
  2. Memory Storage: Remembers important information via tools.remember()
  3. Execution Details: Stores tool execution results
# Store important information for future planning
await tools.remember("Device is running Android 11")
await tools.remember("Wi-Fi password is 'example123'")

​
🧠 When to Use Planning

Planning is most effective for:

Complex Goals

Multi-step operations requiring coordination

Error-Prone Tasks

Operations that may require retries or error handling

Dynamic Workflows

Tasks where next steps depend on previous results

UI Workflows

Navigation through multiple app screens

💡 Best Practices

  1. Clear Goal Description
    • Be specific about what you want to achieve
    • Include success criteria when possible
  2. Appropriate Step Limits
    • Increase max_steps for complex workflows
    • Consider device and network performance
  3. Error Handling
    • Check task_history for debugging failed tasks
  4. Memory Usage
    • Use tools.remember() for key information
    • Include discovered data in task descriptions
