Todo tool (`write_todos`)

The write_todos tool allows the Gemini agent to maintain an internal list of subtasks for multi-step requests.

Technical reference

The agent uses this tool to manage its execution plan and provide progress updates to the CLI interface.

Arguments

• todos (array of objects, required): The complete list of tasks. Each object includes:
  • description (string): Technical description of the task.
  • status (enum): pending, in_progress, completed, cancelled, or blocked.

Technical behavior

• Interface: Updates the progress indicator above the CLI input prompt.
• Exclusivity: Only one task can be marked in_progress at any time.
• Persistence: Todo state is scoped to the current session.
• Interaction: Users can toggle the full list view using Ctrl+T.

Use cases

• Breaking down a complex feature implementation into manageable steps.
• Coordinating multi-file refactoring tasks.
• Providing visibility into the agent’s current focus during long-running tasks.
