Google Tasks Skill

Overview

This skill provides comprehensive Google Tasks API integration, enabling Claude Code to manage task lists and tasks programmatically. It shares OAuth authentication with other Google skills (Calendar, Drive, Sheets, Docs, Contacts, Gmail) for seamless multi-service workflows.

Authentication

Shared OAuth Token: This skill uses the same OAuth credentials as other Google skills:

• Credentials: ~/.claude/.google/client_secret.json
• Token: ~/.claude/.google/token.json
• Scope: https://www.googleapis.com/auth/tasks

The token file contains all Google API scopes, so if you've authenticated with Calendar, Drive, or other Google skills, Tasks will work automatically.

First-Time Setup

If the Tasks scope isn't yet authorized:

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasklists

This will trigger the OAuth flow if needed.

Task List Operations

List All Task Lists

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasklists

Returns all task lists in the user's account.

Get a Specific Task List

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb get_tasklist --id "TASKLIST_ID"

Create a New Task List

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_tasklist --title "Project Tasks"

Update a Task List

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb update_tasklist --id "TASKLIST_ID" --title "Updated Title"

Delete a Task List

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb delete_tasklist --id "TASKLIST_ID"

Task Operations

List Tasks in a Task List

# List all tasks (including completed)
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasks --tasklist "TASKLIST_ID" --show_completed true

# List only incomplete tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasks --tasklist "TASKLIST_ID"

# List with hidden tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasks --tasklist "TASKLIST_ID" --show_hidden true

Get a Specific Task

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb get_task --tasklist "TASKLIST_ID" --id "TASK_ID"

Create a Task

  --due "2025-12-20"

Complete a Task

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb complete_task --tasklist "TASKLIST_ID" --id "TASK_ID"

Uncomplete a Task

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb uncomplete_task --tasklist "TASKLIST_ID" --id "TASK_ID"

Move a Task

# Move to top of list
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb move_task --tasklist "TASKLIST_ID" --id "TASK_ID"

# Move after a specific task
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb move_task \
  --tasklist "TASKLIST_ID" \
  --id "TASK_ID" \
  --previous "PREVIOUS_TASK_ID"

# Move as subtask of another task
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb move_task \
  --tasklist "TASKLIST_ID" \
  --id "TASK_ID" \
  --parent "PARENT_TASK_ID"

Delete a Task

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb delete_task --tasklist "TASKLIST_ID" --id "TASK_ID"

Clear Completed Tasks

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb clear_completed --tasklist "TASKLIST_ID"

Natural Language Examples

User: "Show me all my task lists"

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasklists

User: "Create a new task list called 'Home Renovation'"

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_tasklist --title "Home Renovation"

User: "Add a task to buy paint for the living room, due next Friday"

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_task \
  --tasklist "TASKLIST_ID" \
  --title "Buy paint for living room" \
  --due "2025-12-05"

User: "Mark the grocery shopping task as done"

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb complete_task --tasklist "TASKLIST_ID" --id "TASK_ID"

User: "Show me all incomplete tasks in my work list"

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasks --tasklist "WORK_LIST_ID"

User: "Delete all completed tasks from my personal list"

ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb clear_completed --tasklist "PERSONAL_LIST_ID"

Workflow Patterns

Project Task Management

# 1. Create a project task list
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_tasklist --title "Website Redesign"

# 2. Add main tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_task --tasklist "LIST_ID" --title "Design mockups"
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_task --tasklist "LIST_ID" --title "Frontend development"
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_task --tasklist "LIST_ID" --title "Backend API"

# 3. Add subtasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_task \
  --tasklist "LIST_ID" \
  --title "Create wireframes" \
  --parent "DESIGN_TASK_ID"

Daily Task Review

# List all incomplete tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb list_tasks --tasklist "LIST_ID"

# Complete finished tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb complete_task --tasklist "LIST_ID" --id "TASK_ID"

# Clear old completed tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb clear_completed --tasklist "LIST_ID"

Calendar + Tasks Integration

When a calendar event requires follow-up tasks:

# After creating/reviewing a calendar event, create related tasks
ruby ~/.claude/skills/tasks/scripts/tasks_manager.rb create_task \
  --tasklist "WORK_LIST_ID" \
  --title "Prepare meeting agenda" \
  --notes "For project kickoff on Monday" \
  --due "2025-12-06"

Output Format

All commands return JSON with this structure:

Success:

{
  "status": "success",
  "code": 0,
  "data": { ... },
  "message": "Operation completed successfully"
}

Error:

{
  "status": "error",
  "code": 1,
  "message": "Error description"
}

Exit Codes

• 0: Success
• 1: General failure
• 2: Authentication error
• 3: API error
• 4: Invalid arguments

Task Object Structure

Tasks returned from the API include:

• id: Unique task identifier
• title: Task title
• notes: Task description/notes
• status: "needsAction" or "completed"
• due: Due date (RFC 3339 format)
• completed: Completion timestamp
• parent: Parent task ID (for subtasks)
• position: Order within the list
• links: Associated URLs
• hidden: Whether task is hidden
• deleted: Whether task is deleted

Integration with Other Google Skills

This skill works seamlessly with:

• Calendar: Create tasks from events, link tasks to meetings
• Drive: Reference documents in task notes
• Sheets: Export task data for reporting
• Docs: Link project documents to tasks
• Contacts: Assign tasks related to contacts
• Gmail: Create tasks from email threads

All skills share the same OAuth token, so authentication is unified.

Error Handling

Common errors and solutions:

"Authentication required": Run any command to trigger OAuth flow "Task list not found": Verify the task list ID with list_tasklists "Task not found": Verify the task ID with list_tasks "Invalid due date": Use YYYY-MM-DD format

Best Practices

1. Use task lists for organization: Group related tasks in dedicated lists
2. Leverage subtasks: Break complex tasks into manageable subtasks
3. Set due dates: Help prioritize with explicit deadlines
4. Add notes: Include context and details in task notes
5. Regular cleanup: Use clear_completed to remove finished tasks
