Subtasks allow you to break down complex tasks into smaller, more manageable pieces. Each subtask is linked to a specific task attempt and inherits the same project and branch context.

​
Creating Subtasks

Current attempt toolbar showing the Create Subtask button with GitFork icon
To create a subtask from an existing task attempt:
1

Navigate to the task attempt

Open the task you want to create subtasks for.
2

Click Create Subtask

Click the triple dot icon in the top right of the task, then select Create Subtask.
3

Fill in subtask details

The task creation dialog opens with the parent task attempt and base branch automatically set. Add your subtask title and description.
4

Save the subtask

Click Save to create the subtask. It will appear as a new task on your kanban board.
When you create a subtask, it automatically inherits the base branch from its parent task attempt, ensuring consistency in your development workflow.

​
Viewing Tasks with Subtasks

Task view showing a parent task with its associated subtasks listed in the Task Relationships panel
When viewing a parent task, you can see its subtasks in the Task Relationships panel. This collapsible section shows:
  • Child Tasks with a count (e.g., “CHILD TASKS (1)”)
  • Individual subtask titles with links to view them
  • Easy navigation between parent and child tasks
This helps you track progress across all related work items and understand the task hierarchy at a glance.

​
Viewing Subtask Details

Subtask detail view showing parent task information in the Task Relationships panel
When viewing a subtask, the Task Relationships panel displays:
  • Parent Task section showing the parent task title
  • Direct link to navigate to the parent task
  • Clear visual indication that this is a child task
  • Context about the parent-child relationship
The subtask also shows its own Create Subtask button, allowing you to create nested subtasks if needed.

​
How Subtasks Work

Subtasks in Vibe Kanban follow these key principles:

​
Git Branching Workflow

Subtasks create their own feature branches that can work independently while maintaining connection to the parent task:

​
Parent-Child Relationships

  • Subtasks are linked to specific task attempts, not just tasks
  • Each subtask knows which attempt created it
  • Multiple subtasks can be created from the same parent attempt

​
Branch Inheritance

  • Subtasks automatically inherit the base branch from their parent attempt
  • This ensures subtasks work within the same development context
  • You can modify the branch when creating the subtask if needed

​
Independent Task Lifecycle

  • Subtasks appear as regular tasks on your kanban board
  • Each subtask has its own lifecycle (To do → In Progress → In Review → Done)
  • Subtasks can have their own task attempts and coding agents
