Tasklist Conventions

TaskList Conventions

Overview

TaskList is a built-in Claude Code feature for tracking task execution. Tasks are stored in ~/.claude/tasks/[session-uuid]/ and can be shared across sessions using the import-tasks skill.

When to Use TaskList

Use TaskList when:

• Executing a plan with multiple steps
• Tracking dependencies between work items
• Coordinating work across sessions or subagents
• Progress needs to be visible and trackable

Consider file-todos instead when:

• Findings need detailed documentation (Problem Statement, Findings, Solutions)
• Work items need to be committed to the repository
• Rich context with work logs is needed

Use both when:

• Review findings need documentation (file-todos) AND execution tracking (TaskList)

Built-in Tools

Task Fields

Required: subject (imperative form), description (detailed scope)

Recommended: activeForm (present continuous for spinner display)

Set via TaskUpdate: status (pending/in_progress/completed), addBlockedBy, addBlocks

Conventions

Task Subjects

Use imperative form (like git commits): "Implement user authentication", "Add validation for email field", "Write integration tests"

ActiveForm

Use present continuous: Subject "Run database migrations" → ActiveForm "Running database migrations"

Status Workflow

pending → in_progress → completed

Dependencies

TaskCreate: "Implement User model" → #1
TaskCreate: "Add authentication service" → #2
TaskUpdate: #2 addBlockedBy [#1]

Task Granularity

Create tasks that are completable in a focused session (1-4 hours), specific enough to know when done, independent or with clear dependencies, and verifiable.

Execution Loop

while TaskList shows pending tasks:
  TaskList                              # Check available work
  TaskUpdate: #X status=in_progress     # Claim next unblocked task
  # ... implementation ...
  TaskUpdate: #X status=completed       # Mark complete

Cross-Session Coordination

Including TaskList ID in Plan Files

---
title: Add user authentication
task_list_id: a69ce44f-1559-4052-89e2-66605323adca
---

Importing in Another Session

Use the import-tasks skill to import tasks from another session's TaskList.

Parallel Subagent Execution

Multiple agents can work on the same TaskList by importing it and claiming individual tasks.

Relationship to Other Systems

Recommended: File-todos for detailed findings, TaskList for execution tracking. Link them via description references.
