Reading Large Checklists

For large checklists with many tasks, use the right approach based on checklist size:

Strategy 1: Quick Preview (BEST for VERY large checklists) ⭐

checkvist_get_tasks_summary with preview: true

• Shows ONLY top-level tasks (no subtasks)

• Minimal data, perfect for huge checklists (1000+ tasks)

• Automatically uses compact mode

• Get quick overview, then drill down with get_task_tree

• Example:

  checkvist_get_tasks_summary(
    checklist_id: 941803,
    preview: true
  )

• Output:

  📋 Checklist Summary (5 top-level tasks, 847 total)
  ⚡ PREVIEW MODE: Showing only top-level tasks
  
  [ ] Main Project [12345]
  [ ] Archive [12350]
  [ ] Notes [12351]
  [ ] Resources [12352]
  [ ] Templates [12353]
  
  💡 TIP: Use checkvist_get_task_tree with a specific task ID to explore subtasks

Strategy 2: See Full Structure (for medium/large checklists)

checkvist_get_tasks_summary with compact: true

• Shows ENTIRE checklist in ultra-compact format

• Only displays: status, title, and ID (no metadata, no notes)

• Works for hundreds of tasks

• Example:

  checkvist_get_tasks_summary(
    checklist_id: 941803,
    compact: true,
    max_depth: 2
  )

Strategy 3: Explore Specific Branches

checkvist_get_task_tree (for detailed view of one branch)

• Get ONE specific task and ALL its subtasks with full details

• Shows metadata, notes, due dates, priorities, tags

• Perfect when you found interesting task in compact view

• Example: checkvist_get_task_tree(checklist_id: 941803, task_id: 71218558)

Strategy 4: Full Details for Smaller Checklists

checkvist_get_tasks_summary with compact: false (default)

• Shows everything with full metadata and notes

• Only use for checklists with <50 tasks

• May be too large for bigger checklists

checkvist_get_tasks

• Returns raw JSON structure

• May be stored in files that are harder to read

• Use only when you need to process JSON programmatically

Recommended Workflows

Option 1: Read Everything in Pages ⭐ (BEST for reading entire checklist)

1. checkvist_get_tasks_paginated(checklist_id: X, page: 1)
   → Shows first 3 top-level tasks with ALL their subtasks
2. checkvist_get_tasks_paginated(checklist_id: X, page: 2)
   → Shows next 3 top-level tasks with ALL their subtasks
3. Continue until you've read all pages

Claude can read ALL tasks this way without hitting size limits!

Option 2: Preview + Drill Down (faster for finding specific info)

1. checkvist_get_tasks_summary(checklist_id: X, preview: true)
   → See all top-level tasks (just 5-10 items)
2. Find interesting task in the preview
3. checkvist_get_task_tree(checklist_id: X, task_id: Y)
   → Get all details for that specific branch

Smart Syntax Support

Checkvist supports smart syntax in task content:

• ^tomorrow - Set due date

• #tag - Add tag

• !3 - Set priority (0-9)

• @username - Assign to user

Enable parsing with parse_tasks: true or parse: true parameters.
