v2.20.0 - Subtasks

July 2026

Subtasks (#78) - break a task into a checklist of one-line items, each with a done state, a manual order, and an optional deadline.
- Subtasks show inline, clubbed under their parent on every surface - the desktop table (a full-width sub-row beneath the task), the mobile card, and the board card - as tickable circles with a "2/5" progress badge. Tap a circle to tick a step without opening anything. A subtask with a deadline shows that date inline next to it.
- The task detail (modal + /tasks/:id page) has a full subtask editor: add inline, tick, set/clear a per-subtask deadline, delete, and drag-reorder.
- Completing a parent that still has open subtasks asks what to do: complete them all, or move them out as their own standalone tasks (kept in the parent's project, with a back-reference). Recurring tasks get the same prompt, then the next occurrence spawns with a fresh, all-unchecked copy of the checklist.
MCP: 7 new tools bringing total to 36: 6 subtask tools (add_subtask, list_subtasks, set_subtask_completion, update_subtask, delete_subtask, reorder_subtasks) plus find - one by-name search over both tasks and subtasks that tags each hit task or subtask (subtasks carry their parent), so "I finished wire up the waitlist form" resolves in a single call without knowing which task it's under.

New Subtasks table (Tasks 1-to-many, cascade delete) mirroring the TaskComment/CheckIn pattern. Tasks gain response-only subtaskCount / completedSubtaskCount (always present) and a subtasks[] array (loaded on the detail, and on the list only when the web passes ?includeSubtasks=true for the inline checklist; MCP's list_tasks stays lean with counts only).
New frontend components: SubtaskChecklist (the inline clubbed list, shared by card + table + board), SubtaskSection (full editor with @dnd-kit drag-reorder), CompleteWithSubtasksDialog (the complete-all vs pull-out prompt). First drag-and-drop dependency: @dnd-kit.
