Habit Track

Build and manage a habit tracking kanban board:

1. Setup — Define habit data shape in the canvas:
   • Fields: name, description, status (Not Started/In Progress/Done), streak, lastCompleted
2. Build canvas — Habit tracker board (write_file canvas TSX):
   • KPIs: total habits, active today, best streak
   • Kanban: 3-column grid (Not Started / In Progress / Done)
   • Each habit is a card with: name, streak badge, action button
   • Buttons: “Start” (→ In Progress), “Done” (→ Done), “Reset” (→ Not Started) — handled as local React state in the canvas component
3. Add habit — When user says “add habit [name]”:
   • Add a new row to the canvas with status “Not Started” and streak 0, then re-write the file
4. Complete — When user says “done [habit]”:
   • Update status to Done, increment streak, set lastCompleted to today via write_file
5. Streaks — Track streaks in memory:
   • Increment when completed on consecutive days
   • Reset to 0 if a day is missed
   • Celebrate milestones (7, 30, 100 days)
6. Reset daily — On morning heartbeat, move all “Done” items back to “Not Started” for the new day
