Supernote Mystyle

Supernote MyStyle round-trip

This skill is a process for passing a checklist back and forth between a person and an agent through a Supernote tablet. The moving parts:

spec.json  ──render──▶  template.png  ──drop in MyStyle──▶  write on tablet
   ▲                                                              │
   │                                                          export
 reconcile ◀──read ticked boxes──  EXPORT/*.png  ◀────────────────┘

The spec is the contract. It is small, human-editable JSON, so either side can author or amend it: the agent generates one from a conversation, or the person hands one over to regenerate a template. Everything else (device sizing, house style, the export read) hangs off that spec.

Supernote tablets show any PNG in their cloud MyStyle folder as a writable template (Create Note → template → My Style), and export handwritten notes to a EXPORT folder that Google Drive OCRs — which is what makes the round-trip work.

Design a template as a reusable form (a weekly reset, a review checklist, a packing list), not a one-off — it repeats on every page created from it.

When to reach for this

• The user wants a checklist/log/form they pen-check on a Supernote.
• They mention MyStyle, Nomad, Manta, A5X/A6X, or "e-ink template."
• They want a tablet note to feed back into a list that's tracked somewhere.

Steps

1. Pick the device. The template MUST match the screen's native pixel resolution or it renders soft. Presets and specs are in references/devices.md (Nomad/A6X2 = 1404×1872, Manta/A5X2 = 1920×2560, A5X/A6X = 1404×1872).

2. Author or accept a spec. JSON with title, one-line subtitle, an all-caps footer tag (a version stamp like RESET_V1), optional footer_left, and one or two columns of {"section": ...} and {"item": ..., "pri": true} rows (pri → ★ don't-skip marker). One page; two columns fit ~60 items on a Nomad. Start from examples/checklist.spec.json.

3. Render — always --mono (1-bit; e-ink-crisp and ~25KB):

   python3 scripts/make_template.py examples/checklist.spec.json --device nomad --mono -o RESET_V1.png
   

   Read the PNG back and check nothing collides with the footer; trim or split if a column overruns.

4. Deliver to MyStyle. Hand the PNG to the user to drop into Supernote/MyStyle on their Drive/Dropbox (reliable). Only place it directly if a cloud connector with write access is present AND the small file uploads cleanly — otherwise a corrupt upload is worse than a drag-and-drop, so deliver the file.

5. (Optional) Close the loop when they've written on it — see below.

The round-trip loop (export → master list)

The person ticks boxes on the tablet and exports the note; it lands in the cloud EXPORT folder. Three parts — the middle one is a vision read, not code:

1. Find the newest matching export:

   python3 scripts/sync_export.py latest ./EXPORT --contains RESET --newer-than-hours 36
   

2. Read it — open the PNG/PDF and see which boxes are ticked (check, X, or filled box). Handwriting detection is the agent's judgement; don't fake it in code.
3. Apply the ticked labels to the master Markdown list (source of truth, one - [ ] item per line):

   python3 scripts/sync_export.py apply master.md --checked "Item A" "Item B"
   

   It flips [ ] → [x] on loose label matches and appends a dated reconciliation line.

To run it unattended, schedule a task that does 1–3 on a cadence and reports what's still open. That needs the cloud connector and master list reachable in the scheduled session; if they aren't, have it say so rather than guess.

The spec contract, in full

{
  "title":       "WEEKLY RESET",
  "subtitle":    "Nomad · tick as you go ·  * = must-do",
  "tag":         "RESET_V1",
  "footer_left": "SUPERNOTE NOMAD · MYSTYLE",
  "columns": [
    [ {"section":"MORNING"}, {"item":"Inbox to zero","pri":true}, {"item":"Plan the day"} ],
    [ {"section":"WEEKLY"},  {"item":"Review goals","pri":true},  {"item":"Back up files"} ]
  ]
}

• 1 column = full width; 2 columns = split page. Keep to one page.
• pri adds the ★ marker and pairs with a * = … note in the subtitle.
• The tag is the version signature — bump it (RESET_V2) when you change the form, so old exports stay distinguishable.

Design system

Monospace bold, hairline rules, checkbox squares, ★ priority polygons, all-caps version tag in the footer — deliberately spare so handwriting dominates. Palette and the important 1-bit threshold rule (light greys vanish under --mono; keep elements darker than the cutoff) are in references/house-style.md. Reskin by editing the palette constants or fonts in make_template.py.

Sync with an are-we-there-yet trip (shared source of truth)

If the list also lives in an are-we-there-yet trip PWA, don't maintain it twice. That app reads a bring array (and lists) from <trip>/event.json. Generate the Supernote template FROM that same file, so the tablet and the PWA always show the same items:

python3 scripts/from_event.py <trip>/event.json --list bring --device nomad --mono -o BRING_V1.png

from_event.py shortens the PWA's long descriptive lines into tight e-ink labels and marks must-do items ★ by keyword. event.json stays the single master — edit it, regenerate, both views match.

What syncs, and what doesn't:

• Items (the list): fully shared — one event.json feeds both. ✅
• Checked state, Supernote → tracker: the export loop above reads ticks off the tablet and can write them into a master *.md or a committed <trip>/checklist-state.json. ✅
• Checked state, PWA ↔ Supernote (live, two-way): NOT possible as-is. The PWA is static (GitHub Pages) and stores checks in per-device localStorage, which nothing outside that browser can read or write. True two-way check sync needs a shared backend, or a rework where the app hydrates its initial check state from a committed checklist-state.json that the export loop writes. Ink on paper can't be pushed back automatically either. Be upfront about this limit rather than implying live sync.

Notes

• One page per template; prefer two columns over two pages.
• The EXPORT folder holds unrelated notes — always filter by tag/--contains and only touch the target list.
• examples/ ships two specs: a generic checklist.spec.json and a real packing.spec.json to show a fuller, two-column layout.
• scripts/from_event.py bridges to an are-we-there-yet event.json (above).
