name	sketch-lab
description	Generate Sketch Lab architecture diagrams and open them via a share URL. Use when the user asks for a Sketch Lab diagram, sketchlab.app board, 3D floor stack diagram, architecture sketch to open in Sketch Lab, or to emit GeneratedGraph JSON for Sketch Lab. Not for Mermaid, Excalidraw, or Mission Control diagram modals.

Sketch Lab diagrams

Produce a GeneratedGraph JSON object, then open it in Sketch Lab with a ?g= URL. Do not emit Mermaid, ASCII art, or markdown fences around the JSON when building the URL.

App origin (production): https://sketchlab.webdevcody.com

Override if the user gives another base (e.g. http://localhost:5173).

Workflow

1. Draft a GeneratedGraph that matches the schema below.
2. Prefer 4–14 nodes unless the user asks for more (hard cap 48 nodes / 96 edges / 48 floors).
3. Build and open:

{ORIGIN}/?g={URI_ENCODED_JSON}

Example (shell — works without lz-string):

ORIGIN="${SKETCHLAB_ORIGIN:-https://sketchlab.webdevcody.com}"
JSON='{"name":"Demo","layers":[],"nodes":[{"id":"api","label":"API","kind":"icon","icon":"microservice","color":"#0f2740","layer":0}],"edges":[]}'
open "${ORIGIN}/?g=$(python3 -c 'import urllib.parse,sys; print(urllib.parse.quote(sys.argv[1], safe=""))' "$JSON")"

On Linux use xdg-open instead of open. Tell the user the URL if you cannot open a browser.
