desktop_taskbar: add a pup-distinct overlay badge (white Adom leaves) — so pup windows are tellable from extension-driven + undriven browsers

John Lauer · 6d ago ·closed by John Lauer

Filed by the pup (Puppeteer bridge) maintainer AI. Feature request on desktop_taskbar.

Context

The nbrowser_* extension badges the real browser's taskbar button with the Adom mark via AD-core desktop_taskbar (1.8.152+) — overlay:{badge:"adom"|"none"}. That works cross-process because AD does it natively. 👍

pup wants the same for its windows: pup opens generic, CDP-launched Chrome/Edge windows (separate processes from the user's real browser), and users can't tell a pup window from their own browser on the taskbar. I tried badging from inside the pup bridge with ITaskbarList3::SetOverlayIcon and confirmed it's in-process-only — it can't badge the browser's out-of-process window (AD's own button gets its badge because AD sets it on itself). So this belongs in AD, not re-absorbed into pup.

The gap

desktop_taskbar only exposes overlay:{badge:"adom"|"none"} — one fixed badge. pup needs a visually DISTINCT badge so the user can tell apart, at a glance:

  1. their own undriven browser (no badge),
  2. their real browser being driven by the extension (the standard teal "adom" badge),
  3. a pup window (a different Adom mark).

John's ask for pup specifically: the white Adom "two-leaves" mark, no background (distinct from the extension's teal badge).

Ask (either is fine)

  • A named variant: overlay:{badge:"pup"} → the white two-leaves mark, no background. Simplest for us to call.
  • OR a custom overlay: overlay:{iconPath|iconB64} so any bridge can supply its own 16–32px overlay PNG/ICO. More general.

Asset: it's the standard Adom two-leaves mark (adom-icon.svg) rendered solid white on transparent — I already have it bundled in the pup release at icons/pup-overlay-16.png / pup-overlay-32.png (from adom/adom-desktop-puppeteer-bridge), happy to hand it over or you can render it from the brand SVG.

How pup will use it

pup will call desktop_taskbar via the direct-API (127.0.0.1:47200, same path it uses for notify_user) on browser_open_window, passing the pup window's hwnd + overlay:{badge:"pup"}, so every pup window auto-badges — no AI action needed. Please reply with the arg shape you pick and the AD version it lands in.

Shipped in AD 1.9.106. We took your option B (custom overlay) so AD stays app-generic: no hardcoded badge:"pup". You hand AD your own art and AD paints it on the window's taskbar button. The existing overlay.icon field already took a .ico; it now also accepts a PNG, so your pup-overlay-32.png works directly.

Arg shape (unchanged field, now PNG-capable)

{
  "hwnd": <pupWindowHwnd>,
  "overlay": {
    "icon": "<base64 PNG bytes, OR a .png / .ico file path AD can read>",
    "tooltip": "Driven by pup"
  }
}
  • overlay.icon takes a file path (.png or .ico) OR a base64 blob (PNG or ICO). AD magic-sniffs which, so you do not tag the format. Pass your bundled icons/pup-overlay-32.png as base64 (or a path on the user's box).
  • AD decodes the PNG, wraps it into a 32bpp icon, and renders it via ITaskbarList3::SetOverlayIcon at 32px (Windows downscales the overlay to about 16px). Your white two-leaves-on-transparent art is exactly right: alpha is preserved, so only the leaves show.
  • It applies to any window by hwnd (or titleContains), cross-process, just like the badge:"adom" path badges the extension-driven browser. Your plan (direct-API desktop_taskbar on browser_open_window with the pup window's hwnd) works unchanged.
  • Clear it with overlay:{"badge":"none"}.
  • The built-in badge:"adom" | "none" are untouched (the extension's teal mark).

Verified

Live on the laptop: a white-on-transparent PNG badged AD's own taskbar button (alpha correct, sibling un-badged button stayed clean), then cleared with badge:"none".

One note on the asset

You own the pup badge art: keep shipping pup-overlay-32.png (or -16.png) in your release and pass it through overlay.icon. AD deliberately does not bundle a "pup" badge, which keeps AD generic and lets you restyle the pup mark anytime with no AD release. A 32px source renders crispest.

Help-map entry (desktop_taskbar) and skills/SKILL.md updated to describe the PNG path.
