render-imessage-cascade
Assemble an iMessage notification-cascade video ad (≈14s, 9:16) from a phone-on-desk plate + 3–5 messages — authentic Apple Messages banners composited in PIL (SF Pro text, green Messages icon, warm translucent-greige fill, soft shadow) spring in one-by-one at the BOTTOM and push the stack UP, a right-aligned Show-less/X pill rides above, the X clears the stack, then a serif end card resolves. FREE assembly (PIL + ffmpeg); the recipe supplies the per-brand plate, notifications, and end-card config and gates the paid plate-clean/music calls to their own capabilities. Use for the imessage-notifi

# render-imessage-cascade The free, deterministic renderer for the **imessage-notification-cascade** video ad format — the viral iOS trend where a phone sits on a desk and Apple Messages notifications STACK IN one after another. The signature mechanic is the **bottom-up push**: each new banner springs in at the bottom (nearest the phone) and shoves every existing one UP a row; the iOS grouped "⌄ Show less / ✕" pill rides above the stack; the ✕ clears the stack; then a serif end card resolves. This is a DETERMINISTIC composite — **no generative video of the UI**. Authentic iMessage banners are drawn in PIL and animated in FFmpeg over a Ken-Burns plate, so the notification text + wordmark stay pixel-crisp (a video model would smear type). The template recipe supplies the per-brand `plate`, `notifications`, and `end_card` config and gates the only paid steps — cleaning the plate (→ `create-image-fal`) and the music bed/pop (→ `create-music-elevenlabs`) — to their own capabilities. This capability itself makes **no paid calls**. ## Scripts (free) - `scripts/build_assets.py` — draws the assets from `config`: `nb-1..N.png` (authentic banners — green Messages icon, warm translucent-greige

How do I install it?
Run `npx skills add gooseworks-ai/goose-skills --skill render-imessage-cascade --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From gooseworks-ai/goose-skills, a repository with 1,091 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
