Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00180 | $0.02706 |
| Opus 5.5 | $0.00072 | $0.01082 |
| Sonnet 5.5 | $0.00036 | $0.00541 |
| Haiku 4.5 | $0.00018 | $0.00271 |
Grade A, and why
shared-product-motion-video scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Product motion video (house style)
Produce short product films that look like a person annotating the real product on a warm notebook page: off-white paper with a faint dot grid, heavy black headlines that pop in word by word, pastel highlighter tags, pen marks that draw themselves around the thing that matters, the product's real UI inside device frames and desktop windows, a cursor that visibly clicks, and a quiet synthesised soundtrack whose clicks and chimes land on the frame.
Two formats:
- Promo: at most 40 s, sells one idea through a hook, a brand lockup, one proof per scene, an outcome and an end card.
- Tutorial: 50 to 120 s, teaches one task in numbered steps on real footage, no voice.
The style was extracted from three shipped Desquared films (a 40 s promo and two tutorials of 51 s and 57 s). Every number in this skill comes from their source code, not from taste.
Non-negotiables
- Real product UI only. Render it from code or capture it clean (
references/capture.md). Never a mock-up, a redraw or lorem ipsum. Every number on screen is computed from the product. - Everything is a function of time. Each frame is computed from
tthrough a window and a named easing curve, so any still can be rendered on its own. Check stills before rendering the film. - One timing source for picture and sound. A sound is declared next to the picture it belongs to, in the same scene-local time, never typed a second time.
- The film works muted. Captions carry the story; there is no voiceover by default.
- Nothing paid by default. Music and effects are synthesised; fonts are open licence. Ask before adding any paid text-to-speech, stock music or render service.
The style in one screen
Full values and rationale: references/house-style.md (look), references/motion.md (motion,
pacing, cursor), references/sound.md (sound).
| Area | Rule |
|---|---|
| Canvas | 1920 x 1080, 30 fps. Laid out on a 960 x 540 dp page at density 2 (1 dp = 2 px) |
| Paper | #FBFAF7; dots #E3E1DB, radius 0.9 dp, every 24 dp, drifting 3 dp/s |
| Ink | text #191919, body #6F6E69, faint #A5A39E, hairline #E6E4DF, cards white |
| Highlighters | yellow #FBE7A1, blue #D6E8F5, green #DDEEDC, pink #F7DDE6, purple #E9E1F5, orange #FBE3CF: one per section tag, rotating by scene |
| UI inks | #2F6FDE selection, focus, ripples; #2E8B57 ticks and success |
| Brand colour | only the app icon and at most one accent |
| Type | Display (Inter Display, or SF Pro Display) Black/Bold, tracking -0.02em, line 1.06; Text (Inter) line 1.4; one word per scene in italic serif (Newsreader); mono (JetBrains Mono) for tags, paths and code |
| Sizes (sp) | hook 66 to 74 Black; wordmark 70; tutorial title 62; caption title 36 to 40 Bold; detail 15; note 16 italic; tags 11 mono; nothing to read under 11 |
| Grid | margin 60 dp; caption column x 60, y 150, 300 wide; product area x 372, 560 wide; step dots at y 24 right-aligned to 936 |
| Entrances | rise 18 dp + fade over 0.4 to 0.6 s, easeOutCubic; words 0.5 s each, 0.09 s apart, easeOutBack 1.4 |
| Landings | cards, phones, chips pop with easeOutBack 1.8 to 2 over 0.5 to 0.55 s, siblings 0.12 to 0.28 s apart |
| Moves | camera and cursor on easeInOutCubic; camera 1 to 1.6 s per key, max zoom 2.6x; cursor 0.4 to 0.6 s per hop |
| State changes | damped spring bump from 0.86 to 0.9 up to 1 (damping 7, frequency 2.2 to 2.4) |
| Scene change | the only transition: 0.3 s overlap, outgoing fades over 0.35 s (easeInCubic) while lifting 16 dp, with a whoosh |
| Click | 0.3 s: cursor shrinks 12%, blue ripple 6 to 24 dp, the button dips 6 to 8%, click sound, then a 0.6 s rest |
| Typing | 0.045 s/char in forms, 0.038 in a hero prompt, 0.032 in an assistant; block caret blinking at 1 Hz; one key tick per character |
| Doodles | round-capped ink pen strokes 2.2 to 2.8 dp (strike 5 dp) that draw on: strike, underline, loop, arrow, sparkle, tick, star, yellow marker sweep. Two or three per scene, each aimed at a measured word or UI element, each with a scribble sound |
| Pacing | promo scenes 3.6 to 5.6 s, tutorial steps 6.5 to 13 s; one idea per scene; every final state holds still at least 0.8 s |
| Sound | 112 BPM maj9 bed with a groove for promos, 96 BPM calm bed for tutorials; whoosh, click, pop, key tick, scribble, chime on the picture; soft clip, -1 dBFS peak, aim -16 LUFS |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

shared-product-motion-video is a skill published in the GitHub repository Desquared/agents-rules-skills (4 stars, last pushed 13d ago), licensed MIT. It adds 180 tokens to every session and 2,706 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-30.
