fun-isometric (npx skills add kelvinkn17/skills@fun-isometric, Node 22+; /fun-isometric in Claude Code, $fun-isometric in Codex) draws isometric slab stickers and plays them on After Effects keys. It ships a no-dependency kit to copy into the project (fun.ts, motions.ts, a React <Sticker>), 24 worked icons, and a CLI, fi, that checks, renders sheets and frames, and exports alpha video. The craft it encodes is distilled in isometric-stickers; this node says who owns what and settles the conflicts.

Who owns what when it is installed

Job	Owner	This graph keeps
A playful animated icon, empty-state art, onboarding illustration or feature sticker	fun-isometric: draw, rig, `fi check`, `fi sheet`, export	whether it should move at all (animation-decision-framework); the palette, from the contract
A flat icon in a UI set, a glyph in a button	icon-systems / svg-creation	everything; a slab sticker is not an icon set
A mascot clip turned into vector	video-to-vector-pipeline	everything
A sticker inside a launch film	the film's engine (skill-router §5), the sticker as an exported alpha clip	register, cuts, the sound on its contact frames (sound-from-motion)

Without it installed, build to isometric-stickers as SVG (svg-animation) and say fun-isometric would have owned the job.

Conflicts, settled

Topic	fun-isometric	This graph	Settled
Entrance	pops from scale 0.2, turned −90°, on a bounce	never-scale-from-zero: 0.95 + opacity	A sticker's entrance is a character beat, so its pop stands. Menus, modals and toasts keep 0.95
Duration	123–180-frame loops at 60 fps (2–3 s)	duration-table: UI under 300 ms, onboarding hero 400–800 ms	Illustration time, not interface time: the action sits in the first second, the rest is the hold. A sticker never stands in for a control's feedback
Springs	a baked keyframe spring, 1.448 overshoot, 91 frames	spring-animations: stiffness and damping	Different engines. Never port its keys into a UI spring or the reverse
Idle motion	`wobble`, `sway` and `float` for faces and idle layers	delight-impact-curve: delight decays with frequency	Idle loops for one hero sticker on a rare screen. In a list or a frequent view, play once (`loop={false}`) and rest on `still`
Colours	`riso` inks by default	the contract (using-design-file)	The contract wins: `brand(accent, second)` from its tokens; `riso` only when there is no contract
Corners	miter joins, butt caps, sharp	pov (this install: "pointy shapes are off-brand")	pov wins on a forked install: `round: true` on every part
Grey	a `grey` slot	pov (this install: no grey inside illustrations)	Map `grey` to a pastel of the palette on this install
Shape count	three to six parts per hero object	pov (this install: about 15 shapes)	Different units: parts are slabs, shapes include the detail on them. Both budgets apply
Format	canvas live, or alpha webm / HEVC mp4	svg-animation: native SVG first	Canvas or video when the slab stack and runtime palette swaps matter; SVG when the file must be editable markup. Give the canvas an accessible name (`label`)
Dependencies	none for the runtime; Bun, ffmpeg and a self-installing Playwright Chromium for `fi`	dependency-discipline	The kit is copied source, so it passes. Tell the user before the first `fi` run: it downloads a Chromium into `~/.cache/fun-isometric`

Gotcha

Its default inks are a full six-accent palette. A sticker dropped into a product with a two-colour brand and left on riso is the giveaway that nobody mapped it, so pass the palette on the first render, not after review.
