Motion performance
Use when validating that an interaction stays within performance budget, animating cheap properties, avoiding jank, and never running costly decorative motion behind dense UIs.From its SKILL.md

Motion Performance
Responsibility: Keep interactions cheap and smooth. Protect dense work UIs from decorative cost.
When to invoke
- During implementation and at validation (step 13 of the root workflow).
Inputs
- The implemented interaction, its animated properties, and the page context.
Outputs
- Pass/fail against the performance budget, with required fixes.
Checks
- Animate
transform/opacity; avoid layout-triggering properties (width, height, top/left, box-shadow spread) unless justified. - No continuous decorative motion behind dense or data-heavy screens.
- Effects are composited and do not cause long frames or layout thrash.
- Off-screen and reduced-motion paths do no needless work.
- WebGL/canvas only when a simpler technique cannot meet the objective.
How it connects
- Reads
intelligence/performance guidance andregistry/cost metadata. - Reports to
implementation-validation; failures block the ship.
Notes
If an effect is expensive and the objective could be met more cheaply, send it back to
effect-selection. Performance is a selection input, not just a post-hoc check.
