What problem does it solve? PrimeTween's API differs from DOTween in naming, lifecycle, and configuration, so developers often write incorrect tween code by assuming DOTween conventions. This Skill supplies design rules grounded in the PrimeTween 1.4.6 source so generated or reviewed animation code matches actual library behavior. ## Core Features & Use Cases - Factory and Handle Rules: Clarifies that Tween handles are non-reusable structs and that completed or stopped tweens must be recreated rather than replayed. - Sequence Composition Guidance: Explains Chain, Group, and Insert semantics for sequential, parallel, and absolute-time animation, contrasting them with DOTween's Append/Join vocabulary. - Lifecycle and Callback Safety: Covers target-bound OnComplete callbacks, destroyed-target detection, cancellation, async/await and coroutine waiting, and PrimeTweenConfig capacity tuning. - Use Case: When reviewing a Unity script that chains position and scale tweens with callbacks, load this Skill to verify the sequence structure, callback target binding, and cancellation handling against PrimeTween 1.4.6 source anchors. ## Quick Start Review my PrimeTween sequence code and check whether the callbacks, cycles, and cancellation handling follow PrimeTween 1.4.6 design rules.
