One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
I need a spring animation spec for a hero banner expansion in Jetpack Compose that gives a noticeable, bouncy spring overshoot without using predefined Material theme tokens. Which `spring()` parameters (dampingRatio and stiffness) create a bouncy hero reveal?
| Checked | Without skill | With skill |
|---|---|---|
| Uses Spring.DampingRatioMediumBouncy for spring specification | Missed | Passed |
| Uses Spring.StiffnessLow for spring specification | Missed | Passed |

Advanced Compose visuals: M3 Expressive motion physics, AGSL shaders (Android 13+), Canvas / DrawScope, graphicsLayer effects. Loaded for advanced thesis (shader, expressive, M3 Expressive, AGSL, Canvas, holographic). Foundation:
../compose-motion/SKILL.mdcovers basics. Concise rules here. Deep-dive inreferences/.
| Need | API |
|---|---|
| Spring physics with bounce / overshoot | MotionScheme.expressive() (M3 Expressive) |
| Pixel-level shader | RuntimeShader + Modifier.graphicsLayer { renderEffect = ... } (Android 13+) |
| Generative drawing (paths, particles, fractals) | Canvas { drawScope -> ... } |
| GPU effects (blur, shadows, color filters) | Modifier.graphicsLayer { renderEffect = ... } or Modifier.blur(...) |
| Adaptive system materials (Material You glassmorphism) | Modifier.background(MaterialTheme.colorScheme.surfaceContainerHighest) |
| Liquid glass on Android | AGSL shader recipe (no native API like iOS yet) |
The 2025 Material 3 evolution introduces spring-based motion physics replacing fixed-duration tweens. New shape morphing API via androidx.graphics.shapes. New MotionScheme selectable on the theme. Aimed at hero moments, key interactions, brand-defining UI.
| Scheme | Personality | Use For |
|---|---|---|
MotionScheme.standard() | Calmer, less overshoot | Default for chrome, lists, navigation |
MotionScheme.expressive() | More overshoot, longer settle | Hero reveals, FABs, primary CTAs |
