     shadertool [选项] <SkSL 代码>
 
 示例  
-    `shadertool "void main() { sk_FragColor = vec4(sin(sk_FragCoord.x * 0.01), 0, 0, 1); }"`  
-        使用默认参数（320×180，1秒，15fps）渲染一段红色水平波纹动画。
+    shadertool """
+    uniform float u_time;
+    uniform float2 u_resolution;
 
-    `shadertool --width 256 --height 256 --duration 2.0 --fps 20 "void main() { sk_FragColor = vec4(fract(sk_FragCoord * 0.02), 1); }"`  
-        以 256×256 分辨率、2 秒时长、20 帧每秒渲染一个彩色格点动画。
+    half4 main(float2 coord) {
+        return half4(
+            1.0,
+            sin((coord.y / u_resolution.y + u_time) * 3.1415926 * 2) * 0.5 + 0.5,
+            coord.x / u_resolution.x,
+            1.0
+        );
