### Self-check after using the skill

- 先用 tools/list.mjs 找现成特效，改调色板、种子、方向能解决就不新写 / Search tools/list.mjs first; a palette, seed or flip change beats a new effect
- 每一轮都渲染 contact.png 并亲眼看，至少改三轮 / Render contact.png every round and look at it; three rounds minimum
- tools/check.mjs 必须干净通过：不出画布、循环无缝、一次性特效结束时为空、不用 Math.random / tools/check.mjs passes clean: inside the canvas, seamless loops, one-shots end empty, no Math.random
- 导出时用 JSON 里的 fps 和 pivot，引擎里用最近邻过滤、不压缩 / Use the JSON's fps and pivot; nearest-neighbour filtering and no compression in the engine
- 环境循环（雨、火、灯光）首尾帧接得上 / Ambient loops (rain, fire, lights) wrap without a seam
- 不复刻具体游戏的角色、精灵或标志 / Never recreate a specific game's sprites, characters or logos
