Cesium Skills

Writes native CesiumJS demos for the latest stable Cesium API (async terrain, 3D Tiles, imagery, WebGL2 shaders/effects). Use when creating or migrating Cesium Viewer, layers, terrain, Cesium3DTileset, models, CustomShader, PostProcessStage, materials, particles, or when old Cesium 1.x / WebGL1 demos break. Do not use for non-Cesium GIS or mars3d/SuperMap wrappers.

# Cesium Skills (native, latest API)

Generate **native CesiumJS** code aligned with the [official ref-doc](https://cesium.com/learn/cesiumjs/ref-doc/).

This skill ships **~185 modernized demo scripts** (`.js` only, no HTML) under [`examples/`](examples/), converted from Cesium-Examples `examples/cesiumEx` with async terrain/tileset, `baseLayer`, and WebGL2-oriented rewrites.

## Hard rules

1. **Native only** — call `Cesium.*` directly. No mars3d / SuperMap / custom SDK wrappers.
2. **Latest stable Cesium** — Ion CDN or `npm cesium`. Do not default to Cesium 1.98 paths.
3. **Modern async API** — prefer `fromUrl` / `fromGltfAsync` / `createWorldTerrainAsync` / `Terrain.fromWorldTerrain`. Never recommend `readyPromise` or `new Cesium3DTileset({ url })` / `new CesiumTerrainProvider({ url })` as the primary path.
4. **WebGL2 default** — never set `requestWebgl1: true`. Custom shaders follow [webgl2.md](webgl2.md).
5. **Container** — `div#map` unless the host project already differs.
6. **No default Ion basemap noise** — `baseLayer: false` + `baseLayerPicker: false`, then add imagery yourself. Do **not** use deprecated `imageryProvider: false`.
7. Prefer **Chinese section comments** when writing demos for Chinese users.
8. Prefer **Tianditu XYZ** as the sample imagery (placeholder `tk=`).
