cesiumjs-3d-tiles SKILL.md skillA
cesiumjs-3d-tiles from cesiumgs/cesiumjs-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cesiumgs/cesiumjs-skills/cesiumjs-3d-tiles@git:20260827.49e0612Pins git:20260827.49e0612 in mdr.lock. Pin the fingerprint instead.

CesiumJS 3D Tiles - Cesium3DTileset, compressed and CAD-style glTF content, MVTDataProvider, UrlTemplate3DTilesDataProvider, styling, metadata, feature picking, voxels, point clouds, I3S, Gaussian splats, clipping. Use when a task involves loading 3D Tiles or Mapbox Vector Tiles, draping vector tiles on terrain, rendering KHR meshopt/CAD content, styling or querying features, working with voxels or point clouds, or clipping spatial data.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CesiumJS 3D Tiles
Version baseline: CesiumJS v1.144 (ES module imports, async factory methods).
## Loading a Tileset
Always use async factory methods -- never call the constructor directly.
For public/no-token examples, prefer URL-backed tilesets such as CesiumGS sample
tilesets. `fromIonAssetId`, `createOsmBuildingsAsync`, and Google
Photorealistic 3D Tiles require external entitlements; use them only when the
caller explicitly asks for those services and the runtime is configured for
them.
```js
import { Cesium3DTileset, HeadingPitchRange, Math as CesiumMath } from "cesium";
// From a URL
const tileset = await Cesium3DTileset.fromUrl(
"https://example.com/tileset.json",
{ maximumScreenSpaceError: 16 }, // lower = higher quality
);
viewer.scene.primitives.add(tileset);
await viewer.zoomTo(tileset, new HeadingPitchRange(
0.0, CesiumMath.toRadians(-25.0), tileset.boundingSphere.radius * 2.0,
));
```
CesiumJS 1.143 applies standalone model loading to glTF embedded in tilesets.
Read the [glTF compatibility matrix](../cesiumjs-models-particles/REFERENCE.md)
for automatic `KHR_meshopt_compression`, CAD extension behavior, and the unsupported planar-fill boundary.

How to install
mdr add cesiumgs/cesiumjs-skills/cesiumjs-3d-tiles@sha256:0cdeb63029716bf2The line at the top of this page pins the label git:20260827.49e0612, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
