Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.06965 |
| Opus 5.5 | $0.00032 | $0.02786 |
| Sonnet 5.5 | $0.00016 | $0.01393 |
| Haiku 4.5 | $0.00008 | $0.00696 |
Grade A, and why
cesiumjs-camera scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CesiumJS Camera & Navigation
Baseline: CesiumJS v1.144 -- ES module imports (
import { ... } from "cesium";)
Camera Fundamentals
Access via viewer.camera. The camera has a position (Cartesian3 in world
coords), orientation vectors (direction, up, right), and a frustum.
All angles are radians.
Read-only computed properties: positionWC, positionCartographic,
directionWC, upWC, rightWC, heading (0 = north, clockwise), pitch
(negative = down), roll, transform, viewMatrix, inverseViewMatrix.
Events: moveStart / moveEnd fire when movement begins/ends. changed
fires when the camera moves by more than percentageChanged (default 0.5).
City views are more realistic with 3D buildings. For production skyline, street-level, or urban panorama views, use a tileset that is actually available in the target environment.
Cesium.createOsmBuildingsAsync()and Google Photorealistic 3D Tiles are ion-entitlement-backed; avoid them in public or no-token examples unless the caller explicitly asks for those services. For portable examples, use an OpenStreetMap/ArcGIS basemap, visible markers, public URL-backed 3D Tiles, or a higher-altitude city overview.
Altitude & Orientation Guidelines
Choose altitude and pitch to match the scale of the feature you want to show:
| View type | Altitude (m) | Pitch (deg) | Notes |
|---|---|---|---|
| Tourist / monument standoff | 50 -- 500 | -5 to -20 | Camera at near-ground level, offset laterally from the landmark. Subject fills the frame with sky visible above. Use lookAt with HeadingPitchRange pitch near -10°. Never place the camera directly overhead at this range. |
| Landmark close-up | 500 -- 1,500 | -25 to -35 | Individual buildings/structures fill the frame. Use lookAt with appropriate range. |
| City panoramic / skyline | 800 -- 1,500 | -10 to -20 | For viewing a skyline from across a river or bay. Position camera to the side, face the city. Use an available 3D Tiles source only when the environment provides one. |
| City overview | 2,000 -- 5,000 | -35 to -50 | Urban grid, rivers, and parks clearly visible |
| Metro / regional | 8,000 -- 20,000 | -60 to -90 | Entire metro area or geographic feature |
| Canyon / cliff rim | 50 -- 300 above rim | -15 to -25 | Use steeper pitch to reveal depth below. Near-horizontal (-5) looks flat across terrain. Add wall/rim entity overlays and a river polyline to make canyon structure visible. |
| Country / continent | 500,000 -- 5,000,000 | -90 | Political boundaries, coastlines |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cesiumjs-camera is a skill published in the GitHub repository CesiumGS/cesiumjs-skills (191 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 80 tokens to every session and 6,965 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
