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.

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 | $0.00062 | $0.00402 |
| Opus 5.5 | $0.00025 | $0.00161 |
| Sonnet 5.5 | $0.00012 | $0.00080 |
| Haiku 4.5 | $0.00006 | $0.00040 |
Grade A, and why
czml-distance-scaling 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.
What it actually says
CZML Distance-Based Scaling & Visibility
- "scaleByDistance":
{ "nearFarScalar": [nearDistance, nearScale, farDistance, farScale] }— on "billboard", "point", "label", or "model", linearly interpolates a scale multiplier betweennearScale(atnearDistancemeters from the camera) andfarScale(atfarDistancemeters), clamped outside that range. It multiplies the graphic's own size (e.g. "pixelSize"/"scale"). - "distanceDisplayCondition":
{ "distanceDisplayCondition": [nearDistance, farDistance] }— on the same graphics properties (or the shape itself), only renders the entity while the camera is betweennearDistanceandfarDistancemeters away.
Example: a billboard that scales down and disappears with distance

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.

czml-distance-scaling is a skill published in the GitHub repository CesiumGS/cesiumjs-ai-starter-app (10 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 62 tokens to every session and 402 once invoked, about $0.0002 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 2026-08-31.

Compile a LaTeX document and fix every error plus aesthetic issue (overfull/underfull boxes, widows, alignment, fonts) for a clean PDF and log. Use this instead of running pdflatex/latexmk manually — it avoids the latexmk stale-log trap and silent grep failures on binary log output, and it reformats rather than…
