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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00065 | $0.00768 |
| Opus 5 | $0.00032 | $0.00384 |
| Sonnet 5 | $0.00013 | $0.00154 |
| Haiku 4.5 | $0.00006 | $0.00077 |
Grade A, and why
czml-corridor 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 11d 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 Corridor
- "corridor":
{ "positions": { "cartographicDegrees": [lon0, lat0, h0, lon1, lat1, h1, ...] }, "width": <number>, "cornerType": "ROUNDED"|"MITERED"|"BEVELED", "height": <number>, "extrudedHeight": <number>, "material": { "solidColor": { "color": { "rgba": [r,g,b,a] } } }, "outline": true|false, "outlineColor": { "rgba": [r,g,b,a] }, "show": true|false }— a shape defined by a centerline ("positions") and "width" (the distance between its edges), conforming to the globe's curvature. - "cornerType" defaults to
"ROUNDED"if omitted; set it explicitly when the intent specifies a corner style. - Omit "height"/"extrudedHeight" for a corridor clamped to the ground; set "extrudedHeight" to give it volume above "height".
Example: three corridors, one per corner type

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-corridor is a skill published in the GitHub repository CesiumGS/cesiumjs-ai-starter-app (7 stars, last pushed 14d ago), licensed Apache-2.0. It adds 65 tokens to every session and 768 once invoked, about $0.0003 per session on Opus 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.
