czml-corridor

czml-corridor is a skill for Claude Code, Codex from CesiumGS/cesiumjs-ai-starter-app. It costs 65 tokens per session (768 once invoked), scanned A, original, Apache-2.0.

A guide for defining CZML corridors: fixed-width shapes that follow a route on or above a 3D globe. CZML is a text format for describing objects shown in Cesium-based globe visualizations.

In plain words
What is it for?
Use it to create roads, strips, or other route-following areas with rounded, mitered, or beveled corners. It also covers ground-level and raised or solid corridors.
Why use it?
It removes guesswork when turning a centerline route into a corridor with a chosen width, corner shape, height, color, and outline.

Token cost

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.

Security

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.
