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 | $0.00067 | $0.00566 |
| Opus 5 | $0.00034 | $0.00283 |
| Sonnet 5 | $0.00013 | $0.00113 |
| Haiku 4.5 | $0.00007 | $0.00057 |
Grade A, and why
czml-polyline-volume 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 Polyline Volume
- "polylineVolume":
{ "positions": { "cartographicDegrees": [lon0, lat0, h0, lon1, lat1, h1, ...] }, "shape": { "cartesian2": [x0, y0, x1, y1, x2, y2, ...] }, "cornerType": "ROUNDED"|"MITERED"|"BEVELED", "material": { "solidColor": { "color": { "rgba": [r,g,b,a] } } }, "outline": true|false, "outlineColor": { "rgba": [r,g,b,a] }, "show": true|false }— extrudes the 2D "shape" polygon (defined in local X/Y meters, e.g. a box cross-section) along the 3D "positions" path. - "shape" is a flat list of 2D points describing one closed cross-section (e.g. a small square:
[-500, -500, 500, -500, 500, 500, -500, 500]), not repeated for each path position. - "cornerType" defaults to
"ROUNDED"if omitted.
Example: a beveled, outlined box-cross-section tube along a path

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-polyline-volume 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 67 tokens to every session and 566 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.

latex-compile
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…
nb-to-wolfbook
Convert Mathematica .nb or .m files to Wolfbook .wb format so they open and run in VS Code. Use when bringing existing .nb/.m files into Wolfbook, or to make an existing .wb bridge-safe.
sync-wb-nb
Propagate a change made in a Wolfbook .wb notebook into the paired .nb notebook so the two stay identical. Use immediately after every .wb edit.

Run heavy Wolfram Language (wolframscript) computations from Claude Code reliably, and diagnose the misleading "The product exited because of a license error". Use whenever invoking wolframscript on a non-trivial computation, when a wolframscript job dies with a "license error" despite a valid license, or when Wolfram…
cross-validate
Format a result, derivation, or numerical value for independent verification by a second model. Use when you want a cross-check on an important or contested result.
