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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 25 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00035 | $0.03111 |
| Opus 5 | $0.00017 | $0.01555 |
| Sonnet 5 | $0.00007 | $0.00622 |
| Haiku 4.5 | $0.00003 | $0.00311 |
Grade A, and why
renderer 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.
How it starts
The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Renderer Agent
You are an agent that incorporates the SkyCiv 3D Renderer into web-based solutions. Unlike the S3D.* API namespaces (server-side, called via HTTP), the renderer is a client-side JavaScript library that runs in the user's browser to visualize an s3d_model and its analysis results in interactive 3D.
Use this skill whenever a solution needs to show a structural model or its results — a viewer page, a results dashboard, an embedded model preview, or an automated screenshot/report pipeline.
Relationship to the API: The renderer does not solve or store models — it only displays them. Get the
s3d_modelandanalysis_resultsfrom theS3D.*API (see thes3d-apiskill:S3D.model.get,S3D.file.open,S3D.results.get) and pass them into the renderer, or build/edit thes3d_modelobject directly client-side.
Setup
Include the renderer script and a container element with a defined size (the renderer sizes itself to its container, so the container must not be 0×0):
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<script src="https://api.skyciv.com/dist/v3/javascript/skyciv-renderer-dist.js"></script>
</head>
<body>
<div id="renderer-container" style="width: 100%; height: 500px; position: relative;"></div>
<script src="/path/to/initRenderer.js"></script>
</body>
</html>
Pin a specific version instead of the latest skyciv-renderer-dist.js for production stability if a versioned build is available.
Initialization
const viewer = new SKYCIV.renderer({
container_selector: '#renderer-container',
});
const s3d_model = {}; // from S3D.model.get / S3D.file.open, or built directly
viewer.model.set(s3d_model);
viewer.model.buildStructure();
viewer.render();
Nothing is drawn until viewer.render() is called — always call it after model.set + buildStructure, and again after any subsequent update.
Open question, not yet verified: a live UI that regenerates and re-renders the model repeatedly (debounced input-driven preview) has been observed to intermittently show a stale/unchanged view after the first render, and separately, passing a second (callback) argument to
model.set()was tried as a fix and instead broke rendering entirely (nothing displayed at all) - so that is confirmed not the right fix and must not be reintroduced. The root cause of the original staleness symptom is still unconfirmed - do not assumemodel.set()is asynchronous or accepts a callback until this is verified against the live library (e.g. by inspectingskyciv-renderer-dist.jsdirectly or testing in an actual browser). If you hit this symptom, treat it as unsolved and investigate fresh rather than reapplying either of the patterns above.
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.

renderer is a skill published in the GitHub repository skyciv/skyciv-ai-skills (7 stars, last pushed 8d ago), licensed MIT. It adds 35 tokens to every session and 3,111 once invoked, about $0.0002 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.
