renderer

renderer is a skill for Claude Code, Codex from skyciv/skyciv-ai-skills. It costs 35 tokens per session (3,111 once invoked), scanned A, original, MIT.

A browser-based JavaScript library for displaying SkyCiv structural models and analysis results in interactive 3D. It shows data but does not solve or store models.

In plain words
What is it for?
Use it for web pages, dashboards, embedded previews, or automated screenshots and reports that display SkyCiv model data.
Why use it?
It provides a way to present structural models or results without building a 3D viewer from scratch.

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

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.

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_model and analysis_results from the S3D.* API (see the s3d-api skill: S3D.model.get, S3D.file.open, S3D.results.get) and pass them into the renderer, or build/edit the s3d_model object 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 assume model.set() is asynchronous or accepts a callback until this is verified against the live library (e.g. by inspecting skyciv-renderer-dist.js directly 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.

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.
