web-shader-extractor

web-shader-extractor is a skill for Claude Code, Codex from JiuTian-dev/SupplyChainCortex. It costs 89 tokens per session (1,783 once invoked), scanned A, original, no licence file.

A skill for extracting WebGL, Canvas, and shader effects from web pages and moving them into a standalone JavaScript project. WebGL and Canvas are browser technologies for drawing interactive graphics.

In plain words
What is it for?
It helps extract animated backgrounds, Canvas effects, WebGL effects, and shader code from websites and port them to native JavaScript projects.
Why use it?
It reduces the manual work of locating, untangling, and separating visual-effect code from an existing website. It is aimed at reuse rather than ordinary page-content extraction.

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

web-shader-extractor scanned grade A with 1 finding 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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/fetch-rendered-dom.mjs, scripts/scan-bundle.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
