shader-gen is a skill for Claude Code from Hhz0823/YoloCut. It costs 113 tokens per session (2,886 once invoked), scanned C, original, AGPL-3.0.

An AI tool that generates WebGL video effects, transitions, masks, and colour grades. WebGL is a browser technology for displaying animated graphics, while a mask controls which parts of an image appear.

In plain words
What is it for?
Use it to make filters, transitions, masks, reveals, zooms, push-ins, and colour grades for video.
Why use it?
It helps create custom visual treatments when built-in video effects do not fit the request. It can address changes between clips, reveal effects, zooms, and overall colour style.

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 C, and why

shader-gen scanned grade C 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 10d 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

- Generation always produces a library asset — never refuse because the timeline isn't ready.

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.
