gltf-transform

A tool for optimizing and processing GLB and glTF 3D model files. glTF is a format for storing and sharing 3D scenes, while GLB is its packaged form.

In plain words
What is it for?
Use it to optimize or post-process glTF and GLB models, including models using Draco or Meshopt compression.
Why use it?
It helps prepare 3D files for better use by applying processing or optimization steps.

Grade A, and why

gltf-transform 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 3d 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 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.
