A bundled offline inspector for examining GLB files, a 3D model format, before using them in PlayCanvas.

It helps choose transforms and animation names, compare rigs, inspect characters or other assets, and detect cases that require a runtime check.

It reveals model dimensions, pivot and floor offsets, animations, joints, hierarchy, and whether bounds may change during animation.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00039	$0.00446
Opus 5.5	$0.00016	$0.00178
Sonnet 5.5	$0.00008	$0.00089
Haiku 4.5	$0.00004	$0.00045

Security

Grade A, and why

inspect-glb 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 24d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/inspect.mjs), 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.

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 it actually says

Inspect GLBs

Resolve scripts/inspect.mjs relative to this skill and run it before choosing transforms or animation names. Shortlist files; do not dump a whole asset pack into context.

node <skill-directory>/scripts/inspect.mjs public/models/*.glb

Read the output

dims, center, and groundOffset give the uniform scale input, the pivot offset, and the Y seat. Non-zero center.x or center.z means the model does not sit on its root.
boundsSource: trust bounds for placement only when it is vertices. accessor-minmax can over-estimate rotated nodes by up to 41 percent; incomplete or null means do not calibrate. boundsNotes gives the cause.
boundsPose: static and default-morph are the authored pose; bind is the skinned rest pose.
requiresRuntimeCheck flags morphs, skins, or partial decoding; confirm extents in the app.
nodePaths, clips, joints, and animationTargets feed configure-animation.

Bounds cannot prove facing. Confirm it in the running app and record the yaw with calibrate-model. Runtime meshInstance.aabb expands conservatively for morphs, so place static models from inspected bounds.

Compressed files

The inspector decodes plain, interleaved, quantized, and sparse buffers. For Draco, Meshopt, or external buffers, inspect a lossless scratch copy; do not use optimize, which applies extra transforms:

npx --yes @gltf-transform/[email protected] copy in.glb scratch.glb

The Engine cannot load EXT_meshopt_compression; see load-assets before shipping such files.

Changes

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.

inspect-glb is a skill published in the GitHub repository playcanvas/create-playcanvas (61 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 446 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
