+ Infrastructure skill — low-level OpenUSD scene inspection and validation:

+ read layer stacks, traverse prims, validate USD schemas. Use when working

+ directly with raw USD files (usda, usdc, usdz) or verifying USD compliance.

+ Not for Maya-specific USD export — use maya-pipeline__export_usd for that.

+ Not for full DCC pipeline workflows — use a domain pipeline skill instead.
