usd-tools skillA

usd-tools is agent-read markdown (skill) from dcc-mcp/dcc-mcp-core: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dcc-mcp/dcc-mcp-core/usd-tools@git:20260505.5c57b27
Exact content
mdr add dcc-mcp/dcc-mcp-core/usd-tools@sha256:b3fbe3c91e0aba69

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
