Semantic Labels

When to Use

Use this skill when the user asks to label objects, assign semantic class/label metadata, configure semantic segmentation labels, or author SemanticsAPI overrides.

Inputs

Resolve inputs in this order: existing repository files and referenced snippets, explicit user request, then broader agent context.

• Target API surface: Python, C/C++, USD, or a combination.
• Prims to label, desired semantic class and label values, and whether labels should be authored directly or as override layers.
• Requested ground-truth outputs such as SemanticSegmentation or SemanticIdMap when the workflow includes rendering.
• Existing composition context: source asset path, inline USDA, sublayer, or runtime-loaded stage.
• Repository source snippets referenced below. Treat these snippets as the API source of truth.
