The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill provides tools to mutate USD stage files by adding sublayers and payloads, which involves processing external files and identifiers.
Ingestion points: Tool arguments in tools.yaml (e.g., stage_file, sublayer_path, payload_path) accept paths to external assets.
Boundary markers: None explicitly defined in the skill instructions.
Capability inventory: The skill has file-write capabilities through the dcc_mcp_openusd runtime to modify stage files.
Sanitization: The skill relies on the underlying pxr (usd-core) library for validation of USD structures and asset resolution.
[EXTERNAL_DOWNLOADS]: The skill requires external dependencies including dcc-mcp-core and the well-known pxr (usd-core) OpenUSD runtime. These resources are consistent with the vendor's provided tools and standard industry practices.
