Sagents.FileSystem.FileMetadata (Sagents v0.8.0-rc.6)

Copy Markdown

Metadata for a file entry in the virtual filesystem.

Tracks size, timestamps, checksum, and mime_type. The mime_type field exists so multi-modal LLMs and downstream tools can route binary content (PDFs, images) correctly even when the path extension is ambiguous or absent.
