from_path(path : String, content_type : String | Nil = nil, filename : String | Nil = nil) : self

Create from a file path with auto-detected content type

Content type is inferred from the file extension. You can override it explicitly, or provide a custom filename for the upload.

# Auto-detect content type from extension
file = Anthropic::FileUpload.from_path("src/tool.py")

# Override filename (e.g. for skill directory structure)
file = Anthropic::FileUpload.from_path(
  "src/tool.py",
  filename: "skill-name/tool.py"
)

# Override content type explicitly
file = Anthropic::FileUpload.from_path(
  "data/config",
  content_type: "application/json"
)
