#786 fix: replace verbose docstrings with short descriptions in File, Dir, and DataFrame JSON schemas Pull request opened by AdilFayyaz Motivation Pydantic's

model_json_schema()

includes the full class docstring as the description field, which leaked multi-line implementation docs into

LiteralType.metadata

affecting both Pydantic model and dataclass workflows (via PydanticSchemaPlugin). Summary • Set

json_schema_extra

on File, Dir, and DataFrame to override the docstring-derived description with a concise one-liner • Added

x-flyte-type

extension key ("file", "dir", "dataframe") to each schema for type identification Test Plan • Run

pytest tests/flyte/type_engine/pydantic/test_file_literal_type_metadata.py -v

• All 6 tests should pass, covering both the Pydantic and dataclass schema generation paths flyteorg/flyte-sdk
