# Interface: MarkdownSection

Defined in: [lib/classes/spooled\_markdown\_artifact.ts:60](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/lib/classes/spooled_markdown_artifact.ts#L60)

A section of a markdown document as returned by [SpooledMarkdownArtifact.md\_sections](../classes/SpooledMarkdownArtifact.md#md_sections).

## Remarks

Contains only line-range metadata — no content is fetched until the caller explicitly
requests it via `cat(bodyStartLine, bodyEndLine + 1)`.
