Separate simple front matter from Markdown content and verify delimiter closure and renderer/tooling dependency before publishing.

Raw front matter

ReadyThis inspector recognizes a top-of-file --- block and simple key: value lines. It does not claim to parse the full YAML specification, nested objects, anchors, or custom tags.

Renderer handoff review

Review the Markdown you will actually publish

The review follows the source or generated Markdown for this tool, checks structural handoff risks, and keeps CommonMark/GFM/host-specific boundaries visible before copy or export.

Handoff findings

Copyable handoff summary

Review summary will appear here.

CommonMark defines the core syntax, while GitHub Flavored Markdown and publishing systems add extensions such as tables, task lists, autolinks, footnotes, front matter and renderer-specific raw-HTML behavior. This review is local and never fetches links.

What this Markdown result proves

Front matter is metadata understood by specific static-site/document systems rather than CommonMark syntax.

What to review before handoff

Verify both delimiter closure and whether the destination system supports the metadata keys and YAML features you use.
