Greptile Summary

This PR adds a new markdown-to-pdf extension that uses a custom pure-pdf-lib renderer to convert markdown into styled PDFs via Raycast's AI tool interface. The implementation is well-structured with good input validation, theme support, and font fallback handling. Two minor rendering issues are worth addressing before merge.

Confidence Score: 5/5

Safe to merge; both findings are P2 visual/UX issues that do not affect core functionality.

All remaining findings are P2: html: true causing silent content drop for embedded HTML (an edge case for typical markdown input) and missing table top-border on page breaks (a cosmetic defect). Neither blocks the primary user path.

extensions/markdown-to-pdf/src/lib/markdown.ts — html: true setting; extensions/markdown-to-pdf/src/lib/pdf/render.ts — table page-break border.

Vulnerabilities

No security concerns identified. PDF generation is local, link URLs are user-supplied and written directly to PDF annotations (expected behavior), and no secrets or credentials are handled.

Important Files Changed

Filename	Overview
extensions/markdown-to-pdf/src/lib/markdown.ts	Configures markdown-it with html: true, but the PDF renderer has no HTML token handler — raw HTML in markdown is silently dropped from output.
extensions/markdown-to-pdf/src/lib/pdf/render.ts	Custom PDF rendering engine; table top-border is not redrawn when a page break occurs mid-table, leaving an incomplete frame on the continuation page.
extensions/markdown-to-pdf/src/lib/pdf/markdown-model.ts	Markdown token parser that maps markdown-it output to typed PdfBlock structs; logic is sound and well-structured.
extensions/markdown-to-pdf/src/lib/normalization.ts	Input normalization and validation; uses a require() workaround for Raycast preferences (flagged in prior review threads).
extensions/markdown-to-pdf/src/lib/conversion.ts	Orchestrates content validation, layout normalization, directory creation, and PDF rendering; straightforward and correct.
extensions/markdown-to-pdf/src/tools/convert-markdown-to-doc.ts	Raycast AI tool entry point with confirmation dialog; well-typed and correctly structured.
extensions/markdown-to-pdf/package.json	Extension manifest with correct categories, Title Case preference labels, textfield types throughout, and all dependencies used.

Comment:
**HTML blocks silently dropped from PDF output**

`html: true` tells markdown-it to parse raw HTML tags in the markdown source, producing `html_block` and `html_inline` tokens. However, `parseMarkdownBlocks` in `markdown-model.ts` does not handle those token types, so any inline HTML the user includes (`<span>`, `<div>`, `<table>`, etc.) will be silently swallowed — no text reaches the PDF.

If HTML embedding is intentionally unsupported, set `html: false` so markdown-it treats `<…>` as literal text instead of silently discarding it:

```suggestion
export const markdown = new MarkdownIt({
  html: false,
  linkify: true,
  breaks: false,
});
```

How can I resolve this? If you propose a fix, please make it concise.

Comment:
**Missing top border when table spans a page break**

`ensureVerticalSpace` can insert a new page in the middle of the table loop. The top border (`rowIndex === 0` guard) is never re-drawn on the new page, so the continuation of the table starts without a top edge, leaving a visually incomplete table frame.

Consider tracking whether the current row is the first on its page and drawing the top border whenever a new page starts mid-table.
