Agents cite line ranges like GitVcsDriverCore.ts:3798-3803. Chat only parsed single positions, so a range rendered as plain, unclickable code. A Markdown link to one, [x](/abs/http.ts:42-64), was not a file link at all. On one of our machines, Claude wrote 648 such ranges in two weeks; 1,633 of its file references used a single line.
splitFilePathPosition in @t3tools/shared now reads :42-64 and #L42-L64. The link opens at the first line and keeps the end line, so the pill label reads L42–64. Editor targets and copied paths stay path:42, which every editor understands. Web and mobile both use these helpers, so both pick it up. A port range like port:3000-3010 still isn't a file.
Highlighting the whole range in the file viewer is a separate change; this opens at the first line.
The same message in a real thread.
Before: the range is plain code.
Before: packages/shared/src/orchestrationV2PendingBackgroundWork.ts:290-306 renders as plain code
After: it is a file link labelled L290–306. Clicking it opens the file at line 290.
After: the range renders as a file link labelled L290–306 and opens the file at line 290
Mobile builds its label from the same parser. It is covered by the shared tests but was not checked on a device.

Macroscope's review found this PR approvable — File links with line ranges now navigate to the first line and preserve the range in their labels. The change is limited to link parsing and presentation through existing navigation paths.

File-link parsing now supports line ranges in path suffixes and hashes. Labels display valid ranges, and web metadata carries the end line.

Parsed metadata includes a valid end line, labels display ranges, and label matching compares end lines. Mobile inline-link matching recognizes range suffixes.

The description explains the problem and change, provides before-and-after screenshots, and states that mobile was not checked on a device. It does not include a separate scope-and-approval section or specific test results, but it gives enough detail to assess the focused fix.

@coderabbitai Re the outside-diff comment on markdownLinks.ts:182-203 (hash ranges in inline file candidates): not changing it, for the reason in the mobile thread. A #L anchor in inline code was never a file link, single line or range. Markdown link destinations do handle #L42-L64, and agents write inline ranges as :42-64.

For best results, initiate chat on the files or code changes.

@juliusmarminge Understood. I won’t pursue inline #L support in this PR. The shared tests cover :42-64 inline candidates and #L42-L64 Markdown destinations.

| 5 | Learning: In apps/web/src/components/ChatMarkdown.tsx, the TypeScript/React Markdown pipeline uses remarkNormalizeLinksAndTagInlineCode to track link and linkReference ancestry. It adds dataInlineCode only to inlineCode nodes outside links. MarkdownCode requires node.properties.dataInlineCode before converting inline code into a file chip. Inline code in descriptive Markdown link labels therefore does not create a separate file action. |
