Descriptive file links such as This function [validates the input](/repo/src/example.ts:12). lost their authored prose in web/desktop and both mobile renderers. Keep the prose and its formatting beside the existing destination chip; filename/path labels and inline-code chips retain their compact presentation. Labels with a different line or column stay visible. Web selection copy retains the authored inline-link Markdown, and native copy reconstructs the descriptive label and destination even when Android collapses the chip into an image.

closes #10787. closes #10794. Rebuilt against current main after #10794 was closed for the V2 transition.

Verified with a real Codex gpt-6.1-sol response in an isolated project: matching wide/narrow layouts, bold labels, opening the same file destination, selection copy equal to the provider's original Markdown, copy/paste, and message copy. Blacksmith passed 250 tests across four existing Markdown test files, scoped lint with zero errors, formatting, and client-runtime/web/mobile typechecks. Native mobile UI and native Electron actions remain unverified; desktop uses the changed web renderer.

Review correction: the mobile fallback uses alt text only inside file-link labels, preserving the existing image renderer for external and other links. Blacksmith passed 86 existing mobile Markdown tests, mobile typecheck, scoped lint (0 errors; 24 existing warnings), and formatting. Native mobile rendering remains unverified.

before: wide response discards descriptive file-link labels

after: the same wide response retains prose and bold labels beside destination chips

before: narrow response discards descriptive file-link labels

after: the same narrow response retains descriptive labels and filename chips

Recording: opening the file destination, copying the selected response as Markdown, pasting its authored labels, and copying the message. Leading idle time is trimmed; the interaction is retained. GitHub strips external video embeds, so this uploaded MP4 opens as a link.

📝 Walkthrough

Walkthrough

Web and mobile Markdown renderers retain descriptive text in file links while displaying file chips. A new helper identifies labels that match file-link destinations. Mobile text runs also preserve authored Markdown for context-copy ranges.

Changes

File-link rendering and copy

Layer / File(s)	Summary
File-label matching `packages/client-runtime/src/markdownLinks.ts`, `packages/client-runtime/src/markdownLinks.test.ts`	Added `isMarkdownFileLinkLabel` to compare normalized labels with parsed file-link destinations. Tests cover paths, positions, and label variations.
Preserve rendered labels `apps/web/src/components/ChatMarkdown.tsx`, `apps/mobile/src/features/threads/ThreadFeed.tsx`	Web and mobile renderers keep descriptive link content alongside the file chip. When a label matches the destination, they render the chip without the original label. In mobile file links, images render as alt text or title instead of media.
Preserve mobile source for copying `apps/mobile/modules/t3-markdown-text/src/nativeMarkdownText.ts`, `apps/mobile/src/lib/nativeMarkdownText.test.ts`	Mobile text runs retain source Markdown for copy ranges. Tests cover repeated descriptive links, collapsed and expanded chips, filename labels, and formatted labels.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Low

Merge Risk: 🔵 Low · up to 20dda

Image-only labels on file links in the mobile Markdown renderer lose their label text and copy content. This is a narrow edge case, and the file chip and destination still work. It can be followed up and does not block the rest of the change.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 90002

The changes preserve descriptive labels and copy content without an observed increase in file-opening permissions. Risk is limited, but native selection behavior and complete downstream coverage remain unverified.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The inspected exposure is confined to Markdown display, existing file/media actions, and user-initiated clipboard output. No new privilege or destination authority was established in these paths; complete dependent coverage remains unresolved.

Trust Boundaries and Controls

observed — Mobile images inside links now render alt/title text rather than invoking the image callback. Other mobile images retain existing source classification. Preserved web children can invoke the existing image renderer, which still selects Direct, WorkspaceFile, or fallback handling; this is new reachability from that label location, not a new image authority.

Resilience and Maintainability Implications

observed — Android updates the installed sanitizer configuration when serialized ranges change. Any overlapping partial selection expands to the range's complete sourceText. Source-level synchronization is supported, but rapid native updates and partial-selection product semantics remain unverified.

Include rendered breaks in the reconstructed link label.

When a descriptive link contains a soft_break, nodeTextContent(node) joins the surrounding words without a separator. appendNode renders a space, but sourceText copies the joined words. For [check\nthis file](/repo/example.ts), the displayed label and copied label differ. Build the copy label with the same break handling as the child runs.

The source-label reconstruction added in b6f2352395 preserves soft and hard breaks, so copied words remain separated. Focused break cases are being checked in the existing native Markdown tests.

@maria-rcks Thanks for the fix. The supplied code uses fileLinkLabelMarkdown(node) to preserve soft and hard breaks in sourceText, so copied words remain separated. This addresses the finding. I have not verified the test results.

Written by gpt-6.1-sol on behalf of Maria

This path already skips file-chip conversion for code inside links. remarkNormalizeLinksAndTagInlineCode tracks link/linkReference ancestry (ChatMarkdown.tsx:679-698) and adds dataInlineCode only when insideLink is false. MarkdownCode requires that property before converting a path to a chip (line 3259). A descriptive label therefore retains its code text and the outer file destination. No code change is needed.

CcoderabbitaiBotOct 4, 2026

@maria-rcks, you are correct. remarkNormalizeLinksAndTagInlineCode leaves inline code inside link and linkReference nodes untagged. MarkdownCode requires dataInlineCode before converting a path into a file chip.

The supplied code therefore preserves the descriptive code text without creating another file action. I missed the existing guard. No code change is needed, and I withdraw this finding. Thanks for the clarification.

It adds dataInlineCode only to inlineCode nodes outside links. MarkdownCode requires node.properties.dataInlineCode before converting inline code into a file chip.

Preserve labels that specify a different position.

For [example.ts:99](/repo/example.ts:12), this code removes :99 and classifies the label as redundant. All three renderers can then hide the authored line number and show only a chip for line 12. Compare an explicit label line and column with the destination position before omitting the label.

Treat an image-only file-link label as descriptive.
For [![diagram](image.png)](/repo/a.ts), nodeTextContent returns an empty label because the image text is in alt. isMarkdownFileLinkLabel treats that empty label as redundant. Native rendering emits only the file chip, and selection copy cannot use the new image-label serialization.

MarkdownImage then renders “Open docs” instead of the linked image. Limit the alt-text substitution to file-link labels; keep the existing image renderer for other links. (raw.githubusercontent.com)

Note

Written by gpt-6-astra on behalf of Maria

Fixed in 20ddaf4b94. The link context now distinguishes file labels from other links. Only file-link images use alt text; external and other links retain the existing image renderer. Inline-code label handling remains active for all links. Blacksmith passed 86 existing mobile Markdown tests, mobile typecheck, scoped lint and formatting. Native mobile UI remains unverified.

@maria-rcks The supplied code confirms the fix. MarkdownImage uses alt text or title only for file-link labels. External and other links retain props.renderImage. MarkdownInlineCode still handles labels inside all links.

Native mobile UI remains unverified, as you reported.

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.
