Problem

When an agent asks a question in Hebrew or Arabic (Claude's AskUserQuestion, or any user input request), the question card shows its options left to right on web, desktop and mobile. Hebrew labels and descriptions sit on the left, the period lands at the start of the sentence, and mixed lines such as תנסה ב-t3, 3. אחד שתיים שלוש or גרסה 2.5 של Node.js (בערך 40%) come out scrambled. The citation chip in the composer and its comment box have the same problem.

#22777 fixed this for chat messages, and the web card's question sentence already follows it because it renders through ChatMarkdown. The header, the collapsed preview, the options and the citation chip are plain text, so they don't.

To reproduce, ask an agent to ask you a question with options in Hebrew, or cite a Hebrew sentence and add a Hebrew comment.

Change

  • Web and desktop question card (ComposerPendingUserInputPanel):
    • Every text line (header, collapsed preview, option label, description) gets dir={textDirection(text)}, the same pattern as SidebarThreadRow and ChatHeader, so each line reads in its own direction.
    • The card picks one direction for the whole question set: the same word-majority rule over every question's header, question, labels and descriptions. That dir goes on the card, so the radios, shortcut numbers, header and counter sit on the matching side, and every line aligns to that side.
    • Because it is decided once per set, the card never flips while you step through the questions. A mostly English set stays left to right even when one question is Hebrew, and a mostly Hebrew set stays right to left even when one question is English.
  • Citation (AssistantCitationChip, AssistantCitationCommentEditor): the comment textarea, the composer chip label, and the quote and comment in the citation popover get dir={textDirection(text)}. Text direction only.
  • Mobile (PendingUserInputCard): the same rule as web. The card computes one direction for the whole question set, and every line aligns to that side.
    • The header, option labels, and descriptions get direction and writingDirection styles for their own reading direction, so punctuation lands at the correct end.
    • React Native treats textAlign: left/right as start/end on a line whose direction is rtl, so the card picks the value that lands on the set's side physically.
    • The question sentence goes through the Enriched Markdown renderer. SelectableMarkdownText now passes the fork's writingDirection prop and a paragraph textAlign through, so the question follows the same side.
  • To let mobile use the word-majority rule from fix(web): Arabic and Hebrew text reads and navigates right to left #22777, textDirection now lives in @t3tools/shared/textDirection. apps/web/src/textDirection.ts re-exports it, so existing web imports and tests are untouched.

Not touched: on mobile, the custom answer field is the native composer, which #23587 covers. #23587 also touches the Enriched Markdown direction props, so whichever lands second needs a small rebase.

Scope and approval

This is a follow-up to merged #22777 for #13622. It applies the same rule to the surfaces that change didn't reach. No new heuristic. #15320 included this card before it was closed in the PR cleanup.

Verification

  • Browser test ComposerPendingUserInputPanel.direction.browser.test.tsx: a mostly Hebrew set computes to rtl on the card and its lines, an English option inside it stays ltr, and a mostly English set keeps the card ltr on its Hebrew question. The first test fails without the whole-set direction.
  • vp run check:changed: format, lint, knip, typecheck, and tests pass.
  • Screenshots are from the running apps: the web client from vp run dev at 2x, and the iOS development build on an iPhone 17 simulator (iOS 27) paired to the same dev server, at 3x. Claude Sonnet 5.5 asked the questions with AskUserQuestion. "Line by line" is the previous commit on this branch, "Whole set" is the current head.
  • Not checked: Android rendering. The direction style follows React Native's Android text layout code, but I didn't run it on an emulator.

Approvability

Verdict: Approved at 64ac893

Macroscope's review found this PR approvable — This is a contained RTL/LTR rendering fix for agent question cards across web and mobile, with the existing direction heuristic moved to shared code and focused browser coverage added. Runtime effects are limited to text alignment and ordering; no product defaults, static-analysis suppressions, schema changes, or sensitive areas are involved.

Walkthrough

The shared package now exports text direction inference. Web and mobile chat components use inferred direction for pending questions, options, citation text, and citation comments. Web option rows use logical start alignment, and a browser test checks direction in the pending input panel.

Changes: Text direction rendering

Layer / File(s) Summary
Shared text direction utility
packages/shared/src/textDirection.ts, packages/shared/package.json, apps/web/src/textDirection.ts
The shared package adds and exports TextDirection and textDirection. The web module re-exports the shared implementation.
Pending input direction
apps/web/src/components/chat/ComposerPendingUserInputPanel.tsx, apps/mobile/src/features/threads/PendingUserInputCard.tsx, apps/web/src/components/chat/ComposerPendingUserInputPanel.direction.browser.test.tsx
Web and mobile components apply inferred direction to question text, option labels, and descriptions. Web option rows use text-start. The browser test checks text direction and confirms the option button remains left-to-right.
Citation text and comment direction
apps/web/src/components/chat/AssistantCitationChip.tsx, apps/web/src/components/chat/AssistantCitationCommentEditor.tsx
Citation labels, quoted text, optional comments, and the comment textarea receive direction inferred from their text.

Assert rendered direction instead of dir attributes.

These assertions repeat the assigned attributes. They do not confirm the browser’s resulting direction or alignment. Use browser assertions such as expect.element(...).toHaveCSS(...), and check the option layout where direction matters. As per coding guidelines, “Test meaningful logic or observable behavior. Do not render components to static markup to assert props or attributes”; browser tests also “assert through expect.element or vi.waitFor.”

Exercise the collapsed preview in this browser test.

The test leaves the panel expanded, so it does not render or assert the changed collapsed question preview. Toggle the trigger before asserting question direction, or add a separate collapsed-state test.

thanks @Dananz. your fix correctly reuses the existing direction heuristic and keeps the option rows and controls in place. i kept all your commits and merged current main into the original branch at 96be4481882ab29b11f5dbb6b5cdaf3db185dc3e. the conflict resolution preserves main's redesigned header, separator, radios, spacing and shortcut column while retaining direction on headers, labels, descriptions and collapsed previews. no new heuristic or production scope was added.

verification:

  • reproduced the browser regression on main: the hebrew header computed to ltr instead of rtl.
  • blacksmith vp run check:changed passed format, lint, both knip passes, typecheck of 34 affected packages and 12 tests. focused direction, navigation and heuristic tests also passed separately.
  • system chrome against the running dev app: a real codex question with english-leading hebrew and arabic options renders rtl; collapse/reopen and selecting/submitting the hebrew option work through the provider path. screenshots use matching question data and main's component before versus this head after.
  • unverified this run: native ios/android rendering, electron shell and remote/tunnel connections.

@Dananz: one nonblocking upstream android gap remains. react native 0.88 ignores writingDirection; direction aligns these text nodes but android's first-strong paragraph ordering can still misread english-leading rtl prose. this needs an android-supported native paragraph direction mechanism in a follow-up. i kept this takeover focused rather than patching the native renderer or inserting hidden bidi characters into displayed answers. ios retains your original implementation and evidence.

before, expanded:

main question options before direction fix

after, expanded:

question options after direction fix

before, collapsed:

main collapsed question before direction fix

after, collapsed:

collapsed question after direction fix

collapse reopen and submit the hebrew answer

final status: all 6 reported pr checks are green, conflict check is mergeable, and two independent reviews approve 96be448188 with the android limitation above. screenshots render in the github mirror; git.cafe displays external media as links. the uploaded mp4 bytes match the inspected clip and play in chrome, but inline video playback in the forge comment is unavailable.

@maria-rcks thanks for taking this over and for the approval. I pushed three more commits after your merge, so it needs another look:

  • e21aaf8 Citations: the comment box, the composer chip, and the quote and comment in the citation popover now read Hebrew and Arabic right to left. Text direction only.
  • 12a9d52 Web question card: one direction for the whole question set, by the same word-majority rule. Line by line, the card flipped sides while you stepped through a mixed set. Now a mostly Hebrew set stays right to left even on an English question, and a mostly English set stays left to right on a Hebrew one. Each line still reads in its own direction.
  • 88ccf5e Mobile: the same rule, the question sentence included. It passes the Enriched Markdown fork's writingDirection and a paragraph textAlign through SelectableMarkdownText. This overlaps fix(mobile): respect prose direction in chat and composer #23587 a little, so whichever lands second needs a small rebase.

vp run check:changed passes (format, lint, knip, typecheck, tests). Codex reviewed the diff and caught the collapsed preview not following the set's side, fixed in the same commit. On your Android note: I still haven't run it on an emulator. React Native swaps textAlign left and right on rtl lines on iOS, and I'd rather check Android in a follow-up than guess. Happy to do it here if you prefer.

"Line by line" is the commit before these, "Whole set" is the head.
