feat(chat): restructure user bubble, drop role labels by seeones · Pull Request #1984 · Zoo-Code-Org/Zoo-Code

Related GitHub Issue

Closes: #1994

Description

Reworks the user message bubble in ChatRow to recover vertical space in the constrained chat panel.

Repeated "You said" / "Zoo said" headers occupy a separate line plus surrounding spacing for each message, reducing how much actual content fits on screen. Removing these redundant header rows makes more of the conversation visible at once and reduces the need to scroll, while alignment, bubble width, and background color distinguish user and assistant turns.

user_feedback: rendered as a right-aligned w-fit bubble (max-w-[70%], ml-auto, items-end) with no header label; edit/delete buttons move below the bubble; uses soft list-hoverBackground/text-foreground when not editing and keeps editor-background/foreground while editing.
user_feedback_diff: diff bubble aligned to the right (max-w-[70%] ml-auto).
text: drops the "You said" / "Zoo said" header label and distinguishes turns by alignment, width, and background color; the markdown preview button is absolutely positioned in the top-right corner.
Removes now-unused User and MessageCircle icon imports.

Reviewers should note that turn identification now relies on visual alignment/background rather than an explicit role label.

Test Procedure

Unit tests: cd webview-ui && npx vitest run src/components/chat/__tests__/ChatRow.user-feedback-bubble.spec.tsx
Visual snapshot: run the visual-regression suite and confirm the committed chat-row-* snapshots match.
Manual: send a message and an edited message; confirm the right-aligned bubble, correct non-edit/edit background colors, and button placement below the bubble.

📝 Summary

Summary by CodeRabbit

Improvements
- User feedback messages and diffs are right-aligned and displayed in more compact bubbles, with clearer separation between message content and edit or delete controls.
- Edit and delete controls stay hidden while a message is being edited or streamed.
- Message text can be activated with Enter or Space to edit, except while streaming; selecting a mention opens it without triggering message editing.
- Assistant text messages no longer show a speech-bubble icon or “Roo said” header; the markdown preview button appears over message content when available.
- Expanded user-edit details remain available alongside the conversation, with clearer content and improved readability.

📝 Summary

Walkthrough

Chat rows distinguish user feedback through right-aligned, width-constrained styling and render assistant text without a role header. The markdown-preview button appears over assistant content. Tests cover rendering, controls, mention clicks, and visual states.

Changes

Chat row presentation

Layer / File(s)	Summary
Chat row rendering and behavior `webview-ui/src/components/chat/ChatRow.tsx`, `webview-ui/src/components/chat/Mention.tsx`, `webview-ui/src/components/chat/__tests__/ChatRow.user-feedback-bubble.spec.tsx`	User feedback is right-aligned and limited to 70% width. Message text supports keyboard activation for editing, while edit and delete controls are hidden during editing and streaming. Assistant text has no role header, and its markdown-preview button appears over the message content. Mention clicks stop propagation. Unit tests cover these behaviors.
Conversation fixture and visual coverage `webview-ui/src/components/chat/__tests__/ChatRow.visual.fixture.tsx`, `webview-ui/playwright/gallery/stories.tsx`, `webview-ui/src/components/chat/__tests__/ChatRow.visual.tsx`	A three-message conversation fixture is registered as a gallery story. Playwright tests apply dark and light themes, check visible content, and capture screenshots with user actions and the assistant preview hovered.

Explanation

Issue [#1994] requires each user and assistant turn to be distinguishable by alignment, width, and background without a visible role header. The user_feedback and user_feedback_diff cases add right alignment and a max-w-[70%] limit. The text case removes the visible header and repositions the preview button, but its rendered containers still use only group, pl-6, and relative/pr-10; they add no assistant-specific alignment, width, or background styling. The controls remain real keyboard-operable buttons, and streaming still disables editing. The focused tests do not verify the missing assistant layout styling.

Full details: Regression Evidence

Explanation

The new tests cover non-empty user feedback only. ChatRow.tsx now adds a focusable role="button" around Mention, while ClineMessage.text is optional and real producers emit user_feedback with an empty string plus images (for example presentAssistantMessage.ts:675 and AttemptCompletionTool.ts:244). The added test helper uses only text: "hello bubble" and contains no image or empty-text case. This leaves the changed image-only/unset branch without focused coverage, including the accessible name and edit/delete behavior of that state. The new dark/light Playwright snapshots cover the non-empty conversation layout, but not this affected branch.

Resolution

Add a focused ChatRowContent test for an image-only user_feedback message with text: "" (and optionally an omitted text). Assert that the image remains in the constrained bubble, the edit and delete controls remain labelled and operable, and the focusable edit target has an accessible name or is not exposed as an empty button. Adjust the implementation if needed. Add a component snapshot for the image-only state if its layout is part of the intended visible UI.

the preview button is present.
- Around line 1257-1260: Update the ChatRow click handler so clicking a mention
does not invoke handleEditClick or enter edit mode; prevent the mention click
from reaching this handler, or exclude mention targets here while preserving
normal message-click editing.
- Around line 1255-1257: In the message interaction JSX in ChatRow, replace the
clickable divs for the message text and edit/delete actions with buttons, giving
each an accessible name that describes its action. Keep the action buttons
visible on keyboard focus as well as hover, while preserving their existing

- Line 1209: Update ChatRow’s root wrappers, including the ChatRowContent
wrapper and the text and user_feedback branches, to provide a localized
accessible sender name derived from message.type. Keep the name available to
screen readers without restoring visible headers.

webview-ui/src/components/chat/ChatRow.tsx (4)

1209-1212: Duplicate: Add clearance for the absolutely positioned preview button.

The absolute top-0 right-0 z-10 button overlays the markdown content. The content wrapper adds no right padding. A long first line or heading can render under the button when the button is visible. Add right padding, or a similar reservation, to the content when the preview button renders.

1255-1264: Duplicate: Make the message text edit trigger keyboard-operable.

The div with onClick has no role, no tabIndex, and no key handler. Keyboard users cannot enter edit mode from the message text. Use a button element or add equivalent semantics.

1257-1262: Duplicate: Mention clicks also trigger edit mode.

Mention calls vscode.postMessage without stopping propagation. The click bubbles to this handler and calls handleEditClick(). A user who opens a mention also enters edit mode. Ignore clicks that originate inside a mention, or stop propagation in Mention.

1209-1224: Duplicate: Add an accessible sender name for unlabeled turns.

The visible role headers are removed. The text and user_feedback roots expose no sender to screen readers. The issue requires screen-reader accessibility. Add a localized accessible name based on the message role.

90-107: Duplicate: Assert action behavior, not only presence.

The test finds the edit and delete icons but never activates them. Click edit and assert edit mode. Click delete and assert mockPostMessage receives { type: "deleteMessage", value: 1 }.

- Replace the edit/delete div wrappers in the user feedback row with button type=button controls that carry translated accessible names, reveal on focus-visible, and keep their stopPropagation click behavior. - Make the message text bubble a focusable role=button so keyboard users can enter edit mode, with Enter/Space activation and an aria-disabled state while streaming. - Stop mention clicks from bubbling into the row's click-to-edit handler so opening a mention no longer enters edit mode. - Update the user-feedback spec to assert behavior (deleteMessage payload, edit mode, mention propagation) instead of only element presence.

The i18n keys exist in all locale files.

The inspected locale files define confirmation.editMessage and confirmation.deleteMessage in common.json, and queuedMessages.clickToEdit in chat.json for every locale. The missing-key concern is not supported.

… controls

- Add role=group + aria-label to text and user_feedback ChatRow roots so screen reader users can identify the sender after visible headers were removed - Add pr-10 right clearance to assistant text content so the absolute-positioned markdown preview button does not overlap long headings or lines - Remove aria-label from user feedback bubble (role=button) so the message text becomes the accessible name; title remains as a pointer-user edit hint - Update keyboard test selectors to find the message button by its text content instead of the removed aria-label Tests: chat 41 files / 471 tests passed, tsc exit 0, eslint exit 0.
