Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR renders workspace images in expanded read entries on web and mobile. It is mergeable with owner awareness because the web path handling does not visibly enforce workspace-root containment before asset resolution, which could request an out-of-workspace image if upstream validation is insufficient.

UI consistency review found one keyboard-interaction regression and two smaller ownership/consistency issues in the changed web UI. Details inline.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces new workspace-image previews and lightbox interactions across the production web and mobile work-log paths, with new asset loading and feed-model plumbing. Its scope is beyond a minor isolated UI adjustment, so the cross-platform runtime behavior merits human review. You can add or adjust custom eligibility rules. Learn more. |
Agents reference screenshots they saved into the workspace by path (relative, absolute, or file://). Those bytes only exist on the environment host, so both clients rendered a broken or empty box. Web: a custom img renderer resolves workspace paths through the signed workspace-file asset endpoint; remote http(s)/data images keep their existing inline rendering. iOS: the t3-markdown-text module accepts a renderImage hook (provided via context) and ThreadFeed supplies a component that resolves paths against the workspace root, loads via useAssetUrl, and supports tap-to-expand into the existing full-screen viewer. Android: the nitro-markdown fallback path registers an image renderer backed by the same component.
- Surface asset-URL failures as 'Image unavailable' instead of an indefinite spinner (useAssetUrlState on mobile mirrors web's states). - Normalize file:///C:/... drive URIs (drop the URL parser's leading slash) and map file://host/share URIs to UNC paths. - Treat protocol-relative //cdn... image srcs as directly loadable on web and non-workspace on mobile.
…play Review bot follow-ups: the mobile markdown-image parser rewrote the historical file://localhost/... spelling into a UNC path, and the web workspace image's 'block' utility lost to the unlayered .chat-markdown img rule, so its display flipped when loading finished. Also announce the loading placeholder to assistive tech via role=status.
Expanding a 'Viewed (image)' or image-read tool call previously showed only the file path as text. Read-classified entries whose detail is a single workspace image path now render the image itself above the text detail, loaded through the same signed workspace-file asset URL the chat markdown images use. Web rows open the existing lightbox on click; mobile reuses ThreadMarkdownImage with its fullscreen viewer.
Review bot follow-ups: keydown on the preview button bubbled to the row's role=button handler, whose preventDefault cancelled the button's click activation — Enter/Space collapsed the row instead of opening the lightbox. Stop key events at the expanded-body wrapper like pointer events, give the button a focus-visible ring, and swap the hand-rolled loading placeholder for the shared Skeleton with role=status.

One finding on the new expanded-row image preview: the blanket onKeyDown={stopRowToggle} also swallows window-level keyboard shortcuts while the preview button is focused. Details inline.

Centralize the shared image-path classifier in packages/client-runtime.
The web and mobile implementations currently duplicate the supported-entry and path-validation rules. Keep one minimal classifier and import it from both clients so those rules cannot drift and classify the same read entries differently.

Fixed in 64d99e1. The image-entry classifier now lives in @t3tools/client-runtime/work-log-images and both web and mobile consume it; the shared package owns the focused classifier coverage.

One finding: the read-entry predicate is now duplicated between MessagesTimeline.logic.ts and the new shared workLogImages.ts. Everything else in the web changes looks consistent — the preview button follows the existing cursor-zoom-in image-target pattern in this file, the loading state now uses the shared Skeleton primitive, the asset URL is scoped to the row's threadRef.environmentId (with the control suppressed when threadRef is null), and the row keydown guard plus stopRowToggle keep Enter/Space activation on the image from toggling the row.

Stacked on #6433 — only the commits after the parent PR are new; it builds on the signed workspace-file asset URLs introduced there.
Problem
Expanding a "Viewed (image)" / image-read tool call in the timeline only showed the file path as text — the image the agent looked at was never visible (raised by maria on Discord as a follow-up to #6433).
Fix
Read-classified tool entries (
image_view,file-read, Cursor's "Read File") whose detail is a single workspace image path now render the image itself above the text detail when the row is expanded:ToolCallExpandedImageinMessagesTimelineloads the image through the signed workspace-file asset URL, only while the row is expanded (collapsed rows never fetch). Clicking opens the existing image lightbox. On load failure it renders nothing — the path stays visible in the text body.ThreadFeedActivityrows carry aviewedImagePath, and the expanded work-log detail reusesThreadMarkdownImage(loading/unavailable states, fullscreen viewer on tap) via a render prop fromThreadFeed.The image-path predicate reuses
isWorkspaceImagePreviewPathfrom@t3tools/shared, so the client only attempts extensions the asset route will actually serve. Unit tests cover the web predicate; the mobile activity fixture gained the new field.Web
