fix: show computer-use action titles and align app icons

[Yash-Singh1]

Problem

Codex JavaScript and computer-use calls can show Node_repl.js or Js with a wrench instead of the supplied action title. Failed Sky calls often have no result metadata, so they lose their computer-use identity. Native app icons also sit below the label at approximately 91% desktop zoom.

Change

Use the supplied action title for js, node_repl.js, and cua_repl.js, including retained thread records. Infer Sky computer-use calls when result metadata is unavailable, while preserving explicit browser/computer metadata. Reuse the existing window-and-pointer BrowserAppIcon when a native app icon is unavailable, with the same SVG drawing on mobile, and a code icon for ordinary JavaScript calls. Avoid repeating the same source name in grouped summaries.

Align work-log icons with the first line's font cap height and baseline. Native app icons remain 20×20. Highlight expanded REPL code with the existing TypeScript grammar and cached highlighters on web/desktop and mobile.

Scope and approval

Requested by the maintainer in this development session. These changes address the reported computer-use activity presentation across the Codex adapter, retained records, and web/mobile clients. Desktop uses the web UI; no wire-contract or connection-mode changes are required.

Verification

• 527 focused tests passed across Codex projection, shared client presentation/grouping, web timeline labels, and mobile activity labels/icons. Shared tool-activity tests also passed.
• Scoped shared, client-runtime, web, mobile, and server typechecks passed. Targeted lint, formatting, server bundle build, and git diff --check passed.
• Verified native Electron at 100% and approximately 91% zoom, including wrapped labels and unchanged 20×20 app icons.
• Replayed copies of the reported Js records against isolated development state. The HTTP call shows its supplied title and code icon; the failed Sky call shows its supplied title and cursor. Expanded code retains its exact text with syntax colors in the Browser panel. No recorded tools were executed.
• Mobile presentation has focused test and typecheck coverage; native mobile rendering was not manually verified.

App icon alignment before and after at approximately 91% desktop zoom. The final fallback icon is shown in the retained-record screenshot below:

Approvability

Verdict: Approved at 955ce17

Macroscope's review found this PR approvable — This PR is a focused work-log presentation fix: it recovers action titles, distinguishes computer-use from ordinary JavaScript calls, aligns icons, and highlights existing code inputs across web and mobile. It changes display metadata and rendering only, preserves existing optional contracts, and includes targeted coverage without altering product defaults or execution workflows.

📝 Walkthrough

Walkthrough

The change recognizes JavaScript REPL calls across shared, server, client-runtime, web, and mobile code. It resolves titles and computer-use metadata, updates activity labels and icons, highlights REPL code arguments, and deduplicates repeated work-log source names.

Changes

JavaScript REPL Activity Presentation

Layer / File(s)	Summary
REPL recognition and title resolution packages/shared/src/toolActivity.ts, packages/shared/src/toolActivity.test.ts	Shared helpers recognize js, cua_repl.js, and node_repl.js. They resolve titles from input or retained values and infer the computer surface from tool names or code.
Activity projection and source handling apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts, packages/client-runtime/src/work-log/toolPresentation.ts, packages/client-runtime/src/work-log/toolPresentation.test.ts, packages/client-runtime/src/work-log/presentation.ts, packages/client-runtime/src/work-log/presentation.test.ts, apps/mobile/src/lib/threadActivity.ts, apps/mobile/src/lib/threadActivity.test.ts	The server adapter and client runtime resolve titles, surfaces, and sources for dynamic-tool calls. Mobile activity summaries use retained titles and code icons. Grouped source names are deduplicated while preserving first-occurrence order.
Web and mobile activity rendering apps/mobile/src/components/BrowserAppIcon.tsx, apps/mobile/src/features/threads/thread-work-log.tsx, apps/web/src/components/Icons.tsx, apps/web/src/components/chat/MessagesTimeline.logic.ts, apps/web/src/components/chat/MessagesTimeline.logic.test.ts, apps/web/src/components/chat/MessagesTimeline.tsx, apps/web/src/components/chat/V2ItemInspector.tsx, apps/web/src/components/chat/WorkLog.tsx	Activity views use computer and code icons and resolved tool titles. Expanded JavaScript REPL code arguments receive TypeScript highlighting. The web work-log row alignment changes, and the previous computer-use icon export is removed.
