A designer's feedback on the app was blunt: "the fonts, the border radius, the icons, the font hierarchy." #24776 fixed the base tokens, but a design council still scored it about 7/10, behind the Claude Code and Codex desktop apps. The sidebar was noisy, the composer controls did not match, and the details panel and settings had small inconsistencies.

This PR includes #24776 and the follow-up work. Each round was reviewed from fresh screenshots until the council scored T3 above both reference apps.

From #24776: Inter on Windows and Linux, a 4/6/8/12/16 radius scale, 1.75 icon strokes, a three-level settings hierarchy, and higher contrast.

Follow-up:

  • Sidebar:
    • The title leads each row. Read titles sit at 75% and brighten on hover; open and unread titles are full white.
    • Provider logos and inactive project favicons are gray. Color returns on the active row, on hover, and on focus.
    • PR numbers are neutral. Only the state icon keeps its color.
    • Project, branch, and time share one muted color.
    • The time label and Snooze/Settle swap instantly on hover, with no overlap.
    • Branch names cut at a word: "t3/clone-re…machine", not "…er-machine".
  • Composer:
    • The vertical separators are gone.
    • "Compact" is a ghost control like its neighbors.
    • Every composer uses one placeholder: "Ask anything. @ files, $ skills, / commands".
    • The checkout strip no longer looks disabled.
  • Details panel:
    • Each row has one leading icon.
    • Split-button hairlines show only on hover.
    • The check count reads "33/34 checks".
    • The lineage row matches the other rows.
    • The editor app icon is gray at rest.
    • A fresh draft hides the empty Push and "Changes +0 −0" rows.
  • Settings:
    • The inheritance marker is hidden for values set on this screen.
    • Labels are clearer: "Selected automatically", "Resume after usage limits", and "Snooze until limits reset". The labels also changed on mobile, in settings search, and in the user docs.
  • Color: chat body text is at 90%. In light mode, status labels and diff counts use darker tokens.

Council review

Rounds: 5

Delegate Round 1 (#24776) Round 2 Round 3 Round 4 Round 5
Claude Opus 5.5 7.1/10 not run not run 8.7/10 9.0/10
Muse Wonder Full 6.9/10 not run not run not run 7.9/10
Codex GPT-6.1 Sol 7.4/10 8.1/10 8.9/10 9.0/10 9.0/10

The council scored the reference apps with the same categories. Latest overall scores:

Delegate T3 (this PR) Claude Code Codex
Claude Opus 5.5 9.0 8.3 8.4
Muse Wonder Full 7.9 8.1 7.6
Codex GPT-6.1 Sol 9.0 8.3 8.5

Sol and Opus place T3 above both apps in every category. Muse is still short. Its round 5 asks were partly applied after that round:

  • Applied: the gray editor icon, the neutral PR number, the quiet empty draft, and the quieter settings marker.
  • Declined to hold scope: hiding sidebar agent logos, monochrome switches, and a gray model logo in the composer. Opus asked to keep that logo's brand color.

The current build has not been re-scored by Muse yet.

Made with Claude Opus 5.5 in Claude Code, running in T3 Code.

After a draft action completes with a clean, synchronized status, this condition hides the action group even while visibleInlineSuccess is set, so panel users see no completion confirmation. Keep the group visible until the inline success expires.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR is a broad, user-facing UI redesign that changes product defaults such as the composer placeholder, font stack, and global visual tokens. Unresolved findings also identify cases where Git actions or completion feedback disappear, along with touch and truncation usability issues.

Needs human approval because:

Merge Risk: Low · up to 3a6fd

Inheritance markers remain hard to discover on touch devices, some truncated labels split words, and a completed Git action can hide its success message. These bounded UI issues warrant owner awareness or follow-up.

Explanation

The description clearly explains the UI problems, lists the changes, and includes before-and-after screenshots. It does not provide the required Scope and approval section or a focused Verification section with checks performed and observed results. It also does not link a triaged issue or explicit maintainer approval for this broad UI change.

Resolution

Add explicit Problem, Change, Scope and approval, and Verification sections. In Scope and approval, link the triaged issue or maintainer approval comment, or explain why the change qualifies for an exception. In Verification, list the focused tests or manual checks, their observed results, and any checks not performed. Keep the existing before-and-after screenshots as UI evidence.

Keep the Git action result visible for a clean draft.

When a panel action succeeds and the refreshed Git status has zero insertions and deletions, quietEmptyDraft can become true while visibleInlineSuccess is still active. Line 1695 then hides the action group that displays the success result. Exclude visibleInlineSuccess from this condition so users can see the result before the empty-draft rows disappear.

Keep inheritance markers visible on touch devices.

When a device has no hover, this rule hides the “Built-in default” and “Set on the environment” markers. focus-visible does not reliably reveal them after a touch. Users cannot discover the marker or its details without tapping an invisible target. Keep these markers visible when (hover: none) applies.

Based on learnings, flag hover-dependent affordances that lack a usable touch path or a visible equivalent.

Include spaces in automatic word-boundary matching.

For project/ship the mobile update, the automatic tail is ile update because WORD_BREAK ignores spaces. Include whitespace so the tail can start at update. This also affects path labels with spaces.
