Summary

The live-agent count badge on the right-panel toggle tells you something is working, but when the panel is already open on another surface (e.g. a Browser tab) nothing inside the panel says what the count refers to. There is no way to discover that the badge means "agents" short of hovering the toggle.

  • The Agents tab in the panel tab bar now carries the same count pill.
  • The Agents item in the tab bar's "+" add-surface menu carries the pill too, so the badge is traceable even when no Agents tab exists.
  • Both suppress while the Agents surface is active, matching the toggle's own rule (the roster is already on screen).
  • The pill uses the shared Badge primitive with compact count sizing and solid info color (also used by the empty-state card), and the tab, menu item, and card get an ", N agent(s) working" accessible label.

Verification

Merged upstream main at 7445aa733ada33e45289e5aa5055f79142556513 (20 September 2026).

  • vp test run apps/web/src/components/RightPanelTabs.test.tsx --maxWorkers 1: 20 passed.
  • vp exec tsc --noEmit -p apps/web/tsconfig.json: passed.
  • Targeted formatting, lint, and git diff --check: passed (existing warnings/suggestions may remain).

The UI consistency finding is addressed by reusing ui/badge with opt-in count size and infoSolid variant; existing Badge defaults are unchanged. The follow-up passed 20 tab tests, targeted lint/format, and web typecheck. A separate bounded SWE-2 Max review attempt for this follow-up also timed out (status 124).

UI evidence is incomplete: the three manual scenarios below still need a real-client pass and before/after captures. Existing tab tests do not verify the new badges visually.

Independent review was attempted before the final upstream sync, directly with devin -p --model swe-2-max using a frozen diff and repository standards. The noninteractive tool-based attempt returned without reviewing; bounded no-tool attempts timed out (status 124) without a verdict. No new independent approval is claimed.

Test plan

  • Open a thread with a running subagent and a non-Agents right-panel surface: the Agents tab shows the count.
  • With no Agents surface open, the "+" menu's Agents item shows the count.
  • With the Agents surface active, the tab/menu badges and the toggle badge are all hidden.

Original implementation: swe-2-high via Devin (Cursor harness). The prior description records a Claude Opus 5 review of that earlier revision; this is not approval of the current head.

Current upstream integration and focused verification: GPT-6 Astra in the Codex harness (T3 Code).

Summary by CodeRabbit

  • New Features
    • Added agent-count badges to empty-state cards, inactive Agents tabs, and add-surface menus.
    • Added accessible labels that describe agent counts and identify available and unavailable surface options.
    • Non-agent actions display a zero count, and agent counts are hidden while the Agents surface is active.
    • Count badges now use consistent sizing and styling across these interface areas.

Latest review-fix verification (e7c25ebc54): 21 RightPanelTabs tests passed; apps/web typecheck and targeted lint passed. The new badge color measures 5.256:1 contrast against white. Direct SWE-2 Max read-only review exited 0 with no confirmed blocking findings. Earlier verification and media describe prior revisions; no new browser verification was performed.

Approvability

Verdict: Approved at e7c25eb

Macroscope's review found this PR approvable — This is a focused right-panel UI fix that makes the existing agent count traceable through tabs, menus, and accessible labels. Changes are localized, opt-in styling additions preserve existing defaults, and focused tests cover the new labeling logic.

📝 Walkthrough

Walkthrough

The right panel now uses reusable agent count badges and accessible labels on agent-related controls. It suppresses agent counts when the Agents surface is active.

Changes

Agent count UI

Layer / File(s) Summary
Count labels and empty state
apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/ui/badge.tsx
The shared Badge supports count sizing and the infoSolid variant. The empty state uses a reusable count pill and accessible labels on available and unavailable actions.
Active-surface counts and tab/menu integration
apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/RightPanelTabs.test.tsx
Counts are suppressed on the active Agents surface. Inactive Agents tabs and the Agents add-surface item can display counts. Non-agent add-surface actions receive zero counts. Tests check empty-state labels at positive and zero counts.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Suggested reviewers: chrisdeeming

Merge Risk: 🔵 Low · up to b1b0c

When Agents is unavailable, screen-reader users still cannot hear how many agents are working. This is a bounded accessibility issue; expose the count through a nameable element before or alongside merging.

Expose the agent count on the disabled empty-state action.

When agentsAvailable is false and liveAgentCount > 0, the Agents row still renders AgentCountPill, but the pill is aria-hidden. The disabled row does not receive the new accessible label, so assistive technology announces Agents without the number of working agents. Expose the count in this branch too, for example with visually hidden text.

Re CodeRabbit's outside-diff finding "Expose the agent count on the disabled empty-state action" (RightPanelTabs.tsx:545-549): fixed at b1b0c1bd58. The disabled Agents row rendered AgentCountPill but the pill is aria-hidden, so assistive tech announced "Agents" with no indication of the working-agent count. Added the same aria-label the enabled row already uses (${action.label}, ${agentsWorkingLabel(action.badgeCount)}) to the disabled row, with tests in RightPanelTabs.test.tsx covering both the labeled and zero-count (no label) cases.

The live-agent count on the right-panel toggle said something was
happening but, with another surface already open, nothing inside the
panel identified what. The count now also appears on the Agents tab and
on the Agents item in the add-surface menu, matching the existing
empty-state card and toggle suppression rules.

Rebased onto current main (66129c6, was 14 commits ahead) at 6528df3. One real conflict in RightPanelTabs.tsx: main's theme-token migration (#13397, rounded-[var(--control-radius)] -> rounded-(--control-radius)) touched the same lines as this PR's AgentCountPill/aria-label work. Resolved by keeping this PR's AgentCountPill + aria-label changes and adopting main's newer token syntax. Typecheck and the focused RightPanelTabs.test.tsx suite (22 tests) pass.

The disabled-Agents aria-label test rendered the whole RightPanelTabs
component to static markup and grepped the HTML string for an
aria-label attribute, which AGENTS.md rules out ("do not render
components to static markup to assert props or attributes").

The label itself is built by the existing pure agentsWorkingLabel
helper, so export it and test it directly instead of adding a second
render harness. Keeps the accessibility fix from 6528df3, drops the
static-markup assertions and the now-unused renderEmptyState helper.
