feat(mobile): see which agent thread needs you from the Live Activity by ndycode · Pull Request #28233 · pingdotgg/t3code

ndycode · 2026-10-31T18:21:46Z

Problem

The Live Activity doesn't say which thread needs you. When one thread asks for approval just as another finishes, both rows look the same, the expanded Island just says "T3 1", and VoiceOver reads the minimal Island as an unlabeled image.

Change

The Live Activity now leads with the thread that needs you, in every presentation.

One mark per phase: › starting, ›_ working, ›? input, shield for approval, check for done, octagon for failed, clock for stale. Each one reads without color, so it works in monochrome and on Always-On.
Order: the thread that needs you comes first, then failures, then work in progress, then finished threads. Tapping opens that thread with the existing t3code://threads/… link.
VoiceOver reads a sentence, for example "Fix login redirect needs approval. 1 needs you, 1 done".
Counts come only from the payload. Only the rows the relay sent count as working, so a thread beyond the five rows is never called working. Stale threads aren't counted as working, "+N more" counts threads, and nothing shows progress or time remaining. An unknown phase falls back to the stale mark instead of crashing.
Motion: one 0.3 s swap of the mark when the phase changes, and nothing else.
Showcase: new scenes (agent-activity:handoff-*, phase-*) make this reproducible.

Scope and approval

Proposed in the Ideas discussion #28232. Maintainer approval is pending. It uses the existing payload, relay and deep links, and adds no new data.

#26261 also edits AgentActivity.tsx, so one of the two will need a rebase.

Verification

(cd apps/mobile && vp test run --project unit src/widgets src/features/showcase src/features/agent-awareness): 51 passed. Each new test fails when its behavior is removed.
vp run typecheck, vp lint and vp fmt --check pass.

iOS 27 Simulator, iPhone 17 Pro. The Island shots are frames from device recordings, because simulator screenshots leave out the Dynamic Island. The simulator can't be locked, so "Lock Screen" is the pulled-down cover sheet.

	Before	After
Compact
Expanded
Lock Screen
Needs input

Handoff: both threads working, then approval, then expand, then a tap opens "Fix login redirect". The showcase stages two scenes, so the app briefly comes to the front in between.

Videos: after · after, input · before

Not checked: the minimal Island (it needs a second app's Live Activity), long titles on the simulator, Reduce Motion and Always-On on the simulator, and a physical device.

+  const needsYouCount = activities.filter((row) => SIGNALS[row.phase].rank === 0).length;
+  // activeCount includes threads the relay already reports as stale; they are not working.
+  const staleCount = activities.filter((row) => row.phase === "stale").length;

🟠 High widgets/AgentActivity.tsx:183

workingCount reports undisplayed active threads as working even when they are waiting for approval, so the summary can claim agents are working when none are. activeCount includes threads omitted by the relay’s five-row activities limit; keep those threads separate from the working count or pass aggregate phase counts.

🤖 Copy this AI Prompt to have your agent fix this:

In file @apps/mobile/src/widgets/AgentActivity.tsx around line 183: `workingCount` reports undisplayed active threads as working even when they are waiting for approval, so the summary can claim agents are working when none are. `activeCount` includes threads omitted by the relay’s five-row `activities` limit; keep those threads separate from the working count or pass aggregate phase counts.

Fixed in ee6bd07: "working" now counts only the running or starting rows the relay sent. Threads past the five-row cap show only in "+N more", and VoiceOver reads them as "N more". New test: six approval threads with five rows read "5 need you", never "working".

Walkthrough

The mobile showcase now supports named agent-activity fixtures and retains the activity scene on thread routes. Live Activity staging handles cancellation and stale rows. The AgentActivity widget presents ranked activity across its layouts, with updated status, accessibility, and deep-link behavior.

Changes: Showcase Agent Activity

Layer / File(s)	Summary
Fixture definitions and activity construction `apps/mobile/src/features/showcase/showcaseAgentActivity.ts`, `scripts/mobile-showcase-environment.ts`	The activity builder supports named fixtures and reports active, failed, or completed status. The showcase environment adds two settled threads.
Native fixture requests and activity staging `apps/mobile/src/features/showcase/nativeShowcaseScene.ts`, `apps/mobile/src/features/showcase/ShowcaseCaptureCoordinator.tsx`, `apps/mobile/src/features/showcase/stageShowcaseAgentActivity.ts`, `apps/mobile/src/features/showcase/stageShowcaseAgentActivity.test.ts`	Native requests can select a fixture. The coordinator passes it to the builder and cancels replaced runs. Staging checks cancellation and sets a stale date when any row has the stale phase.
Agent-activity scene routing `apps/mobile/src/features/showcase/showcaseCaptureModel.ts`, `apps/mobile/src/features/showcase/showcaseCaptureModel.test.ts`	The agent-activity scene remains on screen for thread and review routes.
Ranked activity widget presentations `apps/mobile/src/widgets/AgentActivity.tsx`, `apps/mobile/src/widgets/AgentActivity.test.ts`	The widget presents a ranked hero thread and additional rows across its layouts. Tests cover phase marks, stale and working counts, deep links, hidden rows, and accessibility labels.

Suggested reviewers: juliusmarminge, maria-rcks, macroscopeapp

Merge Risk: Low · up to ee6bd

The change reworks Live Activity presentations and showcase staging. No functional defect was found in the reviewed code. The one open item is a test that polls with vi.waitFor instead of awaiting an explicit signal, which is a small cleanup. The change is mergeable with that follow-up.

Note

Written by gpt-6.1-sol on behalf of Maria

Verified in a real dev environment

no changed behavior could be exercised on this linux vm. result: unverifiable, not a runtime pass.

inspected the description, full nine-file diff, commit authors, discussion, reviews and checks for head 9d6d4260b16cc0fb70b81dccf81eff9c97e05de6. git.cafe reports 29 successful checks, zero pending and zero failing; these do not establish device behavior.

prerequisite transcript:

uname: Linux x86_64
command -v xcrun: no executable
command -v xcodebuild: no executable
device_list: Agent device access is turned off for this environment.

the production change renders an ios live activity through expo-widgets and swiftui. live activity registration is ios-only, and the non-ios implementation returns no activities and cannot start one. the remaining changes are native showcase support and tests. a web codex turn would not reach this changed rendering path.

Not verified

main reproduction and pr runtime verification were blocked before starting either dev server. no real provider turns, synthetic showcase data, screenshots or recordings were produced. no code was changed or pushed.

requires an ios device or simulator with the native client and a reachable development backend: create real codex gpt-6.1-sol threads, leave one awaiting approval or input while another completes, then compare main and this head. check compact/minimal/expanded island and lock screen presentations, priority and counts, and tap-through to the leading thread. neighboring working/completed/failed/stale states, hidden-thread counts, voiceover, monochrome/always-on rendering and phase transitions remain unverified. relay-driven updates also remain unverified.

Minor · Maintainability & Code Quality · Quick win

Replace the vi.waitFor polling with a deferred signal.

Line 54 uses vi.waitFor to poll until endCalls becomes 1. The testing rules allow vi.waitFor only for browser test assertions. This is a unit test. Unit tests must await a Deferred or another explicit signal instead of polling.

The mock already controls end. Make the first end call resolve a promise, and await that promise.

♻️ Proposed fix

let finishEnding = () => {}; const ending = new Promise<void>((resolve) => (finishEnding = resolve)); - let endCalls = 0; - native.activities = [{ end: () => (endCalls++ === 0 ? ending : Promise.resolve()) }]; + let endCalls = 0; + let markEndStarted = () => {}; + const endStarted = new Promise<void>((resolve) => (markEndStarted = resolve)); + native.activities = [ + { + end: () => { + if (endCalls++ > 0) return Promise.resolve(); + markEndStarted(); + return ending; + }, + }, + ]; let replaced = false; const first = stageShowcaseAgentActivity(fixture("store"), 0, () => replaced); - await vi.waitFor(() => expect(endCalls).toBe(1)); + await endStarted; replaced = true;

As per coding guidelines: "Never wait on sleeps or polling… Browser tests assert through expect.element or vi.waitFor" and "No yieldNow or sleep polling loops. Await the Deferred, take from the Queue, or drain the worker."

Committable suggestion

IMPORTANT
Review the replacement and indentation, then test before committing.
