Problem

Mobile agent rows omit effort and speed shown on desktop.

Change

Show saved effort beside the model and use the desktop bolt icons for fast and ultrafast. Keep one validated provider identity and text that truncates at the end.

Scope and approval

Focused display fix for existing agent rows under the small bug-fix exception. The scope stays within mobile metadata.

Verification

vp run check:changed and all 16 focused tests passed. The native iOS capture uses isolated sample data and verifies bolt placement and the spoken Fast mode label. Android and provider execution were not tested.

Before	After

Built with GPT-6.1-Sol in the Codex harness.

Takeover

Replaces #24629, with thanks to @Bil0000 for the original implementation and mobile captures above.
Rebuilt from main as one focused change, sharing the desktop speed formatter and existing effort formatter instead of retaining the original resolver and test suite.
Shows catalog effort labels and Fast/Ultrafast bolt icons. Missing or mismatched provider/model metadata hides traits; saved agent settings win, with an app-owned child fallback only when no saved selection exists.
The original description and captures above are retained for attribution; the final takeover verification is below.

Evidence

• Final proof audit and unit-test transcript
• Actual synthetic row models for all six providers
• Reproduction harness

Mobile UI (no Android tooling on fs-16) is unverified. The evidence uses synthetic inputs and prints presentation models; it is not a native UI capture. Web/desktop formatter reuse was checked with focused tests; no browser was used.

Verification log

• Main initially lacked the mobile effort/speed labels.
• Rewrote the original 16-case suite to 10 targeted cases, then added one absent-variant regression: 11 final tests.
• Initial main: 10 expected failures; absent OpenCode variant: 1 failure / 10 passes before the guard; final: 11 passes.
• Revert checks caught removed provider/model guards, child fallback, speed, and readable effort formatting.
• Three independent Codex/Claude review rounds; fixed long-label truncation, accessible speed grouping, and the proof-audit absent-variant finding. Both final reviews found no remaining blockers.
• Merged main with a merge commit, then ran focused tests and vp run check:changed: format, lint, knip, seven-package typecheck and changed-file tests all pass.
• Final head: 006a29e1bf.
• No live T3 userdata was accessed. No native device or browser verification was performed.

Implemented with Claude Opus 5.5 through the Claude Agent harness; reviewed and proof-audited with GPT-6.1-Sol through Codex and Claude Opus 5.5.

Walkthrough

The change adds shared speed-trait resolution for model selections and uses it in web tooltips and mobile subagent rows. Mobile trait resolution checks provider and model matches, with child-thread selection fallback for app-owned subagents.

Changes: Subagent model traits

Layer / File(s)	Summary
Shared speed-trait resolution packages/client-runtime/src/modelTraits.ts, apps/web/src/components/chat/SubagentTooltipContent.tsx, apps/web/src/components/chat/TraitsSpeed.tsx	The runtime resolves speed icons from option descriptors and saved selections. The web tooltip uses the shared resolver in place of local option handling, and the former getTraitsSpeedDisplay helper is removed.
Mobile subagent trait resolution apps/mobile/src/features/threads/threadAgentsPresentation.ts, apps/mobile/src/features/threads/threadAgentsPresentation.test.ts, apps/mobile/src/features/threads/thread-workflow-opening.tsx	The resolver validates provider, selection, instance, and model matches before returning effort and speed traits. Tests cover matching selections, app-owned child-thread fallback, and missing or mismatched data. Workflow members receive the provider_native origin.
Mobile subagent trait display apps/mobile/src/features/threads/SubagentRow.tsx	The subagent row displays available effort and speed traits with themed icons and a combined accessibility label.

Change: Bug fix

Suggested reviewers: bil0000, bmdavis419

Merge Risk: Minimal · up to 37b04

This change shows effort and speed on mobile agent rows and shares speed-icon logic with the web tooltip. No concrete merge-blocking risk was found. One minor published display edge case may remain, and the native UI was not verified.

Full details: Title check

Explanation

The title "fix(mobile): show agent effort and speed" matches the main change in the changeset. The mobile SubagentRow now shows saved effort and a Fast/Ultrafast speed icon, supported by new helpers in threadAgentsPresentation.ts and modelTraits.ts. The title uses a conventional commit format, is one sentence, and names the primary change without noise.

Full details: Description check

Explanation

The description follows the template sections: Problem, Change, Scope, and Verification. It states the bug, the fix, the scope under the small bug-fix exception, and the test results. It also includes before/after screenshots, a takeover note, and an evidence list. Two gaps remain. The Scope section does not link a specific issue. The Verification section does not cover the final iOS UI behavior, and it states that mobile UI is unverified. The template does not require these items to be complete in every case, so the description is mostly complete.

Minor · Functional Correctness · Quick win

Continue scanning recognized speed descriptors.

A recognized Normal/default descriptor has a non-null display object with a null icon. The current early return therefore prevents a later Fast or Ultrafast descriptor from supplying its icon. This can make mobile agent rows and web tooltips disagree with the existing trigger display, which gives later recognized descriptors precedence.

Suggested fix

+  let speedIcon: "fast" | "ultrafast" | null = null;
   for (const descriptor of descriptors) {
@@
     const display = savedDescriptor && getTraitsSpeedDisplay(provider, savedDescriptor);
-    if (display) return display.speedIcon;
+    if (display) speedIcon = display.speedIcon;
   }
-  return null;
+  return speedIcon;
