feat: claude effort controls, ultrathink UI, and adapter robustness by JustYannicc · Pull Request #1146 · pingdotgg/t3code

JustYannicc · 2026-03-16T19:53:12Z

What Changed

Claude Effort Controls & Ultrathink

Added ClaudeCodeEffort type with levels: low, medium, high, max, ultrathink
getEffectiveClaudeCodeEffort() maps effort levels to Claude SDK values
applyClaudePromptEffortPrefix() prepends "Ultrathink:" prefix to prompts
Generalized CodexTraitsPicker into a provider-aware traits picker with Claude effort labels
Ultrathink composer chrome: animated rainbow border, chroma pill badge, model picker glow effect

Adapter Robustness (Background Agents & Subagents)

Synthetic turn auto-start: Assistant messages arriving without an active turn (background agent/subagent responses between user prompts) now auto-start a synthetic turn so the response is visible in the UI
Stale turn cleanup: Auto-close orphaned synthetic turns in sendTurn to prevent session deadlock
Fragment leak prevention: Clear inFlightTools map in completeTurn to prevent stale JSON fragments from corrupting subsequent turns

Subagent Progress Surfacing

Claude task.progress events surface as activities with summary and lastToolName
collab_agent_tool_call classification for Agent/Task tools with "Subagent task" labels
Tests for tool classification and progress forwarding

Provider Health

Refreshed health check status probes with Fiber-based concurrent execution

Why

Background agent results, subagent responses, and tool call details were silently dropped because the adapter's turn state machine only handled user-initiated turns. When a background agent finished work and the lead generated a response, that response was invisible in the UI.

The effort controls bring feature parity with the Codex reasoning effort UI, adapted for Claude's effort model including the ultrathink mode.

UI Changes

Ultrathink mode shows an animated rainbow border around the composer and a chroma-animated "Ultrathink" pill badge
Effort dropdown shows Claude-specific labels (Low / Medium / High / Max / Ultrathink)
Provider model picker shows chroma animation when ultrathink is active

Checklist

This PR is small and focused
I explained what changed and why
I included before/after screenshots for any UI changes
Type checks clean across web, server, and contracts
All 35 existing tests pass

Note

Add Claude effort controls and ultrathink UI to the chat composer

Adds ClaudeCodeEffort options (low, medium, high, max, ultrathink) to contracts and shared model utilities, with ultrathink mapping to max at runtime and prefixing outgoing prompts with 'Ultrathink:\n'.
The chat composer resolves effort per provider, dispatches modelOptions.claudeAgent.effort in turn payloads, and shows an animated 'Ultrathink' pill and rainbow frame when ultrathink is active.
ClaudeAdapter forwards effective effort into Claude SDK query options and auto-closes a stale active turn instead of returning a validation error when sendTurn is called.
ProviderCommandReactor restarts the Claude session when modelOptions change between turns, and carries cached model options forward on runtime-mode changes.
ProviderTraitsPicker replaces CodexTraitsPicker with a provider-agnostic picker that shows Fast Mode only for Codex and uses provider-specific effort labels.
Risk: default Claude effort changes from null to 'high'; existing sessions without a persisted effort will now send effort: 'high' to the Claude API.

had to do some sweeping changes to align with anthropic branding guidelines. can you resolve the conflicts?

JustYannicc · 2026-03-16T22:54:33Z

yes working on it

JustYannicc · 2026-03-16T23:10:36Z

@juliusmarminge done. you should be able to merge it no problem now.

apps/web/src/components/Icons.tsx

  <svg {...props} preserveAspectRatio="xMidYMid" viewBox="0 0 256 257">
    <path
-      fill="#D97757"
+      fill="currentColor"


the Claude icon needs to inherit Tailwind text color from the caller. Icons.tsx (line 146) so the styling in ProviderModelPicker.tsx (line 120) actually works, including the normal Claude orange and the ultrathink-chroma state. With a hardcoded fill, those classes were ignored.

apps/web/src/components/chat/CodexTraitsPicker.tsx

  MenuTrigger,
 } from "../ui/menu";

-export const CodexTraitsPicker = memo(function CodexTraitsPicker(props: {


hmm not sure it's worth compacting these as one just yet... we don't really know what the future will look like so keeping them separate for now is the best. iirc i separated them when i had all codex/claude/cursor working because they had differernt enough logic to justify separate components instead of single component with switch statements internalyl

the reason for the refactor is that ChatView only renders one traits-picker slot, and the current UI shape is still the same for both providers: one menu, one effort selector, plus Codex-only fast mode in the same surface. You can point at ChatView.tsx (line 3630) and CodexTraitsPicker.tsx (line 37).

But if you want I can change the implementation to be less of an abstraction

packages/contracts/src/providerRuntime.ts

 const TaskProgressPayload = Schema.Struct({
  taskId: RuntimeTaskId,
  description: TrimmedNonEmptyStringSchema,
+  summary: Schema.optional(TrimmedNonEmptyStringSchema),


what does this cover that "description" doesn't? is it something claude specific? not opposed to keeping mostly curious

description is the provider’s raw task label, while summary is an optional more user-facing progress line when the provider gives both. Claude does give both on task_progress; see ClaudeAdapter.ts (line 1698). The ingestion layer then prefers summary for the activity detail and falls back to description; see ProviderRuntimeIngestion.ts (line 363). it is an optional field that preserves richer provider data without overloading description.

- Auto-start synthetic turns for assistant messages arriving without an active turnState (fixes invisible background agent/subagent responses that arrive between user-initiated turns) - Auto-close stale synthetic turns in sendTurn to prevent session deadlock when a background response left an orphaned turn open - Clear inFlightTools between turns in completeTurn to prevent stale JSON fragments from corrupting the next turn's tool inputs - Fix missing Fiber import in ProviderHealth Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The clear() was placed before the loop that emits item.completed events for remaining in-flight tools, causing the loop to never execute. Move it after the loop so tools get properly finalized before cleanup. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Updates all remaining references from "claudeCode" to "claudeAgent" to match the Anthropic branding guidelines applied upstream. Includes provider kind literals, object property keys, test payloads, and component comparisons across server, web, and shared packages. Also fixes synthetic turn state to match upstream's refactored ClaudeTurnState interface (assistantTextBlocks map instead of the old assistantItemId/messageCompleted/emittedTextDelta fields). Also fixes inFlightTools.clear() placement: moved after the loop that emits item.completed events for remaining in-flight tools, so tools are properly finalized before cleanup.
