Support an independent Ultracode toggle at any Claude effort level

[makeavish]

Please add a separate Ultracode on/off toggle, independent of Claude's effort setting, as shown in this post and demo.

T3 currently couples Ultracode to xhigh. The updated behavior should allow combinations like Low or Medium + Ultracode, preserving the selected effort when toggling it on or off. Ideally, include a keyboard shortcut like Tab where it doesn't conflict with existing controls.

+1 would be great

I'd like to have this too. I want to play around with ultra code but I'd much rather do so on high.

I put together a draft implementation of this in #20987, in case it helps move the discussion along.

For context: since Claude Code 2.1.284, Ultracode is its own toggle that "no longer forces xhigh effort and stays on at any effort level". The VS Code effort slider also replaced its Ultracode stop with a separate switch. T3 still offers Ultracode as a Reasoning choice that the manifest maps to xhigh. So Max + Ultracode isn't possible, and neither is a cheaper High or Medium + Ultracode for long workflows on usage-limited plans.

How the draft works

• The Reasoning picker lists only effort levels. Ultracode becomes a separate On/Off control, like Fast Mode. The trigger shows e.g. Max · Ultracode while it's on.
• The manifest is unchanged. Every installed release reads the remote manifest, and older releases only understand Ultracode as an effort choice. So the server lifts the manifest's ultracode effort choice into a boolean option when it builds the Claude catalog. Older releases keep working, and newer ones get the toggle.
• Chat and text generation send settings.ultracode: true with whatever effort is selected. Mid-session changes already sent the two as separate keys.

Open questions for maintainers

• Saved threads: in the draft, threads saved with effort: "ultracode" fall back to the default effort with Ultracode off. Should they instead migrate to xhigh + Ultracode on?
• Older Claude Code: before 2.1.284, ultracode: true meant xhigh plus workflows. Should the toggle require 2.1.284 or later?
• Resume: Claude Code treats the interactive toggle as session-only. Should T3 turn it back on when a thread resumes, as it does today?

The Tab shortcut from the original post isn't in the draft. That could be a small follow-up if the direction is approved.

Please include the mobile app too.

Confirmed on Claude Code 2.1.302 (change in 2.1.284: "Changed Ultracode into its own toggle in /effort ... it no longer forces xhigh effort and stays on at any effort level"). In the terminal I run dynamic workflows at High or Medium. In T3 the only way to get Ultracode is the Reasoning choice, which the model manifest maps to xhigh.

The mobile Reasoning sheet should get the same On/Off toggle, so desktop and mobile behave the same (related: #14408, #18867). Thanks for the draft in #20987.
