Support AskUserQuestion tool with multiple-choice options on mobile #635
Description
Feature Request
When Claude Code calls the AskUserQuestion tool, the mobile interface shows raw JSON and only yes/no buttons. The actual question text and multiple-choice options aren't rendered, and there's no way to select a specific option.
Current Behavior
- Claude calls
AskUserQuestionwith structured input:{ "questions": [{ "question": "Which approach should we use?", "options": [ { "label": "Option A", "description": "..." }, { "label": "Option B", "description": "..." } ] }] } - Happy routes it through the generic permission system (
--permission-prompt-tool stdio) - Mobile shows "Claude wants to Ask User Question" with raw JSON arguments
- User can only tap Approve/Deny
- On approve,
handlePermissionResponsereturns the original input unchanged — no selection is captured
Expected Behavior
- Mobile UI detects
AskUserQuestiontool calls and renders the question text and option buttons - User taps an option (or types a custom response)
- The selection is sent back and injected into the response to Claude
Technical Context
The limitation is in the permission response format — it only carries approved, reason, mode, and allowTools. There's no field to carry the user's selection back. The handlePermissionResponse method resolves with { behavior: "allow", updatedInput: pending.input } (original input, unchanged).
This would require changes in:
- Mobile app: Detect AskUserQuestion in agent state requests, render question/options UI
- Permission response schema: Add a field for user selection (e.g.
answerorselectedOptions) - CLI handler:
handlePermissionResponseto construct a proper response for Claude with the user's answers
Workaround
For now, Claude can use the <options> XML block in its text output (which Happy already renders as tappable buttons) instead of the AskUserQuestion tool when running through Happy.

Current behavior of it auto answering questions is making the tool unusable for my workflows. Planning mode is so useful in regular claude but unusable here.

What's the status on this?
I see that @bbaldino has implemented it. Will you make a pull request?
Miista commentedon Feb 28, 2026
@Balding does your implementation support multiple questions?
bbaldino commentedon Feb 28, 2026
Yeah. I had a couple other tweaks I did after that initial commit though. Also added the "Chat about this" option at the bottom.

I use android and did a preview build for myself. This meant hosting the relay server too
No they're not merged here
Miista commentedon Mar 1, 2026
@bbaldino shouldn't we get them merged here? :)

Pretty sure happy devs gave up on this project. There was another called Happier that is being worked on. But now that Anthropic is getting better mobile support I'm sure these tools will be obsolete soon.
Miista commentedon Mar 2, 2026
@nikhilsitaram we'll see. I actually came here because I found Anthropic's implementation lacking. That could change, though.
bbaldino commentedon Mar 2, 2026
Didn't know about happier, that's promising. But yeah I didn't find anthropic's built-in version to be very good either, so I started patching what I was running into here.

I'd love to try Happier but it's not released yet. Cc: @leeroybrun

@Miista @bbaldino @nikhilsitaram thank you for the interest! :) I updated the Happier readme yesterday with the instructions on how to use it. Please note that it's in alpha preview release stage, so not fully stable yet. I have a big update coming soon with a lot of new features and improvements, though.
