[Regression] Auto/Agent often routes to Composer without AskQuestion — popup Q&A broken (was working before)

Describe the Bug

When using Auto in Agent mode, the session frequently lands on Composer. In those sessions the built-in AskQuestion tool is not in the agent tool list, so the agent cannot show the native multi-choice popup UI and falls back to plain-text questions in chat.

Previously, Auto sessions often still had AskQuestion popups (likely when Auto routed to a third-party model). Now Auto commonly routes to Composer, and AskQuestion is missing — even though Auto+Composer and API quotas are still available. Quota remaining does not restore AskQuestion.

This matches the known issue that Composer/Auto do not properly expose AskQuestion in Agent mode:

The Composer model cannot use the AskQuestion tool

Ask: Please treat this as a regression / product gap for Auto users who rely on structured clarifying questions. Ideal fix: mount AskQuestion for Auto→Composer Agent sessions the same way third-party models get it (or document clearly that Auto cannot guarantee AskQuestion).

Steps to Reproduce

1. Open Agent chat, set model to Auto.
2. Ask the agent to use AskQuestion for a single-select clarifying question.
3. Observe: tool unavailable / text-only questions; model identity often Composer.
4. Switch model picker to Claude / GPT / Haiku (Agent) or use Plan mode → AskQuestion popup works.

Expected Behavior

Auto Agent sessions should still be able to call AskQuestion and show the native option UI when clarification is needed.

No - Cursor works, but with this issue

This isn’t actually a regression, and Composer 2.5 still has AskQuestion. The limitation you linked (Composer not using AskQuestion) was fixed back in April, so Composer 2.5 shows the structured picker normally in Agent mode now.

What you’re hitting is a different model. The structured AskQuestion picker is currently turned off for Grok 4.5, and Auto can route to it. When that happens, the model asks clarifying questions inline as plain text instead of showing the popup. This is intentional for now (not a quota issue, which is why remaining quota doesn’t bring it back), and it applies in every mode for Grok 4.5, so Plan mode alone won’t restore it while Grok is the model in use.

The reliable fix is what you already found: pick a specific model instead of Auto. Composer 2.5, Claude, or GPT in Agent mode all show the AskQuestion popup normally.

We do plan to bring AskQuestion back for Grok 4.5, but there’s no ETA to share yet. A few others are tracking it here: Grok 4.5 cannot use AskQuestion tool; falls back to inline questions (Composer 2.5 works)
