Hey! Thanks for contributing, is it true, that we can handle things like that https://github.com/orgs/agentclientprotocol/discussions/371 with this feature?

Just for some context, OpenCodes question tool schema:
https://github.com/anomalyco/opencode/pull/7268/changes#diff-2036e0c76252554ccff3dfc803b49917c90430275cadc8f9962ba528780c4e79
Claude codes question tool schema:

I guess these question tools as well as MCP elicitaiton are the most common use cases for this feature (+ perhaps some onboarding flows).
This is one of the biggest gaps in ACP currently I think, so +1 from me for this RFD :)

Hey @ignatov these type of spec should allow for that type of "question" form to happen. In fact, my existing ACP needs is all about such feature.

I am trying to write the spec AND figure out if I can make Zed GUI to implement it.

Overall, the intent is to allow structure input from the user such as Questionnaire, or buttons for specific auctions (at least that is my immediate need).
