New in version
3.2.0
Choice
lets the LLM present a set of options as clickable buttons instead of asking the user to type a response. The selection flows back into the conversation as a message, giving the LLM clean structured input.

This registers a single tool:
Tool
Visibility
Purpose
choose
Model
Shows a card with clickable options, sends the selection back as a message
The LLM calls
choose
with a prompt and a list of options. The user sees a card with one button per option. Clicking one sends a message back into the conversation:
"Which deployment strategy?" — I selected: Blue-green
This is an advisory interaction, not an enforcement mechanism. The conversation isn’t blocked while the card is open — the user can keep typing, and the LLM could proceed without waiting. The tool description instructs the LLM to stop and wait for the “I selected:” response, but for hard enforcement, implement selection logic server-side.
​
Configuration
The constructor sets defaults; the LLM can override
title
per-call.

The LLM provides the options per-call:

​
How it works
Each option renders as a full-width button in a vertical stack. When the user clicks one:
SendMessage
pushes the selection into the conversation as a user message
SetState("decided", True)
replaces the buttons with “Response sent.”
The tool description instructs the LLM to stop and wait for the “I selected:” message before proceeding with whatever the user chose.
