Ask User — Choice Gate Pattern

Contract

• Present 2-4 options (no more — decision paralysis kicks in past 4).
• Always include an escape hatch (Skip, Cancel, or "none of these").
• Stop the turn immediately after presenting choices. No follow-up tool calls, no preemptive action, no default-and-proceed.
• The user's response triggers the next turn. Acknowledge briefly, then branch.
• One question per message — never stack multiple choice gates.
• Self-explanatory option labels: action verb plus brief qualifier, not "Option 1".

What This Is

A formalized pattern for presenting users with 2-4 options and stopping execution until they respond. This is the canonical way to gate on user input in any GBrain-powered agent.
