Update Agents
“Design rarely moves in straight lines. Update agents let architects correct, refine, and converge without losing the work they’ve already validated.”
- Amy Kim, Product Specialist

What’s New

The AI Stack now supports update agents, allowing you to refine an existing AI-generated design through follow-up prompts instead of rerunning the entire stack. You can freely adjust the program, dimensions, or storey distribution; Snaptrude now updates only what’s needed while preserving everything else.

This turns the AI Stack into an iterative, state-aware workflow.

Why This Matters

  • Iterate toward the right outcome without drifting on every rerun
  • Preserve completed steps and confirmed decisions
  • Apply both small tweaks and larger changes intentionally
  • Resume the stack seamlessly if a connection drops

Instead of restarting, you now build on top of the latest confirmed state.

How It Works

  • Follow-up prompts are routed to the appropriate update agent (program, dimensions, or storeys)
  • The system applies the smallest possible change to satisfy your request
  • Unaffected outputs remain untouched
  • After the update, the stack continues forward automatically to produce a clean result

You can prompt mid-flow or after the stack completes- updates always apply to the latest state.

Example Scenarios

Mid-stream refinement

“Reduce service area and merge storage into it.”

→ Only service areas update; the rest of the stack stays intact.

Late-stage adjustment

“Move amenities to the ground floor and spread residential across 8 storeys.”

→ The stack revises the final output without restarting.

This update makes the AI Stack conversational, resilient, and truly iterative, bringing it closer to how architects actually think and design.
