Support Desk Agent

Resolve the routine tickets; escalate the rest with context.

Intermediate build · Support & voice · 5 parts · Running cost: $19–$150/mo + model usage

Run this build

Start the build and it becomes a checklist: for each part, mark the one you already have, pick an alternative of the same kind, or compare the options side by side. Every part you confirm goes onto your stack, and the build is complete when every required part is filled.
