Patter SDK Guide to Building a Restaurant Booking Phone Agent with Dynamic Variables, Guardrails, Latency Dashboards, and Eval Checks

Short summary

This guide walks through building a restaurant booking voice agent using the Patter SDK, covering dynamic caller variables, callable tools for availability and bookings, output guardrails, and latency/cost tracking via a dashboard. The agent is validated with a deterministic eval harness using scripted call flows before mapping the same logic to a real deployment with Twilio and OpenAI Realtime. It serves as a practical blueprint for production-grade AI voice agent development with built-in safety and observability.
