#!/usr/bin/env bash
# examples/agent_demo/run_demo.sh — one-command agent-native demo.
#
# Starts the JustAPI agent demo, exercises all three differentiators
# (native MCP tools, durable sessions, Rust-validated streaming), shows the
# output, then stops the server. No manual steps.
#
# Usage:
# bash examples/agent_demo/run_demo.sh [port]
#
# Prereqs: the justapi package must be importable (e.g. a venv with
# `pip install justapi` or the repo's `.venv`).
