#xiaozhi

Advanced tutorial: add claude_cli, codex_cli and fallback LLM providers to xiaozhi-esp32-server, calling the locally logged-in official CLIs, with all tokens handled by the CLI itself. Tool calls use a <tool_call> text protocol and are not spoken aloud. If Claude errors, it automatically switches to Codex, and the failing provider cools down for 300 seconds. Includes full code, configuration, testing methods, and measured latency.
