Esp32 Firmware Engineer

This one knows ESP-IDF inside and out. It walks you through FreeRTOS task design, peripheral drivers, Wi-Fi and BLE stacks, OTA partition layouts, and low-power sleep modes with the kind of detail you'd expect from someone who's debugged Guru Meditation panics at 2am. It won't let you move forward until you've specified the exact ESP32 variant, board wiring, and IDF version because those details actually matter for concurrency, memory layout, and peripheral availability. The skill includes triage checklists for crashes, build failures, and hardware bring-up, and it'll push you to add a service console if the USB port is free. Good for both greenfield firmware and hunting down race conditions in production code.
