Task

Generate or update a WIRING.md file for the project at $1 (relative path under packages/<domain>/).

Process

1. Read the project source code to discover pin assignments, components, and peripherals:

   • main/*.c and main/*.h — look for #define pin assignments, gpio_config(), i2c_config(), spi_bus_config(), LEDC, UART, ADC usage
   • main/CMakeLists.txt — REQUIRES list reveals components (mdns, driver, esp_wifi, led_strip, etc.)
   • sdkconfig.defaults — enabled features, stack sizes, Bluetooth mode
   • justfile — target chip, build variants
   • README.md / CLAUDE.md — existing hardware description
   • Kconfig.projbuild — user-configurable pin assignments

2. Identify the board from sdkconfig.defaults (CONFIG_IDF_TARGET), CLAUDE.md, or justfile. Note any board-specific constraints (e.g., ESP32-CAM PSRAM conflicts, TTGO LoRa pin reservations, ESP32-S3 USB PHY sharing).

3. Generate WIRING.md following the template below. Include ONLY sections relevant to the project — omit empty sections rather than adding placeholder text.
