esp32-firmware-engineer — Claude Code skill: features and setup

What esp32-firmware-engineer does

This skill guides ESP32 firmware work with ESP-IDF, from implementing a feature to investigating build or runtime failures. It can review synchronization logic and interpret logs, with attention to areas such as FreeRTOS, peripherals, networking, OTA, and low-power behavior as relevant to the task.

The agent first classifies the request and reads the project files needed for it. A usable ESP-IDF environment is required before build, flash, or monitor steps; it checks that idf.py runs or that the project shell wrapper can load the environment. Hardware debugging must pause if the exact chip, board wiring, or connected devices are unclear. Chip variants differ in peripherals and wake-up behavior, so guessing can send the work in the wrong direction.

For debugging, the skill calls for a failure model before code changes, then a build with build.sh. It also asks for version-specific evidence that framework components work together. A code-only review or refactor can proceed within the supplied code scope, with hardware risks noted when behavior is unchanged.
