Debug static, hiss, or noise on embedded I2S audio (ESP32 + MAX98357A / PCM DACs), especially streamed PCM. Measure the signal at each pipeline stage instead of guessing at the amp. Use when audio plays but sounds wrong.

Generate a printable Typst build guide (source + PDF) for an ESP32/MCU project by analyzing its docs, source, and schematic

Register a project in the monorepo — justfile mod, CI matrix, standard file inventory

Standardize credential handling for an ESP32 project (credentials.h.example, .gitignore, pre-commit protection)

Set up ESP-IDF development environment, create new projects, and verify configuration

Generate a CLAUDE.md for a project with build commands, hardware constraints, architecture, and development tasks

Audit project completeness against the monorepo standard checklist (docs, config, registration)

Generate a standardized README.md for an ESP32 project by analyzing source code, justfile, and hardware configuration

Audit sdkconfig.defaults by inferring needed settings from source code analysis

Run robocar physics simulation environment

Apply or audit the canonical ESP-IDF WiFi STA configuration for a monorepo project

Generate a standardized WIRING.md for an ESP32 project by analyzing source code pin assignments

Debug and synchronize communication between the robocar main controller (Heltec WiFi LoRa 32) and camera module (ESP32-CAM)

Embedded systems development best practices for ESP32, FreeRTOS, and ESP-IDF. Use when writing firmware code, reviewing implementations, or learning about embedded patterns.

Debug ESP32 firmware issues including compilation errors, runtime panics, memory issues, and communication failures

Safely execute build, flash, and monitor operations for ESP32/MCU projects. Prevents dangerous operations and validates commands before execution.

Build an ESP32 project (containerized)

Full development cycle - build, flash, and monitor

Flash firmware to an ESP32 device

Run linting and formatting checks on codebase

Start serial monitor for MCU device

Research and report on new microcontroller board releases from ESP32, STM32, and other manufacturers

Review embedded C/C++ code changes for best practices
