error-message-explainer
Interprets Arduino/ESP32/RP2040 compiler errors in plain English for beginners. Use when user shares error messages, compilation failures, upload problems, or asks "what does this error mean". Covers common errors like undefined references, type mismatches, missing libraries, and board-specific issues.
code-review-facilitator
Automated code review for Arduino/ESP32/RP2040 projects focusing on best practices, memory safety, and common pitfalls. Use when user wants code feedback, says "review my code", needs help improving code quality, or before finalizing a project. Generates actionable checklists and specific improvement suggestions.
arduino-project-builder
Build complete, production-ready Arduino projects (environmental monitors, robot controllers, IoT devices, automation systems). Assembles multi-component systems combining sensors, actuators, communication protocols, state machines, data logging, and power management. Supports Arduino UNO, ESP32, and Raspberry Pi Pico with board-specific optimizations. Use this skill when users request complete Arduino applications, not just code snippets.
