Agent Skills: rc-submarine-controller

Development skill for building a Raspberry Pi Pico-based RC submarine controller with ballast control, depth hold, pitch stabilization, and failsafe protection. Use when working on embedded C firmware for RP2040, implementing PID controllers, writing sensor drivers (pressure, IMU), PWM capture/output, dual-core safety-critical systems, or any task related to the RC submarine project. Also triggers for Power of 10 coding standards, Pico SDK usage, and underwater vehicle control systems.
