Safe Build Operations Skill

This skill enables safe execution of build system operations with appropriate safeguards.

When to Use

• Building firmware projects

• Flashing devices

• Monitoring serial output

• Cleaning build artifacts

• Running development workflows

Permitted Operations

Build Commands

make build-all make build-esp32 make robocar-build-all make robocar-build-main make robocar-build-cam make esp32-webserver-build make esp32-audio-build make llm-telegram-build

Flash Commands

make robocar-flash-main PORT=/dev/ttyUSB0 make robocar-flash-cam PORT=/dev/ttyUSB0 make esp32-webserver-flash PORT=/dev/ttyUSB0 make esp32-audio-flash PORT=/dev/ttyUSB0 make llm-telegram-flash PORT=/dev/ttyUSB0

Monitor Commands

make robocar-monitor-main PORT=/dev/ttyUSB0 make robocar-monitor-cam PORT=/dev/ttyUSB0 make esp32-webserver-monitor PORT=/dev/ttyUSB0

Clean Commands

make clean-all make robocar-clean make esp32-clean make llm-telegram-clean

Development Workflows

make robocar-develop-main PORT=/dev/ttyUSB0 make robocar-develop-cam PORT=/dev/ttyUSB0 make llm-telegram-develop PORT=/dev/ttyUSB0

Code Quality

make lint make lint-c make lint-python make format make format-check

Safety Checks

Before Flashing ESP32-CAM

• Remind user about GPIO0 → GND requirement

• Verify port is specified or use default

• Confirm device is connected

Before Clean Operations

• Confirm user intent (data loss prevention)

• List what will be cleaned

Port Validation

Common ports:

• macOS: /dev/cu.usbserial-*

• Linux: /dev/ttyUSB* , /dev/ttyACM*

• Windows: COM*

Prohibited Operations

This skill does NOT allow:

• Arbitrary shell commands

• File deletion outside build directories

• Network operations

• Git operations (use dedicated commands)

• System configuration changes

Usage Examples

Build a project

"Build the robocar main controller" → make robocar-build-main

Flash with specific port

"Flash the camera to /dev/ttyUSB0" → Remind about GPIO0, then make robocar-flash-cam PORT=/dev/ttyUSB0

Full development workflow

"I want to work on the telegram bot" → make llm-telegram-develop PORT=/dev/ttyUSB0

Check code quality

"Run the linters" → make lint
