Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Voltage and Power Traps
3.3V vs 5V logic mixing damages boards โ ESP32 is 3.3V, Uno is 5V, level shifter required USB provides max 500mA โ not enough for motors, servos, or many LEDs Never power motors from Arduino 5V pin โ use external supply with common ground Brown-out causes random resets โ looks like code bugs, actually insufficient power Decoupling capacitors (0.1ยตF) near sensor power pins โ reduces noise-related glitches
Wiring Mistakes
Floating inputs read random values โ always use pullup or pulldown resistor All components must share common ground โ separate grounds = nothing works Long wires pick up noise โ keep analog sensor wires short LEDs need current limiting resistors โ direct connection burns LED and pin Reversed polarity destroys components โ double-check before powering on
Pin Conflicts
RX/TX pins (0, 1) conflict with Serial โ avoid for GPIO when using Serial Monitor Some pins have special functions โ check board pinout for I2C, SPI, interrupt-capable pins PWM only on pins marked with ~ โ analogWrite() on wrong pin does nothing Internal pullup available โ INPUT_PULLUP eliminates external resistor for buttons
Timing Traps
delay() blocks everything โ nothing else runs, no input reading, no interrupts serviced millis() for non-blocking timing โ compare against last action time millis() overflows after ~50 days โ use subtraction: millis() - lastTime >= interval Interrupts for time-critical events โ attachInterrupt() responds immediately
Memory Constraints
Uno has only 2KB RAM โ large arrays fail silently with weird behavior F() macro keeps strings in flash โ Serial.println(F("text")) saves RAM PROGMEM for constant arrays โ keeps data out of RAM String class fragments heap โ prefer char arrays for stability
Serial Debugging
Baud rate must match โ mismatch shows garbage, not an obvious error Serial.begin() required in setup โ output before this goes nowhere Serial printing slows execution โ remove or reduce for production code
Upload Problems
Wrong board selected โ uploads but doesn't run correctly Serial Monitor holds port โ close before uploading USB cable might be power-only โ some cheap cables don't carry data Bootloader corrupted โ reflash using another Arduino as ISP
Sensor Communication
I2C devices share bus โ check for address conflicts with scanner sketch 5V sensors on 3.3V boards give wrong readings or damage โ check operating voltage SPI needs separate CS per device โ can't share chip select lines
Category context
Code helpers, APIs, CLIs, browser automation, testing, and developer operations.
