Python script that Claude Code wrote and I tweaked for peeking at marked USB-C cables: https://github.com/nhecker/usb-e-marker

For your last point, you're probably looking for something like `ioreg -raw0 -c AppleSmartBattery | plutil -extract 0.PowerTelemetryData.SystemPowerIn raw -` (The source for that last command is from the above gist: https://gist.github.com/nhecker/8e850773ff229724ce361967cc22... ) Or maybe `pmset -g ac | head -n3` is helpful, too. HTH.
