Just make sure you never let claude make do any calculation without using a programming language. It can be somewhat trusted to make less mistakes than a human when it comes to filling in the right numbers but it's still not great at math.

100% this! This is why I explicitly mentioned in my CLAUDE files to generously use Python for any calculations using the virtualenv. It was also my first time using Claude for tax related calculations so I did cross-check it against an online ACB calculator https://www.adjustedcostbase.ca
