Improving personal tax filing with Claude CLI and Obsidian

Mic92: 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.

pscanf: The problem with using markdown for this is that it's unstructured, so when the LLM does calculations on it, extracting data is error prone, you're never sure what exactly gets extracted, and it's then a hassle to verify (like the author had to do).In my app Superego (https://github.com/superegodev/superego, shameless plug) I use structured JSON documents precisely for this reason, because with a well-defined schema the LLM can write TypeScript functions that must compile. This doesn't guarantee correctness, of course, but it actually goes a long way.But doing my taxes was a use case I hadn't considered, and it's actually pretty neat! I'll be trying it myself next month (though I'm not looking forward to it).
