"Implements + tests against sqlite3 as oracle"

That's the real unlock in my opinion. It's effectively an automated reverse engineering of how SQLite behaves, which is something agents are really good at.

I did a similar but smaller project a couple of weeks ago to build a Python library that could parse a SQLite SELECT query into an AST - same trick, I ran the SQLite C code as an oracle for how those ASTs should work: https://github.com/simonw/sqlite-ast

Question: you mention the OpenAI and Anthropic Pro plans, was the total cost of this project in the order of $40 ($20 for OpenAI and $20 for Anthropic)? What did you pay for Gemini?
