There's something pleasingly self-referential about configuring an agent by talking to it. > Remember that [fact about data formats]. Agent: Noted. ... realise nothing happened ... > Write to your rules file that when I say "remember", I want you to write to the rules file.

One nice feature of cargo that I wasn't previously aware of: you don't need to do anything after updating your Cargo.toml. In npm, you need to remember to `npm i` after changing package.json. It's not declarative and the state can get out of sync.

I struggle with dependency syntax. I never remember what ^1.2.3 means or how it differs from ~1.2.3. I believe both npm and cargo assign the same meanings to this notation, but it's less obvious than e.g. 1.x. 1.2.3 isn't an exact version constraint either!
