I'm adding uptime data to my personal LLM bot. Does this information belong in the system prompt? That was my initial plan, but I'm thinking that a tool would be better. Tools let me see information provenance ("queried the uptime tool"). There's also a small caching benefit.

It seems really odd to me that git uses 'cached' terminology for staging. For example, `git add somefile.rs; git diff --cached`. Caching implies state that you don't mind losing. There's very little state I want to lose in version control!
