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.

After further playing with my LLM project, I'm surprised how hard it is to tune with system prompts. My agent kept saying "obviously" even though my prompt said "helpful, professional". Eventually I found that a "courteous" prompt gets "of course" which is better but not ideal.

Wonderful post from the lead LLVM maintainer reflecting on how the project is run, the design issues in LLVM today, and opportunities to make it better:
