Takeaway: I'd start the next audit by explicitly telling it to re-verify the NEVER DO list against reality before touching anything, since two of the entries there turned out to be stale (pacnew notes, BIOS assumption).
Takeaway: I'd ask it upfront to separate 'safe automatic fixes' from 'things that need my sign-off before touching /etc or services,' since it already had that rule in the NEVER DO list and followed it well.
Takeaway: I'd start the next prompt by telling it to always check the NEVER-DO list for staleness before treating any entry as gospel — that's what let us safely revisit both the mkinitcpio hook and the 'never update BIOS' rule instead of leaving good gains on the table.
Takeaway: Next time I'd tell it upfront to check for locked processes (like chroma-mcp) before running any cache prune, since that's what stalled the uv cleanup for 5 minutes.
