I had the same suspicion so made this to examine where my tokens went. Claude code caches a big chunk of context (all messages of current session). While a lot of data is going through network, in ccaudit itself, 98% is context is from cache. Granted, to view the actual system prompt used by claude, one can only inspect network request. Otherwise best guess is token use in first exchange with Claude. https://github.com/kmcheung12/ccaudit

What is the system prompt for $1000 Alex (RIP)?
