Details from the Claude Code 2.1.216 update reveal a 14.0% increase (+3,099 tokens) in system prompt tokens. The system prompt mix rose significantly from 38.4% to 52.3%, while the tools mix dropped to 47.7%. The update also removes a stray Bun HMR error log to reduce prompt noise and prevent Claude from shifting focus to frontend hot-reload fixes.
