Show HN: ClaudeStatsBar: your session is 486k deep and nothing told you

ClaudeStatsBar is a Python tool that displays real-time statistics about Claude Code session costs in the status bar, showing context window usage, per-turn costs, and remaining time in rate-limit windows before users hit limits mid-task. The creator analyzed their own usage data (916 transcripts, 711 sessions) and found that sessions accumulate far more context than expected—with the median session carrying 193.3k tokens and 37% of sessions exceeding 150k context—making it essential to monitor costs proactively rather than discovering limits during work.
