Claude Code Statusline: monitoring rate limits in real time

Claude Code rate-limits its users. Not brutally — with overlapping quotas: active context window size, session quota, weekly quota, per-model quotas. The problem: no visibility without typing /usage in the interface, which means breaking out of the workflow, reading formatted text, memorizing numbers, and resuming. During an intense development session, this happens often, and it's always at the worst moment. The initial idea was simple: the equivalent of a tmux powerline, but for Claude Code quotas. A bar at the bottom of the screen, always there, updated in the background. Result: a Bash script, built with Claude Code itself during a single session, that displays claude code rate limit status information permanently without ever blocking the active terminal.
