Auto-retry Claude Code sessions when hitting Anthropic subscription rate limits. Uses tmux monitoring + send-keys to detect rate limit messages, wait for reset, and send "continue" automatically. Zero dependencies, zero workflow change. - Shell wrapper intercepts `claude` command transparently - Background monitor polls tmux pane for rate limit patterns - Timezone-aware reset time parsing with DST safety - Safe send-keys with foreground process verification - --print mode: buffers output, retries cleanly for pipes - Config validation prevents bad values from causing crashes - 59 tests, 0 dependencies Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
