Real-time token usage and cost analytics for Claude Code. Automatically tracks spend per developer, project, and session via a PostToolUse hook. Includes budget enforcement with daily/weekly/monthly caps and macOS notifications, multi-model pricing (Sonnet 4.5, Opus, Haiku), a slash command for instant cost reports, a conversational agent skill for natural-language cost queries, and an optional full Next.js analytics dashboard.
