How it works

TokenKing is built with TypeScript and uses ccusage as a dependency to read Claude Code session data. It loads all sessions, filters by project path (with support for moved directories via basename matching), then aggregates and displays the results.

Dependencies

• ccusage - Reads Claude Code session data from ~/.claude/projects/
• picocolors - Terminal colors for output formatting
