ClaudeTokenVampire — Token Usage Monitor

Launch ClaudeTokenVampire to monitor your Claude Code 5-hour session token window. Windows only. Runs as a system-tray app.

Start-Process "${CLAUDE_PLUGIN_ROOT}/bin/ClaudeTokenVampire.exe"

ClaudeTokenVampire shows:

• Total tokens in the current 5-hour session (input + output + cache)
• Per-bucket bar chart spanning session_start -> session_end, color-coded by usage level
• Cache hit rate and cache tier status (warm/cold)
• Estimated cost based on configurable per-million rates
• Time until the session hard-resets (single reset, not per-message expiry)
• Per-project breakdown
