Token Tracking & Cost Monitoring
Real-time monitoring of Claude API token usage, cost, and rate limits across sessions. A pipeline that captures per-message token data from Claude Code, logs it to structured files, and surfaces it in a desktop overlay with charts and alerts.

Why It Matters
Claude subscriptions enforce rate limits across two windows — a 5-hour rolling window and a 7-day rolling window. Without tracking:
- You hit rate limits unexpectedly and lose momentum mid-session
- You can't tell which sessions or tasks burn the most tokens
- Cost optimization is guesswork — you don't know where to apply caching or model routing
- No historical data means no trend analysis or capacity planning
Visibility into token flow turns a black box into an optimizable system.
