See exactly what's burning your Claude Code quota — **live**.

Real-time token attribution for Claude Code sessions. Shows burn rate, quota progress, and a per-source breakdown: by tool, agent, skill, and MCP server.

The problem

You're running Claude Code and suddenly you've burned through your quota. But *what* consumed it?

• A skill that reads 40k tokens of context on every turn?
• An agent spawning sub-agents that each spin up their own context?
• An MCP tool hitting a large endpoint repeatedly?
• Long Bash output being read back into the model?

The built-in `/stats` command shows a total percentage — but no breakdown. **claude-token-lens** reads the same session files Claude Code writes and shows you a live, per-source attribution table.
