Tip: Stack Token-Reduction Proxies to Cut Claude Code Usage by 90%+

Codepointer·high signal

Practitioners report stacking independent token-reduction layers — a model router, rtk (60–90% off Bash/tool output), Caveman (50–75% off model output), and the Headroom API proxy (47–92% off tool/RAG payloads) — to compound past 90% total reduction. The recommended order is measure first with ccusage for a week, then add one tool at a time (router → rtk → caveman) so you can attribute savings. For anyone running many agents daily on a subscription, this is the highest-leverage cost lever available right now.
