YakuShield
Stop your AI agent from quietly torching your budget.
Get Pro →Ever run into this?
You leave an AI agent running, come back, and it has burned far more tokens than you expected. The scary part isn't a bad diff — it's the bill you never saw coming.
The fix
A local proxy that physically 429s the agent the moment you hit your daily cap, plus a dashboard that shows exactly where tokens get wasted (including Japanese overhead).
What it does
- Hard budget breaker — 429s the agent at your daily cap
- Token-waste visibility, incl. Japanese overhead
- Works with Claude Code and Codex
