How to Close the AI Agent Cost Gap at the Call Site

Last week I wrote about for exactly this. It is an open-source runtime budget, token, and rate limiter for AI agents. You wrap your agent loop, set a dollar cap, and it stops the run before the bill does. pip install agentguard and you can put a cap on your worst offender in about ten minutes.

The cost gap is real. But it is not a mystery. It is three leaks you can plug at the call site today.
