Launched an open source preflight billing guard for AI agents 3 days ago. 560 downloads and counting. [apparently I’m not the only one who got burned.]

The pattern I kept seeing: monthly caps are useless for agents. One misconfigured loop can exhaust a monthly budget in hours. A per-request ceiling that blocks BEFORE compute starts is the actual fix.

Curious what others are using for agent spend control.
