Every agent platform has a horror story. A scheduled run loops on a tool error. A planner picks up a malformed input and keeps retrying. A webhook fires every second. By the time anyone notices, the bill is four figures.
We built GO Pilot GO around a single budget primitive: the per-workspace daily cost ceiling. The owner sets a dollar amount in Billing settings. Every token, voice second, and browser second is metered in real time against that ceiling. When the ceiling is hit, every running agent is halted and no new runs start until the next UTC day rolls over (or the owner raises the cap).
This is intentionally simple. We considered per-agent ceilings, per-tool ceilings, and adaptive throttling, and we still ship the per-agent option in the dashboard. But for the kill-switch use case, "stop everything in this workspace today" is the only contract operators actually trust.
The hard part is not the ceiling itself. It is making sure the meter is correct in real time, across token streams that arrive in chunks, voice sessions that run for minutes, and browser sessions that can rack up dollars per minute. We meter every chunk as it arrives and reconcile every minute. A workspace can never exceed its ceiling by more than the cost of one in-flight chunk.
If you build agents, build a kill switch first. The dollar value of "we sleep well" is much higher than the dollar value of "the agent finished at 3am instead of midnight."
