Spend cap

In practice

The distinction between a cap that stops and an alert that warns is the whole point. An alert is a report about money already spent, and it arrives while the mechanism that spent it is still running, which is fine when a person is watching and useless for an agent running over a weekend. Prepaid balances enforce this structurally: zero is a real floor, so the worst case is a paused agent rather than an invoice. Overruns almost never come from high per-call prices. They come from retry loops, context that grows every run, and tasks that fan out over a longer list than expected.
