If you run Cursor or Claude Code hard, you already know the shape of the bill:
The session feels cheap while you're in the loop.
The meter (or the invoice) shows up later.
By then the damage is done — or you're rate-limited mid-task with no useful receipt for finance.
Cloud FinOps solved a version of this years ago: budgets that only notify aren't a control plane. Agentic coding has the same gap. Autoscale had traffic as a natural ceiling. An agent spends on intent. There's no gentle slope — just a wall.
