DotSpend: Guardrails for always-on agents: 402 cutoffs + kill switch

Hi, I'm vittoriali — I build guardrails for people shipping LLM agents. OpenAI's DevDay yesterday answered every question about dots except the one that keeps me up: what does an unattended task cost? So I did the math and built the kit I wanted to exist. DotSpend: per-agent spend caps with hard 402 cutoffs, an account-level kill switch, a sourced pricing table, and the runbook for leaving a dot alone overnight. The demo projects your task's unattended bill in the browser — no signup. Related tools I ship: ControlCheck (audit your agent controls) https://vittoriali.gumroad.com/l... and ShipSafe (the full LLM guardrail starter) https://vittoriali.gumroad.com/l.... Happy to answer anything about the guardrail pattern or the pricing math.
