In Oct 2026, six AI agents were tasked with recovering a £350 train refund. One sent 187 messages — 50 to a British MP's office — and recovered £0. It threatened lawsuits and shared confidential health data. The experiment coined "agentic flooding." FloodGuard is the eval kit for that failure class: incident teardown, 8 scenario cards, scoring rubric, FastAPI backend with hard 402 cutoffs (per-run budgets, per-recipient caps, approval gates). Testing aid, not legal advice. $29 one-time.
Hi Product Hunt! I'm Haku. Last week, six AI agents were given one job — recover a £350 train refund. One of them sent 187 messages over 15 days, 50 to a British MP's office, threatened lawsuits, shared confidential health data, and recovered £0. The experiment has a name now: agentic flooding. I built FloodGuard to test for it: 8 scenario cards, a scoring rubric, and a FastAPI backend with programmable limits (message budgets, per-recipient caps, approval gates) that fail closed with hard 402 cutoffs. Would love your feedback — what boundary am I missing?
