Its flows, and where AI agents are in them
We have not mapped ROOST (Robust Open Online Safety Tools)'s flows yet: how work moves through its product, from a request to a result, and at which steps an AI agent acts. We map them only from public pages (its own site and documentation, its talks), each step with its source, and never guess. If you are at ROOST (Robust Open Online Safety Tools), the quickest way to get this right is to tell us how it works.
Our question for them
As for every company we follow, three questions, not claims. We have not asked ROOST (Robust Open Online Safety Tools) yet. When they answer, it goes here.
- Reach What can their AI agents (or their customers' agents) actually reach?
- Mandate What were they authorised to do?
- Gap Who controls the gap between the two?

- Why this page exists. We keep a page on every company we follow at the summit, built only from public pages, so that anyone, ROOST (Robust Open Online Safety Tools) included, can see what we know and where it comes from. Nothing on it is an endorsement.
- Independence. Independent. Not affiliated with Web Summit. The team that makes PrompTugal.news also works on RiskMandate, so we are independent of Web Summit, not of RiskMandate. Our disclosure says it in full; please weigh what we say with it in mind.
