PlateTaleWhy does the agentic web need reliability testing?
Every time software started talking to software, a testing discipline appeared alongside it. APIs got contract tests. Browsers got end-to-end suites. Agents on the open web have nothing yet.
The failure mode is silence
When an agent cannot finish a purchase, nobody files a ticket. The agent reports back vaguely, the customer shrugs and does it themselves or goes elsewhere. There is no error in your logs — just a request that stopped. You lose the revenue without learning that you lost it.
The dependency updates itself
You control your code. You do not control the models. A vendor changes how an agent interprets pages and your working journey fails with no deploy on your side. This is the first dependency most teams have that ships changes without telling them.
What a test suite looks like here
Real agents, real journeys, run on a schedule against production. A pass rate per journey. A trace of the step where each failure occurred. An alert when the rate drops. Conceptually it is uptime monitoring, except the thing being monitored is whether a task can be completed rather than whether a server responds.
Why now
Non-human traffic is already a large share of the web, and the portion of it acting on behalf of a specific person is growing. The cost of finding out late is a quarter of lost conversions you never attributed. That is the gap PlateTale fills.
