Field notes
The documented workflow starts by inspecting an endpoint and reviewing tool safety hints, then uses a read-only tool for a canary. Its examples show JSON arguments and assertions against returned data; the page also says the configuration can be reapplied by name in a deploy workflow. The CI test is described as returning JSON evidence and a failing exit code when a check does not pass.
