L0 · Public web only: AI agent use cases
Needs no logins. The agent only reads public web pages and open data.
L0 cases need no account access at all: the agent only reads public web pages and open data. They are the safest way to try an agent, and every pilot re-run on triedagents is L0.
In plain words: Needs no logins. The agent only reads public web pages and open data. Access levels run from L0 (public web only) to L4 (spends money, deletes or escalates); the higher the level, the more you are trusting the agent. We rate the highest level a case actually needs. Full rubric.
