Summary of the AI readings · beta

The service lists 5 capabilities, and 4 have AI readings.

4 capabilities are read as read-only, including how_it_works, list_upcoming_dinners and get_dinner.

Rows named: how_it_works · list_upcoming_dinners · get_dinner

Written by code from the AI readings on this page: it groups them and says nothing they do not.

The atlas shows each capability by its plain identifier, inputs and declared sign-in. Publisher descriptions, paths, links and source evidence are not published here.

A2A skills 0+ observed

Inventory incomplete. The displayed count is a lower bound; missing items do not prove removal.

A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
