Summary of the AI readings · beta

The service lists 7 capabilities, and 6 have AI readings.

6 capabilities are read as read-only, including list_guides, drink_window_for and find_similar_wines.

Rows named: list_guides · drink_window_for · find_similar_wines

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.

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
