### Tool changes

- 2026-10-14 `search_registry` changed (description)
  - before: Searches Cellarion's shared wine database (vintage-neutral wines, community data) by name, producer, region or grape. Returns up to 10 matches. Call to identify a wine the user mentions, before recommending, or to check whether a wine exists in the registry. This searches ALL known wines — use search_bottles for what the user owns.
  - after: Searches Cellarion's shared wine database (vintage-neutral wines, community data) by name, producer, region or grape. Returns up to 10 matches. Call to identify a wine the user mentions, before recommending, or to check whether a wine exists in the registry. This searches ALL known wines — use search_bottles for what the user owns. A signed-in user's own drinks that are not wine (beer, cider, soft drinks — hidden from the shared registry) are listed first with only_in_your_cellar: true, so they can add more of them.

## Tools (7)

- `drink_window_for`: Sommelier-curated drink windows for a registry wine: per vintage, when it is young, at peak, and in late maturity, with where the vintage stands right now. Call for "when should I drink <wine> <vintage>", aging questions, or buy-now-drink-later advice. Only sommelier-REVIEWED vintages are returned — an empty result means no curated window exists yet (reason from grape/region/structure yourself, and say it is an estimate).
- `find_similar_wines`: Given a registry wine_id (or, on an authenticated connection, one of the user's bottle_ids), returns wines with the closest taste/style profile from the shared registry, using vector similarity over wine embeddings. Call for "more like this", "what else is like my favourite Barolo", or to seed purchase ideas from a wine the user loves. Only wines that have been embedded are searchable — an empty result does not mean nothing similar exists. Ids must be 24-hex Mongo ids from search_registry or search_bottles — a name or slug is not an id. Returns at most 10.
- `get_source_info`: Returns what Cellarion is, the version this instance is running, the open-source repository, and the license. Call this when the user asks what Cellarion is, which version they are on, whether it is open source, where to find / contribute to the code — or how to support the project.
- `get_wine`: Full registry record for one wine: producer, region, appellation, classification, grapes, community rating, the AI tasting profile when the wine has been enriched, and the registry image (url + credit) when one is published — null means the wine has no public picture yet; to see the picture yourself, call get_photo with the wine_id. Vintage-neutral (bottles carry the vintage). For signed-in callers, pending_correction says whether a correction suggestion is awaiting review on this wine (one is allowed per wine, across all users), which fields it covers and whether it is the caller's own — check it before composing suggest_wine_correction. Call after search_registry when the user wants depth on a specific wine.
- `list_guides`: Cellarion's published guides and blog articles (cellar management, drink windows, storage, buying) — title, slug, excerpt and tags. Call when the user wants a how-to or background reading; follow with read_guide for the full text.
- `read_guide`: The full text of one published Cellarion guide or blog article, by slug (from list_guides). Public website content — quote or summarise freely, and link the public_url when pointing the user to it.
- `search_registry`: Searches Cellarion's shared wine database (vintage-neutral wines, community data) by name, producer, region or grape. Returns up to 10 matches. Call to identify a wine the user mentions, before recommending, or to check whether a wine exists in the registry. This searches ALL known wines — use search_bottles for what the user owns. A signed-in user's own drinks that are not wine (beer, cider, soft drinks — hidden from the shared registry) are listed first with only_in_your_cellar: true, so they can add more of them.
