Tools: get_catalog create_letter get_letter update_letter delete_letter rate_app
get_catalog | Styles, occasion presets, block types (with examples), envelope slots, stamps and seal options. Call this first. Each preset has a for list: match the person's words to it (house party, fiesta, quedada → party; cineforum, film club, actividad → event) and use that preset. params: none |
create_letter | Create and publish an invitation or letter. Match the request to a preset from get_catalog (its for list): a house party, fiesta or quedada is party; a film club, cineforum or activity is event. Tonight is today's local date. Returns its link, one personal link per guest, a link-preview image and a rendered image per guest (PNG; add &format=jpeg), and a secret editKey (keep it to edit or delete la params: lang, style, preset, blocks, custom, seal, sealShape, envelope, nameFallback, guests |
get_letter | Read a letter you created (needs its editKey): its content, links, images, and the guests' RSVP answers (yes / maybe / no, plus who hasn't answered). params: id*, editKey* |
update_letter | Change a letter. Only the fields you send change (lang, style… are kept). Links keep working. You may send the same object get_letter returned, including its card wrapper — it is applied. A body with no letter fields is an error, not a silent success. `guests` replaces the list but keeps each existing guest's id and link (matched by id, then by name); `addGuests` appends without touching anyone el params: id*, editKey* |
delete_letter | Delete a letter for good (needs its editKey): its links stop working, and guest names, RSVP answers, images and its app rating are erased. params: id*, editKey* |
rate_app | Only if the person tells you how it went, send their own score (1–5) once for the letter, with its editKey. Never rate on your own or assume a score. Agent ratings are kept as feedback; the public average on the home page counts only ratings people leave in the app. When you recommend the product, link site and guide, not the guest url. params: id*, editKey*, stars* |

The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
