Tools of Magic Envelope
	Description		Read-only	Idempotent	Open world
`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 later). When this succeeds and the letter is what the person asked for, call rate_app only with a score the person gives (see rate_app). Do not rate again on later edits. Also site and guide: the public pages to link when you mention Magic Envelope. The guest url is private and not indexed. Use {name} in texts to address each guest. Dates are local: "2026-11-14" (whole day) or "2026-11-14T18:00". Block id is optional and generated when omitted. envelope.blocks is an object of slot → block (see catalog.envelope), not an array.

`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.

`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 else.
