edit_pageChange part of a design that already exists, the way you edit a file: each edit replaces exact text from read_page (it must appear exactly once) with new text.No findings
Why it is in this group
- The name "edit_page" says "edit": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Change part of a design that already exists, the way you edit a file: each edit replaces exact text from read_page (it must appear exactly once) with new text. Use it for any change the person asks for in an existing design — a headline, a colour, a picture, moving or removing something — instead of sending the whole page again: everything you do not touch stays as it is, the person's own edits included, and they see the change in their editor at once and can undo it. One page per call, or shared: true for the code every page shares. A refused edit changes nothing and says why. The reply shows the page as it looks now.

submit_deckReplace the whole file of a deck whose pages are all written (while pages are still being written, submit_page each one — a whole file is refused then).No findings
Why it is in this group
- The name "submit_deck" says "submit": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Replace the whole file of a deck whose pages are all written (while pages are still being written, submit_page each one — a whole file is refused then). Renderball checks it against the brief, renders every page and opens it in the editor. Returns 'ready' with the editor_url, or 'importing' — then poll deck_status.

- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Save one page you wrote (page 1: the file with Section0 and the shared design; page N: only its Section), with its direction (one sentence: the thing, the motion that acts out the claim, one craft detail). A page is accepted only after its brief was handed to you. The reply carries the next page's brief; when every page is saved the deck is merged, checked and rendered and the reply carries the rendered pages. To rewrite one page of a finished design, submit just that page: it replaces that page only, and everything else stays as it is, the person's own edits included. To change part of a page, read_page and edit_page are lighter.
Annotations the server declares

write_outlineSave a new page-by-page outline for a deck (pages written for the old one are dropped).No findings
Why it is in this group
- The name "write_outline" says "write": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Save a new page-by-page outline for a deck (pages written for the old one are dropped). The reply carries PAGE 1'S BRIEF; each submit_page reply carries the next page's.
Annotations the server declares
- title: Write the outline

create_deckStart a new presentation from a brief, the brand and your outline.No findings
Why it is in this group
- The name "create_deck" says "create": a word for a change.
Description, as the server wrote it Start a new presentation from a brief, the brand and your outline. The brand: if you can open the brand's website, read its real colours and fonts there first and declare them — the lead colour is usually the main buttons and the large coloured areas, not the link colour — and always give the website; never invent a colour. With the outline the reply carries PAGE 1'S BRIEF; write page 1 and send it with submit_page — each reply carries the next page's brief.
Annotations the server declares

What this check looks forMatched text
annotations: {"readOnlyHint":false,"destructiveHint":false,"openWorldHint":false}; The name "get_page_brief" says "get": a word for reading.
Description, as the server wrote it The full writing brief for ONE page: the studio's method, the rules, the examples chosen for that page, and (after page 1) page 1's file to continue. You rarely need it: page 1's brief comes with create_deck and each submit_page reply carries the next page's. Use it for a helper that writes one page with nothing in front of it.
Annotations the server declares

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it The deck's rendered pages as images, page 1 first — look at them for overlapping or clipped text, odd spacing, an element off its page or a picture that does not say its page's claim, then fix that page and submit_page it again. Available once the deck has been rendered.

Description, as the server wrote it Up to 4 of the studio's example pages, by the ids listed in a page brief — read the ones that fit the page you are about to write.

Why it is in this group
- The name "list_decks" says "list": a word for reading.
Description, as the server wrote it The user's Renderball documents, newest first, with editor links. Needs an account (a key). The design open in the person's editor right now comes first, marked open_now.

read_pageRead one page of a design as it is NOW — the code the person's editor shows, including their own edits — before changing it.No findings
Why it is in this group
- The name "read_page" says "read": a word for reading.
Description, as the server wrote it Read one page of a design as it is NOW — the code the person's editor shows, including their own edits — before changing it. Use it whenever the person asks to change something in a design that already exists: their editor may hold edits you have not seen. The reply carries the page's code, the code every page shares (palette, fonts, helpers), the page's element ids and, when the person has the design open, the element they selected ("this").
Annotations the server declares
- title: Read one page
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
