Create a presentation

create_presentation

Create a new presentation of yours, empty or complete in one call. "slides" is a list of {"name", "name_tr", "w", "h", "bg", "fit", "background", "objects": [blocks]}; blocks may link to each other's slides with {"kind": "slide", "slide_number": N} (1-based, in this list). Returns the new presentation with the ids of its slides and blocks (every prop too with "response": "full"). Every presentation is in all the languages of the site (ru, en) at once: write the texts in "lang" and give the other languages right away -- "title_tr", "name_tr" of every slide and "tr" in the props of every text, shape and button block ({"en": ""}); the layout is shared. The answer lists what is still "missing_translations".

Input Schema

Name	Required	Description
`lang`	No	The language "title", slide names and blocks' "html" are written in (default: the one most of the words of the title, the slide names and the texts are in).
`theme`	No	Default colours of the slides and of new blocks.
`title`	Yes	Title (at most 100 characters).
`access`	No	Who sees it (default "private": only you, until you publish it; "public": everybody reads it; "open": every signed-in person edits it too).
`slides`	No	Slides with their blocks (optional).
`project`	No	Slug of one of your projects to create the presentation in (at its end); its blocks may then lead to the slides of the other presentations of that project.
`database`	No	Setup scripts of the databases the runnable code blocks work in, by language. Every viewer runs the blocks in a private database made from the script (up to 50000 characters each; an empty string removes a script).
`response`	No	"brief" (default): only the ids, numbers and types of the slides and blocks; "full": every prop of every block too.
`title_tr`	No	The title in the other languages of the site: {"en": "..."}.
`description`	No	Description shown on the presentation page (optional).

Output Schema

Name	Required	Description
`id`	Yes
`url`	No	The address people open in a browser.
`lang`	No	The language its texts are written in; "tr" holds the others.
`slug`	Yes	The address of the presentation: /movie/<slug>/.
`owner`	No	User name of the author.
`theme`	No
`title`	Yes
`access`	No	open, public or private.
`slides`	Yes
`project`	No	The project it belongs to, or null.
`version`	No	Stamp of the content as it is now: give it back as "base_version" to change it only if nobody else did meanwhile.
`can_edit`	No	Whether you may change it.
`database`	No	Setup scripts of the databases of runnable code blocks (shown to the author only).
`title_tr`	No	The same text in the other languages of the site: {"en": "..."}.
`languages`	No	The languages of the site.
`cover_slide`	No	Id of the slide shown as its cover in the lists (null: an uploaded picture, or no slides).
`description`	No
`database_chars`	No	A part or the words only were read: how long each database script is (the whole presentation without "texts_only" gives them).
`missing_translations`	No	What is not translated yet into the other languages of the site (add it): the first ones; "missing_translations_count" says how many there are.
`missing_translations_count`	No	How many texts are not translated yet.

TDQS

A3.8/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly=false, destructive=false, idempotent=false, openWorld=false. The description adds substantial context beyond that: that every presentation exists in all site languages simultaneously, that translations must be supplied via *_tr fields and "tr" props, and that the response reports "missing_translations". It omits permission/auth prerequisites but the access enum in the schema covers visibility.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action, then the slides/blocks format, then the translation rule, then the return shape — a sensible ordering. It is dense and uses compact code-like notation mid-sentence, which slightly hurts readability but wastes little.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 10-parameter tool with nested slide objects and an output schema, the description covers the parts that are hardest to infer: the block/slide payload shape, slide-link syntax, the multi-language obligation, and what the response contains. Database scripts and theme defaults are left to the schema, which is acceptable given 100% coverage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3; the description earns above that by explaining the cross-slide linking convention ({"kind": "slide", "slide_number": N} is 1-based within the submitted list) and the response="full" behavior of returning every prop — semantics not fully conveyed by the schema alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Create a new presentation") plus meaningful scope: it can be created empty or fully populated with slides and blocks in one call. The phrase "in one call" implicitly contrasts with the create-then-add_slides path, though no sibling is named explicitly, keeping it short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is implied rather than stated — batching slides into creation, and writing all site languages up front. There is no explicit guidance on when to prefer this over import_presentation, copy_slides, or create-then-add_slides, and no stated prerequisites (e.g. upload_image first for backgrounds).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
