Add, change or delete blocks

edit_blocks

Change some blocks of a slide and leave the others alone, in one step: "add": new blocks [{"type", "props"}] (placed on top, or at the bottom with "at_bottom": true); "update": [{"id", "props"}] -- only the given props change. The same props for several blocks at once, like selecting them in the editor: {"ids": [...], "props"}; or for a card and everything drawn on it: {"inside": <id of the card's background block>, "props"} -- that block and every block lying within its rectangle (props a block type does not have, like "link" of a code block, are skipped for it); "delete": [block ids]. Returns the slide (ids only unless "response" is "full").

Input Schema

NameRequiredDescriptionDefault
addNoNew blocks: [{"type", "props"}].
slugYesThe presentation's slug (its address: /movie/<slug>/).
deleteNoIds of blocks to delete.
updateNoChanges: [{"id" | "ids": [...] | "inside": <card block id>, "props"}].
responseNo"brief" (default): only the ids, numbers and types of the slides and blocks; "full": every prop of every block too.
slide_idYesThe id of a slide (stable, the "id" of the slide in the presentation). Its number (position) changes when slides are reordered.
at_bottomNoPut the added blocks under the others (default: on top).
base_versionNoOptional: the "version" of the slide as you read it. The change is refused (409 conflict) when somebody changed the slide meanwhile, instead of overwriting their work.

Output Schema

NameRequiredDescriptionDefault
hNo
wNo
bgNo
idYesStable id of the slide.
fitNo
urlNoThe address people open in a browser.
nameNo
notesNoThe speaker notes (for those who may edit; only when there are some).
numberYes1-based position; changes when slides are reordered.
name_trNoThe same text in the other languages of the site: {"en": "..."}.
objectsYesBlocks, bottom to top ("props" only in the full form).
versionNoStamp of the content as it is now: give it back as "base_version" to change it only if nobody else did meanwhile.
backgroundNoThe "src" of the background picture, or null.
transitionNoEntrance effect of this incoming slide.
layout_warningsNoHow the changed slides will probably look: texts too long for their blocks, blocks outside the slide, texts over each other (estimated -- look at them).
transition_durationNoAnimation milliseconds, not auto advance.
missing_translationsNoWhat 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_countNoHow many texts are not translated yet.

  9. First observed

TDQS

A3.5/5.0
Behavior1/5

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

The description explicitly supports deleting blocks, including a "delete": [block ids] operation and the title "Add, change or delete blocks", but the annotations declare destructiveHint=false. That is a direct contradiction about whether the tool performs destructive updates.

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

Conciseness5/5

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

The description is front-loaded and organized around the three operations. Despite covering a complex multi-mode tool, every sentence adds operational detail and there is little wasted text.

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?

Given the rich schema, 100% description coverage, and output schema, the description covers the essential operation semantics well. It does not discuss base_version conflict behavior, but the schema already documents that parameter and the contradiction lies primarily in behavioral transparency.

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 coverage is 100%, so the baseline is 3. The description adds meaningful semantics beyond the schema, especially for update modes: only supplied props change, multiple ids can share props, and "inside" targets a card background plus all blocks within its rectangle while skipping unsupported props.

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?

The description states a specific resource and set of verbs: add, update, and delete blocks of a slide, while leaving other blocks untouched. It is clear what the tool does, though it does not explicitly distinguish itself from siblings like update_slide or edit_slides.

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

Usage Guidelines4/5

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

The description gives clear usage context: use it to change some blocks of a slide in one step while leaving the rest alone. It explains the three operation modes, but it does not name alternatives or state when not to use this tool versus sibling tools.

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