Get component typography

get_component_typography

Read-onlyIdempotent

Read grouped text font styles for one component ID with counts and sample element IDs. Paginated and optionally limited to a y range; use get_fonts for family names and origin URLs.

Input Schema

Name	Required	Description
`page`	Yes	Captured page key returned by list_pages or get_application_manifest, not a URL or filesystem path.
`view`	Yes	Exact stored profile key from list_pages.views (desktop, mobile, numbered profiles or a device label); do not pass the operating system here.
`yEnd`	No	Non-negative vertical end coordinate in captured CSS pixels; default 0 selects one viewport from yStart. A vertical fragment may span at most two viewport heights.
`limit`	No	Maximum items returned, clamped to 1..50. Default 20.
`offset`	No	Zero-based result offset for pagination. Negative values are treated as zero; default is 0.
`yStart`	No	Non-negative vertical start coordinate in captured CSS pixels; default 0. When both bounds are 0, component layers use the component bounds and page layers use the first viewport.
`product`	Yes	Product key, for example finance-ozon-ru
`version`	Yes	Exact capture version returned by list_versions. Pin the same version across related calls; do not use latest as an alias.
`componentId`	Yes	Captured root element ID from get_page_components or get_page_outline. Must belong to the selected page, view and pinned version.
`environment`	No	Environment ID from the selected backend platform type in list_platforms.options.platforms[].environments[].id (backend implementation). Omit only when the version has one captured environment. Use captured pairs from list_platforms/list_versions for actual availability.

Name	Required	Description	Default
`result`	Yes	Paginated deduplicated typography

A4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds behavioral context beyond that: pagination, optional y-range limiting, and the grouped/count/sample-ID nature of the result.

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?

Two tight sentences with zero filler, front-loading what the tool reads before noting pagination/range behavior and the sibling alternative.

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?

An output schema exists, so return-value explanation is not required, and annotations cover safety. The description is nearly complete for a read tool; the only gap is that it does not differentiate from the other component-level get_component_* siblings.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all ten parameters including defaults, clamps and coordinate semantics. The description mentions component ID, pagination and y-range only in passing, adding no syntax or format detail beyond the schema. Baseline 3 applies.

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 ('Read grouped text font styles for one component ID') plus the return shape (counts and sample element IDs). It names get_fonts as the tool for family names/URLs, routing away from one sibling, but it does not distinguish itself from the closely-named get_component_styles or get_component_text.

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?

Gives clear usage context (paginated, optionally bounded by a y range) and points to get_fonts when family names or origin URLs are needed. No explicit when-not conditions or prerequisites are stated, but the routing to the alternative is helpful.

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