Get component

get_component

Read-onlyIdempotent

Return one component candidate and its descendants. Prefers the id/parent tree; falls back to rectangle containment. Includes a crop rectangle for the page image.

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.
`limit`	No	Maximum items returned, clamped to 1..200. Default 100.
`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.
`elementId`	Yes	Zero-based captured element ID from find_elements or get_elements. 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.

Output Schema

Name	Required	Description	Default
`result`	Yes	Root element and bounded descendant evidence

TDQS

A3.6/5.0

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 genuine behavior beyond that: the two-tier resolution strategy (id/parent tree preferred, rectangle containment fallback) and the fact that a crop rectangle for the page image is included in 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?

Three short sentences, zero filler, and the core behavior (what is returned) is front-loaded before the resolution and crop-rectangle details.

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?

With an output schema present, return-value explanation is unnecessary, and the rich schema covers parameter semantics. The description supplies resolution behavior and crop-rectangle output, leaving only the sibling-selection routing gap.

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 baseline is 3; every parameter (page, view, version, elementId, environment) is already documented in the schema with usage warnings. The description adds nothing about parameter syntax or constraints beyond that.

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+resource (return one component candidate and its descendants) and adds scope detail about the fallback resolution. It does not name or contrast with close siblings like get_component_tree, get_page_components, or list_component_candidates, so an agent can't distinguish them from the description alone.

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

Usage Guidelines2/5

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

No when-to-use or when-not-to-use guidance. The 'prefers the id/parent tree; falls back to rectangle containment' line describes internal resolution behavior, not the conditions under which an agent should pick this tool over the many sibling component/element retrieval tools.

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