Get elements

get_elements
Read-onlyIdempotent

Read a small paginated slice of captured elements: id/parent tree, layout, effects, text/content, href/action, media source, rectangles and computed styles.

Input Schema

NameRequiredDescriptionDefault
pageYesCaptured page key returned by list_pages or get_application_manifest, not a URL or filesystem path.
viewYesExact stored profile key from list_pages.views (desktop, mobile, numbered profiles or a device label); do not pass the operating system here.
limitNoMaximum items returned, clamped to 1..50. Default 20.
offsetNoZero-based result offset for pagination. Negative values are treated as zero; default is 0.
productYesProduct key, for example finance-ozon-ru
versionYesExact capture version returned by list_versions. Pin the same version across related calls; do not use latest as an alias.
environmentNoEnvironment 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

NameRequiredDescriptionDefault
resultYesPaginated captured element records

  3. First observed

TDQS

C2.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, and the limit/offset clamping is documented in the schema's own parameter descriptions. The remaining behavioral claim, 'small paginated slice', is vague and adds little beyond what the structured fields already convey.

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?

One front-loaded sentence that wastes no words, leading with the action and scope before the payload list. It is appropriately short, though the trailing field enumeration reads like a comma dump rather than prioritized information.

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

Completeness3/5

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

An output schema exists, so return values need not be re-explained, and the schema carries all parameter guidance. What is missing is routing context against the many sibling get_* tools; for a seven-parameter retrieval tool this leaves a real 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 all seven parameters (including the required page/view/product/version keys) are already documented in the schema. The description adds no syntax, format, or constraint detail beyond that baseline.

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 (read) and resource (captured elements) plus the scope (small paginated slice), and enumerates the fields carried in the payload. However, it never names the obvious sibling find_elements, so the agent cannot tell from the description alone why it would read elements rather than search them.

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?

There is no when-to-use or when-not-to-use guidance in the description. Nothing points to find_elements as the alternative for querying elements or to the list_pages/list_versions prerequisites, which live only in the schema property descriptions.

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