Get click image

get_click_image
Read-onlyIdempotent

Return the before.webp or after.webp screenshot from a CLI click capture. Pass kind=before or kind=after.

Input Schema

NameRequiredDescriptionDefault
kindYesClick screenshot to read: before or after. The requested screenshot must exist in the capture.
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.
platformYesPlatform type ID from list_platforms.options.platforms[].id (backend CatalogPlatform.view). Use backend IDs verbatim; desktop/mobile are current examples. Environment is selected separately.
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.

TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint, so the safety profile is covered without the description. The description adds the concrete artifact naming (before.webp/after.webp) and that the source is a CLI click capture, but nothing about availability, error behavior, or fallbacks. The schema carries the 'must exist' precondition. A 3 is appropriate.

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 short sentences, zero waste, purpose front-loaded ahead of the parameter hint. Nothing is padded.

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 detail is not owed, and annotations plus a fully covered schema handle the rest. The remaining gap is that similar image-retrieval siblings are not disambiguated, which matters for this tool family.

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%, and the schema documents kind, product, platform, version, and environment thoroughly, including how to source IDs from list_platforms and list_versions. The description's 'Pass kind=before or kind=after' merely repeats the schema, so the 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 (Return) and resource (before.webp/after.webp screenshot from a CLI click capture), which scopes it well. However, the sibling list contains many near-identical image getters (get_capture_image, get_replay_step_image, get_page_image), and the description never distinguishes itself from 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?

The only routing information is 'Pass kind=before or kind=after,' which is an invocation instruction, not usage guidance. There is no statement of when to choose this over get_capture_image or the other *_image siblings.

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