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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that returned items include statuses and text, but says nothing about pagination behavior despite limit/offset parameters, leaving a meaningful gap for a list tool with no output schema.

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

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

A single short, front-loaded sentence with no filler. It is efficient, though arguably too terse to earn full marks given the tool's five-parameter surface.

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

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

For a five-parameter, zero-required list tool with no output schema and only readOnly/openWorld annotations, the description is minimal. It hints at return content (statuses and text) but omits pagination behavior and the relationship between the states and statuses filters, leaving the agent to rely wholly on the schema.

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

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

Schema description coverage is 100%, so every parameter (limit, offset, states, statuses, ad_extension_ids) is already documented in the schema. The description adds no syntax, format, or filter semantics beyond that, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Получить') and resource ('уточнения (callouts)'), and the bilingual gloss disambiguates the term. It does not explicitly distinguish itself from the add_ad_extensions/delete_ad_extensions siblings, but the read/list nature is clear from the name and description together.

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

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

The description offers no guidance on when to use this tool versus alternatives such as add_ad_extensions, delete_ad_extensions, or the sitelink listers. No prerequisites or exclusions are stated; usage must be inferred entirely from the name.

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