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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses almost nothing: no mention that it is a read-only retrieval, no pagination/limit behavior, no engine or device scoping, no indication that the payload selects among nine distinct datasets. 'Retrieve' weakly implies read-only, but that is the only signal.

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 eight-word sentence with no wasted clauses, but its brevity comes from under-specification rather than tight writing. It is front-loaded but too thin for the tool's complexity.

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?

An output schema exists so return values need not be explained, but for a tool with a required nested payload, nine operations, a filter DSL, and pagination options, this one-line description leaves an agent without enough to invoke it correctly.

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 effectively 0% at the top level (a handful of nested fields carry their own descriptions), and the description adds no meaning about the payload wrapper, the operation enum, the filters DSL, or ordering. Given the low coverage the description should have compensated and does not.

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 names a verb ('Retrieve') and a resource ('structured search result pages') but 'search features' is vague and the definition never distinguishes this tool from the many sibling search tools (web-search, ai-search-data, social-*-search, search-ads-data). An agent cannot tell from this text which search surface this covers.

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?

There is no statement of when to use this tool versus the large sibling set, no prerequisites, and no mention of the nine operations (organic, maps, news, images, etc.) that determine its behavior. Only the tool name implies usage.

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