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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuine value beyond that by disclosing what the result contains (rating place, context, gateway price, page URL), which is not derivable from any structured field since there is no output schema. It omits any note on result ordering or the limit's effect, which keeps it from a 5.

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 front-loaded sentence opening with the action verb, followed by a compact enumeration of returned data. No filler, no repetition, and the most decision-relevant information comes first.

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?

With no output schema, the description carries the burden of explaining return values and does so adequately. Annotations cover the safety profile, and the schema covers parameters, so the remaining gaps are minor: no note on result ordering, pagination, or what happens when no model matches.

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 all three parameters — query, limit, only_gateway — are already documented in the schema. The description largely restates the query semantics (name or developer) and gestures at the gateway filter via the price mention, but adds no new syntax, matching rules, or limit behavior beyond what the schema provides. Baseline 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 gives a concrete verb and resource ("Найти нейросеть по названию или разработчику") and enumerates the fields returned — rating position, context, IRI Gateway price, page link. That is enough to distinguish it from the narrower siblings get_model_rating and get_gateway_prices, though it never names them explicitly.

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?

Usage is only implied: the search-by-name-or-vendor framing plus the mention of rating and price suggests this is the broad discovery entry point, with the sibling tools as drill-downs. There is no explicit statement of when to prefer it over get_model_rating or get_gateway_prices, and no prerequisites or exclusions are given.

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