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

Annotations already declare readOnlyHint and idempotentHint, so safety is covered. The description adds genuinely useful behavioral context beyond them: the source is gol24.uz, names are in Uzbek Latin spelling, and spelling variants are matched automatically, which changes how an agent should phrase input.

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?

Two compact sentences, front-loaded with the source and scope, and the spelling guidance is placed where it is needed. Slightly dense parenthetical list of examples, but nothing is wasted.

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 only two params, no output schema, and annotations covering safety, the description supplies what is missing: source identity, entity scope, and input-spelling behavior. Return format and pagination are left unstated, but limit is fully covered by 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 coverage is 100%, so the baseline is 3, but the description adds meaning the schema lacks about the required 'person' argument: expected Uzbek Latin spelling with live examples and automatic variant matching. It does not add anything for 'limit', which the schema already documents fully.

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+resource ('Latest gol24.uz news about one person') and scopes the entity type to player, coach, or journalist, which clearly separates it from club- or topic-scoped siblings. It does not name an alternative tool explicitly, so it stops short of a 5.

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: an agent can infer it fetches news for a single named person, but the description never states when to prefer it over club_news, latest_news, or search_news, nor any exclusion conditions. Minimum-viable guidance.

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