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

Annotations declare readOnlyHint and idempotentHint, so the safety profile is covered structurally. The description adds the useful ordering trait (newest first) but says nothing about pagination, rate limits, or failure behavior; a 3 fits given annotations already carry the read-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?

Two tight sentences: source and ordering first, then the optional filter with its vocabulary. No filler, every clause carries information.

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 two-param read-only feed with no output schema, the description covers source, ordering, and filter vocabulary adequately. The only shortfall is not situating it relative to the four sibling news tools.

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% (baseline 3), and the description goes beyond the bare 'News type filter' schema text by translating each enum value (matbuot = press/quotes, natija = final match results, umumiy = general), which is real added meaning for an agent choosing a filter.

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?

Names a specific resource (football news from gol24.uz) with a clear scope and ordering (newest first). It does not differentiate itself from siblings like club_news, person_news, or search_news, so the agent must infer that this is the unfiltered/broad feed.

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?

Implies usage via 'Optionally filter by type', giving mild guidance on when to pass a filter. There is no statement of when to prefer this over search_news, club_news, or person_news, and no exclusions.

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