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 the useful scope constraint ('global English') and notes the feed is paginated by zero-based offset, but says nothing about page size, result count, or ordering/freshness beyond annotations.

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 compact sentence that front-loads the resource and appends the pagination note; every clause carries information and there is no filler.

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 simple one-param read feed with an output schema and clear annotations, the description is minimally sufficient. However, it omits page size and does not differentiate from the many sibling fotmob news feeds, leaving a meaningful selection gap for the agent.

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% and the single parameter's meaning (zero-based offset, default 0) is fully documented in the schema. The description only restates 'paginated by zero-based offset', adding no syntax or boundary detail beyond what structured data already provides, 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 names a specific verb+resource: a football-news feed scoped to 'global English'. It clearly identifies what the tool returns, but it never distinguishes itself from sibling news tools such as fotmob_news, fotmob_trending_news, or fotmob_team_news, so an agent cannot tell which feed to pick without opening schemas.

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 when-to-use guidance and no mention of alternatives, despite a dense cluster of sibling news endpoints. The phrase 'latest football-news feed' implies usage but gives no condition that selects this tool over fotmob_news or fotmob_trending_news.

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