get_prematch_news_for_upcoming

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

No annotations provided, so the description carries full burden. It indicates a read operation ('Get') but does not mention side effects, auth requirements, rate limits, or data freshness. The minimal description lacks behavioral detail for a tool with no annotation support.

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?

Single sentence, no filler, front-loaded with the core action. Highly efficient and to the point.

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 news retrieval tool with 6 parameters and no output schema, the description is adequate but leaves gaps. It does not explain the content format of news items, pagination behavior, or how parameters affect results within the subscription context.

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 all parameters are described in the schema. However, the tool description adds no additional meaning or domain-specific context for parameters like include, select, filters. It meets the baseline but does not enhance understanding beyond the schema.

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?

Description states 'Get pre-match news for upcoming fixtures within your subscription', clearly indicating verb (get), resource (pre-match news), and scope (upcoming fixtures, subscription). The 'upcoming' qualifier distinguishes from other get_prematch_news variants, but could be more explicit about the differentiation.

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?

No explicit guidance on when to use this tool vs alternatives like get_prematch_news or get_prematch_news_by_season_id. The mention of 'within your subscription' hints at context but does not provide exclusions or comparative advice, leaving the agent without clear selection criteria.

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