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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds the useful detail that the response includes teams, score, status, events, venue, and referee, but it does not extend behavioral context such as error handling, data freshness, or shape beyond the listed fields.

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?

The description is a single compact sentence fragment that front-loads the resource scope and then enumerates returned content. It is efficient and free of filler, though the fragmentary phrasing is less helpful than a complete clause would be.

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 and no annotations covering return content, the description does list the main fields returned, which is helpful. However, it does not explain the relationship to sibling match tools or provide enough context for an agent to confidently choose this over get_match_details or get_match_briefing.

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 each parameter is clearly documented in the input schema, including lang, sport, and match_id. The description adds no parameter-level meaning beyond the schema, 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 identifies the resource and lists the fields returned by a single-match lookup, but it does not explicitly distinguish this tool from siblings like get_match_details, get_match_briefing, or get_matches. It is clear enough to know it returns one match, but not why an agent should choose it over the closely named alternatives.

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 guidance on when to use this tool versus get_matches, get_match_details, or get_match_briefing. The required sport and match_id parameters imply it needs an existing match identifier, but the description never states prerequisites or exclusions.

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