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

No annotations exist, so the description carries full burden. It states the tool searches for 'live or recent' matches but does not clarify if upcoming matches are excluded, if search results are paginated, or what happens on no results. Behavior details beyond positive returns are missing.

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?

Description contains two sentences with no wasted words. The first sentence presents the purpose and method, and the second lists returns. Information is front-loaded and clear.

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?

Given the tool has only one parameter and no output schema, the description adequately covers the main purpose and return values. However, it lacks details on result ordering, limits, or time scope (live vs recent). It is mostly complete for a simple search tool.

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?

The schema has 100% description coverage and the parameter description is identical to the text in the tool description. Therefore, the description adds no additional meaning beyond what the schema already provides, earning a baseline score of 3.

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 clearly states verb (search) and resource (football matches on Vublox) and lists return fields. However, it does not explicitly distinguish itself from sibling tools like get_live_matches or get_recent_matches, which could lead to confusion about when to use this search tool vs those specific retrieval tools.

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?

The description implies usage by giving examples of search terms, but it does not provide guidance on when to use this tool over alternatives (e.g., when to search versus using get_live_matches for all live matches). No exclusions or comparisons are mentioned.

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