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

No annotations are provided, so the description carries the full burden. Disclosing the Wikidata source is useful context, but the description says nothing about matching/fuzzy behavior, what happens when no event is found, or rate limits. For a lookup tool with zero annotation coverage, this is a notable gap.

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 front-loaded sentence that efficiently conveys source, scope, and returned fields with no wasted words. Slightly dense but appropriately sized for the tool's simplicity.

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-parameter lookup with no output schema or annotations, the description covers what the tool does and what it returns. However, it omits any explanation of the 'q' input, which is the main thing an agent must supply, leaving the definition only marginally complete.

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 single parameter 'q' has no schema description (coverage 0%), and the description does not explain its format or whether it expects an event name, free-text query, or Wikidata Q-ID. With 0% coverage the description needed to compensate and does not.

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 gives a specific verb (查/look up) and resource (任何運動賽事/any sports event), plus the data source (Wikidata 公開資料) and the fields returned (日期、地點、項目、冠軍、官方網站). This clearly distinguishes what it does, though it does not explicitly name or contrast with siblings like get_sports_event or list_sports_events.

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, no prerequisites, and no mention of alternatives such as get_sports_event or list_sports_events. The agent is left to infer that this is the generic Wikidata-backed lookup without any routing criteria.

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