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

No annotations are provided, so the description carries the full burden. It does disclose the data source (Wikidata public data), which reasonably implies a read-only, unauthenticated lookup and explains why results may cover arbitrary games, but it says nothing about latency, rate limits, or what happens when a title is not found.

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 also enumerates the returned fields. No wasted words, though the enumerated field list could be read as pre-empting output documentation.

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 annotations and no output schema, the description usefully lists the returned data (release date, platforms, developer, website, YouTube) which compensates for the missing output schema. It remains incomplete on parameter semantics and on its relationship to sibling tools.

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 0% and the single parameter is the cryptic name 'q'. The description's phrasing about looking up 'any game' weakly implies q is a game name, but it never clarifies whether q accepts a title string, a Wikidata Q-ID, or both — a meaningful gap for a lookup tool.

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 (look up) and resource (any game) and identifies the data source (Wikidata public data), which distinguishes it somewhat from local-database siblings like get_game and list_games. However, it never names those siblings explicitly, so an agent must infer which tool is appropriate.

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 when-to-use guidance is given. The phrase 'any game' hints that this is for arbitrary titles outside the curated catalog, but the description never states when to prefer this over get_game or list_games, nor any prerequisites.

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