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

With no annotations provided, the description bears the full burden of behavioral disclosure. It only states a high-level transformation ('Free-text → Wikidata entities') without revealing query syntax, result format, rate limits, pagination, or read-only nature. This leaves significant operational uncertainty for an agent.

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 highly concise and front-loaded, delivering the key function in a single compact phrase. Every word contributes meaning, and there is no filler or redundancy. It could be longer to add context, but as written it avoids unnecessary verbosity.

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 single-parameter search tool, the description states the essential input behavior and general output direction. An output schema exists in the context signals, which may cover return details. Still, the description itself omits operational details like query size limits or result count, making it minimally adequate rather than fully 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 input schema is bare (just a 'q' string with a default), and schema description coverage is 0%. The description's 'Free-text' clarifies that 'q' is a natural-language query, adding meaning beyond the raw schema. However, it doesn't offer examples, length expectations, or language hints, so it only partially compensates for the missing schema descriptions.

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 a specific action ('Search') and target ('Wikidata entities'). The phrase 'Free-text → Wikidata entities' clearly communicates the input/output transformation, making the tool's core function unambiguous. However, it doesn't explicitly distinguish this from the sibling 'wikidata' tool or other wiki-related searches, though the name itself adds some 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 guidance is provided on when to use this tool versus alternatives like 'wikidata', 'nearbywiki', or 'wikipedia'. Given the large list of sibling tools, an agent has no way to know which one to select based on the description alone. Implied usage is limited to the 'search' phrasing, but 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.
