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

Annotations are absent, so the description carries the full burden. It usefully discloses data provenance (identities verified against Wikidata), corpus size, and that results are ids for get_architecture_record, but it omits auth/permission needs, rate limits, result ordering, and pagination behavior beyond the k parameter. Moderate disclosure for a read search tool.

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?

Purpose is front-loaded, but the sentence is bloated with long enumerations of cities, buildings, and entity counts, plus a redundant French restatement at the end. Much of that catalogue detail aids discovery but could be trimmed without losing call-critical information.

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 seven optional parameters, 100% schema coverage, and no output schema, the description covers corpus scope, matching behavior, filter purpose, and id-to-record chaining well. It leaves ranking and result-shape behavior implicit, but for a search endpoint that is a minor gap.

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 100%, so the baseline is 3; the description adds value by specifying that q matches local, English, and French names plus architects, styles, periods, and descriptions, which is meaning beyond the schema's generic 'free text' wording. It also clarifies that filters are optional and may substitute for q.

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?

States a specific verb ('Search') and a clearly bounded resource (an architecture entity base covering the Baltic states and Finland), and names get_architecture_record as the follow-up for returned ids. It does not explicitly distinguish itself from the sibling search_corpus, which is the one remaining ambiguity, so it falls just short of a 5.

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?

Offers some in-context guidance ('Can be empty if filters are set' for q, 'Use this to compare cities' for era) and notes filters are optional. However, it never says when to prefer this tool over search_corpus or when not to use it, so the alternatives comparison is left to inference.

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