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

With no annotations supplied, the description carries the transparency burden and does well by listing the returned fields for each entity type. However, it does not mention read-only behavior explicitly, permission requirements, rate limits, or how missing or invalid ids are handled.

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 front-loaded with the core purpose and then supplies useful field and identifier details. It is dense but not wasteful; a slight structural improvement would be splitting the long parenthetical field list into shorter sentences.

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?

There is no output schema, so the description appropriately explains what a returned record contains for each entity type. It covers accepted identifiers and return content well, though it lacks not-found or error behavior, which would complete the picture for an agent.

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 schema already defines the single id parameter. The description adds value by naming the source of valid ids and providing examples such as 'lieu/riga-alberta-iela-4' and 'person/alvar-aalto', which clarify accepted identifier formats beyond the schema.

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 states a specific retrieval purpose: a full record of one entity from the architecture entity base. It distinguishes the three entity types and explicitly connects the id to search_baltic_finnish_architecture, which separates it from the sibling search tool.

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?

It clearly indicates the tool is for fetching a full record by an id returned from search_baltic_finnish_architecture or by Wikidata QID. It does not explicitly state when not to use it or name alternatives beyond the search tool, so it is strong but not fully explicit about usage boundaries.

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