get_area_stats

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

No annotations are present, so the description carries the full behavioral burden. It only says 'Get...', implying a read operation, but it does not disclose output format, how the address is resolved to a municipality, or any other behavioral characteristics. This is minimal transparency for a tool with no annotations.

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 a single, front-loaded sentence with no filler or redundant wording. Every part adds meaning, identifying both the data type and source.

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 tool with no output schema, no annotations, and an undocumented addressId parameter, the description is incomplete. It states what statistics are returned but not how to properly identify the municipality or what the result structure looks like, making it difficult for an agent to invoke correctly without additional context.

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 provides only the type and name 'addressId' with 0% description coverage, and the description never explains what addressId means or how it relates to municipality-level statistics. The agent must guess whether the ID comes from search_address, what format is expected, and how the municipality is derived.

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, resource, and granularity: 'Get municipality-level population, income and dwelling statistics from Danmarks Statistik.' This clearly distinguishes it from sibling tools that return buildings, parcels, valuations, or admin areas.

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?

The description implies when to use the tool: when municipality-level demographic, income, or dwelling statistics are needed. However, it gives no explicit guidance or exclusions relative to sibling tools like get_admin_areas or search_address, leaving the agent to infer the proper selection.

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