search_personer_folkeregisteret

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

No annotations are present, so the description must disclose behavioral traits itself. It only states the search criteria and fails to mention that this is a read-only operation, what response format to expect, or any pagination or authentication considerations. This is a significant gap for an API with 8 parameters.

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 that directly states the tool's purpose without filler or redundant explanation. It is concise and well-structured, making it easy to parse.

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?

Given the tool's moderate complexity (8 optional filters, no output schema, no annotations), the description is too sparse. It does not explain that the tool returns a list of matching persons, how filters combine, or any operational limits, leaving the agent without essential context for correct invocation.

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?

All 8 parameters have descriptions in the schema (100% coverage). The description merely lists some criteria ('gender, birth date range, municipality, citizenship, or civil status') that are already documented, adding no new meaning about parameter combinations, constraints, or defaults.

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 clearly states the action ('Search'), the resource ('persons in the Population Register'), and lists specific filter criteria. It distinguishes from siblings like get_person_folkeregisteret by indicating a multi-criteria search rather than a single-person lookup.

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 usage through 'Search for persons by criteria' but gives no explicit guidance on when to use this tool versus alternatives like get_person_folkeregisteret or get_folkeregisteret_hendelser. No exclusions or alternative mentions are provided.

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