Query UK Biobank (Stub)

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

No annotations provided, so description carries full burden. It mentions 'requires application,' indicating an access barrier, but fails to disclose other behaviors such as expected response format, rate limits, or whether it supports complex queries. Significant gaps for a tool with zero 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?

Extremely concise but under-specified. The single sentence does not earn its place as it lacks critical details needed for correct usage. Conciseness is positive but here it sacrifices completeness.

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 has an output schema (not provided in input) and likely complex access controls, the description is incomplete. It does not explain what happens after query execution, how to handle access, or any return value semantics. Sibling tools with more detailed descriptions set a higher bar.

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% (1 parameter fully described). Baseline 3 applies. The description adds no additional meaning beyond the schema field 'UK Biobank query'—no hints on query syntax or required structure.

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?

Description states it queries UK Biobank large-scale biomedical data, which is the main purpose. However, it is vague about the type of queries (e.g., API, SQL) and does not distinguish from sibling tools similarly querying other databases. The phrase 'requires application' hints at access but does not clarify scope.

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 on when to use this tool versus siblings like query_drugbank or search_clinical_trials. The description implies an access requirement but does not specify prerequisites or context for use.

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