TDQS

B3.1/5.0

Behavior3/5

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

Annotations already provide readOnly, idempotent, and non-destructive hints. The description adds value beyond them with the ~5km approximation and the 5¢ per-call cost, but it does not disclose response behavior, edge cases, or any additional operational constraints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is exceptionally concise: two short sentences, with purpose and scope first and pricing separated into its own line. Every element earns its place with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter read-only endpoint, it covers the returned content and cost adequately. However, the unexplained gnaf_id parameter and lack of any input-format guidance leave a meaningful gap that the agent must infer.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The sole parameter, gnaf_id, has 0% schema description coverage, and the description only obliquely refers to 'the property' without explicitly explaining what gnaf_id is or its expected format. The description does not compensate for the missing schema detail.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear resource (schools near a property) with scope (~5km) and included data (rank, student counts). It is easily distinguishable from siblings like properties_schools_all and properties_schools_ranking, though it lacks an explicit verb.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to choose this tool over related siblings such as properties_schools_all, properties_schools_ranking, or suburbs_schools_nearby. There are no exclusions, prerequisites, or alternative routing cues.

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