A3.7/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely new behavioural context: a hard 200 m radius bound, the per-property payload fields, and an explicit cost of 15¢ per call, which matters for an agent deciding whether to loop this across many properties. It omits any result cap or pagination behaviour for dense areas.

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

Conciseness4/5

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

Three short lines with the scope statement front-loaded and the cost signal isolated at the end, which is easy to scan. The first sentence partly restates the title ('Meet the neighbours'), a minor redundancy, but no sentence is filler.

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

Completeness4/5

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

There is no output schema, and the description compensates by naming the returned fields (lat/lng, mesh block) and the geographic scope. For a single-parameter read tool with full annotation coverage, that is close to sufficient; only the volume of results in dense areas remains unspecified.

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

Parameters3/5

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

Schema description coverage is 0%, so the single gnaf_id parameter is undocumented in the schema itself. The description only obliquely conveys meaning via 'the subject', implying gnaf_id is the subject property identifier, but it never states the format or that it must be a resolved GNAF ID rather than an address string.

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?

States a specific resource and scope: 'Every GNAF property within 200 m of the subject, with lat/lng and mesh block.' That is far more concrete than the title alone and implies a distinct dataset from siblings such as properties_neighbours or properties_surroundings_parcels. It never names those alternatives explicitly, so an agent must infer the boundary itself.

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

Usage Guidelines3/5

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

Usage is implied by 'Shown in the property report as the Meet the neighbours map pins in the Overview section', which tells the agent this feeds a map visualisation, plus the fixed 200 m radius constraint. There is no explicit when-to-use versus when-to-prefer properties_neighbours, properties_surroundings_parcels, or properties_context_mesh_blocks, and no stated prerequisite that a valid gnaf_id must already be resolved.

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