Property · Mesh blocks — 1 km buffer stats

properties_context_mesh_blocks
Read-onlyIdempotent

Mesh-block polygons within 1 km of the property (GeoJSON), each with avg annual growth, investor counts, modal street and median sold price.

Price: 30¢ per call.

Input Schema

NameRequiredDescriptionDefault
geojsonNoWhen false, geometry is dropped — every Feature keeps its per-mesh-block stats but its `geometry` is null. Use it for the stats surface without the polygons (default true — response unchanged).

TDQS

B3.3/5.0
Behavior4/5

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

Annotations already establish read-only, idempotent, and non-destructive behavior, so the description does not need to repeat that. It adds useful behavioral context beyond annotations: the 30¢ per-call cost, the GeoJSON output format, and the 1 km buffer scope with per-mesh-block stats. It does not contradict any annotation.

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 two dense sentences with no filler. The primary output and its stats are front-loaded, and the price is cleanly separated at the end. Every sentence earns its place.

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 two-parameter read-only tool, the description covers the output format, scope, and cost, and lists the included stats. However, the required gnaf_id remains undocumented, and there is no nod to when this fits among the many related property-context siblings. With no output schema, slightly more structural or usage context would be needed to be fully self-contained.

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?

Schema description coverage is only 50%: geojson is well documented in the schema, but the required gnaf_id has no schema description and the description does not explain its format or role beyond the word 'property'. The description adds essentially no parameter meaning beyond what the schema already provides for geojson.

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 the resource and scope precisely: GeoJSON mesh-block polygons within a 1 km buffer of the property, with the accompanying per-block statistics. This is enough to distinguish it from related shape/stat tools such as suburbs_shapes_mesh_blocks and mbs_list. It lacks an explicit verb like 'returns' or 'lists', but the deliverable is clear.

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?

There is no guidance on when to use this tool versus the many nearby sibling tools, such as properties_context_nearby_for_sale, properties_surroundings_properties, or suburbs_shapes_mesh_blocks. The only operational note is the price, which does not help an agent choose among alternatives.

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