  2. First observed

TDQS

A3.6/5.0
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 useful behavior beyond that: a per-call price of 10¢ (cost control matters for agents) and the fact that results are bucketed and ordered nearest-first, which affects downstream handling.

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 sentences with no filler; the pricing note is clearly separated and the scope sentence is dense but readable. Slight weakness: the leading sentence about report placement is the least actionable information and is front-loaded ahead of the actual purpose.

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?

With no output schema, the description does helpfully signal result shape (bucketed, nearest-first) and the amenity categories. However it leaves the required gnaf_id unexplained, does not enumerate the full set of buckets, and gives no notion of response size or whether results are capped, which matters for a radius up to 5000m.

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 coverage is 50%: radius_m is fully documented in the schema (range and default), and the description only restates it as the search distance. The required gnaf_id is undocumented in both schema and description, so the description fails to compensate for the coverage gap; a 3 reflects the schema doing most of the work.

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 (curated amenities: supermarkets, green spaces, restaurants/cafes) and scope (within radius_m of the property, bucketed, nearest-first). The category list implicitly separates it from properties_schools_nearby and properties_transport_nearby, but it never names those siblings explicitly, so the differentiation is left to inference.

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?

The description gives context ('shown in the property report Lifestyle section') and cost, which implies but does not state when an agent should prefer it over nearby-tool alternatives. There is no when-not-to-use rule and no guidance on choosing a radius, so usage is only implied.

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