Read-onlyIdempotent

Shown in the property report as the 'Landslide risk' card in the Risks section.

Landslide-risk overlays within 1 km. Read on_property — a returned row means "found nearby", not "this property is at landslide risk".

Price: 3¢ per call.

  2. First observed

TDQS

B3.4/5.0
Behavior4/5

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

Beyond the readOnly/idempotent annotations, it discloses a genuinely valuable interpretive rule: a returned row means 'found nearby', not that the property itself is at risk. It also surfaces the per-call price and the 1 km buffer, which are behavioral facts an agent cannot infer from structured fields.

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

Conciseness3/5

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

Three short blocks with zero padding, but the report-card placement sentence leads while the actual behavior (1 km overlays) and the critical caveat come later. Reordering to put the operational sentence first would improve front-loading.

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?

For a read-only two-parameter lookup with no output schema, the description covers scope, the key interpretation rule, and cost. The only real omission is what gnaf_id must be, which is consistent across the whole properties_* family and thus recoverable from siblings.

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%: the geojson flag is well documented in the schema, but gnaf_id has no description anywhere. The description adds no parameter-level meaning at all, and the 'on_property' guidance refers to a return field rather than an input, so it does not compensate for the gap.

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 concrete resource and scope: landslide-risk overlays within 1 km, tied to the property report's 'Landslide risk' card. The sibling family (bushfire, flood, erosion, heritage, etc.) makes the hazard-specific scope obvious, so an agent can select it without opening the schema.

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 implies usage by naming where it surfaces in the property report, but never states when to prefer it over siblings such as properties_risks_all or the area-level suburbs_risks_slope. No explicit exclusions or alternative routing are given.

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