TDQS

B3.2/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely new context by disclosing a per-call price of 15¢, which matters for an agent deciding between this and free/broader siblings, and by enumerating exactly which hazard flags are counted.

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?

Two sentences, no waste, with the enumerated hazard list up front and the cost disclosed last. The bolded price line is slightly stylistically intrusive but carries real decision value.

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 read-only aggregate with no output schema, the description should say more about returns: "counts and shares" implies numerators and percentages, but it doesn't state the shape (per-hazard object?), the denominator, or whether missing hazards are zero or absent. The hazard coverage and cost are well handled.

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 single parameter suburb_name has 0% schema description coverage, so the description must compensate and does not: it never mentions the parameter, its expected format (name vs. postcode vs. ID), or whether matching is exact. Only the possessive "the suburb's properties" loosely implies a suburb identifier.

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 verb (counts and shares) and a precise resource (the suburb's properties flagged with six named hazard categories). It does not name a sibling to contrast with, e.g. suburbs_risks_bushfire (single-hazard) or properties_risks_all (property-level), so the suburb-aggregate-vs-property split must be inferred from the name.

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 explicit when-to-use guidance and no exclusion of alternatives. An agent gets no signal about why it should pick this over suburbs_risks_counts, suburbs_risks_all, or the individual suburbs_risks_bushfire / _flood tools that appear as siblings.

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