TDQS

A4.1/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower, and the description still adds real value: a hard 500-pair result cap and an explicit per-call price. It stops short of saying how the summary is computed or what fields the pairs carry.

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 short sentences plus a price line, with the substantive content (growth + pairs + cap) front-loaded. The report-card framing is mildly redundant with the title but earns its place by locating the data in the product.

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

Completeness5/5

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

For a one-parameter read tool with full annotation coverage and no output schema, the description supplies what matters: what is returned, the result cap, and the cost. Missing detail (pair fields, suburb_name matching rules) is minor at this complexity.

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

Parameters5/5

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

Schema coverage is 0% for the single required parameter, but with only one self-describing parameter ('suburb_name' string) there is essentially no semantic ambiguity for the description to resolve. The description's silence on it costs little, so this sits at the top of the range.

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 names a specific metric and output shape: 'Realised resale growth — summary + individual buy/sell pairs (max 500)'. That is far more informative than the title and lets an agent distinguish it from price-series or recent-sales siblings by content, though it never names a sibling explicitly.

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 only implied through the report mapping ('Shown in the suburb report as the "Recent Repeat Sales" card'), which signals the reporting context but gives no when-to-use vs when-to-use-another guidance. The 15¢ per-call note is a useful cost caution but not routing guidance.

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