TDQS

C2.9/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering safety. The description adds value by disclosing the output structure (summary + individual pairs) and the 500-pair limit, which are not in annotations. This provides useful behavioral context beyond 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.

Conciseness4/5

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

The description is a single, tightly packed sentence that conveys the core purpose and a key limitation (max 500). It is not verbose and earns its place, though it omits essential parameter context.

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

Completeness2/5

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

For a one-parameter tool with no output schema, the description is insufficient. It does not explain what the summary contains, what fields each pair has, or any error conditions. The agent cannot fully anticipate the response format or parameter requirements, especially given the many sibling market tools.

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

Parameters1/5

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

Schema coverage is 0% and the description does not mention the only parameter, suburb_name, at all. The agent gets no guidance on what this parameter represents, its format, or how to obtain it. The description entirely fails to compensate for the missing schema documentation.

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 clearly states it returns 'Realised resale growth' with a summary and individual buy/sell pairs, capped at 500. This is specific and distinguishes it from other market tools (e.g., price growth, sales summary) by focusing on repeat-sale realized growth. It lacks an explicit verb like 'get' but the intent 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?

No guidance on when to use this tool versus alternatives. It does not mention any distinguishing context, such as 'use for repeat-sale growth analysis' or exclude scenarios better served by other market tools. The agent is left to infer usage from the name and sibling list.

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