TDQS

A4.2/5.0

Behavior4/5

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

It goes beyond the structural annotations by detailing the output behavior: 'A terminal response includes the bounded result and source_anchor for direct consumption.' This clarifies the nature of the response and how it should be handled.

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

Conciseness5/5

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

The text is extremely dense and efficient. Every sentence adds specific, non-redundant value to the tool's definition, making it a masterclass in front-loading information.

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?

The description is highly complete regarding output behavior and input nature. It clearly defines the purpose of the polling action. It stops short of specifying expected latency or time boundaries for the poll, which would be an extra point, but is very strong for a concise tool.

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

Parameters4/5

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

Given that schema description coverage is 0%, the description provides essential semantic meaning by defining 'task_ref' as 'one opaque task reference.' This is critical for agents to understand what kind of identifier is required.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a precise verb ('Poll') and identifies the specific resource being interacted with ('opaque task reference'). It is highly specific and distinct in its functional purpose.

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 provides a vital usage constraint: 'never rerun the original query page 1.' This prevents misuse. However, it does not provide explicit guidance on when to use this specific tool versus a list or discovery tool among the siblings.

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