TDQS

A4.4/5.0
Behavior4/5

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

Annotations already establish read-only, non-destructive, idempotent behavior. The description adds useful behavioral context beyond annotations by specifying that the tool waits, returns exactly one bounded payload, and disconnects after the event. It could say more about timeout behavior or payload contents, but it meaningfully supplements the annotation-only safety profile.

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 description is a single, efficient sentence that front-loads the key behavior: waiting, receiving one bounded payload, and disconnecting. Every phrase earns its place with no redundancy.

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 zero-parameter subscription tool with safety annotations and no output schema, the description covers the essential operational contract: one bounded event, then disconnect. The main omitted detail is the internal structure or meaning of the payload, but the tool name and sibling context indicate parity history data, so the gap is minor.

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?

There are zero parameters, so there is nothing for the description to explain beyond noting that no input is required. Baseline 4 is appropriate since schema coverage is complete and no semantic gaps exist.

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?

States a specific action and resource: wait for the next event from a fixed GraphQL subscription, return one bounded payload, then disconnect. This clearly distinguishes it from one-shot query siblings like unraid_v4371_query_parity_history and from other next-event subscriptions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly indicates the tool is a one-shot subscription consumer: wait for the next event, receive one payload, then disconnect. It does not explicitly name alternatives or exclusion conditions, but the fixed-subscription framing gives sufficient context for when to call it.

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