TDQS

D1.3/5.0
Behavior1/5

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

With no annotations, the description must disclose behavioral traits, but it only says 'Current UTC timestamp.' It fails to mention that it might validate JSON, normalize URLs, or use timezone parameters, leaving the agent unaware of side effects or the actual operation.

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

Conciseness2/5

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

The description is a single short sentence, which is concise but so under-specified that it fails to convey necessary information. There is no structure or elaboration, making it more a placeholder than a usable description.

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

Completeness1/5

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

The tool has four unrelated parameters and no output schema. The description does not explain the return format, how parameters affect the result, or any operational context. It is severely incomplete for an agent to call the tool correctly.

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?

While schema description coverage is 100%, the description does not link the parameters to the tool's function. The parameters (url, host, json, zone) seem irrelevant to a timestamp tool, and the description provides no explanation of how they are used, so it adds little beyond the schema's own descriptions.

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

Purpose1/5

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

The description states 'Current UTC timestamp,' but the input schema requires parameters like url, host, json, and zone, which are unrelated to returning a timestamp. This mismatch makes the purpose misleading—an agent cannot infer what the tool actually does with these inputs.

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

Usage Guidelines1/5

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

No guidance is provided on when to use this tool versus alternatives like timezone or iana-zones. The description gives no context, prerequisites, or exclusions.

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