TDQS

D1.6/5.0
Behavior1/5

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

No annotations are provided, and the description discloses no behavioral traits beyond the bare output. It also fails to explain why the input schema contains four seemingly unrelated parameters (url, host, json, zone) that have no obvious connection to a UTC timestamp.

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

Conciseness3/5

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

The description is short and contains no filler words, but it is also extremely sparse. It lacks any structural elements like examples, parameter explanations, or usage scenarios, so the conciseness is not accompanied by useful structure.

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?

With four optional parameters of unclear relevance, no output schema, and no annotations, the description is severely incomplete. An agent cannot determine what arguments to pass, what the response looks like, or how this tool relates to the sibling time-related tools.

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?

Although the schema provides 100% description coverage, the parameters themselves are irrelevant to the stated purpose of returning a UTC timestamp. The description adds no clarification about what these parameters do or why they exist, leaving the agent with a confusing and incongruent parameter list.

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

Purpose2/5

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

The description 'Current UTC timestamp' is essentially a restatement of the tool name 'utc-time' with no verb or behavioral detail. It gives minimal information about what is returned, and it does nothing to differentiate this tool from siblings like 'timezone' or 'iana-zones'.

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?

The description provides no guidance on when to use this tool versus alternatives. Sibling tools such as 'timezone' and 'iana-zones' are completely unaddressed, leaving an agent to guess which tool is appropriate.

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