TDQS

C2.7/5.0
Behavior2/5

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

With no annotations, the description carries the full transparency burden but only states the result. It does not disclose the timestamp format, confirm that parameters are ignored, or mention any behavior beyond 'current 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.

Conciseness4/5

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

The description is maximally concise and front-loaded; every word contributes. It loses points only because it omits minimal details needed for correct invocation, not because of redundancy.

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 simple-looking tool with four unexplained optional parameters and no output schema, the description is incomplete: it fails to specify the return format, the role of the parameters, or when to prefer sibling tools like 'timezone'.

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 documents each parameter, the descriptions like 'HTTPS URL to normalize or cite' and 'JSON text to validate' are unrelated to 'Current UTC timestamp'. The tool description adds no clarification, so an agent cannot tell how url, host, json, or zone relate to this tool's purpose.

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 'Current UTC timestamp' clearly conveys the output resource and the implied operation of retrieving the current UTC time. It does not use an explicit verb or contrast with the sibling 'timezone', so it stops short of full differentiation.

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 is given on when to use this tool rather than 'timezone' or 'iana-zones', nor whether the four optional input properties affect the result. The agent receives no context for choosing between utc-time and its siblings.

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