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

No annotations are provided, so the description carries the disclosure burden. The verb 'get' implies a read-only operation, and the sole operation value 'get_date_time' reinforces that. However, it does not mention timezone, format, or return-value details, which are useful behavioral traits for a tool with no output schema.

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

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

The description is extremely short with no filler or redundant phrases. It is front-loaded, though the phrase 'time date' could be worded more clearly as 'date/time'.

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

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

For a simple one-operation tool, the description plus fully covered schema is sufficient to invoke the tool correctly. However, because there is no output schema, a brief note about the returned date/time format or timezone would improve completeness.

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

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

Schema description coverage is 100%, and the operation parameter is fully documented with an enum and descriptive text. The tool description adds no extra parameter meaning beyond the schema, so the baseline score of 3 is appropriate.

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

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

The description clearly states a get operation on an OS time/date resource, and the sibling tools are all Dooray-related, so this tool is easy to distinguish. The phrasing 'os time date' is slightly awkward, but the intent is unambiguous.

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

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

Usage is implied by the stated purpose: use this tool to retrieve the OS date/time. There is no explicit when-to-use guidance or exclusions, but the sibling set is unrelated, so the alternative-selection risk is low.

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