get_current_time

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It indicates a read operation ('조회한다'), which implies safety, but does not add extra context such as error behavior, system-clock dependence, or rate limits. For a simple read tool this is acceptable but not rich.

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 concise, consisting of one clear purpose sentence and a brief parameter explanation. It is front-loaded with the action and resource, and every word earns its place. No redundant or filler content.

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?

With only one optional parameter and an output schema present, the description covers the essential context. It clearly explains the main function and the only argument. It could improve by mentioning what happens if timezone is omitted, but the schema's default already covers that. Overall, it's complete for a tool of this simplicity.

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 0%, so the description must compensate. It does so by defining the 'timezone' parameter as an IANA timezone name with a default of Asia/Seoul, which adds meaningful semantic detail beyond the schema's generic 'string' type. This is sufficient for the single parameter.

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 the tool's function: to retrieve the current time in a specified timezone. It uses a specific verb, '조회한다' (retrieves), and a specific resource, '현재 시각' (current time). This distinguishes it from sibling tools like convert_time (which converts times) and find_timezone (which finds timezones).

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?

The description implies usage for getting the current time in a timezone, but does not explicitly contrast it with alternatives. No 'use this when' or 'instead of' guidance is provided, unlike the high-caliber example that names an alternative tool. The context is clear but lacks explicit exclusions.

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