get_timezone_info

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

No annotations provided, so description carries full burden. It mentions return of current time and offset, but doesn't discuss error handling, behavior on invalid timezone names, or any other side effects. Adequate but not comprehensive.

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?

Single sentence, efficient, no redundant content. Could be slightly more informative without increasing length, but remains appropriately concise.

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?

Given a single parameter and no output schema, the description fully explains purpose and return content. However, specifying output format (e.g., JSON fields) would enhance completeness. Overall, sufficient for a simple tool.

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?

With 100% schema coverage and a single parameter already described, the description adds minimal value beyond restating 'including current time and UTC offset'. It does not elaborate on parameter format or constraints.

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 gets information about a specific timezone including current time and UTC offset. It uses a specific verb 'Get' and resource 'timezone info', distinguishing it from sibling tools like convert_time or get_current_datetime.

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 when timezone info is needed, but lacks explicit when-to-use, when-not-to-use, or references to alternatives. No guidance on when to prefer this over sibling tools like convert_time.

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