calculate_timezone_convert

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

No annotations provided, so the description carries the full burden. It clearly states the tool accounting for date rollover and returning local time with date offset. No side effects or limitations are missing.

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 two sentences plus a brief note, all front-loaded with core purpose. No unnecessary words; each sentence contributes meaningfully.

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 the output schema, the description adequately describes return values as 'local time and date offset'. However, it could better differentiate from the similar sibling 'calculate_timezone_offset'.

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 coverage is 100% with descriptions for each parameter. The description simply lists the parameters without adding new semantics, meeting the baseline but providing no extra value.

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 converts a time between two UTC offsets with date rollover handling, distinguishing it from a simple offset calculation. The explicit mention of 'international meetings' provides context.

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 suggests using for 'international meetings' but does not explicitly compare to the sibling tool 'calculate_timezone_offset' or state when not to use it. The reference to 'list_bundles' is a weak alternative guide.

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