x402node_time_timezone-convert

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

No annotations are provided, so the description bears full burden. It mentions conversion and IANA timezones but does not disclose any behavioral traits such as whether the operation is safe/mutating, authentication requirements, rate limits, or what happens if inputs are invalid. This is insufficient for a tool with zero annotation coverage.

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 short, but the first sentence is a keyword-stuffed list (redundant phrases like 'world clock' and 'international time'). The price note is irrelevant but does not detract much. It is reasonably concise for the information conveyed.

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?

The tool has 3 optional parameters and no output schema. The description explains the core function but does not describe the output format (e.g., datetime string, object) or default behavior for missing parameters (though schema implies defaults). It is adequate for a simple tool but could be more complete.

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%, and each parameter has a description in the schema. The description adds example timezone strings and the phrase 'any IANA timezone,' which provides context but does not significantly extend meaning beyond the schema. Baseline 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 it is a timezone converter, specifies converting between IANA timezones, and lists common abbreviations (UTC, PST, etc.). It distinguishes itself from sibling time tools like x402node_time_business-days and x402node_time_duration by focusing on timezone conversion.

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 indicates the tool converts datetime between any two IANA timezones but does not explicitly tell when to use it versus alternatives or mention any prerequisites or exclusions. The context of many siblings suggests a need for clearer guidance, but the basic usage is implied.

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