convert_time

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

With no annotations, the description carries the full burden of behavioral disclosure. It only gives a minimal function statement and argument formats, without mentioning edge cases, error handling, side effects, or the nature of the conversion (e.g., DST handling). It adds no behavioral insight beyond the obvious pure conversion.

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—a single sentence plus a compact Args list. Every element is necessary and informative, with no filler or redundancy.

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 is simple and has an output schema, so return details are not needed. The description adequately covers the core purpose and all parameters. However, it lacks any usage context or notes on potential pitfalls (e.g., invalid timezone, DST edge cases), which would make it more complete for robust agent use.

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?

The description explicitly explains each parameter: time with accepted formats (`YYYY-MM-DD HH:MM` or ISO 8601), and from_timezone/to_timezone as IANA timezones. This adds significant meaning over the bare schema titles (Time, To Timezone, From Timezone) and fully compensates for the 0% schema description coverage.

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 'Converts a time in one timezone to another timezone', specifying the verb (convert), resource (time), and the from/to timezone context. It unambiguously distinguishes from siblings like get_current_time, find_timezone, and weather tools.

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?

No guidance is provided on when to use this tool versus alternatives. It simply states what it does without mentioning scenarios, exclusions, or references to sibling tools like get_current_time or find_timezone.

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