convert_time

Convert time values between different units like seconds, minutes, hours, days, weeks, and years. Enter a numerical value with source and target units to get the converted result.

Instructions

Convert time between different units: seconds, minutes, hours, days, weeks, years, etc. (Domain: conversions, Category: general)

Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool performs conversions but does not describe any behavioral traits such as error handling (e.g., invalid units), precision, rounding, or output format. For a tool with no annotations, this is a significant gap in transparency about how the tool behaves in practice.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded, consisting of a single sentence that directly states the tool's purpose. It avoids unnecessary details and wastes no words, making it easy to parse. However, the inclusion of domain and category in parentheses, while informative, slightly detracts from absolute minimalism.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (3 parameters, no annotations, no output schema), the description is incomplete. It lacks details on parameter constraints, behavioral traits, and output format, which are crucial for correct tool invocation. Without annotations or an output schema, the description does not provide enough context for reliable use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage, so the description must compensate. It lists example units (seconds, minutes, hours, etc.) which partially clarifies the 'from_unit' and 'to_unit' parameters, but does not specify allowed unit strings, case sensitivity, or constraints on the 'value' parameter. With 3 undocumented parameters, the description adds some meaning but is insufficient to fully explain parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: converting time between different units like seconds, minutes, hours, etc. It specifies the verb ('Convert') and resource ('time'), and includes a domain/category for context. However, it does not explicitly differentiate from sibling tools like convert_angle or convert_length, which serve similar conversion purposes but for different quantities.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It mentions the domain and category but does not specify any prerequisites, constraints, or scenarios where this tool is preferred over other conversion tools (e.g., convert_speed, convert_temperature). This lack of explicit usage context leaves the agent without clear direction.

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