convert_gregorian_to_hijri

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

With no annotations, the description should disclose behavioral traits. However, it only states the conversion without mentioning whether the operation is read-only, what happens with invalid dates, or any limitations. The agent is left uninformed about error behavior or output format.

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 a single sentence, concise and front-loaded. However, it is too brief to be fully helpful. Every word earns its place, but additional essential context is missing, making it borderline under-specified.

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 simplicity of the tool (3 integer params, no output schema), the description should at least mention the output format or provide a usage example. Without annotations, the description is incomplete for an agent to reliably use the tool without prior knowledge.

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 description coverage is 0%, meaning the description does not elaborate on the parameters. It simply shows names and types. There is no explanation of valid ranges (e.g., month 1-12, day 1-31) or the date format for Gregorian input. The description adds no value beyond the schema.

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's purpose with a specific verb ('Convert') and resource ('Gregorian calendar date to its Hijri equivalent'). It is distinct from the sibling tool 'convert_hijri_to_gregorian' which does the reverse 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?

No guidance is provided on when to use this tool versus alternatives such as 'convert_hijri_to_gregorian' or 'get_hijri_date'. There is no mention of prerequisites, date validation, or typical use cases.

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