Gregorian to Hebrew date

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

With no annotations, the description carries the full disclosure burden. It does reveal the output shape (Hebrew calendar plus traditional letter form), which is genuinely useful. However, it omits meaningful behavioral traits for a calendar converter: whether the result reflects the Hebrew day starting at sunset, how timezone is handled, and whether the conversion range is bounded.

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?

A single sentence, front-loaded with the core action, followed by the output detail and a short example. Nothing is redundant or padded.

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?

For a one-parameter, no-output-schema utility, the description covers input format and output content adequately. The remaining gap is the absence of any caveat about sunsets/timezones or supported date ranges, which matters for a calendar conversion tool.

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% and the sole parameter is described only by a regex pattern, so the prose must compensate. It does: the parameter is identified as a Gregorian date in YYYY-MM-DD form, which is the key semantic an agent needs for this one-parameter tool.

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 states a specific verb and resource (convert a Gregorian date to the Hebrew calendar) and adds a concrete output detail — the traditional Hebrew letter form with a worked example. No sibling tool (phone, ID, VAT, IBAN, numerals) does date conversion, so an agent can route to it unambiguously.

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?

Usage is only implied: the tool is a single-purpose converter, so when to call it is fairly self-evident from the purpose statement. There is no explicit statement of when NOT to use it, no mention of a reverse-direction counterpart, and no note on acceptable date ranges.

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