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

No annotations are provided, so the description carries the full behavioral burden. It does disclose a meaningful trait, the €16.70 price, which helps an agent understand this is a paid operation. Beyond that it says nothing about permissions, whether the operation is read-only or stateful, expected latency, or what the result contains.

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 text is short and front-loads the resource name and required input. However, it wastes space on an internal service ID ('689cb8972d09c0a9bcb946f5') that is meaningless to an agent, and the pricing/required lines are formatted as raw metadata rather than prose guidance.

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 paid document-generation tool with four parameters, no annotations, no output schema, and 0% parameter documentation, the description is far too thin. An agent cannot determine ordering requirements, delivery behavior, or what is returned, leaving critical gaps for correct invocation.

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%, so the description must compensate but largely does not. It notes taxCode is required, yet that fact is already encoded in the schema's required array, adding no new meaning. The other three parameters (phone, shippingAddress, shipmentRecipient) are entirely undocumented in both schema and description, leaving their role unclear.

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 names the resource ('Certificato Storico') and its category ('[Camerali]'), which conveys a specific document type. However, it reads largely as a restatement of the tool name and gives no functional explanation of what a historical certificate contains or how it differs from siblings like docuengine_certificato_di_iscrizione or docuengine_certificato_artigiano. An agent must still infer the actual purpose from the name alone.

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?

There is no indication of when to choose this tool over the many sibling certificato/visura tools, nor any prerequisites or exclusions. The only routing hint is the '[Camerali]' tag and the price, which do not tell an agent when this specific certificate is the right choice.

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