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 material trait – the operation is billable at €3.90 – which is genuinely useful. But it says nothing about permissions, auth, what the report contains, or how results are returned/delivered.

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?

It is short and front-loads the service line, but the internal service ID (680a53e1...) is noise for an agent, and the price/required lines duplicate structured data. Compact yet not maximally information-dense.

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?

With no annotations, no output schema, and a dense sibling family, the description should explain the report's content and return mechanism. It provides only a name, an opaque ID, a price, and a parameter restatement – insufficient for an agent to invoke this confidently.

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 for three undocumented parameters. It merely restates the required parameter names (name, surname, taxCode), which duplicates the schema's 'required' list without adding meaning – e.g., taxCode expected format, whether name must match taxCode, or case sensitivity.

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 a specific resource type ('Eventi Negativi Persona') and implicitly distinguishes itself from the azienda sibling via the 'Persona' qualifier. However, it never states a verb describing what the tool actually does (retrieve/download a negative-events report), and the Italian name may not convey meaning to an agent. Purpose is inferable but not explicit.

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 guidance on when to use this tool versus alternatives. Given 60+ siblings including docuengine_eventi_negativi_azienda and various protesti/pregiudizievoli tools, the absence of any routing or when-not-to-use context is a real gap.

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