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

With no annotations, the description carries the full burden, and it discloses only the price (€11.70) and the required parameter. It says nothing about whether this is synchronous or returns a request ID to poll (siblings like get_docuengine_request_status suggest an async pattern), what the returned document looks like, or any auth/permission requirements.

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 does not waste words, but the information it front-loads (ID, price, category) is metadata rather than task-relevant guidance. Compactness here reflects under-specification rather than disciplined concision.

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, multi-parameter, no-annotation, no-output-schema service in a dense sibling set, the description is far too thin: it omits the async/return behavior, the meaning of two optional parameters, and any routing logic. Only the cost and required field are covered.

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% across 3 parameters. The description names only taxCode (redundant with the schema's required list) and gives no meaning, format, or role for province or companyName, so it fails to compensate for the coverage gap.

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 essentially restates the tool name ('Fascicolo Storico Societa' Di Persone') plus an internal ID and a category tag '[Camerali]'. 'Direct tool for DocuEngine service' adds no semantic content, and no English gloss is given for what a 'Fascicolo Storico' actually retrieves. It does not distinguish itself from close siblings such as docuengine_fascicolo_societa_di_persone or docuengine_visura_camerale_storica_societa_di_persone.

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 when-to-use guidance, no prerequisites, and no mention of any alternative. The phrase 'Direct tool' hints at a contrast with some indirect/async path but never explains it, leaving the agent to infer selection among ~75 siblings unaided.

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