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

No annotations provided, so description carries full burden. It discloses the response shape (JSON with files and attributes file_name, file_size, download_link, content, expire) and the dependency condition, which is useful. However, it omits auth requirements, rate limits, what happens if the condition is not met, and whether the download is destructive or read-only.

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 content is front-loaded with the triggering condition and then the response structure. Two short paragraphs, no filler, though the parameter descriptions are vague rather than concise.

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 two-parameter download tool with no annotations and no output schema, the description provides the response shape and the prerequisite condition. It still lacks error handling, authentication needs, and clear parameter sourcing, leaving gaps an agent might encounter.

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% with 2 required parameters (document_id, document_url). The description says both are 'the value id in return of a previous request', which is imprecise and confusing—document_url is described as an id, not a URL. No format, source, or distinction between the two parameters is clarified.

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?

States a specific verb (Download) and resource (document), and uniquely ties the action to the estado_richiesta value 'Dati disponibili' from get_italian_company_official_document. Distinguishes from sibling get_italian_company_official_document, though it could name other document siblings more explicitly.

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?

Gives a clear condition: use only when stato_richiesta equals 'Dati disponibili' from a prior get_italian_company_official_document call. No explicit when-not or alternatives, but the precondition is a strong routing signal.

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