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

No annotations are provided, so the description carries the full burden. It identifies the tool as informational ('what it offers, how it is used'), which implies a read-only, side-effect-free operation. It does not detail the response format, whether the information is static, or any limitations, but for a simple info tool this is a reasonable level of disclosure.

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, well-structured sentence that front-loads the purpose ('what BorsaBovini.it offers and how to use it') followed by a compact list of covered topics. No filler or redundancy; every element contributes meaning.

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 zero-parameter, no-output-schema informational tool, the description gives enough context to understand its purpose and place among the siblings. It could be slightly more explicit that the output is likely a static text summary, but the scope is small and the description sufficiently covers it.

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?

The tool has zero parameters and the schema coverage is complete (100%), so the parameter semantics baseline is 4. There is nothing for the description to add about parameters, and it correctly omits any.

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 clearly states that this tool tells the user what BorsaBovini.it offers and how to use it, enumerating content areas (quotations, bulletin board, scan, transport, contacts). This distinguishes it from the sibling tools, which are specific feature-based tools, though the distinction is implicit rather than 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?

The description implies this is the general overview/help tool while the siblings cover specific functions, and the listed topics hint at those alternatives (quotazioni -> prezzi_bovini, bacheca -> annunci_bacheca, trasporti -> cerca_trasportatori). However, it never explicitly states when to use this tool versus a sibling, or when not to use it.

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