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 disloses that the tool returns an enumeration and that each item includes the date of the last lervation. The verb 'Elenco' implies a read-only listing, and no side effects or permissions need warning for a zero-parameter lookup.

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?

One sentence with no filler, front-loading the main content and adding the freshness attribute compactly. Every word earns its place.

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 listing tool, the description is nearly complete: it states what is listed and the associated date. It could be slightly stronger by explicitly saying the result is read-only or by hinting at the output shape, but nothing essential is missing.

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 no parameters, so the input schema already fully describes how to invoke it. The description correctly avoids adding parameter details; baseline 4 applies.

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 and resource: it lists the borse merci and price sources covered by BorsaBovini, adding the freshness date as the distinguishing feature. This is clearly different from siblings like prezzi_bovini or annunci_bacheca.

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 makes the tool's purpose obvious, but it does not explicitly indicate when to use it or which sibling to prefer. An agent must infer that this tool is for checking which markets/sources are available and how fresh they are before querying prices.

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