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

Annotations already declare this is a read-only, non-open-world operation, so the safety profile is covered. The description adds that results carry a date and time slot, which is useful return-shape context, but says nothing about ordering, filtering, or whether past events are included.

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 compact sentence with the key information front-loaded. No filler, though the trailing parenthetical is slightly informal and the ellipsis makes the enumeration of event types open-ended.

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 output schema, the description carries the burden of describing return content and does so adequately (date and time slot for each special event). For a parameterless listing tool this is close to sufficient, missing only ordering or scope details such as whether only upcoming events are returned.

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 takes zero parameters, so the baseline is 4. There is nothing for the description to disambiguate, and it correctly does not invent parameter behavior.

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 states a specific resource (giornate speciali / special events) with examples of what they are (screening, consulenze) and what data accompanies them (date and time slot). It implicitly reads as a listing operation, though it never uses an explicit verb and does not explicitly distinguish itself from the sibling get_special_event_availability.

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 statement of when to use this tool versus alternatives such as get_special_event_availability, list_services, or the booking tools. The usage context is only inferable from the noun phrase 'in programma'.

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