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

Annotations already declare readOnlyHint=true, destructiveHint=false, and closed-world, so the safety profile is covered. The description adds no behavioral context beyond that — no mention of scope limits, auth requirements, or whether results include bookings across all sessions.

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, front-loaded sentence with no filler. Efficient, though the compressed list of returned fields (agenda, capacity, bookings) is slightly ambiguous rather than precise.

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 must convey what comes back; it gestures at agenda/capacity/bookings but not structure, ordering, or aggregation (e.g., per-session vs aggregate). For a read tool with a single param this is minimally adequate but leaves real gaps.

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?

Only one parameter (eventId) with 0% schema coverage, but the description's phrase 'di un evento gestito' implies the id selects a managed event, which partly compensates. It does not clarify format, expected values, or what 'managed' implies for access, so the schema gap is only marginally bridged.

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 names a verb ('Restituisce') and a resource set (agenda, capienza, prenotazioni sessione) scoped to a managed event, which suggests organizer view. However, it never clearly states this returns the sessions of an event nor distinguishes it from close siblings like organizer.events.get_dashboard, get_registrations, or get_ticketing_summary, all of which plausibly return overlapping data.

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 guidance on when to call this versus the many sibling tools that also surface event data (get_registrations, get_ticketing_summary, get_dashboard). No prerequisites or exclusions are stated, leaving selection entirely to inference.

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