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

Annotations already establish readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description adds that results are paginated, which is useful beyond annotations, but says nothing about page size defaults, how pageToken and offset interact, or what the returned registration objects contain.

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 no filler, and the core action is front-loaded. It is efficient, but its brevity borders on under-specification given the undocumented parameters.

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?

There is no output schema, four parameters are entirely undescribed, and the description supplies none of that missing information. For a paginated listing tool where cursor/limit semantics matter, an agent still lacks enough to call it confidently.

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%, so the description bears full responsibility for explaining the four parameters, and it does not: neither eventId (required), limit/offset, nor pageToken is defined, nor is the mutual exclusivity or precedence of offset vs pageToken hinted at. 'Paginando' only vaguely gestures at the pagination parameters already visible in the schema.

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: lists event registrations by paginating participants of a managed event. The 'managed event' framing places it in the organizer namespace and distinguishes it from attendee-facing siblings like events.list_my_registrations, though it never names an alternative 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?

The phrase 'evento gestito' implies the organizer context and that the event must be one the caller manages, which is useful implicit scoping. However, there is no explicit when-to-use guidance against the many sibling tools (events.get, organizer.events.get_ticketing_summary, events.list_my_registrations), nor any stated preconditions.

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