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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds only that pagination is supported, and it omits the third pagination mechanism (pageToken) entirely, which is a notable gap for a list tool.

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?

Two tight sentences, front-loaded with the purpose followed by the pagination note. No filler, though the pagination sentence mostly restates what the schema already shows.

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 simple read-only list tool with annotations covering safety, the description is adequate but thin: it gives no sense of the returned event shape, no guidance on choosing between limit/offset and pageToken, and no note on whether offset and pageToken are mutually exclusive.

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 must carry parameter meaning. It names limit and offset only as pagination controls without semantics (defaults, interplay, max 50 / max 10000) and says nothing about pageToken, leaving one of three parameters completely unexplained.

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 (elenca) and resource (eventi ai quali l'utente risulta registrato), clearly scoping to the current user's registrations. This distinguishes it implicitly from events.list, but no sibling is named 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 user-scoped framing implies when to use it versus events.list, but there is no explicit when-to-use/when-not statement and no mention of the adjacent alternatives like events.get_my_ticket or events.list_my_tickets, all of which are siblings an agent must choose between.

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