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

Annotations already establish the safe read-only, closed-world profile, so the description's added value is the QR-exclusion data constraint and the pagination note. However, it says pagination works 'con limit e offset' while the schema also exposes pageToken, which makes the behavioral picture incomplete and slightly misleading.

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 sentences, zero waste: purpose and QR constraint first, pagination behavior second. Nothing redundant and nothing buried.

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 the core is present, but with no output schema the description should sketch what a ticket record contains (event, seat, status, transfer state), and it should cover pageToken. As written an agent can call it, but must guess at result shape and the third parameter.

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 all parameter meaning, yet it only names limit and offset as 'pagination' without defaults, ranges, or interaction semantics, and omits pageToken entirely — leaving one of three parameters undocumented anywhere.

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 ('Elenca i biglietti') with scope qualifiers — tickets owned by or transferred to the user — and notes the QR is not exposed. This differentiates it from events.list and events.list_my_registrations by resource type, though it never names the siblings it is distinct from.

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 scope phrase 'posseduti o trasferiti all'utente' implies the usage context (personal ticket listing), but there is no explicit when-to-use/when-not guidance and no routing to the obvious alternative, events.get_my_ticket, for retrieving a single ticket (which is presumably where the QR lives).

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