check_vehicle_access

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive. The description adds a little context ('now Europe/Rome', 'current catalog'), but it does not explain that the request is evaluated, how the result is conveyed, or what 'nessun divieto' implies for the caller.

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?

The text is short, but it is under-specified rather than concise. It front-loads a status-like assertion instead of a purpose, so the single sentence does not earn its place.

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?

This tool takes a required nested request with multiple semantic fields, yet the description gives no usable context for constructing or validating that request. An agent cannot infer when to call it, what inputs matter, or how to interpret the result.

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%, and the sole parameter `request` embeds a complex AccessRequest. The phrase 'Profilo/perimetro dichiarati' gives only a vague hint and does not explain `vehicle`, `area`, `at`, or `inside_area_confirmed_by_user`.

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 reports a state ('nessun divieto abilito') rather than stating what the tool does. It never says it checks vehicle access against a request, so it could be mistaken for an output or catalog status message.

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?

No guidance is given for when to use this tool versus the siblings query_movein_allowance, get_active_smog_level, or get_daily_costs. There are no conditions, exclusions, or alternative selection criteria.

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