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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds context the annotations cannot: the required scope (neural:ask), an explicit risk classification of 'read', a statement of no side effects, and the current authorization state. That is meaningful disclosure beyond the structured fields, though it says nothing about freshness/caching behavior.

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 content list is front-loaded and the operational metadata (scope, risk, effects, availability) is compactly appended. Nothing is wasted, though the two-part structure mixing capability description with a deployment availability flag is slightly awkward. Appropriately sized for a single-parameter read tool.

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 carries the burden of indicating what comes back, and the parenthetical list of insight categories does that reasonably well. Combined with the read-only annotations and the availability warning, an agent has enough to decide whether to attempt the call. The one clear gap is the undocumented 'fresh' flag.

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 there is one parameter, 'fresh' (boolean, default false), whose purpose is never explained in the description. Presumably it forces a recomputation rather than returning cached insights, but an agent must guess. The description does not compensate for the coverage gap at all.

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 the concrete payload the tool returns (alerts, tips, forecasts and suggested actions) and grounds it with four tangible example categories (inconsistent stays, dirty properties with arrival, outstanding balance, forecast occupancy). That gives an agent a clear picture of the resource. It does not, however, distinguish this tool from similar siblings like get_daily_briefing, identify_opportunities or ask_neural, which is the missing point for a 5.

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 'INDISPONÍVEL nesta autorização' note is a genuinely useful negative signal — it tells the agent the tool cannot be called under the current scope, which is stronger than nothing. But there is no explicit positive guidance on when to prefer get_insights over ask_neural or identify_opportunities, and no exclusions or prerequisites beyond the availability flag. Usage is implied rather than specified.

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