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

Annotations already declare readOnly, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description adds genuine value beyond them: the declared risk class, 'Efeitos: Nenhum', and the important caveat that connections:manage scope may not be granted, which tells the agent the call can be unavailable. It does not explain what an unavailable call returns, keeping it short of a 5.

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 is dense but every clause earns its place by naming a distinct facet of the status payload. The one structural weakness is that the most operationally critical fact — that the tool is UNAVAILABLE under this authorization — is buried at the very end after scope/risk boilerplate rather than front-loaded.

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 return-value burden and does so well by enumerating the fields an agent will receive. The remaining gap is behavioral: it does not say what happens when the scope is missing (error vs. degraded payload), which matters given the explicit unavailability warning.

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?

The tool takes zero parameters and the schema is empty, so there is no parameter semantics to explain; baseline 4 applies. The description correctly implies a parameterless status snapshot.

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 a specific resource state (integration status) and enumerates the exact facets checked: paired browsers with online/offline state, Airbnb-linked properties, last sync, pending requests, and the next step plus who owns it. That enumeration is distinctive enough that an agent can distinguish it from generic status siblings like get_onboarding_status, though 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?

Usage is implied by the content ('verified state' plus 'next step needed'), but there is no explicit when-to-use versus alternatives such as list_extension_devices or get_onboarding_status. The 'INDISPONÍVEL nesta autorização' note signals a failure condition but not a selection rule, so guidance is only inferred.

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