auth_status

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

No annotations are provided, so the description carries the full burden. It discloses the extra behavior of 'verify=True' (making a minimal private call), which adds value. However, it does not describe potential return values, error behavior when the session is not configured, or any side effects, leaving gaps in transparency.

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 description is a single sentence that conveys both core purpose and a parameter behavior. It is front-loaded, information-dense, and contains no unnecessary words or repetition.

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?

Given the tool's simplicity, the description covers the core function and the parameter's effect, but the absence of an output schema means the description should ideally mention what the tool returns (e.g., a boolean status). It also lacks context on what 'session configured' means or what happens when verification fails, leaving the agent somewhat under-informed.

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 schema has one optional 'verify' parameter with no description (0% coverage). The description compensates by explaining that 'verify=True' triggers a minimal private call, giving meaningful semantic context beyond the bare boolean type. It does not fully elaborate on the default false behavior, but it adds key meaning.

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 uses a specific verb ('comprueba' = checks) and clearly identifies the resource ('si la sesion local esta configurada' = if the local session is configured). This clearly distinguishes it from sibling tools which all deal with music operations (liked songs, playlists, search).

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 description provides context on what the tool does and the effect of the 'verify' parameter, but it does not explicitly state when to use it versus alternatives, nor does it mention any exclusions or prerequisites. Usage is implied as a preliminary status check, but this is not stated.

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