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

No annotations are provided, so the description carries the behavioral burden. It discloses the core behavior: the tool reports validity and expiration date. The stative verb 'diz' implies a read-only query rather than a mutation, which is helpful. It does not mention auth, errors, or side effects, but those are secondary for a zero-parameter status check.

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 short, front-loaded sentence with no filler, repetition, or redundant schema information. Every word contributes to the meaning.

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 status-check tool with zero parameters, no annotations, and no output schema, the description conveys the essential behavior and result. Minor gaps are that 'dono' (owner) is not explicitly defined as the currently authenticated user, and no guidance is given about related nsfw tools.

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 input schema has no properties, so there are no parameter semantics to clarify. The baseline of 4 applies because parameter explanation is unnecessary.

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 ('Diz' / 'tells') and clearly identifies the resource ('o passe adulto do dono' / the owner's adult pass) and the information returned (validity and expiration). It is clear, but it does not explicitly distinguish itself from sibling tools like nsfw_consent_status or nsfw_pass_buy.

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 intended usage is implied: call this tool to check whether the owner's adult pass is valid and when it expires. However, there is no explicit guidance about when to use this versus alternatives, and no reference to related sibling tools.

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