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

Annotations already communicate that this is a non-read-only, non-idempotent but non-destructive action. The description adds valuable behavioral context beyond the annotations by specifying that the appointment is registered on behalf of the token owner—an important attribution detail. It does not contradict the annotations, and no additional side effects like duplicate creation are described, but the added user-context justifies the score.

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, front-loaded sentence in Portuguese that efficiently conveys the action, resource, and ownership context. There is no filler or redundancy, and every phrase contributes to understanding the tool's function.

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?

The tool is a straightforward create operation with five required parameters and no output schema. The description covers the key ownership nuance and the action, but lacks details on parameter formats, validation, or what the tool returns. Given the annotations handle safety semantics, the description is minimally adequate but not fully complete for an AI agent.

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?

With 0% schema description coverage, the description carries the full burden of explaining parameters, but it only implies 'chamado' (ticket) and 'apontamento de horas' (time appointment). It does not explain date/time formats, the meaning of init_time/end_time, or the description field. This is minimal compensation for undocumented parameters.

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 ('Lança') and identifies the resource as 'apontamento de horas num chamado' (a time appointment on a ticket), clearly distinguishing this create operation from sibling list tools like tiflux_list_appointments. It also clarifies the acting principal ('em nome do usuário dono do token'), making the purpose unmistakable.

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 explicit when-to-use or when-not-to-use guidance is provided. The usage context is only implied by the verb 'criar/launch' and the mention of 'apontamento de horas', which contrasts with listing siblings, but the description does not explicitly advise on alternatives or prerequisites.

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