zabbix_testar_canal_notificacao

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 signals a caution, but never states that this is a side-effecting operation that dispatches an actual message, what the confirmar_envio flag gates, or whether the action is reversible or has rate/permission constraints. For an action tool with zero annotation coverage this is a substantial gap.

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?

It is a single short sentence with no padding, which is good, but the "55." numbering artifact is pure noise and the front-loaded position is spent on the artifact rather than on the action.

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?

An output schema exists so return values need not be explained, but the description still leaves the agent without the essentials: what a test does end-to-end, which parameters drive it, and what safety gating applies. Given four undocumented parameters and no annotations, the definition is under-specified for correct invocation.

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% across four parameters (mediatypeid, destinatario, mensagem, confirmar_envio) and the description says nothing about any of them. The meanings of mediatypeid vs destinatario vs the confirmation flag are left entirely to inference from Portuguese field names.

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 verb+resource are identifiable ("testar um canal", i.e. test a notification channel), which matches the tool name and distinguishes it from read-only siblings like zabbix_listar_canais_notificacao. However, the leading "55." artifact and the phrase "somente em ambiente e condições autorizados" consume most of the sentence without clarifying what a channel test actually does (sends a real message via a media type to a recipient).

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 only guidance is a blanket restriction ("somente em ambiente e condições autorizados") with no criteria for what counts as authorized, and no comparison to alternatives such as merely listing channels or consulting notification history. An agent learns a caution but not when this tool is the right pick.

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