zabbix_validar_conexao

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

With no annotations, the description carries the full burden; it does disclose the four dimensions being validated, which gives useful behavioral context beyond the empty schema. However, it says nothing about whether the call is read-only/safe, whether credentials must already be configured, how failures are surfaced, or whether any state is mutated. Listing the checks is real value, but the safety profile remains undisclosed.

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?

A single tight sentence with the verb front-loaded and the checks enumerated after. Nothing is wasted except the stray '91.' prefix, which should have been stripped. Well-sized for a zero-parameter tool.

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 zero-param probe with an output schema, the description covers what is validated and needs not explain return values. What it leaves out is the surrounding workflow: whether this is a precondition check, what to do on failure, or which sibling to use for deeper diagnosis. Adequate, but with a clear contextual gap.

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, so the baseline is 4; the schema is fully self-sufficient. The description's mention of URL, authentication, and API version implicitly tells the agent what configuration must exist beforehand, which is a modest bonus. Nothing is missing that parameter documentation could supply.

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?

States a specific verb ('Validar') plus the exact resource set checked: URL, network connectivity, authentication, and Zabbix API version. This distinguishes it from most siblings, though it never explicitly contrasts with near-neighbors like zabbix_diagnosticar_ambiente or zabbix_consultar_estado_sistema. The leading '91.' is an unexplained numbering artifact that adds noise to an otherwise clear sentence.

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 indication of when an agent should call this — e.g., as a prerequisite before batch operations, or as the first step of troubleshooting. The adjacency to zabbix_diagnosticar_ambiente and zabbix_consultar_estado_sistema is left entirely unaddressed. An agent must infer invocation context purely from the tool name.

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