Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses none. It does not state that this is a read-only operation, whether any permissions are required, or whether the listed items are always returned. Listing content categories is not the same as disclosing behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

It is a single front-loaded sentence with the resource named first, which is good structure. However, the long comma-separated enumeration becomes dense to parse and includes low-level detail (link speed, masked key) that adds bulk without direction.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no annotations, the description does useful work by listing the configuration domains returned, which partially compensates. But it omits the verb, any usage context, and any behavioral or permission details, leaving the definition only minimally viable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so per the rubric the baseline is 4. The description correctly requires no argument explanation; the metadata is trivially complete on the input side.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description enumerates what the tool covers (license, NTP, SSH, services, VIBs, syslog, NICs, vSwitches, portgroups, VMkernel) under the label 'Configuracion del host', so the resource is clear. But it never states a verb or the action ('retrieve/report configuration'), leaving the actual operation inferred. It also does not differentiate itself from close siblings like host_info or salud_hardware.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives. Sibling tools such as host_info, salud_hardware, and diagnostico_completo overlap heavily, yet none is referenced or excluded. The agent must guess the retrieval context.

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