get_host

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

No annotations are provided, so the description must convey behavioral traits. It only says 'get details' without mentioning authentication requirements, side effects (none expected), rate limits, or pagination. For a read operation, minimal transparency is offered.

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 concise sentence, but it omits crucial details about parameters and usage. Conciseness in this case leads to under-specification, not efficiency. A bit more structure with parameter guidance would improve it.

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?

Despite the presence of an output schema (which can explain return values), the description lacks parameter semantics and usage context. With two parameters (one required) and zero explanation, the tool is incomplete for an agent selecting and invoking it correctly.

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%. The description does not explain the two parameters ('host' and 'vcenter_name'). It fails to clarify acceptable formats, sources, or the role of the optional 'vcenter_name' parameter. With zero parameter info, the description is severely lacking.

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 clearly states the action ('Get details'), the resource ('specific physical ESXi host'), and the method ('via the vSphere Web Services API'). It effectively distinguishes from sibling tools like 'list_hosts' and other 'get_*' tools that target different entities.

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 description provides no guidance on when to use this tool versus alternatives (e.g., 'list_hosts' for listing all hosts, or other 'get_*' tools for different resources). There are no explicit context or exclusion criteria.

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