get_vm_guest_identity

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states a generic 'Get' operation. It does not mention whether the VM must be powered on, if guest tools are required, or any side effects. The agent cannot infer constraints or behaviors from the description alone.

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 sentence that front-loads the verb and resource. It is concise but at the expense of necessary detail. It is appropriately sized for a simple idea but lacks completeness for the tool's context.

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?

Given the presence of an output schema, the description need not detail return values, but it should still cover essential context. It fails to mention dependencies (e.g., guest tools), potential failure modes, or how this tool relates to sibling tools. The agent is left with an incomplete understanding.

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%, so the description should compensate by explaining parameter meanings. However, it does not mention the 'vm' or 'vcenter_name' parameters at all. The agent must guess the format or purpose (e.g., whether 'vm' is an ID or name) from the schema's minimal type information.

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 'Get guest identity details for a VM.' clearly states the verb ('Get') and the resource ('guest identity details for a VM'). It distinguishes from sibling tools like get_vm_cpu or get_vm_memory by focusing on identity details, though it does not specify what those details are (e.g., OS, hostname).

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?

There is no guidance on when to use this tool vs. alternatives. Among many get_vm_* and list_vm_* siblings, the description offers no context on prerequisites (e.g., guest tools), nor does it indicate what scenarios are appropriate for this tool.

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