Get VM IP Address

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

The description adds context beyond annotations by specifying the wait behavior and the dependency on VMware Tools. It does not contradict the readOnlyHint or idempotentHint. Minor omission: it does not mention the vm_password parameter.

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 concise and well-structured with Args and Returns sections. Every sentence contributes to clarity, with no redundant content beyond the schema.

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 simple nature and the presence of annotations, the description adequately covers prerequisites, wait behavior, and return value. However, the omission of vm_password from the Args list is a small completeness gap, even though the schema documents it.

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 schema fully describes all three parameters (100% coverage), so the baseline is 3. The description's Args section duplicates the schema information for vmx_path and wait, and omits vm_password entirely, adding no extra semantic value.

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 tool's function: retrieving the IP address of a VMware Fusion guest. The verb 'Get' and resource 'IP address' are specific and differentiate it from sibling tools like fusion_get_vm_info or fusion_list_running.

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?

It provides explicit operational prerequisites: the VM must be running and VMware Tools installed. It does not explicitly discuss when not to use or alternatives, but the context is clear.

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