VPS_getVirtualMachinesV1

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

No annotations provided. The description only states the basic action ('Retrieve') without disclosing behavioral traits such as rate limits, authentication requirements, or whether it supports pagination. For a read operation with zero annotations, more detail is needed.

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 very concise with two front-loaded sentences. No unnecessary information, and each sentence adds value.

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 list endpoint with no parameters and no output schema, the description is mostly complete. It could mention that it returns a list of virtual machines, but the purpose is clear. Minor gap but acceptable.

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 input schema has zero parameters, so the description does not need to add parameter details. The baseline for no parameters is 4, and the description is adequate.

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 ('Retrieve') and the resource ('all available virtual machines' or 'VPS instances'). It distinguishes this tool from siblings like VPS_getVirtualMachineDetailsV1 which retrieves details of a single VM.

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 context for when to use (to view available VPS instances) but lacks explicit guidance on when not to use or alternatives. Among siblings, there is no mention of preferring another tool for filtered or detailed views.

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