reserved_ip_list_unattached

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

With no annotations provided, the description carries the full burden. It indicates a read-only operation via 'List' and adds 'all' to suggest completeness, but it does not mention pagination, sorting, or potential behavior such as empty results. There are no obvious side effects, but the lack of any safety signal or additional context keeps this at a mid score.

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 two sentences, but the second sentence ('Returns: List...') largely repeats the first sentence's content. It is still efficient and front-loaded, but the redundancy prevents a perfect score.

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 that this is a zero-parameter list operation with an output schema present, the description is sufficient for an agent to understand the purpose and expected result. It does not need to explain parameters or return shaping, as those are covered elsewhere. It is complete enough for a tool of this simplicity.

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 tool has zero parameters)Skip justification. With schema coverage at 100% and no parameters to describe, the baseline is 4. The description correctly omits parameter information because none exists.

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 uses a specific verb ('List') with a precise resource ('reserved IPs') and a clear scope ('unattached'), distinguishing it from siblings like reserved_ip_list_attached and reserved_ip_list_by_region. An agent can determine exactly what this tool does without inferring anything.

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 explicit guidance on when to use this tool versus alternatives such as reserved_ip_list_attached or reserved_ip_list_by_region. The usage is implied by the word 'unattached,' but the description does not state exclusion criteria or when another list tool would be more appropriate.

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