List public IPs by isolated network

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds nothing beyond the scope statement — no note on pagination behavior, empty results, or what a public IP record contains — so it contributes little behavioral context.

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?

A single front-loaded sentence with no filler or redundancy. It is appropriately sized for a simple list tool, though it is arguably terse enough that one clause about scoping versus the global list_public_ips would have paid for itself.

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 three-parameter, read-only list tool with full schema coverage and complete annotations, nothing essential is missing; there is no output schema, so return values need not be explained. The only shortfall is the absence of sibling routing guidance between the three public-IP list variants.

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 100%, with isolatedNetworkId (UUID), page and pageSize all documented including defaults and max. The description only restates that a network must be specified; baseline 3 applies since the schema carries the parameter semantics.

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?

States a specific verb and resource (list public IPs) plus the scoping constraint 'within a specific isolated network', which distinguishes it from the sibling list_public_ips and list_public_ips_by_vpc. It does not explicitly name those alternatives, so the differentiation is implicit rather than stated.

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?

No when-to-use or when-not-to-use guidance is given. An agent must infer from the phrase 'within a specific isolated network' that this is the isolated-network-scoped sibling of list_public_ips / list_public_ips_by_vpc; no alternatives or prerequisites are mentioned.

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