iaas_get_external_network_ip_ranges

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered upstream. The description adds only the raw GET path, which repeats the read semantics rather than adding anything new such as pagination behavior, result limits, or scope of the external IPAM data returned.

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?

Three lines convey one idea; the second line is a verbatim amplification of the first and the third is just the endpoint path. It is short but redundant rather than economical, and none of the space is used to front-load distinguishing information.

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 read-only list with no output schema and full annotation coverage, the description is minimally sufficient — an agent can call it. It still omits whether results are paginated or what the response collection contains, which matters for a listing endpoint over a potentially large set of ranges.

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% for the single optional apiVersion parameter, and the schema already explains the yyyy-MM-dd format and the /iaas/api/about reference. The description adds no parameter meaning beyond that, so the baseline of 3 applies.

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 names a specific verb and resource ('Get all external IPAM network IP ranges'), so an agent knows this is a list operation over external IPAM ranges. However it offers no differentiation from close siblings such as iaas_get_external_network_ip_range (singular), iaas_get_internal_network_ip_ranges, or iaas_get_external_ip_blocks, and the three lines merely restate each other.

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 statement of when to use this tool versus the singular getter or the internal-range equivalent, and no prerequisites or context conditions are given. Usage has to be inferred entirely from the name.

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