iaas_create_vsphere_storage_profile

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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true and destructiveHint=false, so safety signalling is covered. The description adds nothing beyond the POST path: it does not say whether the class takes effect immediately, whether names must be unique, or what happens to association sub-specs with requestType CREATE/UPDATE/DELETE. It does not contradict the annotations.

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?

Very short and front-loaded, so there is no wasted prose, but the second line merely restates the HTTP route already present in the annotation title—space that could have carried a prerequisite or a sibling reference.

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?

This is a non-idempotent mutation with a large nested specification object, no output schema, and heavy prerequisite data (region, storage policy, datastore associations). Given that complexity, a two-line description leaves out prerequisites, uniqueness/error behavior, and what the response returns.

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 only two top-level parameters (body, apiVersion) and deeply documented nested fields, so the schema carries the meaning. The description adds no additional parameter guidance, which is the baseline-3 case.

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 (create vSphere storage class), and the 'vSphere' qualifier does separate it from the AWS/Azure/GCP create-storage-profile siblings. However, it never distinguishes itself from the generic iaas_create_storage_profile or from iaas_update_vsphere_storage_profile, and the second line is just the HTTP route.

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 guidance, no prerequisites (a regionId and typically a vSphere storage policy or datastore association from iaas_get_fabric_vsphere_storage_policies are needed), and no mention of the update/delete alternatives. The only cue is the endpoint path.

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