iaas_get_vsphere_storage_profiles

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the description's job is to add context such as pagination, filtering, or what an empty result means. It adds none of that, only restating the purpose and the raw GET path.

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 say the same thing twice ('Get vSphere storage classes' / 'Get all vSphere storage classes') and then repeat the raw endpoint path. The repetition crowds out the space where usage or behavioral detail could have gone.

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 trivial read-only list endpoint with one optional version parameter and no output schema, the description is minimally sufficient to call it. It still leaves return shape, pagination, and any filtering behavior unspecified, so it is adequate rather than complete.

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?

There is a single optional apiVersion parameter with 100% schema description coverage, so the schema already carries the semantics. The description contributes nothing additional about the version parameter or its default, which meets the baseline-3 expectation but no more.

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 states a clear verb plus resource ('Get all vSphere storage classes') and the vSphere scope implicitly separates it from the AWS/Azure/GCP storage-profile siblings. It does not explicitly distinguish the singular iaas_get_vsphere_storage_profile or the generic iaas_get_storage_profiles, so routing still requires inference.

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 versus the single-profile getter, the generic storage-profile list, or the fabric vSphere storage policies. The only implicit cue is the 'all' versus singular naming, which is left for the agent to notice.

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