iaas_update_vsphere_storage_profile

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the description's only added content is the PATCH path, which merely restates the partial-update nature. It adds nothing about whether omitted fields are reset, whether datastore associations are rebuilt, or what the response contains, which matters for a non-idempotent mutation.

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?

Two short lines with no filler and the resource is front-loaded, but the second line is API plumbing (PATCH path) that yields little for tool selection, so brevity here comes at the cost of substance rather than earning its place.

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?

Annotations cover the safety profile and the schema fully documents all three parameters including the nested body, so the essentials are present elsewhere. What is missing is operational context specific to a vSphere storage-profile PATCH: whether the body is a full replacement of the profile specification and whether changes take effect immediately on existing disks.

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% and the deeply nested body specification documents fields such as diskType, storageFilterType and the deprecated datastoreId inline. The description adds no semantics beyond the schema, so the baseline 3 is appropriate.

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 gives a verb (Update) and a provider-qualified resource (vSphere storage profile), which does separate it from the AWS/Azure/GCP storage-profile variants in the sibling list. However, it is essentially a restatement of the tool name plus the HTTP path, and it does not distinguish this operation from close siblings such as iaas_replace_storage_profile or iaas_update_storage_profile_associations, nor say what parts of the profile are actually updatable.

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 when-to-use guidance, no mention of the replace-vs-patch alternative, and no stated prerequisites (e.g. that the profile must already exist or that the caller needs an authenticated IaaS session). The agent is left to infer usage purely from the name.

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