iaas_create_vsphere_cloud_account_async

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false, so the safety profile is covered structurally. The description adds essentially nothing beyond that: it does not explain the async behavior (what a request tracker / task ID is returned), whether duplicate names are allowed, or that credentials are validated against a live vSphere endpoint. "In the current organization" is the only extra 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?

It is short, but the first two lines are near-duplicates ("Create a cloud account" / "Create a cloud account in the current organization") and the endpoint line carries most of the actual signal. Redundancy without harm, but a sentence is wasted.

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 mutation tool with a large nested body and no output schema, and the async contract — that creation is tracked as a request and must be polled — is never explained. The schema covers the payload well, but an agent still lacks the operational picture (async polling, credential validation, validateOnly dry-run) needed to use it correctly.

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 every body property, including validateOnly and the nested regions/certificateInfo objects, is documented in the schema itself. The description contributes no additional parameter meaning, so the baseline 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 states the verb and resource ("Create a cloud account in the current organization"), and the endpoint path "/iaas/api/cloud-accounts-vsphere" implies vSphere specificity. However, the prose never says vSphere, never mentions that this is an asynchronous operation (despite the tool name), and the first two sentences restate each other rather than adding distinct information. It is adequate but leaves differentiation from iaas_create_cloud_account_async largely to the URL.

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, when-not-to-use, or prerequisite guidance is given. Nothing tells the agent to prefer this over iaas_create_cloud_account_async or iaas_create_vmc_cloud_account_async, nor that credentials and a data collector are typically required first. Usage must be inferred entirely from the endpoint path.

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