iaas_create_nsx_t_cloud_account_async

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

Annotations already declare readOnly=false, destructive=false, openWorld=true, idempotent=false, so the safety profile is covered. Nothing in the description adds behavior beyond that: the async nature of the operation (the name says _async) and the resulting need to poll a request tracker, the fact that credentials/passwords are transmitted, and any rate-limit or permission requirements are all undisclosed.

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?

The first two lines say the same thing twice, and the third line just restates the endpoint already present in the tool title/annotations. Three lines of text deliver one sentence of information, so it is redundant rather than efficient.

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?

The input schema is fully documented with nested object descriptions and annotations carry the safety signals, so the agent can construct a valid call. The significant remaining gap is that this is an asynchronous create with a credential-bearing body, and the description says nothing about polling the returned request, about validateOnly being present in the schema, or about consequences of failure — meaningfully incomplete for a mutation tool of this complexity.

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%, including the nested body fields (hostName, username, password, dcid, isGlobalManager, certificateInfo), so the schema does the semantic work. The description contributes nothing beyond the endpoint path and adds no meaning such as how validateOnly interacts with creation or what apiVersion values are typical — baseline 3.

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 specific verb and resource ("Create a NSX Manager cloud account in the current organization"), which is more precise than the name alone and clearly separates it from get/update/delete NSX-T siblings. It does not, however, explicitly contrast itself with the many other create_*_cloud_account_async tools, leaving the agent to infer the distinction from the resource noun.

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 guidance on when to use this versus iaas_update_nsx_t_cloud_account_async, iaas_create_cloud_account_async, or iaas_create_vsphere_cloud_account_async, nor any stated prerequisites (permissions, on-prem data collector requirement, that it is async and needs polling). The only contextual hint is "in the current organization."

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