iaas_update_cloud_account_async

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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false and openWorldHint=true, so the safety profile is covered elsewhere. The description adds nothing beyond restating the operation: it does not explain what is replaced versus patched, that the 'async' suffix implies a request tracker must be polled, or that omitting optional body fields may have side effects.

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 and front-loaded, but the first two lines are near-duplicates ('Update CloudAccount' / 'Update a single CloudAccount') and the third is just the HTTP route. Little of the text earns its place, though nothing is bloated.

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 on a complex nested body with no output schema, and the description says nothing about return shape, async operation tracking, reversibility, or error modes. Given the tool's complexity, the definition is substantially under-specified even accounting for the rich schema.

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 nested body properties (regions, privateKey, certificateInfo, associatedMobilityCloudAccountIds) are all documented in the schema. The description introduces no additional meaning about the id path parameter or the version requirement, 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 a specific verb and resource ('Update a single CloudAccount'), so an agent knows this is a mutation of a cloud account record. It does not, however, differentiate itself from provider-specific siblings such as iaas_update_aws_cloud_account_async or iaas_update_vsphere_cloud_account_async, which is the key ambiguity here.

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 generic update versus the many provider-specific update siblings, nor on prerequisites such as the account type or required permissions. The only usage signal is the raw PATCH path, which is structural rather than advisory.

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