iaas_enumerate_vmc_regions_async

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

Annotations declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false, but the description only says 'Get' and shows a POST path. It does not disclose that this initiates an asynchronous enumeration operation, what it creates or returns, or how the caller should obtain the eventual result, leaving a significant behavioral gap.

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 description is short and front-loaded, with the core purpose in the first sentence and the endpoint appended. It contains no filler, though the endpoint line largely duplicates the title and the brevity comes at the cost of important async context covered elsewhere.

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 an async POST operation with a complex nested input and no output schema, yet the description does not explain the asynchronous lifecycle, expected return, or how to poll/retrieve the enumeration result. The schema covers parameters well and annotations cover safety traits, but the description is not complete enough for correct operational use.

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 schema already documents cloudAccountId, credentials, data collector details, and certificate settings. The description adds only the phrase 'specified VMC cloud account' and does not add meaning 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 states a specific verb and resource for a specific provider: 'Get the available regions for specified VMC cloud account.' That distinguishes it from region tools for AWS/Azure/GCP/VCF/vSphere, but it does not clarify the async enumeration behavior or how it differs from sibling retrieval tools such as iaas_get_regions or iaas_get_region_enumeration_result.

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?

The description gives no explicit when-to-use guidance, prerequisites, or alternatives. In a sibling set with many region-enumeration and region-retrieval tools, an agent is left to infer that this is the VMC-specific enumeration call and that results may need to be retrieved elsewhere.

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