iaas_enumerate_regions_async

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

Annotations cover safety (destructiveHint=false, openWorldHint=true), but the description omits the single most consequential trait: this is an *async* operation whose name and 'POST' path imply it kicks off work that must be polled, presumably via iaas_get_region_enumeration_result or iaas_get_request_tracker. It also doesn't mention that callers supply credentials (privateKey/privateKeyId) in the request body, or that 'Get' here is a POST that annotations mark readOnlyHint=false — a tension an agent should know about.

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 lines with no filler, but the second line is a raw HTTP path that gives an agent little beyond what the name already says. The brevity is under-specification rather than efficiency — the space freed up was not spent on the async flow.

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?

For an async, 2-required-parameter tool with nested credential objects and no output schema, the description should explain that it initiates enumeration and how to retrieve the eventual regions. Neither the polling path nor the sibling to call next is named, leaving a real gap in a complex flow.

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 either/or between cloudAccountId and the privateKeyId/privateKey credential pair is fully documented inside the schema. The description adds no additional meaning about apiVersion or the body shape, so 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?

States a specific verb+resource: retrieve available regions for a cloud account, with the target endpoint appended. It is clear what the tool produces, but it never distinguishes itself from the many provider-specific siblings (iaas_enumerate_aws_regions_async, iaas_enumerate_azure_regions_async, iaas_enumerate_vcf_regions_async, etc.) or from iaas_get_regions, so the agent cannot tell when this generic variant is the right one.

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, when-not-to-use, or prerequisite guidance. Nothing says whether this generic tool is a fallback when a provider-specific enumerator doesn't exist, or whether it should be preferred over iaas_get_regions / iaas_get_region_enumeration_result.

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