iaas_enumerate_aws_regions_async

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

Annotations already declare the safety profile (readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false). The description adds that it targets a specified AWS account but omits the key behavioral trait of an async POST: that it likely returns a request tracker requiring polling for the region list. This is a genuine gap beyond the annotations.

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?

One sentence front-loads the purpose, followed by the raw endpoint path. Efficient, though the trailing URL fragment adds little for an agent and slightly clutters the definition.

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 asynchronous enumeration tool with no output schema, the description should explain the async pattern and how to retrieve results. It instead leaves the agent with only a one-line purpose and an endpoint path, so it is not complete enough to invoke-and-follow-up 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 coverage is 100%, and the schema itself explains the accessKeyId/secretAccessKey vs cloudAccountId alternatives and the apiVersion format. The description only implies the cloud-account target and adds no syntax or format detail beyond the schema, 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 (get) and resource (available AWS regions) scoped to a specified cloud account. It is distinguishable from the azure/gcp/vmc siblings by name and text, though the async behavior implied by the name is not explained.

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 guidance on when to use this versus the other enumerate_*_regions_async siblings or the generic iaas_enumerate_regions_async. Critically, the async workflow (that results must later be fetched via iaas_get_region_enumeration_result) is never mentioned despite that sibling existing.

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