iaas_get_region_enumeration_result

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds no behavioral context beyond that: it never says whether the enumeration may still be in progress, how a pending/failed result is signalled, or what the response contains — which is the key trait for a result-retrieval endpoint.

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 nearly the same thing, then the REST path repeats the information a third time. It is short, but a third of the text is redundant rather than additive.

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 a two-parameter getter with annotations covering safety and a schema fully documenting inputs, the definition is minimally sufficient. The missing piece is the async relationship to the enumerate siblings and any hint about response shape, since there is no output 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 coverage is 100%: both id and apiVersion are fully documented in the schema. The phrase 'for a given id' restates the id parameter without adding format or provenance details, so the schema is doing all the work and 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 names a specific verb and resource: retrieve the region enumeration response for a given ID, and includes the REST path as corroboration. It is clear what the tool returns, but it doesn't distinguish itself from the many region-enumeration siblings (e.g. iaas_enumerate_regions_async) or explain that this is the retrieval half of an async operation.

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 statement of when to use this versus the enumerate_*_regions_async siblings, and no indication of where the required id comes from. An agent must infer that this reads the result of a previously initiated enumeration request; nothing in the text guides that sequencing.

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