iaas_get_region

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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds nothing beyond the raw REST path — no note about what a region object contains, error behavior for an invalid id, or enumeration status. It neither contradicts nor enriches 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?

It is short and front-loaded, but the first line duplicates the tool name and the second largely repeats it, so one of the three lines is wasted. Brevity here reflects under-specification rather than tight editing.

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 simple read-by-id endpoint with a fully described two-parameter schema and read-only annotations, the minimum is nearly met. However, with no output schema, the description should at least indicate that it returns a single region object and what identifies it, which it does not.

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%, including the `id` path parameter and `apiVersion`, so the schema does the heavy lifting. 'With a given id' only confirms what the schema already says; 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 is a near-verbatim restatement of the tool name and title: 'Get Region' / 'Get Region with a given id'. The only value added is the singular 'with a given id', which is implied by the required `id` parameter, and nothing distinguishes it from the sibling list operation `iaas_get_regions`.

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 versus `iaas_get_regions` (list) or `iaas_get_region_enumeration_result`. The agent must infer the singular-vs-plural split purely from the tool name.

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