hcloud_list_organizations_ous

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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that – no note on whether results are hierarchical, paginated, or scoped to an account/region.

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 a single short phrase with no wasted words, but it is under-specified rather than concise. The awkward 'Organizations organizational units' construction could be tightened and front-loaded with the filtering behavior.

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 two-parameter list tool with full schema coverage and annotations, the definition is barely adequate. It leaves unclear whether the call returns a flat list or a tree, and whether parent_id is required for meaningful results.

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%, so both region and parent_id are documented in the schema and the baseline of 3 applies. The description fails to mention that parent_id filters to child OUs, which would have been the one piece of meaning worth adding.

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?

Names a specific verb (List) and resource (Organizations organizational units/OUs), but the phrasing is garbled and does nothing to distinguish it from siblings such as hcloud_list_organizations_accounts. An agent can infer it enumerates OUs, but not what an OU represents in this API.

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 guidance, no mention of the region prerequisite, and no statement about whether parent_id narrows the listing or is optional for a full enumeration. Alternatives are not referenced.

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