hcloud_list_cci_namespaces

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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so the safety profile is fully covered without the description. The description adds nothing beyond expanding the acronym - no note on whether all namespaces in the region are returned, pagination, or whether the region scopes the query.

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?

A single short sentence with the resource front-loaded and zero filler. It is efficient, though the same brevity is what leaves the other dimensions thin.

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 one-parameter read-only list tool with annotations and no output schema, this is minimally sufficient to call correctly. It stops short of describing what a returned namespace looks like or how results are scoped, which an agent discovering CCI resources would benefit from.

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% for the single 'region' parameter, so the description does not need to restate it. However, the schema's own text is only 'Region', and the description does nothing to clarify region format or whether it narrows the namespace listing, leaving it at the baseline.

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 states a specific verb ('List') and resource ('CCI namespaces'), and expands the CCI acronym, so the agent knows exactly what is returned. It does not distinguish itself from siblings like hcloud_list_cci_deployments or hcloud_list_cci_pods, but the unique resource noun makes the scope unambiguous anyway.

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 prerequisites, and no reference to any alternative tool. The agent must infer from the name alone that this is the entry point for discovering namespaces before calling pod or deployment listings.

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