hcloud_list_cce_clusters

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

Annotations already declare readOnlyHint, openWorldHint and idempotentHint, and the description adds nothing beyond them — no note about pagination, region scoping behavior, result size, or what an empty result means. For a read-only list tool with full annotation coverage the bar is lower, but this adds zero behavioral context.

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?

Five words, front-loaded with the verb and resource, and no wasted phrasing. It is arguably over-terse rather than padded, but as raw conciseness it is efficient.

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 read-only lister with a fully described schema, the essentials are covered by the structured fields. However, with no output schema there is no explanation of what a cluster entry contains, and there is no hint about the required region's role, leaving small gaps.

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 the region and status parameters are already documented, including example status values. The description mentions no parameter at all, so it neither compensates nor detracts; 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 and resource ("List ... clusters") and expands the CCE acronym as Kubernetes, so the agent knows what is being enumerated. It does not distinguish itself from siblings such as hcloud_list_cce_nodes or hcloud_show_cce_cluster, so a 4 rather than a 5.

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: nothing says to call this instead of hcloud_show_cce_cluster when full details are needed, or instead of hcloud_list_cce_nodes for node inventory. The only implied context is that it is a list operation.

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