hcloud_list_dws_clusters

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 without prose. The description contributes only the acronym expansion and resource scope; it says nothing about whether results are paginated by limit/offset, whether region is mandatory, or how large the listing can get.

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 front-loaded sentence with zero filler or redundancy. It is well structured but so terse that the brevity comes at the cost of guidance, which is why it is not a 5.

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 three-parameter list tool with no output schema and no nesting, this is minimally adequate: the agent knows what it lists and the schema supplies the parameters. Missing are any note about pagination behavior or what a cluster record contains, which an agent planning a call would find useful.

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 region, limit and offset are already documented in the schema, and the description adds no syntax, format, or defaulting detail beyond that. Baseline 3 applies when the input schema carries the parameter burden.

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 pairs a specific verb (List) with a specific resource (DWS clusters) and expands the DWS acronym as GaussDB Data Warehouse, which distinguishes it from the nearby hcloud_list_gaussdb_instances and hcloud_list_mrs_clusters. It stops short of naming those siblings or the corresponding hcloud_show_dws_cluster, so differentiation is implied rather than stated.

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 at all: nothing says to call this before hcloud_show_dws_cluster for details, or why one would pick the DWS cluster list over hcloud_list_dws_flavors. The agent must infer the choice 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.
