hcloud_list_public_ips

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 further: it does not say whether results are region-scoped, paginated, or what fields come back, so beyond the annotations it contributes no 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?

Four words, front-loaded with the verb, with zero filler or redundancy. It is efficient, though the brevity comes at the cost of the information gaps scored elsewhere.

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 tool with no output schema, the description still omits that a region is required and whether the list is filtered or truncated. It is not misleading, but an agent cannot call it correctly without reading the schema.

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%, with both `region` (required) and `limit` documented, so the baseline is 3. The description does not clarify whether region is mandatory or how limit interacts with pagination, adding no meaning beyond the schema.

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?

"List elastic public IPs" gives a specific verb (list) plus resource (elastic public IPs), so the basic operation is legible. However, it offers no differentiation from the many similar list siblings, notably hcloud_show_public_ip and hcloud_list_bandwidths, which an agent must choose between.

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 when a single-IP lookup (hcloud_show_public_ip) is preferable, and no stated prerequisites. The agent must infer everything from the tool name alone.

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