hcloud_show_public_ip

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

This is a pure read tool, and the annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered. The description adds no behavioral context beyond the annotations: it does not say what 'details' includes, what happens if the ID or region is invalid, or whether the lookup is per-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?

The single sentence contains no waste and is front-loaded with the verb. However, it is too terse to make that sentence earn its place when compared with what an agent still needs to know.

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 full schema coverage and complete annotations, the level of detail is borderline adequate. What is missing is a brief note on the returned details or the relationship to the list tool; however, without an output schema, that gap is relatively minor.

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%, so both required parameters are documented, but only minimally ('Region', 'Public IP ID'). The description contributes nothing beyond that, so it does not compensate for the vague schema text; the baseline of 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?

The description names a specific verb and resource ('Get details of a specific elastic public IP'), which is much clearer than the tautological title. It does not differentiate from the sibling hcloud_list_public_ips, but the single-object scope is still unambiguous.

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 guidance on when to use this versus hcloud_list_public_ips, and no mention of prerequisites such as needing a known publicip_id or region first. The agent must infer that a single-ID lookup is the right choice.

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