hcloud_delete_placement_group

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

The annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is known without the description. The description adds nothing beyond that: it does not say the deletion is irreversible, what happens to member servers, or whether the call fails when the group is still in use. For a destructive mutation, that is a real gap even though the baseline bar is lower.

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 description is short, but its second sentence is a verbatim restatement of the first, so it does not earn its place. Being under-specified rather than concise is its main problem; it conveys no information beyond the tool name repeated twice.

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?

This is a destructive resource-deletion tool with no output schema; the description should therefore cover irreversibility, preconditions, and the effect on dependent resources. None of these topics are addressed, so an agent has to guess about consequences that the structured fields do not capture.

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?

There is a single parameter, id, whose schema description ('ID of the Placement Group.') has 100% coverage and includes type, format, example, and bounds. By the baseline rule, a 3 is appropriate: the schema does all the work, and the description adds no identifier semantics such as whether it is the numeric ID or the name.

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 only restates the tool name: 'Delete a PlacementGroup / Deletes a Placement Group.' The verb and resource are identifiable, but it gives no more information than the name already does. Because the name is prefixed with hcloud_ and followed by the resource, an agent can distinguish this tool from siblings such as hcloud_delete_server or hcloud_delete_network from the name alone; the description adds nothing to that distinction.

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?

The description contains no statement about when to use this tool, when to avoid it, or which alternatives exist. It does not mention that the Placement Group must be empty, that servers assigned to it must first be removed (hcloud_server_remove_from_placement_group_action), or when to use hcloud_list_placement_groups first. No context is given beyond the bare action.

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