hcloud_volume_attach_action

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

Annotations already flag this as a mutating, non-read-only operation, so the main added value is the same-Location requirement. The description says nothing about the automount side effect on the server's filesystem, whether attachment is reversible, or that the optional wait parameter polls the resulting action — all material for an agent deciding whether to call it.

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?

Two short sentences, the precondition front-loaded alongside the action. Nothing extraneous.

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 mutation with no output schema and an async action model (wait polls until success/error), the description omits return semantics and the automount consequence. The Location constraint covers the main failure mode, but side effects and action-polling behavior are left unexplained.

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 67% and the schema documents id, server, automount and wait individually. The description adds no parameter-level information at all, notably omitting the behavioral meaning of automount and wait, so it sits at the baseline for partially-documented params.

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: attaches a Volume to a Server. It is clear against the sibling hcloud_volume_detach_action and unrelated volume tools, though it doesn't name the inverse operation explicitly.

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 Location-matching precondition is a useful constraint that tells the agent when the call will fail, but there is no guidance on when to attach versus resize/detach, nor how it relates to the sibling volume action tools.

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