cloud_attach_volume

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

With no annotations, the description carries the full burden but only states the basic action. It does not disclose side effects (e.g., what happens if already attached), permissions required, or whether the call is synchronous or async. Output schema exists but is omitted from description.

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 a single sentence with no fluff, which is concise. However, it sacrifices necessary detail; a slightly longer description could improve completeness without losing conciseness.

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?

Given 3 parameters (including optional automount), no annotations, and an output schema that is not described, the description is insufficient. It lacks prerequisites, return value hints, and behavioral context, making it inadequate for an agent to invoke correctly without additional information.

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 0%, and the description adds no meaning beyond parameter names. The 'automount' parameter, which is optional and nullable, could benefit from explanation (e.g., whether it enables auto-mounting on server boot). The description fails to compensate for the missing schema descriptions.

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 'Attach a volume to a server' uses a specific verb ('attach') and resource ('volume') with a clear target ('server'), effectively distinguishing it from siblings like cloud_detach_volume or cloud_create_volume.

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?

No guidance on when to use this tool vs alternatives (e.g., cloud_detach_volume), no prerequisites mentioned (e.g., volume must be unattached, server must exist), and no exclusions or context provided.

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