Detach a volume

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

With no annotations provided, the description carries the full disclosure burden. It does the most important part by warning that detachment can cost a running workload its disk and by requiring an explicit confirm flag. It stops short of stating permission requirements or whether the operation is reversible.

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 tight sentences, zero filler. The risk/reason sentence immediately follows and justifies the confirm requirement, so nothing is buried.

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 mutation with no annotations and no output schema, the description covers the essential risk and the confirm gate. Minor gaps remain: reversibility, auth/permission needs, and whether the server must be stopped first.

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%, so both parameters are already documented ('Volume id.', 'Must be true.'). The description echoes confirm=true and adds the rationale for it, which is mildly useful, but adds little semantic detail beyond the schema baseline.

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 opens with a specific verb+resource: 'Detach a volume from its server.' This clearly distinguishes it from the sibling tools cloud_attach_volume and cloud_delete_volume without requiring the schema to be opened.

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?

It states a concrete prerequisite (confirm must be true) and the condition that motivates it (a running workload may lose its disk). It does not name alternatives or state when-not-to-use, but the gating requirement gives clear invocation context.

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