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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the 'live' parameter's default behavior and smart identifier resolution, but doesn't disclose important behavioral aspects like: whether this operation requires specific permissions, whether it's reversible, what happens to data on the volume, potential side effects on the instance, or any rate limits. For a destructive detachment operation, this is a significant gap.

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 efficiently structured with a clear purpose statement first, followed by parameter explanations in a labeled format. Every sentence adds value: the main action, identifier resolution guidance, and parameter semantics. No wasted words or redundant information.

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 that this is a destructive operation with no annotations and an output schema exists (implied by 'Returns: Success confirmation'), the description is moderately complete. It covers the basic operation and parameters but lacks important context about permissions, side effects, and error conditions. The existence of an output schema means return values don't need explanation, but behavioral transparency gaps remain significant.

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?

With 0% schema description coverage, the description adds substantial value by explaining both parameters. It clarifies that 'volume_identifier' accepts either label or ID with smart resolution, and explains that 'live' controls whether to detach without rebooting (with a default value). This compensates well for the schema's lack of descriptions, though it doesn't provide format examples for identifiers.

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 clearly states the tool's purpose: 'Detach block storage volume from its instance' - a specific verb (detach) and resource (block storage volume). It distinguishes from sibling 'attach' and 'detach_from_instance' by focusing on volume detachment specifically. However, it doesn't explicitly differentiate from 'detach_from_instance' which appears to be a similar operation.

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 provides implied usage context through the mention of 'smart identifier resolution' and the 'live' parameter's default behavior. However, it doesn't explicitly state when to use this tool versus alternatives like 'detach_from_instance' or what prerequisites might be needed. No explicit when-not-to-use guidance is provided.

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