block_storage_delete

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

No annotations are provided, so the description carries the full burden. It discloses deletion and return values, but does not state that deletion is permanent, what happens if the volume is attached to an instance, or whether confirmation is required. This is a significant gap for a destructive operation.

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 and front-loaded, with a clear first sentence followed by args and returns. The only structural flaw is listing ctx as an argument even though the schema does not include it.

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 single-parameter tool with an output schema, the basics are covered: what it deletes, how to identify the volume, and that it returns confirmation. But the absence of behavioral warnings and any route to alternative tools leaves it merely adequate rather than fully complete.

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 coverage, the description compensates by explaining that volume_identifier accepts 'Volume label or ID.' This is the key detail an agent needs. However, it also lists a ctx argument that is absent from the input schema, causing slight ambiguity.

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 'Delete a block storage volume,' naming a specific verb and resource. This clearly separates it from sibling operations like block_storage_attach, block_storage_detach, and block_storage_update.

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?

There is no guidance on when to choose this over alternatives such as block_storage_detach, nor any mention of prerequisites like listing volumes first. The 'smart identifier resolution' note explains how to identify a volume, not when deletion is appropriate.

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