e2e_delete_volume

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 usefully discloses that deletion is permanent/irreversible and only valid for unattached volumes, but says nothing about required permissions, the failure behavior for attached volumes, or the response shape.

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?

A single tight sentence with the destructive nature and precondition front-loaded. No filler or redundant restatement of the name.

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 tool with no annotations and no output schema, the description covers the essential action and its precondition but omits permissions, error conditions, and confirmation of irreversibility against attached volumes. Adequate but with clear gaps.

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 block_id, location, and project_id are already documented in the schema. The description adds no syntax, format, or interaction detail for these parameters, so the baseline 3 applies.

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 (delete), a precise resource (block storage volume), a permanence qualifier, and a precondition (unattached). This naturally distinguishes it from e2e_detach_volume (which keeps the volume) and e2e_create_volume, so an agent can select correctly without opening schemas.

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 word 'unattached' implicitly conveys a precondition and hints that detachment (e2e_detach_volume) must precede deletion, but the description never states when to use this tool versus alternatives or what happens if the volume is attached. Usage is implied rather than explicit.

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