e2e_create_volume

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: no statement about idempotency, failure behavior, whether the volume starts unattached, or whether the operation is billable. The word 'independent' is the only hint about lifecycle, and it is unexplained.

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 well-formed sentence with no filler and the verb front-loaded. There is nothing to trim, though there is also no structure beyond that one sentence.

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 creation tool with a fully documented schema and no output schema, the basics are covered, but with zero annotations the description should say more about what happens after creation and how the volume relates to attach/detach siblings. It is minimally viable rather than 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?

Schema description coverage is 100%, with each of the five parameters (name, size, iops, location, project_id) documented including examples and a default. The description adds no parameter meaning beyond that, 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?

The description pairs a specific verb ('Create') with a precise resource ('independent block storage volume on E2E Cloud'), so an agent immediately knows what the tool produces. It does not explicitly differentiate itself from siblings such as e2e_create_bucket or e2e_create_database, but the resource noun makes the distinction obvious anyway.

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 use this tool versus alternatives, nor any prerequisites such as required project context or quota limits. It also fails to mention the natural follow-up step (e2e_attach_volume) for a volume that is deliberately created detached.

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