Create volume snapshot

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

There are no annotations, so the description carries the full behavioral disclosure burden. It only repeats that a snapshot is created; it does not state whether the volume must already exist, whether creation is synchronous, what side effects occur, or what the response contains. This is slightly better than a pure tautology but still lacks meaningful behavioral transparency.

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 one short, front-loaded sentence with a supporting docs link. There is no wasted wording, and the core purpose appears immediately.

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 four parameters, no annotations, no output schema, and no parameter descriptions, this description is far from complete. It does not explain how to invoke the tool correctly, what 'name' refers to, or what the operation returns. The external docs link is not a substitute for inline tool definition context.

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 0% and the description adds no parameter meaning. The required 'name' property is ambiguous—it is not clarified whether it is a volume name or snapshot name—and labels, backupMode, and snapshotName are left entirely unexplained.

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 action and resource: 'Create a snapshot of a volume.' This is specific enough to distinguish it from list/get/delete/revert snapshot tools, but it does not explicitly contrast it with sibling tools such as volume_snapshot_backup or volume_snapshot_cr_create.

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?

No usage guidance is provided. The description does not say when to use this tool instead of volume_snapshot_backup, volume_snapshot_cr_create, or snapshot_list, and it gives no prerequisites, exclusions, or context about the target volume. A docs URL is referenced but not integrated into actionable guidance.

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