Create Snapshot

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

The description discloses that the operation is asynchronous and the snapshot is enqueued, which adds meaningful behavioral context beyond the annotations. It does not contradict the readOnlyHint=false, idempotentHint=false, or openWorldHint=true annotations.

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 two concise sentences with no filler. The core operation is stated first, and the important asynchronous behavior is added in a compact second 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?

Given the simple parameter set, complete schema coverage, and existing annotations, the description covers the essential behavior. It could be slightly stronger by pointing to list_snapshots for checking completion, but the async note already prevents the agent from assuming an immediate result.

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 the parameter meaning is fully carried by the schema. The description does not add detail beyond the schema, but at baseline it is adequate because the schema already explains cubeId, name, and spaceId.

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 uses a specific verb and resource: it creates a snapshot of a Cube's disk. It clearly distinguishes itself from sibling tools like list_snapshots, delete_snapshot, and restore_cube by naming the exact 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 states what the tool does but gives no guidance on when to use it versus alternatives. It does not mention related snapshot tools such as restore_cube or list_snapshots, nor any conditions or prerequisites beyond the schema.

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