iaas_get_disk_snapshots

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. Beyond that the description adds nothing: no indication that this returns a collection, no pagination or result-size behavior, no note that the disk must exist or which permissions are required.

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?

Two short lines with the purpose front-loaded and no filler. The verbatim REST path is mildly redundant with the title but is compact and informative for an API-aware agent.

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?

With annotations present and both parameters fully described in schema, the essentials are covered. However, there is no output schema and the description never indicates that the result is a list of snapshot objects, leaving the agent to guess at the return shape.

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 coverage is 100% and the id parameter is documented as the disk ID with the apiVersion description pointing at /iaas/api/about. The description only echoes the {id} path parameter and adds no format or acquisition guidance, 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 names a specific verb and resource (get disk snapshots) and the embedded endpoint path confirms the scope is a block device's snapshot collection. The plural-vs-singular distinction from the sibling iaas_get_disk_snapshot is left implicit rather than stated.

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 explicit when-to-use guidance and no mention of alternatives such as iaas_get_disk_snapshot for a single snapshot or iaas_get_block_devices for discovering the required disk ID. Usage can only be inferred from the {id} path fragment.

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