iaas_delete_machine_snapshot

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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond restating DELETE: it does not say the snapshot is permanently removed and unrecoverable, whether the machine must be powered off, or whether associated data is affected.

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?

It is short, but the second line ("Second day delete snapshot operation for machine") is a near-duplicate of the first and reads as leftover generated filler. The endpoint is useful and front-loadable, so the waste is modest rather than fatal.

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 destructive, idempotent delete with no output schema and fully documented parameters, the minimum an agent needs is present, and annotations carry the destructive/idempotent signals. However, nothing is said about irreversibility or preconditions, which is a real gap for a destructive tool.

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 id and snapshotId documented as path parameters and apiVersion explained. The description's path template mirrors that but adds no format, validation, or scoping detail, so 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 ("Delete snapshot ... for machine") and includes the exact REST path, so an agent knows precisely which operation this is. It does not differentiate from siblings like iaas_create_machine_snapshot, iaas_revert_machine_snapshot, or iaas_get_machine_snapshot, and the duplicated "Second day" line adds noise but no disambiguation.

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 statement of when to use this tool rather than revert_machine_snapshot or get_machine_snapshots, and no mention of prerequisites such as machine power state or required permissions before a snapshot can be deleted. Usage is only implied by the verb and path.

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