C2.9/5.0
Behavior3/5

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 only the HTTP endpoint, and does not say what happens to the snapshot's data, whether it's permanent, or permission requirements — leaving the added value modest but not wrong.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The opening two lines are near-duplicates, and 'Second day delete snapshot operation' is a confusing, non-earning sentence. The useful content (the DELETE route) is buried at the end rather than front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive delete with no output schema, annotations do cover the safety profile and the schema is complete, so an agent can invoke it. Still, the description contributes little about consequences or prerequisites beyond what structured fields already provide.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both path parameters (block device id and snapshot id1) and the optional apiVersion are already documented. The description adds no additional parameter guidance, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb (Delete) and resource (Block device snapshot) and confirms the route DELETE /iaas/api/block-devices/{id}/snapshots/{id1}, which clearly separates it from siblings like iaas_delete_block_device and iaas_delete_machine_snapshot. However, it never explicitly names those sibling alternatives, and the 'Second day delete snapshot operation' line is redundant rather than clarifying.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this versus the similar iaas_delete_block_device, iaas_delete_machine_snapshot, or snapshot-revert tools. The name implies a delete-of-a-snapshot, but the description offers no prerequisites (snapshot must exist/exist in a certain state) or exclusions.

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