TDQS

C2/5.0
Behavior2/5

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is carried by structured data. The description adds no further context, such as whether the volume's data is irrecoverably lost, whether it can be called on an attached volume, or what a success response looks like.

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?

It is a single short sentence, but the brevity comes from under-specification rather than efficiency: the one sentence duplicates the title and wastes the only slot available for behavior or usage guidance.

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

Completeness2/5

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

For a destructive, irreversible operation with no output schema, an agent needs at minimum a warning about data loss and any attach/prerequisite state. Annotations cover only the generic destructive flag, and the description supplies none of the tool-specific risk information.

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%, including the optional workspace and environment defaulting behavior, so the schema already does the work. The description adds nothing about parameter meaning; baseline 3 applies.

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

Purpose2/5

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

Names a verb+resource (delete, storage volume) but does so as a near-verbatim restatement of the tool name and title, adding no scope detail. There is no differentiation from sibling destructive tools such as delete_instance, delete_instance_link, or delete_schedule.

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

Usage Guidelines1/5

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

Provides no when-to-use guidance, no prerequisites (e.g., volume must be detached), and no reference to alternatives such as delete_instance. An agent learns nothing about the conditions under which this call is appropriate.

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