volume_create

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the operation is a creation ('Create') but does not disclose side effects, idempotency behavior, error conditions, or any permissions. The minimal description leaves the agent without context on what creating a volume might affect.

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 a single, clear sentence with no redundant words. Every part contributes to understanding the tool's purpose, and it is properly front-loaded.

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 nature of the tool and the rich schema, the description is minimally complete. However, it lacks any mention of return value, edge cases (e.g., duplicate names), or behavior when name is omitted, which would be helpful for an agent invoking the tool. The schema covers parameters but not operational context.

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 schema fully describes each parameter. The description itself adds no parameter-specific meaning beyond what the schema already provides, and the baseline of 3 is appropriate.

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 'Create' with a specific resource 'new named volume' and states its purpose ('can be attached to containers'). It clearly distinguishes from sibling tools like volume_list and volume_remove, which are read/delete operations.

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 implies the use case by mentioning volumes are attached to containers, but it does not explicitly state when to choose this over alternatives or mention any prerequisites/exclusions. The guidance is implied rather than explicit.

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