create_volume

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

With no annotations provided, the description carries the full burden of behavioral disclosure but fails completely. 'Create a new volume' implies a write/mutation operation but doesn't disclose any behavioral traits: no information about permissions required, whether this is idempotent, what happens on failure, rate limits, or what the tool returns. For a creation tool with 7 parameters, this lack of behavioral context is a critical gap.

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 maximally concise at just three words. While this represents severe under-specification rather than ideal conciseness, from a pure structural perspective, it's front-loaded with the core action and contains zero wasted words. Every word earns its place, even though more words are desperately needed.

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 complexity (7 parameters, creation operation), complete lack of annotations, 0% schema coverage, and no output schema, the description is completely inadequate. It doesn't explain what a volume is, what parameters mean, what happens during creation, what gets returned, or how this differs from sibling tools. For a tool with this level of complexity and zero structured documentation, the description fails to provide even basic contextual understanding.

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?

With 0% schema description coverage for all 7 parameters, the description provides zero parameter semantics. It doesn't explain what 'name', 'size', 'automount', 'format', 'location', 'server', or 'labels' mean, their expected formats, or how they interact. The description fails to compensate for the complete lack of schema documentation, leaving all parameters semantically undefined.

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 'Create a new volume' is essentially a tautology that restates the tool name without adding specificity. It doesn't explain what a 'volume' is in this context (storage volume, network volume, etc.) or what resources it creates. While it includes a verb ('Create') and resource ('volume'), it lacks the specificity needed to distinguish it from sibling tools like 'create_server' or 'create_network'.

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 provides absolutely no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, when this operation is appropriate, what happens after creation, or how it differs from related tools like 'attach_volume' or 'update_volume'. The agent must infer usage entirely from the tool name and schema.

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