create_volume

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

No annotations are provided, so the description is the sole source of behavioral disclosure. It only states that a volume is created, without mentioning idempotency, behavior if the volume name already exists, driver implications, label handling, permissions, or side effects. This is a serious gap for a mutating tool.

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 short, front-loaded sentence with no wasted words. However, because it largely restates the tool name and omits useful context, it is under-specified rather than genuinely well-structured.

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 creation tool with one required parameter, an object-typed labels parameter, no output schema, and no annotations, this description is far too sparse. It does not mention required parameters, defaults, expected behavior, or failure modes, so an agent cannot predict the tool's behavior or return value.

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 documents the three parameters and the driver default. The description adds no parameter-level meaning beyond what the schema already provides, so the baseline of 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 'Create a Docker volume' is essentially a grammatical expansion of the tool name create_volume; it adds only the word 'Docker' and no new meaning. It is clear but tautological, and does not differentiate itself beyond the obvious verb from sibling volume tools.

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 guidance about when to use this tool, when not to use it, or which sibling tools might be alternatives (e.g., list_volumes, remove_volume). An agent is left to infer usage solely from the name and schema.

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