Behavior2/5

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

No annotations provided, and description only says 'Get detailed information'. Does not disclose safety (read-only), authentication needs, error behavior, or other traits. With zero annotation coverage, description should provide more behavioral context.

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

Conciseness5/5

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

Extremely concise, front-loaded purpose, parameter list with clear one-liners. No unnecessary words.

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

Completeness4/5

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

With an output schema present, the description doesn't need to explain return values. Covers basic usage adequately. Slight gap in error scenarios or prerequisites, but acceptable for an inspect tool.

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

Parameters4/5

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

Adds meaning beyond schema: clarifies endpoint_id as 'Target endpoint ID' and explains default behavior ('uses default if omitted'). For volume_name, only restates schema, but overall improves understanding. Schema coverage is 0% so description compensates well.

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

Purpose5/5

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

Clearly states 'Get detailed information about a Docker volume' with a specific verb and resource. Distinguishes from sibling tools like volume_create, volume_remove, and volumes_list.

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

Usage Guidelines3/5

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

Implied usage for inspecting volume details, but no explicit when-to-use, when-not-to-use, or alternative tool guidance. Siblings include inspect for other resources, but no differentiation mentioned.

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