get_inventory_record

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It implies a read-only operation but doesn't state so explicitly. It also doesn't mention error behavior, rate limits, or consequences. The listing of returned fields is some help, but it lacks explicit behavioral disclosure.

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?

One sentence, front-loaded with the verb 'Return', lists the returned fields. Highly efficient and easy to scan.

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 simple single-parameter lookup tool with no output schema, the description is fairly complete: it states the action, the input, and the contents of the return value. It could mention error behavior or alternative tools, but for its complexity it's probably adequate.

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 coverage is 0% (the description adds no parameter-level details). The description mentions 'for a SKU' but doesn't explain format, requiredness, or how it maps to the schema. It adds minimal meaning beyond showing the parameter name in context.

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 states a specific action ('Return the full inventory record') and the resource (SKU), and lists the fields included. It is clear and unambiguous, though it does not explicitly distinguish this from sibling tools like lookup_inventory or get_inventory_status. The verb+resource is specific enough to convey the primary purpose, but lacks explicit sibling differentiation.

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?

No guidance on when to use this tool versus alternatives like lookup_inventory or get_inventory_status. The description does not mention scenarios, prerequisites, or why one would choose this over others.

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