get_product_group_variant_quantities

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

No annotations are provided, so the description carries the full behavioral burden. It implies a read operation via 'Get' but does not disclose whether quantities are aggregated by location, whether missing variants are omitted or zeroed, or what permissions are needed. For a tool with zero annotation coverage this is a significant 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?

A single front-loaded sentence with no filler. Every word contributes to scoping the operation.

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?

With no annotations, no output schema, and 0% schema description coverage, the description is the only source of meaning and it does not explain what a 'quantity' represents (on-hand, available, committed) or the return shape. It is too thin for the information vacuum surrounding it.

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 0%, so both parameters rely on name alone. The description partially compensates by mapping the concepts 'one product group' and 'one location' to the two required params, but adds no format, ID-type, or scope detail beyond that.

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 verb ('Get') and resource ('product-variant quantities') scoped to one product group and one location. An agent can distinguish this from siblings like get_product, get_product_group, or create_product_group_variants. It lacks explicit sibling differentiation, but the scoping detail makes the purpose unambiguous.

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 on when to use this tool versus alternatives such as get_product_group, get_inventory_summary, or create_product_group_variants. The description implies a read of variant-level quantities but never states prerequisites or exclusion conditions.

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