list_inventory_levels

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

No annotations are provided, so the description carries full burden. It states it returns available quantities but does not mention pagination behavior, rate limits, or whether it lists all items or only those with stock.

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 two sentences (24 words), concise and front-loaded with the core purpose. No filler or unnecessary detail.

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 output schema, the description vaguely indicates the return format (available quantities per item) but lacks specifics on the structure (e.g., fields like item ID, quantity). Pagination details are also missing, though implied by the page_info parameter.

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 baseline is 3. The tool description does not add additional meaning beyond the schema descriptions for location_id, limit, and page_info.

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 clearly states it lists inventory levels (stock quantities) for a given location and specifies that it returns available quantities per item. It is distinct from sibling tools like list_locations or list_products.

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 implies usage for checking stock quantities at a location but provides no explicit guidance on when to use this tool versus alternatives like adjust_inventory or set_inventory.

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