get_stock

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

With no annotations, the description carries the full burden, and it does disclose one meaningful behavioral trait: the result is a single page, suggesting pagination. 'GET' also implies a read-only operation. However, it does not mention response shape, continuation-token behavior, required permissions, or any side effects, so behavioral transparency remains limited.

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 terse sentence with no repetition or filler, and the key idea is front-loaded. It is arguably under-specified, but as a concise statement of the operation and pagination behavior, it earns its place without waste.

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?

There are no annotations, no output schema, and three parameters with zero schema description coverage. The description only gives the endpoint and pagination hint, leaving return values, parameter meanings, and pagination mechanics undocumented. This is far from complete for an AI agent deciding how to call the tool.

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%, and the description provides no explanation of the three parameters: size, token, and product_sids. It does not even hint at how pagination or filtering works, so an agent cannot infer parameter semantics without external knowledge.

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 identifies the exact resource and operation: GET /catalog/stock, with the added detail that it returns one page. This clearly distinguishes it from mutation siblings like update_stock or get_consignment_stock by endpoint. It could be clearer about what 'stock' data actually contains, but the core purpose is not ambiguous.

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 versus alternatives such as get_consignment_stock, update_stock, or list_products. The word 'GET' implies a read operation, but no explicit selection criteria, prerequisites, or exclusion conditions are stated.

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