label_products

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

With no annotations, the description carries the full burden and only discloses that results are paginated and include pricing. It says nothing about auth requirements, behaviour for an unknown slug, default page size, or total-count semantics — all relevant for a listing endpoint.

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 single fragment has zero wasted words, but it is under-specified rather than concise — it reads like a subtitle, not an instruction. There is no front-loaded verb or structural separation of purpose versus behaviour.

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 five-parameter listing tool with no annotations and no schema descriptions, an output schema only relieves the need to document return values. An agent still lacks the slug semantics, sorting behaviour, and usage context needed to call this confidently.

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% across five parameters, so the description should compensate and does not. "Paginated" vaguely gestures at limit/offset, but slug, sort, and direction (including the asc/desc convention) remain completely undefined.

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?

"Products carrying a label" essentially restates the tool name label_products; there is no verb (list/retrieve) and no differentiation from the sibling label_detail. The phrase "priced and paginated" adds a hint about the result set but not a distinct purpose.

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 when-to-use guidance is given and no alternative is named, even though siblings like category_products, new_products, brand_products, and label_detail clearly overlap. The agent must guess whether this is the right tool for browsing by label.

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