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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without prose. The description adds value by naming the returned fields (price range, stock, product page URL), but says nothing about pagination behavior or result-size limits even though page and page_size exist.

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; the scoping parameter and the returned fields both appear immediately.

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 does describe the shape of results at a high level, which is helpful. It remains incomplete for a paginated browse endpoint: nothing tells the agent that results are paged, how large pages are, or whether more pages may exist.

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 the description must carry parameter meaning. It clarifies the slug's origin (list_categories) well, but leaves page and page_size — the parameters that govern a 50-page browse — completely undocumented in both schema and description.

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 the specific resource ('Products in one category') and even identifies the field that scopes it ('slug from list_categories'), which lets an agent distinguish this from a general search tool. The verb is only implicit ('browse' from the title), so it falls just short of a fully self-contained purpose statement.

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?

It gives a useful chaining hint that the slug must come from list_categories, which implies the correct call order. However, it never says when to prefer this over search_products or get_product, and gives no prerequisites or exclusions.

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