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

Annotations already mark the tool as read-only and open-world, and the description adds that it returns category metadata plus paged products by slug. It does not describe quirks such as default sorting, pagination limits, or locale-dependent output, though some of that is covered by parameter descriptions.

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 concise sentence conveys the core behavior with no filler. The main output fields are front-loaded, though the phrasing is slightly awkward with 'by category slug' placed at the end.

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 simple read-only lookup with well-documented parameters, the description is adequate but minimal. It does not explain the shape of the product pages or provide usage context, and there is no output schema to compensate.

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 the parameters are already well documented. The description only reinforces the slug-based lookup and the paged nature of products, adding no substantial meaning beyond the schema.

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 the resource (a category) and the returned content (name, description, and paged products), keyed by category slug. It is identifiable as a single-category lookup and implicitly distinct from list-only or product-only siblings, though it does not name an alternative.

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 guidance is given about when to choose this tool over siblings like list_categories, get_products, or get_brand_products. The slug is mentioned, but the requirement to first obtain it from list_categories appears only in the schema, not in the description.

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