Get category

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

The description aligns with the readOnlyHint annotation (a read operation). It does not add extra behavioral context such as error handling or response format, but for a simple getter, the annotation already covers the key safety trait. No contradiction, but no additional disclosure beyond the annotation.

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, concise sentence that is front-loaded with the verb and resource. It conveys all necessary purpose without extra words.

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 getter with one parameter and no output schema, the description is adequately complete. It implicitly indicates the return is the category object. It could mention not-found behavior, but this is a minor gap given the tool's simplicity and annotations.

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?

The input schema covers the only parameter 'id' with a description ('Category ID (UUID)') at 100% coverage. The description's 'by its ID' adds no new semantics. Baseline 3 is appropriate since the schema fully handles parameter meaning.

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 'Get a single product category by its ID' uses a specific verb and resource, clearly distinguishing it from list_categories (which retrieves multiple) and create/update actions. It precisely states what the tool does.

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 usage is implied: retrieve a category when you have its ID. However, there is no explicit mention of when to use this over list_categories or any alternative. The context is clear but not explicitly differentiated from siblings.

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