getCategories

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get list of product categories', which implies a read operation but does not mention authentication, pagination, return format, or any potential side effects. This is minimal and lacks helpful context beyond the verb itself.

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 extremely concise: one sentence, front-loaded with the action and resource, with no wasted words. It is appropriately sized for a tool with no parameters and simple functionality.

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?

The tool is simple (no parameters, no output schema), but the description is minimal. It states the existence of a list but does not elaborate on the structure of categories, whether results are sorted, or any caveats like empty lists. While not inadequate for a basic get-list, it could provide more return-value context to be fully complete.

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 tool has zero parameters, so there is no schema information to augment. The baseline for 0 parameters is 4, and the description adds no unnecessary parameter details, which is appropriate. No additional meaning is needed.

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 verb 'Get' and the resource 'list of product categories'. It is distinct from all sibling tools, which focus on products, variants, files, sync operations, mockup tasks, and stores, making the purpose unambiguous.

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 provided on when to use this tool versus alternatives. The description implies its use when needing product categories, but there is no explicit context or exclusions, such as 'use getCategories for catalog browsing' or 'prefer getProducts for individual items'.

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