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

No annotations are provided, so the description must explain behavior. It states that this is a catalog and enumerates furniture types, but does not disclose whether it returns a static list, whether images are included, or any other behavioral details beyond the basic catalog concept.

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 with the key concept front-loaded ('Каталог композитной мебели') followed by a helpful list of examples. No filler or redundancy.

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 no-parameter catalog tool, the description is sufficiently complete: it names the domain (pool furniture), material (composite), and examples of included items. Given the absence of an output schema and the simple nature of the tool, little else is necessary.

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?

There are zero parameters, so the schema offers no parameter-level information. The description adds value by enumerating the specific furniture categories (loungers, benches, tabletops, stools, planters), giving the agent and user a clear sense of what the catalog contains.

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 identifies the tool as providing a catalog of composite furniture for pools, listing specific categories (loungers, benches, tabletops, stools, planters). It distinguishes from siblings like get_accessories by focusing on furniture, although it lacks an explicit verb.

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?

Usage is implied: use this tool when the user needs pool furniture items. However, there is no explicit guidance on when to choose this over similar sibling tools like get_accessories or get_pool_specs.

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