Find a Vinted category

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

Annotations already mark the tool as read-only and open-world, but the description adds valuable context: results are ranked, the response includes id and full path, and the correctness of category selection affects listing visibility. It does not contradict annotations and goes beyond the structured metadata.

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 three sentences, front-loaded with the main action, and every sentence provides meaningful information—what it does, the leaf-category nuance, and a user interaction guideline. No filler or repetitive content.

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 search tool with no output schema, the description sufficiently covers purpose, return value structure, and a critical usage caveat (leaf categories). It lacks detail on ranking criteria or no-result behavior, but given the tool's simplicity and annotation coverage, the description is reasonably 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?

Schema coverage is 67%, covering query and country with examples. The description adds some context by mentioning the full path and leaf category, which helps interpret output but not the limit parameter. Since the schema already documents most parameters, the description provides marginal additional parameter-level 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 clearly identifies the tool as a search over the Vinted catalogue tree that returns ranked candidates with numeric id and full path. It distinguishes itself from sibling tools like find_brand by focusing on categories and adds the leaf-category constraint, making the purpose specific and 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?

The description gives clear context for use: when you need a category for a listing, especially highlighting that only leaf categories can hold listings. It provides a behavioral guideline to show top candidates rather than silently pick the first, but does not explicitly compare against alternative tools or mention when not to use it.

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