vinted_catalog

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

The description adds the useful context that this is 'Public data, sourced from Vinted's own server-rendered catalog page', implying safe read-only access and data provenance. However, it doesn't disclose pagination behavior, response structure, or rate limits, which the absence of annotations makes more important.

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 compact and front-loaded, starting with the core purpose in a single sentence. The list of order values is a concise, useful addition, and the sourcing note is brief. No wasteful words or redundant details.

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 description covers the basic search function and filters, but with no output schema, it does not explain what fields are in each returned listing or how pagination works. Given the tool's moderate complexity (5 params), the description is adequate but leaves gaps in expected result details.

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 100% with each parameter documented. The description's mention of 'optional price filtering' and the list of order values matches the schema descriptions but does not add new meaning beyond the structured input schema, so the baseline of 3 applies.

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 states the tool is a 'Vinted listing search' that 'returns Vinted resale listings matching a text search', explicitly naming the action (search) and resource (Vinted resale listings). It clearly distinguishes from sibling tools like vinted_item or vinted_category by focusing on text-based search with filters.

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 implies usage for text-search queries on Vinted and mentions optional price filtering and sorting, but it does not explicitly explain when to choose this over sibling tools like vinted_category or vinted_item, nor does it state any exclusions or alternative recommendations.

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