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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses cost ('1 point per returned record') and the returned fields, but does not cover auth requirements, rate limits, pagination behavior, or error handling.

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 two short sentences with no waste: the first states what is returned, and the second states the cost. It is front-loaded and appropriately sized for a simple lookup tool.

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?

Given a simple three-parameter tool with full schema coverage and no output schema, the description is nearly complete: it lists returned fields and mentions cost. It lacks sibling routing guidance, but the schema and title cover the remaining structural 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 description coverage is 100%, so the schema already documents seller, max_items, and start_page. The description mentions seller ID or store URL but adds no syntax, constraints, or meaning beyond what the schema provides.

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 specific resource and scope: a seller's storefront products on Trendyol, retrievable by seller ID or store URL, and lists returned fields. It does not explicitly contrast with nearby siblings such as run_trendyol_products or run_trendyol_products_sellers, so sibling differentiation is left to the reader.

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 no when-to-use guidance, no exclusions, and does not name alternatives. It implies usage only through the required seller parameter, leaving the agent to infer the routing context from the title and name.

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