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

With no annotations, the description carries the full burden. It does add one genuinely useful behavioral fact – the cost model ('1 point per returned record') – and lists the returned fields, but it says nothing about pagination behavior, rate limits, or failure modes when the ePID is invalid.

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?

Two tight sentences with zero waste; the identity and scope come first, and the cost note is a single appended clause that earns its place.

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?

There is no output schema, so naming the returned fields (rating, text, author) is a real contribution, and the cost line covers a behavioral gap. What remains thin is pagination/limit behavior, which the schema only implies via max_items and start_page.

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 product, max_items, and start_page. The description reinforces that 'product' accepts an ePID but adds no syntax, format, or constraint detail beyond the schema. Baseline 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?

Specific verb (Get) plus resource (buyer reviews) scoped to an eBay catalog product by ePID, and it names the returned fields. This distinguishes it in spirit from run_ebay_seller_feedback and run_ebay_product, though it never explicitly contrasts itself with those siblings.

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 states what the tool does but gives no when-to-use guidance, no prerequisites, and no mention of the adjacent eBay tools (run_ebay_product, run_ebay_seller_feedback) an agent might confuse it with. Usage is only inferable from the name.

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