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

No annotations are provided, so the description carries the transparency burden. It discloses that the tool returns a spread of items across categories and includes prices, and the examples show it handles fuzzy, category/budget-oriented requests. It does not mention side effects, but this is an obviously read-only recommendation action, so the omission is minor.

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 compact sentences: the first states the output nature and content, the second gives the precise trigger condition with illustrative examples. There is no filler, no repetition of the schema, and the key usage signal is front-loaded.

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 one-parameter recommendation tool with no output schema, the description provides enough to decide when to call it and what kind of result to expect. It could be slightly stronger by naming the sibling to prefer when a product is actually named, but that is inferable from the trigger condition.

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%: the single limit parameter is fully documented in the input schema ('1-50, default 20'). The tool description adds no parameter-level meaning beyond that, so the baseline score 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 identifies the resource (products carried by Israeli businesses on AgentFeed) and the nature of the result (a broad, cross-category spread with prices). It distinguishes the tool from exact-match lookup tools by framing it as a response to suggestions without a named product, though it lacks a strong verb and does not explicitly name a sibling.

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?

It explicitly states when to use the tool: when the shopper asks for a suggestion without naming a product, with concrete Hebrew example queries. It does not explicitly name search_products or browse_products as alternatives, but the 'without naming a product' condition clearly routes the agent away from exact-match tools.

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