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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=false, covering the safety profile. The description adds important behavioral context beyond annotations: results contain Hebrew editorial copy and page URL by design, no booking link/price, and the agent should not seek the operator. This clarifies expected result content and prevents unnecessary actions.

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?

Three concise sentences with front-loaded action and zero fluff. Every sentence adds value: what it searches, what it returns, and the critical no-booking-link/operator instruction.

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?

With no output schema, the description does explain the key return values (Hebrew editorial copy and page URL) and the absence of booking/price fields. It is complete enough for an agent to invoke and render results, though it does not detail list shape or pagination beyond the schema's limit parameter.

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 q, limit, and category all documented. The description adds no parameter-specific semantics beyond the schema, so the baseline of 3 applies. The only subtle addition is the catalog context, which does not clarify individual parameters.

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 states the tool searches the catalog of day trips and attractions, and specifies what it returns (Hebrew editorial copy and page URL). This distinguishes it from general site search and other sibling tools by resource and content type.

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 when to use this tool (when needing day trips/attractions from the catalog) and adds an explicit 'do not go looking for the operator' instruction. It does not name sibling alternatives or exclusions, so it lacks the explicit when-not-to-use guidance for a perfect score.

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