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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. Because there is no output schema, the description carries the burden of describing what the response contains, and it does so concretely (overall style, daytime/evening rules, formal-night frequency, jeans/shorts/swimwear and venue rules).

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?

A single compact sentence, front-loaded with the resource and followed by the content list. It is a noun fragment rather than a sentence, but every clause maps to actual returned content, so little is wasted.

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 read-only, single-parameter lookup with no output schema, the main risk is the agent not knowing what comes back — the enumeration of returned content addresses that. An explicit statement that only a cruise line name is needed to call it would close the remaining gap.

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% for the single 'line' parameter, including an example ("Royal Caribbean"), so the baseline is 3. The description adds no syntax or format detail beyond what the schema already 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 names the specific resource (a cruise line's dress code) and enumerates its sub-topics — daytime/evening rules, formal nights, venue rules, theme nights — which clearly separates it from getCruiseLineProfile or getShipProfile. It is a content inventory rather than a verb+resource statement, but the resource and scope are unambiguous.

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?

There is no guidance on when to call this versus siblings such as getCruiseLineProfile (which likely also carries line-level policy). No prerequisites, no exclusions, no indication that the caller should already know the cruise line.

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