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

With no annotations, the description carries the full behavioral burden. It usefully discloses gateway-based credentials, charges/authorization, attribution requirements, and that a page key is returned, but it does not describe result format, rate limits, or other operational details beyond that.

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 purpose is front-loaded in the first sentence, followed by workflow, attribution, and gateway context. The sentences are generally efficient, though the licensing and gateway details are somewhat tangential to tool selection.

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 two-parameter search tool with no output schema, the description covers purpose, a next-step workflow, attribution requirements, and gateway billing context. It does not fully describe return shape, but the mention of a returned page key gives the agent enough to proceed.

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 both q and limit are already well documented in the schema. The description adds no parameter-level meaning beyond what the schema provides, making the baseline score appropriate.

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 a specific verb and resource: searching Chinese Wikivoyage for destinations and travel guides. The word 'Chinese' helps distinguish it from the broader wikivoyage_get_search sibling, but it does not explicitly name or contrast the sibling guide-retrieval tools.

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 gives an implied usage context and a useful next step: use the returned page key to retrieve a guide. However, it does not state when to use this tool instead of wikivoyage_get_search or the guide-title siblings, nor does it provide exclusions.

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