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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds value beyond that by disclosing attribution/licence obligations for returned media and stating the negative fact that no trail-map image is available, which prevents an agent from hunting for one.

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 dense sentence that front-loads the purpose before listing contents, with no filler. It is slightly run-on in the enumeration, but every clause carries distinct information.

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 the work of describing the return payload in detail, including licence and attribution fields, and rules out the trail-map image. The remaining gap is the undocumented input format and no mention of behavior when a resort has no media.

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 0% and the single required 'resort' parameter is undocumented in both schema and description. The description never says whether the value is a name, slug, or ID, nor what happens on an unknown resort, so with a 0% coverage it fails to compensate.

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?

States a specific verb+resource ('Get images for a resort') and then enumerates exactly what comes back: webcams with provider credit, a Wikimedia Commons photo with licence/author/source, the EM Snow teaser, and the resort page link. An agent can distinguish this from get_webcams, which returns camera feeds alone, without opening a schema.

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 phrase 'that vision-capable assistants can show' implies the intended context, but there is no explicit when-to-use guidance, no exclusions, and no pointer to the closely overlapping siblings get_webcams or watch_resort. Usage must be inferred from the content listing.

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