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

Annotations already declare read-only, idempotent, non-destructive and closed-world behavior, so the safety profile is covered. The description adds genuinely new context beyond that: it returns a URL artifact rather than data, and it explicitly does not collect email, which is a meaningful privacy trait an agent would not otherwise know. It still omits link permanence or auth requirements, so not a 5.

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 tight sentences with no filler; the core capability (returns a watch URL) is front-loaded and the caveat follows. Every sentence earns its place.

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 one-parameter tool with no output schema, the description adequately describes the return artifact (a URL) but leaves gaps: the resort identifier format is unexplained and the mention of dates has no corresponding schema field. Adequate but with clear omissions.

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 0% and the single 'resort' parameter has no description, so the description carries the full burden. It never explains the expected format (name, slug, or ID) for 'resort', and it mentions 'optionally add dates' even though no date parameter exists in the schema, which makes the parameter story less clear rather than more.

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 uses a specific verb+resource: it returns a one-tap URL where a person can watch a resort. It also states the scope constraint that dates are optional. It doesn't name or contrast a sibling (e.g. get_webcams), so it stops short of 5.

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 explicit when-to-use guidance or comparison to alternatives such as get_webcams or get_resort_media. The use case is only implied by the phrase 'where the person can watch a resort', leaving the agent to infer when this tool is preferred.

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