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

With no annotations, the description carries the full behavioral burden, yet it only discloses the URL's domain. It does not say whether the property must exist, whether a missing/empty check_in/check_out changes the link, whether the link is static or session-generated, or anything about auth or rate limits.

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 short, front-loaded sentence with no filler. It is appropriately sized for the claim it makes, though the terseness borders on under-specification given the undocumented parameters.

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?

An output schema exists, so return values need not be explained, but a three-parameter tool with 0% parameter coverage and no annotations needs far more than one clause. The relationship between the date parameters and the generated URL is entirely unaddressed.

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% across three parameters, so the description must compensate and does not. It only implies the 'property' input via 'for a property' and says nothing about what check_in and check_out do or why they default to empty strings.

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 resource (a booking URL) and its domain (nuvistahaven.com) for a given property, so the agent knows what it returns. It does not, however, distinguish this from the sibling get_quote, which likely also produces a booking-related URL, leaving some ambiguity about when this one is the right choice.

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 offers no when-to-use guidance and names no alternatives among the four siblings (check_availability, get_property_details, get_quote, search_properties). The agent must infer that this is the final 'produce the booking URL' step from the name alone.

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