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

The readOnlyHint=true annotation already declares the safe-read profile, so the bar is lower; the description adds real value by enumerating the data domains returned (pricing/availability settings, channel data, cancellation policy) and mapping to the underlying endpoint GET /api/v3.3/properties/{propertyUid}. It does not mention error behavior for an unknown UID, which is the main remaining gap.

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?

One front-loaded sentence covering the resource and its contents, plus a compact endpoint reference. No filler and no repetition of structured fields.

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?

There is no output schema, and the description compensates by enumerating the returned fields, so an agent knows what to expect from the response. For a single-param read tool this is nearly complete; only error/not-found behavior is 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?

Only one parameter and schema description coverage is 100%, so the schema fully documents property_uid; baseline 3 applies. The description adds no syntax, format, or lookup guidance beyond what the schema and path template already convey.

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 ('Fetch') and resource ('one property's full details') and enumerates the payload contents (address, time zone, rooms, pricing, availability, channel data, booking notes, cancellation policy). This clearly distinguishes it from sibling hostfully_list_properties (many) and hostfully_get_property_calendar (calendar slice).

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?

Usage is implied by the name and the 'one property' scoping versus the list sibling, but the description never states when to prefer this tool over hostfully_list_properties or hostfully_get_property_calendar, nor any prerequisites. Adequate but leaves the routing decision to inference.

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