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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful return content (room details, facilities, WiFi download/upload and jitter) but does not disclose operational behavior such as rate limits, authentication needs, or error handling.

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 sentences, front-loaded with the core purpose and scope. The second sentence slightly restates that facilities are returned, but overall it is efficient and well-structured.

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?

No output schema exists, so the description carries the burden of describing return values; it does so at a high level (room details, all facilities, network performance data, WiFi metrics). It is sufficient for a simple read tool, though it could specify the return shape more concretely.

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 100% and the single parameter roomId is fully documented in the schema as the unique identifier (tbStaysRoom.EntryID). The description adds no further semantic detail about the parameter, so baseline 3 applies.

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 ('Get') and resource ('facilities and amenities') scoped to 'a specific room', and explicitly includes WiFi metrics. This differentiates it from sibling getAllAmenities (which lacks room scope) and getMyStayFacilities (which is stay-scoped rather than room-scoped).

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?

Provides an implicit usage condition ('for a specific room'), but does not state when to prefer it over getAllAmenities, getRoomFacilityOptions, or getMyStayFacilities, nor any prerequisites. No explicit when-not guidance.

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