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

readOnlyHint=true already tells the agent this is a safe read, so the description's main added value is disclosing the payload contents (price, min stay, availability per date). It says nothing about pagination, response size, date-range limits, or auth requirements, which is a moderate gap for a read tool with annotations covering safety.

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 short sentences, front-loaded with the returned data rather than the HTTP verb, and the endpoint reference is a useful tail rather than a lead. Phrasing is slightly convoluted ('the ... set for each date of one property over a range') but wastes no space.

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 three required params, full schema coverage, and no output schema, the description partially compensates by naming the returned fields. It still omits response shape and pagination behavior, but for a simple range read it is close to sufficient.

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 100%, so property_uid, from and to are already documented with their YYYY-MM-DD formats. The description reinforces that the range is per-property but adds no format, ordering, or boundary semantics beyond the schema — 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 resource (pricing periods) and enumerates the returned fields — nightly price, minimum stay, check-in/check-out availability — scoped to one property over a date range. Clear enough to distinguish from list_* siblings, though it does not explicitly contrast with the nearest sibling hostfully_get_property_calendar.

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?

No when-to-use guidance, no exclusions, and no routing to alternatives such as hostfully_calculate_quote or hostfully_get_property_calendar. The date-range scope is implied by the description but not framed as a usage condition.

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