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

Annotations already establish read-only, idempotent, non-destructive behavior. The description adds meaningful context beyond those annotations: the quote includes cleaning, fees, taxes, a refundable deposit hold, cancellation/check-in terms, and delegates booking completion to Luxury Lodging's site. It also cautions against promising refunds or quoting nightly rates alone.

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?

The description is compact and every sentence earns its place: what the price includes, what the return value enables, and how the agent should report the result. It is front-loaded with the core purpose and uses no filler.

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 no output schema, the description adequately covers both the return value and agent behavior: the quote composition, the booking_url, and the refund/display constraints. Combined with the rich annotations, an agent has enough to select and invoke the tool correctly.

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?

The input schema already provides descriptions for all five parameters, so the description does not need to repeat or enrich them. It reinforces one property/one stay semantics but adds nothing specific about parameter formats or constraints beyond the schema.

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 clearly identifies the tool as producing a live total price for one property and one stay, including fees, taxes, deposit hold, and booking terms. It also distinguishes itself from sibling tools by emphasizing the single-property/single-stay scope and the booking_url it returns.

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 intended use case is clear: use this tool when the agent needs a complete quoted total for a specific property and date range. It does not explicitly name sibling tools or state when not to use it, so it misses the explicit exclusion guidance needed for a 5.

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