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

No annotations are provided, so the description must carry the behavioral disclosure. It gives useful context by stating that the result is an EUR breakdown and enumerates the mandatory and optional components. It does not explicitly mention whether this operation is read-only, non-binding, or has any side effects, though the 'get' prefix strongly implies a calculation-only action. This is an adequate but not comprehensive disclosure.

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 a single, tight sentence that front-loads the key information ('Price breakdown in EUR') and then lists components without redundancy. Every element (nightly rates, cleaning, add-ons) earns its place, and it avoids repeating schema-level details like parameter formats or defaults.

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 provides a broad sense of what is returned: a breakdown with the main pricing components. It does not cover error handling, quote validity, or the exact return data structure, but these are not usually required for a simple quote tool. The key purpose and the influencing parameters are described, so the definition is nearly complete.

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 low (33%), and the description helps by tying `bed_linens` and `hot_tub` to their pricing, mentioning the one-time dog fee for `number_of_dogs`, and saying nightly rates are date-dependent to imply `check_in`/`check_out` meaning. It does not fully clarify how `number_of_guests` affects price beyond the per-person linens, so the added meaning is partial but valuable.

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 states the tool returns a price breakdown in EUR for a stay, with nightly rates, cleaning fee, and optional add-ons. It is distinct from siblings because it addresses pricing, while `check_availability` deals with date availability, `get_property_info` with property details, and `submit_booking_request` with booking. However, it lacks an explicit verb ('get' is only in the title), so it doesn't fully meet the 'specific verb' criterion.

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 implies this is the tool to call when a price estimate for a stay is needed, since it describes the decomposition of the quote. It does not explicitly say when to use it versus the siblings, nor does it state conditions like 'do not use this to book'. The implied context and the sibling names convey enough, but the guidance is not made explicit.

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