TDQS

A3.5/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety bar is low. The description nonetheless adds real behavioral value beyond them: the pricing is "current published" (not a snapshot of historical or negotiated rates) and is explicitly non-binding until a quote or hold is issued, which is exactly the caveat an agent needs before quoting numbers to a user.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero filler, with the returned dimensions front-loaded and the caveat placed last where it reads as a qualifier rather than a distraction. Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists and annotations fully cover the safety profile, so return-value and permission explanation are correctly omitted. However, with a localized pricing tool the total silence on locale and on what a rentalId refers to leaves a gap the description should have closed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% for both parameters, so the description carries the full burden and fails it: rentalId (required) is never mentioned, and the locale enum with its "de" default is completely unexplained — an agent cannot tell from this text that pricing output is localized or that locale is even an accepted input.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb (Return) plus resource (current published monthly pricing) with the full set of dimensions covered: duration, parking, deposit, inclusions, payment method, minimum-stay terms. It implicitly separates itself from quote-issuing siblings by noting pricing is informational until a quote or hold exists, though it never names quotes.create/quotes.get directly, so it falls short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

"Pricing is informational until a quote or hold is issued" hints that this is the browse-before-committing tool and that quotes.create is the next step, but it never states an explicit when-to-use rule or names the alternative tool. Usage is implied rather than prescribed.

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