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

Annotations already declare read-only, idempotent, closed-world, non-destructive behavior, so the description's job is to add what annotations cannot. It does: the content is 'public' and 'verified' (authoritative rather than user-generated) and the source text is French and may need translation — a genuinely actionable operational note. It stops short of describing structure or whether any proprietary/pricing data is excluded.

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 with no waste, and the payload description is front-loaded. The opening reads as a sentence fragment ('Public verified description, capacity and facilities'), which is slightly awkward but costs no comprehension.

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 carries the burden of saying what comes back, and it enumerates the three content areas plus the language caveat. Missing only scope boundaries such as whether location/contact or pricing details are included, which an agent might otherwise assume.

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?

There are zero parameters and the schema is fully closed (additionalProperties: false), so there is nothing for the description to clarify. Baseline for a no-param tool is 4; the description correctly implies no arguments are needed.

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 names the specific content returned — public verified description, capacity, and facilities of the privatized property near Rouen — which lets an agent distinguish it from siblings like get_quote or check_availability. It is a noun-phrase inventory rather than a verb+resource statement, but the resource and payload are unambiguous.

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?

Usage is implied: this is the general discovery/informational call, and the siblings cover availability, booking options, quotes, stay rules, and dog policy. However, the description never states when to call this first, whether it should precede check_availability or get_quote, or any exclusions.

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