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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so safety and repeatability are covered without the description's help. The phrase 'the questions food businesses ask most' hints that the content is a curated subset rather than an exhaustive FAQ, which is mild added value, but nothing is said about freshness, whether the same call always returns the same set, or what form the answers take.

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?

A single front-loaded sentence with no filler; the scope constraint appears immediately. It loses a point only because it is a noun phrase with no verb, which reads slightly less directly as an action statement than a 'Returns X for a region' phrasing would.

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?

The tool has one fully documented required enum parameter, a strong annotation set, and no output schema, so the remaining burden is to convey what kind of content comes back — which the description does by saying it is questions paired with answers. It stops short of saying whether the answer set is stable or region-complete, a small gap given the tool's simplicity.

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%: the region enum documents all three values, spells out the countries each covers, and even points to find_foodly_region for country mapping. The description only reinforces the one-region-per-call framing ('in one region'), adding nothing about region selection beyond the schema, so the baseline of 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?

The description names a specific resource (the most-asked questions food businesses have about Foodly) with an explicit scope ('in one region') and states that answers are included. It is not a tautology of the name and is distinguishable in substance from get_foodly_plans or get_foodly_start, though it never names those siblings to make the contrast explicit.

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?

There is no when-to-use guidance, no exclusion of cases better served by get_foodly_overview or get_foodly_plans, and no prerequisites stated. The only routing hint ('Use find_foodly_region to map a country') lives in the schema's region property, not in the description, so the description itself carries no usage advice.

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