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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so the safety profile is covered and the mutating-sounding name is not a contradiction — the tool only assembles a URL. Beyond that, the description adds real value: it discloses that the returned link leads to a generator where theme, colors, logo and QR are configurable and print-ready PDF/PNG/SVG can be downloaded, which tells the agent this is a link-builder rather than a document creator.

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 compact sentences: the first front-loads what the tool produces and the downstream capabilities, the second states the data-entry rule. No filler, no restatement of the title, and the most decision-relevant facts come first.

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 five parameters, full schema coverage and no output schema, the remaining burden on the description is to explain what comes back — and it does, describing the filled link and the downloadable PDF/PNG/SVG artifacts. Nothing an agent needs in order to call it correctly is missing.

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%, so every parameter, including the kind enum and the nested section/item fields, is already documented in the schema; the baseline of 3 applies. The description reinforces the sections/items semantics and the no-fabricated-prices rule for the price field, but adds no syntax or format detail 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 names a specific output ("kitöltött link" – a pre-filled link) and a specific resource family (étlap/itallap/napi menü/árlista generator), and lists the supported verticals, so an agent knows exactly what is produced. It does not, however, distinguish itself from near-siblings such as create_document_link or create_graphic_link, which also return generated links.

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 only implied: the description tells the agent what data to supply ("Add meg a szakaszokat és tételeket, amiket a felhasználó elmondott") and adds a hard constraint ("árat ne találj ki" – do not invent prices). There is no explicit statement of when to choose this tool over the link-generator siblings, so the agent must infer routing from the verticals named.

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