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

Annotations already cover the safety profile with readOnlyHint=true and destructiveHint=false. The description adds behavioral context beyond annotations: the tool returns a link, pre-fills it from the conversation, and indicates follow-up information. No contradiction with annotations exists.

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 sentence that front-loads the main output ('Geeft de link') and contains no filler. The trailing clause 'en wat er daarna gebeurt' is somewhat vague but the overall structure is compact and scannable.

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?

For a tool with only optional parameters and no output schema, the description says what is returned, that known details are pre-filled, and that follow-up behavior is included. It is reasonably complete, though the exact nature of 'wat er daarna gebeurt' could be more explicit.

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 100%, and each parameter already has a meaningful description in the schema, including notes about values coming from the conversation. The description's 'met de situatie uit het gesprek al ingevuld' largely restates that, so it adds minimal per-parameter semantics.

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 states a concrete deliverable ('Geeft de link') and a specific purpose ('RadioMatic veertien dagen gratis te proberen'), while noting that conversation context is pre-filled. This clearly distinguishes it from sibling tools like bereken_licentiekosten or check_licentieplicht.

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 explicit when-to-use or when-not-to-use guidance, and no sibling alternatives are named. The intended use can be inferred from the purpose, but the description does not help an agent choose between this and related tools such as pakketten_en_prijzen or vergelijk_opties.

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