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

With no annotations, the description carries the full burden, and it does disclose the important traits: the request leaves the system to a human team, the answer arrives asynchronously by e-mail, and consent is mandatory before sending. It does not say what the tool returns at call time (confirmation, ticket id, nothing), whether repeated submissions are deduplicated, or what happens if the team cannot answer — gaps that matter for a 12-parameter outbound escalation.

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 sentences, purpose front-loaded, with the subject matter before the consent constraint and the reply channel. No filler and nothing buried.

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 12 parameters, no annotations and no output schema, the description covers the what, the when and the reply mechanism, but leaves the return value entirely unexplained — the agent cannot tell whether a successful call produces a reference number to relay or simply nothing until the e-mail arrives.

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 92%, so the parameters are already well documented and the baseline applies. The description maps loosely onto 'freigabe' (consent), 'anliegen' and 'naechster_schritt' (what the request is about), but adds no format, ordering or default guidance beyond what the schema already says.

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 action — handing a buyer's request to the vareen.net team — and scopes it to binding information on prices, quotes, contracts and commitments. That is a clear verb+resource pairing an agent can act on. It never names the sibling 'frage', so the boundary between an ordinary question and a binding sales escalation must be inferred from the phrase 'binding information'.

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?

It gives the selecting condition ('binding information on prices, quotes, contracts or individual commitments') and an explicit precondition ('Only use with the buyer's consent'). What it omits is the negative case: nothing says non-binding or general questions should go to 'frage' instead, so the agent is not explicitly routed away from this tool.

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