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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered elsewhere. The description adds a useful nuance with 'Kein Versand' (nothing is dispatched/submitted), clarifying this call has no side effects, but says nothing about freshness of pricing or return format.

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 that enumerates the returned content and closes with the no-side-effect qualifier. Dense and waste-free, though the trailing 'Kein Versand' is terse enough to be slightly ambiguous without the annotations.

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 input parameters and no output schema, the description carries the burden of saying what comes back, and it does list the returned categories (packages, prices, services, prerequisites). Only the absence of any output/pagination detail keeps it from a 5.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. No parameter syntax is needed or missing.

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 concrete resource being retrieved — packages, prices, services and prerequisites for a dating photo shoot inquiry in Frankfurt — which is far more than a restatement of the tool name. It does not explicitly contrast itself with the sibling tools (prepare/submit_shooting_inquiry, get_inquiry_status), so it stops short of a 5.

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 rather than stated: pitching the content as material for a 'unverbindliche' (non-binding) inquiry signals this is the read-before-you-act step. There is no explicit when-to-use/when-not or pointer to prepare_shooting_inquiry as the next tool, so it is only an implicit guide.

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