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

Annotations already declare readOnlyHint, destructiveHint, and openWorldHint, so the bar is lower. The description adds meaningful behavior: it asks up to three fixed follow-up questions while required information is missing and returns three proposals without prices, appointments, or feasibility commitments. It does not explain the non-idempotent interaction state further.

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 dense German sentence that is front-loaded with the core purpose and then unpacks the process, output, and constraints. All clauses are informative, though the sentence is long and could be split for readability.

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?

There is no output schema, but the description explains that the tool returns a summary with three proposals (small, medium, large) from the service inventory. Annotations cover the safety profile, and the schema documents two of three parameters, so the description is largely complete for this conversational clarification tool.

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 67%, with descriptions for antworten and session_id but none for brief. The description conceptually maps 'freien Kundenwunsch' to brief and 'Rueckfragen' to antworten, but adds no syntax, format, or key details 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?

States a specific verb (Klaert) and resource (freien Kundenwunsch) plus a clear process and output. However, it does not explicitly differentiate from siblings such as flowboxx_frage or flowboxx_anfrage, so an agent must infer the distinction.

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?

Implies usage for a free customer request that needs clarification while mandatory details are missing. It does not state when not to use the tool or name alternative siblings, leaving alternative selection to inference.

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