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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description earns credit for going further: it discloses that each hit carries a profile link where the inquiry and booking flow happen, and that a no-match response returns a hint plus alternative AI agencies/companies. It stops short of describing result ordering or the exact response shape.

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?

Three tight sentences: the core action and filters come first, followed by what a hit contains and then the no-match behavior. No filler or repetition of the title.

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 output schema, the description correctly explains the return payload (profile link, booking path, fallback agencies), which is the essential missing structure. It is nearly complete, only omitting the undocumented anzahl parameter and result-count/pagination behavior.

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 0%, so the description must do the work, and it explains faehigkeit, stadt and max_stundensatz_eur. However, the fourth parameter (anzahl) is never mentioned, nor are constraints like the 1–20 cap or any default, leaving a real gap.

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 and resource ("Findet buchbare KI-Freelancer") plus the source platform and the three filter axes. The resource (freelancers) is naturally distinct from the sibling tools ki_unternehmen_suchen and ki_tools_suchen, so an agent can route without opening any schema.

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?

The description gives clear context for use — search freelancers by skill, optionally narrowed by city and maximum hourly rate — and even explains the fallback path when nothing matches. It never explicitly names an alternative sibling or states exclusions, which is what separates it from a 5.

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