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

The annotations already establish readOnlyHint, idempotentHint, and openWorldHint=false, so the safety profile is covered. The description adds useful return values, q_b and w with units, but omits assumptions, formula context, and the effect of the region parameter.

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 short and front-loaded, with the result values clearly stated in the final sentence. Minor waste appears in 'einfach online', and the region/title tension is left unaddressed.

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?

Because there is no output schema, the description appropriately names the returned quantities and units. However, it does not reconcile the Swiss SIA 261 framing with the region parameter defaulting to DE, which is a meaningful ambiguity for invocation.

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 100%, so all five parameters and the region enum are already documented in the schema. The description mentions aerodynamic coefficients and dynamic pressure conceptually but adds no parameter-level syntax or default behavior 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?

The description states a specific verb and resource: calculating wind load according to SIA 261 for structures in Switzerland. The domain is clear, though the opaque sibling names bot_009–bot_065 provide no basis for explicit differentiation.

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 says what the tool calculates but gives no when-to-use guidance, no prerequisites, and no alternatives. The phrase 'einfach online' is promotional rather than operational guidance.

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