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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds no behavioral context of its own: it does not say whether the call is free of side effects, what form the response takes, or whether the content is static marketing copy versus live data.

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?

It is a single compact sentence that front-loads the identity statement and then lists the covered topics with no filler. The telegraphic, comma-spliced list style is slightly awkward but wastes no words.

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 zero-parameter, read-only tool this is close to sufficient since annotations cover the safety profile. However, with no output schema, the description should signal what the caller gets back (a company profile, links, or just prose) and does not.

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; the baseline of 4 applies. The description adds no parameter meaning, which is correct here.

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 enumerates what the tool covers (identity, AI analysis, websites, Agent-Ready, book), so the resource is inferable, but it is a noun-phrase fragment with no verb stating what the tool actually returns. It also fails to differentiate from the sibling 'leistungen_und_preise', which overlaps with 'websites for businesses'.

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?

There is no when-to-use statement, no exclusions, and no reference to any of the siblings such as 'kontakt' or 'analysen'. The agent must guess whether this is an onboarding/background call or a substitute for the services or contact tools.

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