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 fully covered. The description adds only that the corpus is the approved/released KB and that results are relevance-sorted; return format details (source, article ID) are largely redundant given an output schema exists.

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 packs verb, resource, scope, result shape and sort order with no filler. Slightly dense but nothing wasteful; it could have used a second short sentence for sibling routing without harming brevity.

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 rich annotations, a complete output schema and 100% parameter description coverage, the description only needs to convey purpose and result character, which it does. The one gap is the absence of routing guidance against five closely related sibling tools.

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% and every parameter (query, limit, category, language) carries its own schema description, including defaults and enum values. The description adds no additional parameter meaning such as query syntax, category semantics or language fallback behavior, so the baseline 3 applies.

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 (durchsucht) and resource (freigegebene Vetofix-Wissensbasis) and enumerates the content types covered (FAQ, Funktionen, Grenzen), so an agent knows it is a broad KB search. It does not, however, explicitly differentiate itself from siblings like get_faq or get_product_feature, which look like targeted single-type lookups.

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 only implied: by naming FAQ, features and limitations as covered, the description hints this is a superset search rather than a targeted fetch. There is no explicit when-to-use statement or guidance on choosing it over get_faq, get_product_feature, get_troubleshooting_guide or get_current_limitations.

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