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

Annotations already declare readOnlyHint=true and idempotentHint=true, covering the safety profile. The description adds no further behavioral details such as output format, pagination, or limitations, so it adds little beyond the annotations.

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 a single sentence but somewhat convoluted, mixing multiple clauses without clear front-loading. It is not overly long but could be structured more clearly to highlight the primary purpose.

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?

Given the tool is read-only with a single optional parameter, the description covers the main content: providers, questions to ask, and references to specific providers. It doesn't explicitly state the output format, but for an overview tool this may be sufficient.

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 schema fully documents the 'taal' parameter with an enum and default, so schema coverage is 100%. The description does not add any additional semantics about the parameter, so the baseline score of 3 is appropriate.

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 the tool provides an overview of business music providers, including questions to ask and pointers to specific providers. It distinguishes itself from siblings like 'pakketten_en_prijzen' and 'vergelijk_opties' by focusing on the provider list itself, though the phrasing is slightly convoluted.

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?

No explicit guidance on when to use this tool versus alternatives such as 'vergelijk_opties' or 'muziekadvies_voor_zaak'. The description only states what the tool does, leaving the agent to infer appropriate usage context.

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