data_overheid_themes

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

Annotations already declare readOnlyHint and openWorldHint. The description adds the claim of returning 'all' themes, which is a behavioral trait. However, no information about pagination, ordering, or exhaustiveness is provided. The description adds some value beyond annotations but is limited.

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 concise sentence that directly states the tool's purpose. No unnecessary words or information.

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's simplicity (no parameters, read-only, open world), the description is mostly complete. It covers the core purpose. However, since there is no output schema, the description could have provided a hint about the return format (e.g., list of strings or objects). Still, it is adequate for typical use.

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?

There are zero parameters, so the description does not need to add parameter information. The baseline for 0 parameters is 4, and the schema coverage is 100% (empty schema). The description adds no parameter semantics, but none are needed.

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 uses a specific verb ('List') and a clear resource ('all dataset themes/categories'). It uniquely identifies this tool's function among siblings (e.g., data_overheid_datasets_search, data_overheid_organizations), which are focused on searching datasets or retrieving organizations.

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 implies usage as a simple lookup for themes/categories, but it does not explicitly state when to use this tool versus alternatives (e.g., before searching datasets with a theme filter). No exclusions or prerequisites are mentioned.

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