knmi_search_datasets

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is clear. Description adds the authentication requirement (API key), which is useful. No other behavioral details (rate limits, error handling) are mentioned.

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?

Two sentences with no wasted words. Front-loaded: first sentence states purpose, second adds prerequisite. Efficient and clear.

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 no output schema and many sibling tools, the description does not explain what the search returns (e.g., list of dataset IDs, metadata). Lacks context for integrating results with other tools like knmi_datasets or knmi_latest_files.

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?

Single parameter 'query' has 0% schema description coverage. Description says 'by keyword' which provides basic semantics but lacks format constraints, allowed values, or examples. The description partially compensates but is insufficient.

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?

Clear verb 'Search' and resource 'KNMI weather datasets'. Distinguishes from sibling tools like knmi_datasets (which likely lists all datasets) and knmi_earthquakes by specifying keyword-based search.

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?

States requirement for KNMI_API_KEY but provides no guidance on when to use this tool versus alternatives (e.g., knmi_datasets or knmi_latest_observations). No when-not-to-use or context for selection.

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