List NHS Datasets

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

With no annotations provided, the description carries the burden of disclosing behavior. It explicitly states the return contents and the filtering behavior (matching title or description), which is useful. However, it omits details like pagination, ordering, or case sensitivity, leaving some behavioral aspects untold.

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 two sentences, starts with the core purpose, then lists return fields, then describes the optional filter. Every sentence carries useful information with no wasted 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?

Despite lacking an output schema, the description explicitly names the return fields, which is sufficient for a simple listing tool. With only one optional parameter and a straightforward purpose, the description covers the essential context for correct invocation.

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 already provides 100% coverage for the 'search_query' parameter, including the note that it filters by title or description. The description adds examples ('prescribing', 'dental') but otherwise repeats the schema. Baseline for high coverage is 3, and the examples provide marginal added value.

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 clearly states the tool lists all available datasets on the NHSBSA Open Data Portal and specifies what it returns (names, descriptions, resource counts). This is a specific verb+resource+scope. However, it does not explicitly differentiate from sibling tools like datasets_metadata or datasets_query, though the listing purpose is distinct.

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 for listing datasets with optional filtering by search term, but it does not provide explicit guidance on when to choose this tool over siblings such as datasets_metadata or datasets_query. There are no exclusions or alternative recommendations, making the usage context adequate but not fully explicit.

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