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

No annotations exist, so the description carries the full burden. It does disclose useful behavior: the response is bounded to the first 20 preview rows, and "Read" implies a non-mutating operation. It does not mention authentication expectations for private datasets, pagination, or error behavior, which are left to the schema's token description.

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 sentence that front-loads the action and then lists the returned components in priority order. Every clause carries information; nothing is padding.

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 no output schema, the description usefully compensates by enumerating the return contents, including the preview row cap. For a low-complexity read tool with three fully described parameters, this is nearly sufficient, though it omits any note about permissions or large-dataset behavior.

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%, so token, dataset, and version are already documented in the schema. The description adds no parameter-level detail (e.g., what version omits to by default), so the baseline of 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?

The description pairs a specific verb ("Read") with a resource ("a dataset") and enumerates the payload it returns: meta, versions, findings, columns, and a 20-row preview. This implicitly separates it from list_datasets and delete_dataset, but it never names or contrasts a sibling explicitly.

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?

There is no statement of when to reach for this tool versus list_datasets or get_limits, and no prerequisites or exclusions are given. An agent can infer it fetches one dataset's details, but the description offers no routing guidance at all.

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