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

Annotations already declare readOnly, idempotent, and non-destructive. The description adds that it only builds a URL (no content proxying) and conditions on public release status. This is beyond what annotations provide, and no contradiction is present.

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 zero fluff. The core action and condition are front-loaded. Every word earns its place.

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?

An output schema exists, so return values are covered. However, the description omits what to do if the release is not public (e.g., error handling) and does not explain parameter semantics. For a tool with 3 parameters and no schema coverage, more guidance is needed 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?

Schema description coverage is 0%, so the description should clarify the parameters. It mentions 'bounded request URL' but does not explain how count, format, or dataset_id affect the URL. Without this, an agent cannot correctly construct meaningful requests beyond default values.

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 a specific action (build a bounded request URL), the resource (dataset sample link), and a key condition (only when release is public). It also clarifies a non-behavior (does not proxy content), distinguishing it clearly from siblings like describe_dataset or search_datasets.

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?

Provides clear context for when to use: only when the canonical catalog marks the release public. It also gives an exclusion (does not proxy dataset content), implying it's not for fetching content. It doesn't name alternatives explicitly, but the condition is actionable.

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