download_dataset

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Download dataset files' and does not explain side effects such as where files are written, whether unzip is applied, overwrite behavior, or authentication/access requirements.

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 extremely terse, but the brevity is not a virtue because it omits all operational detail. A sentence that only restates the tool's basic action does not earn its place as the sole source of guidance for a four-parameter download operation.

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 four parameters, no annotations, no output schema, and 0% schema description coverage, this description is far from complete. An agent has no way to correctly construct inputs, understand return behavior, or avoid misusing the tool.

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?

All four parameter descriptions in the schema are empty (0% coverage), and the tool description provides no parameter meanings. The agent cannot infer what 'ref' should contain or how 'unzip', 'file_name', and 'output_dir' affect the download.

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 clear action ('Download') and a resource ('dataset files'), so the agent knows the basic operation. However, it does not differentiate from sibling tools such as download_competition_data or download_model_version beyond the tool name.

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 guidance on when to use this tool versus alternatives like list_dataset_files, download_competition_data, or download_model_version. No context is given about prerequisites, typical use cases, or when not to use it.

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