download_result

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

No annotations are provided, so the description must carry full burden. It explains the behavior of file_id and download_all, but does not disclose what happens if task_id is invalid, the nature of the download (mutating? read-only?), or any side effects. The server parameter is completely ignored.

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 short but front-loaded with the purpose. The parameter list is bulleted but not all parameters are covered. It is compact but missing important details, making it acceptable but not excellent.

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 that an output schema exists, return values need not be described. However, the description omits the server parameter and provides no context about the task result lifecycle or when to use this tool among siblings. Incomplete for a tool with 4 parameters and no annotations.

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%, meaning no descriptions in schema. The description explains file_id and download_all with some semantics, but ignores task_id (required) and server entirely. Partial coverage with minimal detail.

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 'download task result file', which is a specific verb+resource. It distinguishes from siblings like list_files (listing) and submit_task (submission). However, it does not explicitly differentiate from other download tools, but the purpose is unambiguous.

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?

No guidance on when to use this tool vs alternatives. Siblings include list_files, get_task, etc., but the description provides no context about prerequisites, file availability, or when to prefer this over other tools.

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