download_result

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

The description partially discloses behavior: default file selection when file_id is unspecified and the purpose of download_all. However, with no annotations, it lacks information on side effects (e.g., whether downloads are logged) or required permissions.

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 and includes bullet points for parameters, making it easy to scan. It could be more structured with a clear separation of purpose and usage, but the brevity is generally appropriate.

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 the tool has 4 parameters including a required one and an output schema, the description is incomplete. It fails to explain task_id and server, and does not describe return values or error conditions, which an AI agent needs 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 description explains file_id and download_all with useful context (default behavior). However, it omits the required parameter task_id and the optional server parameter, which are in the schema but undocumented, leaving gaps in understanding.

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's purpose: downloading task result files. It mentions specific parameters like file_id and download_all, which helps define the scope. However, it doesn't explicitly distinguish from sibling tools like list_files, which might be a prerequisite.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites (e.g., using list_files to find file IDs) or scenarios where download_all is preferable.

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