runninghub_download_file

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

No annotations are provided, so the description carries the full behavioral burden. It does not disclose whether an existing file at savePath is overwritten, whether the parent directory must exist, required auth, or rate/ size limits — all relevant for a file-download mutation.

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 short sentence with the action front-loaded and no wasted wording. It is efficient, though it carries no structural elaboration such as caveats or return behavior.

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?

For a simple 2-parameter tool with no output schema and full schema coverage, the description is barely adequate. It omits the behavioral details (overwrite, directory existence, failure modes) that matter when no annotations exist.

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 both 'url' and 'savePath' are already documented in the schema, including the 'absolute path incl. filename' constraint. The description adds no extra format or semantics beyond that baseline.

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?

States a specific verb (下载/download) and resource (任务结果文件/task result file) plus the destination (本地指定路径). It clearly reads as the counterpart to runninghub_upload_file among the siblings, though it does not explicitly name any sibling.

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 versus alternatives, no prerequisites, and no mention of what must happen first (e.g. that a task must have produced a result URL). Usage is only inferable from the tool name and the '任务结果' qualifier.

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