get_file_download_url

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

No annotations are present, so the description carries the behavioral burden. It discloses the key trait that the URL is temporary and points to the original file, implying a read-only, expiring URL. But it omits details such as URL expiration length, authentication requirements, or failure cases.

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 a single sentence with no wasted words. It front-loads the action and resource, and every remaining word adds meaning.

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?

Adequate for a simple two-parameter URL fetch tool, but incomplete for an unannotated tool with no output schema. It lacks explicit alternative routing, expiry behavior, and any indication of what the caller should do with the returned URL.

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 coverage is 100%, and both parameters are described as UUIDs in the schema. The description adds no per-parameter detail, though 'original file' clarifies why both asset_id and file_id are relevant to obtaining the original-file URL.

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 ('Get'), a specific resource ('temporary download URL'), and the subject ('original file'). The qualifier 'original file' helps distinguish it from sibling tools like get_proxy_download_url and get_keyframe_public_url.

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?

Usage context is implied by 'original file': an agent can infer this is for original files rather than proxies or keyframes. However, it does not explicitly name alternatives or state when not to use this tool, so routing guidance is largely left to inference.

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