get_v1_media_video_download_by_id

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

With no annotations provided, the description must fully disclose behavioral traits. It states the operation is a GET and that it returns a download link and headers to use. However, it omits crucial details such as authentication requirements, rate limits, the effect of the watermark parameter, error handling (e.g., invalid ID), and whether the action is destructive or reversible.

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 (two sentences) and includes a useful reference link. However, the first sentence is somewhat redundant with the tool name, and the phrase 'by media url' introduces inconsistency. It could be more concise and accurate without losing 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?

Given the absence of an output schema, the description should more thoroughly explain the response format and how to use the returned headers and URL. It only vaguely mentions 'download link and headers' without specifying if the URL is direct or requires authentication. For a download operation, details about redirects, file format, or expiration are missing.

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 50%: only the 'id' parameter has a description (example values). The description does not explain the 'watermark' parameter, its purpose, or its effect on the download. It also fails to clarify the format or constraints of the 'id' beyond the schema pattern. The description adds no additional meaning beyond the schema.

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 it downloads media by ID and provides a download link and headers. The title 'Download Media By Id' and the URL path indicate the specific operation. While siblings exist for music and by-url versions, this tool is clearly for video download by ID. However, the phrase 'by media url' in the second sentence is potentially confusing and slightly detracts from clarity.

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 explicit guidance on when to use this tool versus alternatives like get_v1_media_video_download_by_url or get_v1_media_music_download_by_id. The description does not mention prerequisites, use cases, or exclusions. An agent would have to infer usage from the parameter ('id') and the tool name alone.

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