get_v1_media_video_download_by_url

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

No annotations provided, so description must disclose behaviors. It mentions response contents (download link and headers) but omits behavioral traits like read-only nature, authentication, rate limits, or any side effects.

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 brief (two sentences plus a bracketed header) but the first sentence is repetitive with the title/URL. It is functional but not optimally front-loaded.

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?

The tool is simple but the description lacks crucial details: no response structure beyond 'download link and headers', no mention of the 'watermark' parameter's effect, and no output schema. It leaves gaps for an AI agent.

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 50%; the 'url' parameter is documented with examples, but 'watermark' is not described. The description adds no parameter-level information beyond what the schema provides, failing to compensate for the gap.

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 downloads media by URL and provides the download link and headers. It distinguishes from sibling tools like get_v1_media_video_download_by_id by specifying 'by URL', though it could be more explicit about the video resource.

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?

Minimal guidance: only instructs to use the headers and URL from the response, with a link to redoc for an example. No when-to-use or when-not-to-use compared to alternatives.

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