get_v1_media_music_download_by_url

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It states the tool returns a download link and headers but fails to mention authentication requirements, rate limits, or whether any state changes occur. The description does not warn about potential errors, quotas, or prerequisites beyond the URL parameter. This is minimal transparency for a download-oriented tool.

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 concise—two sentences plus a link—and front-loaded with the HTTP method and path. Every part serves a purpose, though the markdown link to an external doc could be considered unnecessary clutter. It efficiently communicates the core function without excess verbiage.

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's complexity (one parameter, no output schema), the description offers a moderate level of completeness. It explains the return value conceptually ('download link and headers') but lacks specifics on response structure, error handling, or usage context. Without annotations or an output schema, more detail would improve completeness for an 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?

The input schema has 100% coverage with a single parameter 'url' including examples and description. The description adds the phrase 'by media url' but does not provide additional semantics beyond what the schema already offers. Since schema coverage is high, a baseline of 3 is appropriate; the description does not substantially enhance parameter 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: 'Download Audio By Url' and 'Get download link and headers by media url.' It explicitly identifies the resource (audio from a media URL) and the action (providing download link and headers). The name and description distinguish it from sibling tools like get_v1_media_video_download_by_url and get_v1_media_music_download_by_id, making the purpose specific and unambiguous.

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 such as get_v1_media_music_download_by_id or get_v1_media_video_download_by_url. There are no 'when-not' conditions or context for selecting this tool over siblings. The only instruction is to 'use the headers and url taken from the response,' which is a post-usage step, not a selection criterion.

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