get_v1_media_music_download_by_id

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

With no annotations, the description partially discloses behavior: it indicates the response contains headers and a URL to use for the actual download, implying a two-step process. However, it does not clarify that this endpoint returns metadata, not the file itself, and lacks details on side effects or prerequisites.

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 (three sentences) and includes a link to external docs, but the contradictory phrasing undermines its effectiveness. It could be more precise without adding length.

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?

With no output schema, the description should explain the response format. It mentions using headers and URL from the response but does not describe what fields or structure to expect. Relies on external documentation for full understanding, which is insufficient.

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 schema already fully documents the 'id' parameter with pattern and example. The description adds confusion by referencing 'by media url', which could mislead about the parameter's nature. It does not enhance understanding 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 states 'Download Music By Id' and mentions getting download link and headers, but incorrectly says 'by media url' in the second sentence, which contradicts the actual parameter type. This confusion reduces clarity, though the core purpose is discernible.

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 tool over siblings (e.g., get_v1_media_music_download_by_url for URL-based downloads) or context for choosing between them. The description lacks any comparative or situational advice.

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