suno_cover_music

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

No annotations are provided, so the description carries full burden. It describes the high-level function but omits behavioral details such as asynchronous nature (implied by callback_url parameter), idempotency, costs, or side effects. The return value is mentioned minimally.

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 at five sentences, including a structured 'Use this when:' section with three bullets and a 'Returns:' line. Every sentence adds value, and the key information is front-loaded in the first sentence.

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 moderate complexity (6 parameters, 1 required, output schema present), the description covers the main purpose, usage scenarios, and return format. It is mostly complete, though it could mention the asynchronous nature of the task for better completeness.

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?

With 100% schema description coverage, the baseline is 3. The main description adds overall context by mentioning 'core melody and lyrics' and different styles, but does not elaborate on individual parameters beyond what the schema already provides. No additional meaning is added.

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 creates a cover or remix of an existing song in a different style, with a specific verb ('Create') and resource. It distinguishes from sibling tools like suno_remaster_music and suno_generate_music by focusing on altering style while keeping melody/lyrics.

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 'Use this when:' section with three detailed bullet points provides clear context for when to use the tool, such as wanting a different genre or acoustic version. However, it does not explicitly mention when not to use it or suggest alternatives among siblings.

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