suno_mashup_lyrics

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

No annotations are provided, so the description carries the full burden. It only says 'intelligently combines' without specifying the combination algorithm, constraints, or potential side effects. Behavioral details like output structure or failure modes are absent.

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 multi-paragraph but remains concise, with a clear structure including a 'Use this when' bullet list. Every sentence contributes meaning, though some redundancy exists (e.g., 'mashup' repetition).

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 with only two string inputs, and the output schema exists, so return values are covered. However, the description lacks details on constraints like maximum length, character encoding, or how incompatible lyrics are handled, leaving gaps 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?

Schema coverage is 100%, and the description adds 'Can be full song lyrics with section markers,' which provides extra context beyond the basic property descriptions. This meets the baseline of 3 for high coverage.

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 verb 'Generate' and the resource 'mashup lyrics', specifying it takes two sets of lyrics and combines them. This distinguishes it from siblings like suno_mashup_music (music) and suno_generate_lyrics (from scratch).

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 a 'Use this when' section listing three specific scenarios, giving clear context for appropriate use. However, it does not explicitly state when not to use it or mention alternatives, such as using suno_generate_lyrics for entirely new lyrics.

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