suno_mashup_lyrics

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

No annotations are provided, so the description must fully convey behavioral traits. It uses vague language ('intelligently combines', 'cohesive mashup') without disclosing specifics such as handling of section markers, ordering, or potential failures. The return line mentions 'Combined mashup lyrics' but lacks details on format or structure.

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 about 8 sentences long with a clear structure: function statement, use cases listed with bullet points, and a return line. However, it contains repetitive wording ('combines' appears three times) and could be more succinct without losing clarity.

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 simplicity (2 string parameters, no annotations) and the existence of an output schema, the description covers the key points: inputs, use cases, and output purpose. It does not need to detail return format as the output schema provides that. Slight improvement possible by explaining mashup strategy.

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 100%, with each parameter described as 'first/second set of lyrics... can be full song lyrics with section markers.' The tool description adds minimal value beyond restating that it takes two lyrics and combines them. Baseline 3 is appropriate as the schema does the heavy lifting.

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 'Generate mashup lyrics by combining two sets of lyrics' with a specific verb and resource. It distinguishes from siblings like suno_mashup_music (music mashup) and suno_generate_lyrics (single lyric generation) by focusing on blending two sets of 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 description includes a 'Use this when:' list with three explicit scenarios: blending two songs, creating mashup/medley, and seeking creative lyrical combinations. While it lacks explicit when-not-to-use instructions or alternative tool names, the context is clear and actionable.

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