Behavior3/5

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

The description states the return value (Task ID and extended audio info) but does not disclose behavioral nuances such as whether the original audio is modified, required permissions, or any side effects. With no annotations, more detail is needed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded with the main action, with bullet points for usage scenarios. Some slight redundancy ('your own music' appears twice) keeps it from a perfect score.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the tool's purpose, differentiation, usage, and return. With a rich schema and output schema, it provides sufficient context for selection, though additional details about model options are left to schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All parameters have descriptions in the schema (100% coverage), so the description does not need to repeat them. The description does not provide additional semantic context beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool extends uploaded audio with AI-generated content and distinguishes it from the similar suno_extend_music by specifying it works only with audio uploaded via suno_upload_audio.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit usage scenarios ('Use this when: ...') and mentions the alternative tool suno_extend_music, giving clear guidance on when to use this tool.

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