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

With no annotations provided, the description carries the full burden. It explains that the tool generates a new version while retaining core melody/lyrics and states the return value (Task ID and cover audio info). However, it does not disclose details like async behavior, model impact, or potential side effects, which would be valuable context.

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 and well-structured, with a clear opening statement, bulleted use cases, and a returns section. Every sentence adds value, and the format makes it easy to scan.

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 rich schema (6 params, enums, output schema) and no annotations, the description provides sufficient context: purpose, usage scenarios, and return type. It could mention that audio_id must come from a previous generation, but the schema already states that, so coverage is adequate.

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%, so the baseline is 3. The description does not add much parameter-level meaning beyond reinforcing the purpose; the schema already provides comprehensive descriptions for all 6 parameters, including examples for style and prompt.

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 version of an existing song in a different style, using the specific verb 'create' and resource 'existing song'. It distinguishes from sibling tools by emphasizing the transformation of an existing track while preserving melody and lyrics, which is distinct from pure generation or variation tools.

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 provides three concrete scenarios (different genre, acoustic version, remix with different vibe), giving clear context for when to use this tool. However, it does not explicitly mention alternatives or exclusions, so it falls short of a 5 but is still strong.

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