producer_cover_music

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

With no annotations, the description carries full burden. It explains that the tool generates a new version with different arrangement/genre/mood while keeping core melody and lyrics. It also mentions return values (Task ID and cover audio info), covering key behavioral aspects.

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 succinct, with a clear header, a brief explanation, a bulleted list of use cases, and a return statement. It is front-loaded and every sentence serves a purpose.

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 has 5 parameters, all well-described, and an output schema exists. The description adequately explains the purpose and usage, though it could mention the model selection or callback_url behavior, but these are covered by schema.

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 baseline is 3. The description adds value by providing examples for 'prompt' and 'style' parameters and clarifying that 'audio_id' is from a previous generation, beyond the schema descriptions.

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 'Create a cover or remix version of an existing song in a different style,' which is a specific verb+resource. It distinguishes from siblings like producer_variation_music and producer_generate_music by focusing on covers/remixes.

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 explicit scenarios for when to use the tool (different genre, acoustic version, remix with different vibe). This gives clear context, but does not explicitly mention when not to use it or name alternative tools.

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