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

With no annotations provided, the description carries the full burden of behavioral disclosure. It details AI Studio dispatch to Modal workers, variable credit costs, exclusion of Day Pass/welcome credits, file deletion after processing, auditability via mioffice.ai/account/tasks, workspace unlock structure, and a link to current pricing. This is exceptional transparency for a paid AI tool.

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 front-loaded with the core purpose and organized logically. It contains some tangential clarification about workspace credit packs, making it slightly longer than strictly necessary, but each sentence still provides meaningful context for cost and data handling.

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 lack of annotations and output schema, this description supplies all necessary context: intended result, execution model, cost structure, data retention, accountability, and pricing reference. It leaves little ambiguity about what invoking this tool entails.

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?

The input schema has zero parameters and schema description coverage is 100%, so the baseline is 4. The description adds no parameter semantics, but none are needed because there are no parameters to document.

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 opens with a specific verb-resource statement: 'Remove vocals from any song to create instrumentals or karaoke tracks.' This clearly identifies the tool's purpose and distinguishes it from sibling AI audio tools like mio_ai_audio_enhancer or mio_ai_music_generator.

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 case is explicitly stated ('remove vocals from any song'), providing clear context for when to use this tool. It does not explicitly name alternatives or state when not to use it, but the specificity of the purpose makes the intended usage obvious.

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