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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the two-step process but does not describe side effects, return value format, required permissions, or any limits. The word 'convenience' implies it's a combined operation, but deeper behavioral details are missing.

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 a single sentence that efficiently conveys the core purpose. It is front-loaded with 'convenience one-shot' and clearly states actions. However, it could benefit from a brief additional sentence on key parameters or usage context.

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 complexity (7 parameters, composite operation, many siblings), the description is too brief. It does not clarify output, parameter roles, or when to use this composite versus separate steps. The existence of an output schema is not leveraged in the description.

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 0%, so the description must add meaning. It only implies file_path and tempo_bpm from the description. The other five parameters (seed, density, register, similarity, call_response) are not explained or even hinted at, leaving their semantics unknown.

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 that this tool extracts a vocal guide from a WAV file and generates a complementary MIDI melody in beat-space. It explicitly distinguishes itself from sibling tools that perform these steps separately (midi_extract_vocal_guide, midi_generate_complement).

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 phrase 'convenience one-shot' hints at using this tool when both steps are desired together, but it does not provide explicit criteria for choosing this over calling individual steps. No prerequisites or exclusions are mentioned.

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