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

With no annotations, the description carries the burden of behavioral disclosure. It details how each track behaves across sections, the chord progression, and section lengths. However, it does not mention whether existing notes on target tracks are overwritten or if there are any destructive side effects.

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 well-structured with sections, bullets, and an example, but it is verbose. The musical theory explanations (chord progression comparisons) are informative but could be trimmed without losing essential guidance. Every sentence earns its place, but some could be more concise.

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?

For a complex 4-track arrangement tool with 11 parameters, the description covers track behaviors, section structure, parameter ranges, and an example. Given that an output schema exists, return values are not over-explained. Missing operational details like prerequisites for unit_index and handling of existing notes keep it from a 5.

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 descriptions are absent (0% coverage), so the description compensates by explaining most parameters: bpm range, bars range, root note, octave MIDI value, and track indices. It misses velocity and start_beat, and does not deeply explain unit_index, but overall adds substantial meaning beyond the schema.

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 full pop arrangement with verse-chorus-bridge structure across 4 tracks. It is specific about the output and distinguishes itself from loop-based arrangements and other genre arrangements.

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 description explains when this tool is appropriate (pop music with real song form) and differentiates it from loop-based arrangements, rock (I-IV-V), and jazz (ii-V-I). It does not explicitly name alternative tools, but the context is clear and actionable.

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