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

No annotations are provided, so the description carries the burden. It explains the musical output per track and defaults but does not disclose side effects such as whether it overwrites existing tracks, idempotency, or what happens if tracks are already occupied. Missing safety-related behavioral traits.

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 a summary, detailed musical breakdown, parameter list, and examples. It is slightly verbose but effectively organized.

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 complexity (10 params, no annotations, many siblings), the description covers the musical intent and basic usage. However, it lacks guidance on edge cases (e.g., missing tracks, invalid unit_index) and does not fully detail the output format or how it integrates with existing project state.

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 coverage is 0%, so the description must compensate. It describes most parameters (bpm, bars, root, octave, unit_index, track indices) with brief context, but velocity and start_beat are missing from the description. The output schema is referenced but not detailed.

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 it creates a full house music arrangement with specific tracks (drums, bass, stabs). It distinguishes from sibling arrangement tools by being genre-specific and describing the musical pattern in detail.

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 includes examples showing typical usage but does not explicitly advise when to use this tool over alternative genre-specific arrangements. It lacks explicit when-to-use or when-not-to-use guidance.

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