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

With no annotations, the description carries the full burden of behavioral disclosure. It carefully details the four tracks, their musical content, defaults, and return value ('Returns notes created per track and total'). However, it does not explicitly state whether existing tracks are overwritten, how start_beat interacts with the arrangement start, or what side effects unit_index has, leaving some behavioral ambiguity.

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 clear sections: overview, genre characteristics, track breakdown, parameter list, and examples. The genre bullet points are somewhat lengthy but provide valuable stylistic context for generating authentic neurofunk; every sentence serves a purpose and the front-loaded summary is effective.

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 description thoroughly covers creative output, genre conventions, parameter defaults, ranges, and example invocations. However, critical gaps remain: velocity, start_beat, and unit_index are unexplained, and the tool's behavior regarding track creation (new vs. existing) is not clarified. Given the tool's complexity (11 params, 4 tracks), the description is helpful but not fully complete.

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 description explicitly explains bpm, bars, root, and octave with defaults and ranges, and infers the track-index parameters via the numbered track list (drum_track, bass_track, reese_track, stabs_track). However, velocity, start_beat, and unit_index receive no explanation, leaving 3 of 11 parameters undocumented—a significant gap given the schema itself has zero 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 opens with a specific verb+resource+scope: 'Create a full neurofunk DnB arrangement — 4 tracks: drums + sub-bass + Reese + stabs.' It clearly delineates the tool's function and distinguishes it from sibling genre-arrangement tools by naming the neurofunk style and the exact track structure.

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 provides clear context for when to use the tool: when a neurofunk DnB arrangement is desired, with BPM, key, and bar ranges. It does not explicitly name alternative tools (e.g., create_liquid_dnb_arrangement) or state when not to use it, but the genre-specific detail effectively implies the usage scenario.

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