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

No annotations are provided, so the description must disclose behavioral traits. It states that it creates a full arrangement across 4 tracks but does not clarify whether existing content on those tracks is overwritten, whether an empty project is required, or whether there are side effects. Parameters like unit_index and start_beat hint at placement but aren't explained, leaving critical operational information 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 well-structured with clear sections: purpose, style explanation, track breakdown, parameter list, and examples. It is a bit long but each section contributes useful context. The bullet-list format aids scanning, and the examples demonstrate typical usage. No redundant or filler content is present.

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 (11 parameters, no schema descriptions, no annotations), the description is incomplete. It covers the musical intent and core parameters but omits functional parameters (track routing, start_beat, unit_index) and behavioral details. While an output schema exists so return values aren't needed, operational prerequisites and parameter semantics remain under-explained.

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 explains bpm, bars, root, octave, and velocity with ranges and defaults, which adds value over the bare schema. However, six parameters (pad_track, bass_track, drum_track, start_beat, unit_index, melody_track) are not explained at all, and schema_description_coverage is 0%. The track descriptions imply a mapping to these but do not explicitly connect them, leaving a significant gap for the agent.

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: 'Create a full liquid drum & bass arrangement across 4 tracks.' It clearly distinguishes from sibling genre arrangement tools by specifying the liquid DnB subgenre and detailing each track's role (smooth breakbeat, melodic sub-bass, lush extended chords, jazz-influenced lead). References to artists (LTJ Bukem, Calibre) further anchor the style.

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 by contrasting liquid DnB with standard DnB ('Instead of Reese bass and Amen breakbeat fury...') and lists track-specific attributes. This strongly implies when to use this tool versus other genre arrangement tools. However, it does not explicitly name alternative tools or state when not to use it, so the guidance remains implicit rather than direct.

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