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

No annotations are provided, so the description carries the full burden. It transparently describes the musical behavior of each track, including patterns, scales, and stylistic distinctions. It also mentions return value ('Returns notes created per track and total'). However, it does not disclose whether existing notes on target tracks are overwritten or if specific track prerequisites must exist.

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 long but well-structured with a summary, per-track bullets, tempo guidance, parameter explanations, and examples. Every sentence adds value—musical rationale, constraints, or usage. It is appropriately sized for a complex 11-parameter tool and is front-loaded with the core purpose.

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 complexity and lack of annotations, the description covers musical patterns, parameter constraints, examples, and return behavior. The output schema exists, so return values need not be detailed. The main gap is not stating whether the tool assumes existing tracks or creates them, and not clarifying behavior with pre-existing notes.

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%, but the description compensates by explaining 9 of 11 parameters, including defaults and constraints (e.g., bars must be multiple of 8, octave meaning with a concrete example). It omits velocity and start_beat, which are two undocumented parameters in the schema. Overall, it adds significant value 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 it creates a full country arrangement with specific track roles (drums, bass, chords, lead). It distinguishes this from other genre tools by detailing the musical pattern (boom-chick, root-five bass, major pentatonic lead) and contrasting with blues ('not shuffled like blues'). It goes far beyond a generic 'create arrangement' statement.

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 (classic country/Americana) and gives tempo guidance for different sub-styles (two-step, ballad, bluegrass). However, it does not explicitly name alternative tools or state when not to use it, though the sibling list and genre-specific detail imply the appropriate scenario.

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