mcp_opendaw_create_drum_solo

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

No annotations are provided, so the description carries full burden. It explains that the tool generates a complete drum solo with specific structural elements and returns notes and solo characteristics. However, it does not explicitly state whether it modifies existing data or creates new content, and does not mention any potential side effects. This is good but not perfect.

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 clear opening sentence, bullet-pointed genre details, parameter list, and examples. Each section adds value without redundancy. It is appropriately sized for the tool's complexity.

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 (7 parameters, no annotations, output schema exists), the description covers the core functionality, parameter semantics, and return description well. Minor omission: the standard parameters unit_index and track_index are not explained, which could affect completeness for an agent unfamiliar with the system.

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 adds significant value by documenting parameters: solo_type (with genre-specific details), bars (range 2-16, default 4), velocity (0-1, default 0.9, with note on loudness), and seed (PRNG). It also provides examples. However, parameters start_beat, unit_index, and track_index are not described in the text, which is a minor gap.

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's purpose: 'Create a genre-specific drum solo with rudimental vocabulary.' It distinguishes itself from the sibling 'create_drum_fill' by specifying that it creates a full multi-bar solo with phrasing, build-ups, climax, and genre-specific patterns. The purpose is specific and unambiguous.

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 explicitly differentiates this tool from 'create_drum_fill' (short transition) and lists five distinct genres (rock, jazz, funk, latin, marching) with detailed characteristics. It provides clear guidance on when to use this tool versus alternatives.

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