mcp_opendaw_create_walking_bass

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

With no annotations, the description fully explains the walking bass algorithm (beat roles: root, chord tone, passing tone, approach note) and what the tool returns (notes created, summary). It does not mention side effects or auth requirements, but the algorithm and output are well-covered.

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 action, musical context, parameter list, algorithm explanation, and example. It is slightly long but each section adds value. Could be tightened by removing redundancy in the parameter descriptions already in schema titles.

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 of walking bass generation and the presence of an output schema (inferred), the description covers input, algorithm, and output. It does not address edge cases (e.g., empty chords) but is otherwise sufficient for the tool's purpose.

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?

Since schema description coverage is 0%, the description compensates by explaining most parameters: chords format, octave range, velocity range, bars_per_chord meaning, and mentions unit_index and track_index. However, unit_index and track_index are not fully explained beyond 'AU index' and 'Note track index', which is somewhat clear but could be more explicit.

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 creates a walking bass line over a chord progression, specifying the resource (bass line) and action (create). It distinguishes from siblings like create_bassline and create_electronic_bass by the specific walking bass style and algorithm, and ties it to jazz, blues, and swing contexts.

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 implies usage for jazz/blues/swing and walking bass patterns, but does not explicitly state when to use this tool versus alternatives like create_bassline or create_bass_from_progression. No when-not or alternative guidance is provided.

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