mcp_opendaw_create_comping

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 explains rhythmic behavior, ghost notes, syncopation, and the return values (notes, chords, rhythm pattern). It does not mention potential side effects on existing notes, but for a creation tool this is a minor omission. The behavior is well-articulated.

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 efficiently structured: clear intro, differentiation, then a parameter list with examples. It is front-loaded with the purpose, and every sentence provides useful information (defaults, examples, semantics) without fluff.

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?

For a 9-parameter tool with one required param and an output schema, the description covers all parameters, return values, usage context, and examples. It also clarifies sibling relationships, making it fully complete for selection and invocation.

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 coverage is 0%, yet the description documents every parameter with detailed semantics: chords format and example, rhythm pattern characters and examples, note_spacing, syncopation, and defaults. This fully compensates for the bare schema and adds substantial value.

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 'Create comping — rhythmic chordal accompaniment' and differentiates from sibling tools by explicitly contrasting with create_chord_progression (sustained blocks) and create_stab (house stabs). The verb and resource are specific, and the unique rhythmic identity is highlighted.

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 explicit guidance on when to use this tool versus alternatives: 'Unlike create_chord_progression (sustained blocks) or create_stab (house stabs), comping gives each chord a rhythmic identity.' It also lists genre examples (jazz, funk, reggae, country) to illustrate appropriate use cases.

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