mcp_opendaw_create_trap_rolls

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 it creates MIDI notes for kick, snare, and hi-hat with specific patterns, and mentions return value. However, it does not disclose potential side effects like overwriting existing notes, error handling, or behavior with invalid track_index.

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-organized with a clear introduction, detailed roll_type breakdown, and parameter list. It is somewhat verbose but informative. Minor redundancy could be trimmed, but overall it is structured and front-loaded.

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 (9 parameters, no required) and lack of annotations, the description is fairly complete. It explains musical context, roll types, parameter defaults, and return values. It lacks coverage of a few parameters and edge cases, but is still substantial.

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%, so description must compensate. It elaborates on roll_type with five subtypes and their musical contexts, and covers bars, kick_pitch, snare_pitch, hat_pitch, velocity with defaults. However, it does not explain start_beat, unit_index, or track_index.

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 trap hi-hat roll patterns, a specific resource, with a verb 'create'. It distinguishes from siblings by focusing on a genre-specific pattern, and includes detailed musical context and examples.

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 extensive guidance on when to use each roll_type with musical examples and references. However, it does not explicitly state when not to use it or directly compare to alternatives like create_boom_bap, though the context is sufficient given sibling names.

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