mcp_opendaw_quantize_notes

Align note positions to a grid (1/4 to 1/64) with adjustable snap strength. Returns count of quantized notes.

Instructions

Quantize note positions to a grid division.

Snaps each note's start position to the nearest grid line.

division: Grid division — '1/4', '1/8', '1/16', '1/32', or '1/64'. unit_index: Audio unit index (-1 = all AUs). track_index: Specific note track (-1 = all note tracks). strength: 1.0 = full quantize, 0.5 = 50% (keeps some groove).

Returns count of notes quantized.

Behavior3/5

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

No annotations provided, so description carries full burden. It explains the effect on note positions and the strength parameter, but does not disclose mutation behavior, undoability, or side effects. Adequate but not thorough.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is concise with a clear first sentence and bullet-like parameter explanations. Could be more structured with sections, but no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers main behavior and return value, but lacks context on error conditions, idempotency, range of index parameters, and whether the operation is reversible. Given no annotations, slightly incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, description adds full meaning for all 4 parameters: division values, unit_index default, track_index default, and strength interpretation. Essential for correct invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'quantize' and the resource 'note positions', and explains it snaps to a grid. It distinguishes itself from sibling tools like 'quantize_velocities' by focusing on positions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool vs alternatives (e.g., 'apply_swing', 'humanize_notes'). Does not mention prerequisites or when not to use it.

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