mcp_opendaw_insert_rests

Insert rests at specified beat positions by deleting, truncating, or shortening overlapping notes to add silence and rhythmic variation in a DAW track.

Instructions

Insert rests at specified beat positions by removing notes.

Deletes notes at given beat positions to create space, syncopation, or breathing room in dense patterns. Unlike thin_notes (which removes by interval/velocity/random strategy), this works positionally — you specify exactly where rests should appear.

Args: unit_index: Audio unit index track_index: Note track index region_index: Region index (-1 = first region) rest_positions: Comma-separated beat positions where rests should be inserted (e.g. "0,1,2,3" = every beat, "1.5,3.5" = offbeats only). tolerance_beats: Tolerance for matching note start to rest position (0.05 = within a 32nd note, 0.25 = within a 16th). mode: Deletion mode — "delete" = remove notes starting at rest positions, "truncate" = shorten notes that overlap rest positions (cut them at the rest point), "shorten" = reduce duration of notes near rest positions by half but don't delete them. shorten_neighbors: If True, also shorten notes immediately before rest positions to create cleaner separation. Only with mode="delete".

Behavior4/5

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

The description details the tool's behavior: it removes notes at specified beat positions, and explains the three deletion modes (delete, truncate, shorten), tolerance, and neighbor shortening. No annotations are provided, so the description carries the full burden. It clearly communicates the destructive nature but does not mention undo behavior or error handling.

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?

The description is well-structured with a brief intro, comparison to a sibling, and a detailed Args section. While comprehensive, it could be slightly more concise; however, it remains readable and front-loaded with essential information.

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

Completeness4/5

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

Given that an output schema exists, the description does not need to explain return values. It adequately covers the tool's behavior, parameter meanings, and mode details. Missing elements like prerequisites (e.g., existence of notes at positions) are minor gaps.

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?

The input schema has 0% description coverage, but the 'Args' section in the description provides thorough explanations for all 7 parameters, including examples (e.g., '0,1,2,3' for rest_positions) and clarifications (tolerance in musical terms like 'within a 32nd note'). This adds significant value beyond the schema.

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?

The description clearly states the tool's purpose: 'Insert rests at specified beat positions by removing notes.' It explains the effect (creating space, syncopation, breathing room) and distinguishes itself from the sibling tool 'thin_notes' by emphasizing positional control rather than interval/velocity/random strategies.

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

Usage Guidelines4/5

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

The description explicitly contrasts with 'thin_notes,' providing a clear alternative and indicating when to use this tool (positional rest insertion). However, it does not mention other potential alternatives like 'delete_note' or conditions when not to use this tool, slightly limiting guidance.

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