mcp_opendaw_delete_note_region

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

The annotation destructiveHint=true already signals destructive behavior. The description adds minimal behavioral context; it mentions 'from the timeline' but does not specify whether the deletion is permanent, whether it affects contained notes, or any side effects. It does not contradict annotations but provides little beyond them.

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 compact: one sentence for the action and three concise parameter lines. No filler or redundant information. It's front-loaded with the primary purpose.

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?

With an output schema present and annotations covering destructive intent, the description provides the essential parameter details. However, it lacks usage guidance and behavioral nuancing such as undoability or effects on dependent regions, leaving some gaps for an agent in a complex DAW context.

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 description coverage is 0% and no parameter descriptions exist in the schema. The description compensates by explaining all three parameters: unit_index with '-1 = search all AUs', track_index as within the AU, and region_index as 0-based. This fully covers the semantics for an agent.

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 states 'Delete a note region from the timeline' with a clear verb and resource. It identifies the target as a note region, distinguishing it from audio regions, but it doesn't explicitly differentiate it from sibling tools like delete_region or delete_audio_region, so it lacks explicit sibling differentiation.

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?

No when-to-use or alternative guidance is provided. The description only defines the operation and parameters, with no context on when to choose this over other delete tools (e.g., delete_region, delete_audio_region) or any prerequisites.

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