mcp_opendaw_duplicate_note_region

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

With no annotations provided, the description carries the full burden and handles it well: it states that the operation copies the region and all its notes, implying non-destructive behavior, and explains the return value (new region index). It does not cover error cases or permissions, but for a duplicate action this is reasonably transparent.

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: a one-line summary, followed by behavioral detail, use case, parameter list, and return value. Every sentence is informative, and it is neither too short nor too verbose.

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 four-parameter tool with an output schema, the description covers purpose, behavior, parameters, and return value, meeting the minimum for correct invocation. It could explicitly note differences from similar tools (e.g., duplicate_region) and potential side effects, but the current content is sufficient.

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?

The description offers detailed explanations for all four parameters, including special values (unit_index=-1) and an example for offset_beats. Since the schema coverage is 0%, this fully compensates and provides beyond-schema meaning.

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 the tool's function with a specific verb ('Duplicate'), a resource ('note region'), and a behavior (copies region and notes to offset_beats). It differentiates from sibling tools like duplicate_region by emphasizing note region and new position, and the repeating-pattern example reinforces the purpose.

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 'Useful for repeating patterns' line provides a clear use case and example, giving contextual guidance. However, it does not explicitly exclude alternatives or mention when not to use it, though the note-region specificity implicitly narrows its scope.

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