mcp_opendaw_delete_note_region

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

The annotation destructiveHint=true already indicates destructive behavior. The description adds no further behavioral context (e.g., permanence, undo capability, side effects) beyond stating the deletion action.

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?

Extremely concise: one line for the action and one line per parameter. No unnecessary words or redundancy.

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 simple delete operation, the description covers the core functionality and parameter semantics. However, it omits any mention of return value or error handling, though an output schema exists (not shown).

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 provides critical parameter details missing from the schema: unit_index can be -1 to search all AUs, track_index is within the AU, region_index is 0-based. Since schema description coverage is 0%, this adds essential 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 'Delete a note region from the timeline', specifying the exact resource and action. It distinguishes from sibling tools like delete_audio_region and delete_note by using 'note region', but does not elaborate on what constitutes a note region.

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 guidance on when to use this tool versus alternatives such as delete_region, delete_note, or delete_audio_region. The agent must infer usage from the tool name alone, which is insufficient.

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