mcp_opendaw_delete_automation_event

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

Annotations already indicate destructiveHint=true. The description confirms destructive behavior ('delete') and adds context about the value region and indices. However, it does not disclose side effects, prerequisites, or undo support, so it adds moderate value beyond annotations.

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 very concise: four sentences total, with the purpose front-loaded and parameter explanations following. No superfluous text.

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?

The description covers the action, parameters, and return type (success or error). It does not discuss prerequisites, error conditions, or behavior with invalid indices, but given the output schema exists and the tool is part of a larger set, it is reasonably complete for a delete operation.

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%, so the description must compensate. It provides meaningful explanations for all three parameters (unit_index, track_index, event_index), describing their roles and context (e.g., 'Track index within the unit (automation track)'). This adds value beyond the schema property titles.

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 it deletes a single automation event (ValueEventBox). It specifies the exact resource type and action, and the sibling tools include create, update, duplicate, list, and move automation events, so the purpose is well-distinguished.

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 description does not provide explicit guidance on when to use this tool versus alternatives like delete_audio_region or delete_note. Usage is implied by the tool name and context (automation events), but no when-not or comparative guidance is given.

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