mcp_opendaw_delete_signature_change

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

The description provides details beyond the destructiveHint annotation: it clarifies that deletion uses closest match by position and explains the -1 special values for index and position_beats.

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 reasonably concise but contains some redundancy (e.g., the initial line and then parameter explanations). Could be tightened.

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?

It covers the two parameter usage, mentions the return value (updated signature event list), and handles the edge case of deleting the last event. Missing error cases, but sufficiently complete for a simple delete tool.

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?

Since the input schema has no parameter descriptions, the tool description adds crucial semantics: it defines position_beats as the position to match and index as 0-based index, including the special -1 case.

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 time signature change from the timeline' with a specific verb and resource, and it distinctively separates from siblings like add_signature_change or move_signature_event.

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?

It explains two deletion modes (by position or by index) and notes the special case for deleting the last event, but lacks explicit guidance on when to choose one mode over the other or comparison with alternative tools.

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