mcp_opendaw_undo

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action without mentioning side effects, whether it's single-level or multi-level undo, what happens if there is nothing to undo, or any irreversible consequences.

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 a single, short sentence that immediately states the action, with no filler or redundant context. It is concise and front-loaded.

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 zero-parameter tool, the description covers the core action, and the presence of an output schema means return values needn't be explained. However, it lacks details about the scope of undoable operations and error behavior, leaving some gaps for a tool in a large 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?

The tool has zero parameters, so the input schema fully covers parameter semantics. The description adds no parameter information, but with no parameters, the baseline is 4, and nothing is missing.

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 uses a specific verb 'undo' and identifies the resource as 'the last editing operation', which clearly conveys the tool's purpose. It is distinct from siblings like mcp_opendaw_redo, though it doesn't elaborate on what counts as an 'editing operation'.

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 implies use when you want to revert the most recent editing action, but provides no explicit guidance on when not to use it, such as in scenarios where the last operation wasn't an 'editing' one, or how it relates to the redo tool as an alternative.

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