mcp_opendaw_redo

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

No annotations are provided, leaving the description to carry the full burden of behavioral disclosure. The phrase 'Redo the last undone operation' states the action but does not disclose that this is a mutating operation, whether it can fail if no undone operation exists, or how it affects the redo stack. This is significant for a state-changing tool with no annotation coverage.

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, concise sentence that directly states the action. It is front-loaded and contains no filler or redundant information, earning the highest score for conciseness and structure.

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 parameter-less tool with an output schema, the description is minimally adequate, but it lacks contextual details such as when redo is available (e.g., after an undo), what happens if the redo stack is empty, and any error behavior. Since the tool is simple, a score of 3 reflects that it is usable but has clear gaps in behavioral 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 and an empty input schema, so there are no parameter semantics to describe. The baseline score of 4 is appropriate since no parameter information is needed, and the description does not need to compensate for any schema gaps.

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 'Redo the last undone operation.' uses a specific verb ('redo') and a clear resource ('last undone operation'), which precisely defines the tool's functionality. It also distinguishes this tool from its sibling mcp_opendaw_undo by explicitly stating it reverses an undo, making the purpose unambiguous.

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?

There is no guidance on when to use this tool relative to undo or any other sibling. The description does not mention that redo is only applicable after an undo operation, nor does it provide any exclusions or alternative tool suggestions. Usage context is only implied by the tool's name and standard behavior.

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