redo

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

Annotations already mark readOnlyHint=false and destructiveHint=false, so the fact that this is a mutating operation is conveyed structurally. The description adds the 'guarded' and 'Plan or apply' traits, which is context beyond the annotations, but does not disclose specifics like what gets changed, whether it modifies undo history, or what side effects applying may have.

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 entire description is one short, front-loaded sentence: 'Plan or apply one guarded Ableton redo operation.' It conveys the essential mode and guarded nature with zero filler, and every word carries meaning.

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 guarded operation with four parameters and no output schema, the description is underspecified. It does not explain the plan-then-apply workflow, the role of the confirmation token, or what a redo operation actually entails in the Ableton context. The schema helps, but the description alone does not complete the picture.

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 100%, so the four parameters are fully documented in the schema. The description adds no parameter-level semantics beyond what the schema already states, making the baseline 3 appropriate.

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 identifies the tool as performing 'redo' with an explicit 'Plan or apply' dual mode, and names the resource as an 'Ableton redo operation.' It does not explicitly contrast with the sibling 'undo' tool, but the name and verb make the core purpose evident.

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 versus alternatives like 'undo' or 'get_history_state.' The 'Plan or apply' wording implies a guarded workflow, but the description does not state conditions, exclusions, or why this tool is preferred over siblings.

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