unity_redo

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

The description states the basic behavior but provides no additional traits (e.g., safety, side effects, failure cases). Without annotations, it only covers the obvious redo action.

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?

One concise sentence (9 words) that is front-loaded and contains no superfluous information.

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 simple redo tool, the description is mostly adequate. It could mention prerequisites (e.g., need a prior undo) or return value, but is otherwise sufficient given the tool's simplicity.

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 coverage is 100% with a clear description of the port parameter. The tool description adds nothing beyond the schema, so baseline score applies.

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 in Unity Editor' uses a specific verb (Redo) and resource (last undone operation), clearly distinguishing it from siblings like unity_undo and unity_undo_history.

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?

No explicit when-to-use or when-not-to-use guidance. The description implies usage after an undo, but does not mention alternatives or prerequisites like requiring an existing undo history.

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