unity_redo

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

No annotations are provided, so the description carries the full burden. It correctly indicates a redo operation (non-destructive, reversible), but does not disclose whether it fails if no undo history exists, or any other behavioral traits.

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?

Single sentence, front-loaded with the core action. No unnecessary words. Perfectly concise for a simple operation.

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 with no output schema and minimal parameters, the description is adequate. It could mention dependency on prior undo history, but this is implicit from the tool's nature.

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% (one parameter well-described). The description adds no new semantics beyond the schema, but the schema is already clear. Baseline 3 + 1 for optional parameter with clear guidance on when to use.

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 the verb 'Redo' and the specific resource 'the last undone operation in Unity Editor', which exactly mirrors the sibling tool unity_undo. This directly distinguishes it from the sibling unity_undo and other tools.

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 usage after an undo operation, but does not explicitly state when not to use or mention alternatives. The sibling unity_undo is the natural counterpart, but no direct comparison is made.

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