app-redo

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It states that it runs redo but does not explain side effects, such as what happens if there is nothing to redo, whether it is reversible, or how it affects the session state. The description is too minimal to be transparent.

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 with no filler or redundancy. It front-loads the key information and is appropriately sized for a parameterless action.

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?

Given the tool's simplicity (no parameters, no output schema), the description is minimal but adequate. However, it lacks context about what 'redo' means in Blender (e.g., redoes the last undone operation) and does not specify any limitations. This is a gap that could confuse an agent unfamiliar with the domain, so it is not fully complete.

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 the input schema is empty. Since there is nothing to describe, the description adds no parameter information but also does not need to. The baseline for zero parameters is 4, and the description does not conflict with this.

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 'Run Blender redo for the active session' clearly identifies the action (redo) and context (Blender, active session), distinguishing it from siblings like app-undo. It is not a tautology and conveys the resource and operation effectively, though the verb 'run' is generic.

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 app-undo. The description does not mention that redo should follow an undo, nor does it specify any conditions or prerequisites. Usage context is only implied by the name 'redo'.

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