redo

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it offers none. It does not state whether the tool modifies the timeline, whether it is a safe read-only operation, or what the outcome of invoking 'redo' would be. The description is completely uninformative.

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 extremely short, but this is under-specification rather than efficient conciseness. A single sentence that merely restates the tool name does not earn its place; it omits essential information. It is not appropriately sized because it fails to convey any usable 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?

Given the tool's simplicity and the absence of annotations, output schema, and parameters, the description still fails to be complete. It does not clarify the tool's purpose, its relationship to undo, or any behavioral details. The description is as minimal as possible but entirely inadequate for an agent to understand or invoke the tool.

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 0 parameters, and the schema is permissive with additionalProperties allowed. Since there are no defined parameters, the description's lack of parameter details is not a significant gap. The baseline for 0 parameters is 4, and neither the description nor schema introduces ambiguity that would lower it.

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 'Premiere Pro expanded operation: redo' is a tautology—it merely restates the tool name 'redo' without explaining what the operation does. There is no specification of the action, resource, or effect beyond the name itself, making it impossible to distinguish from a generic concept.

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 provides no context for when to use this tool. It does not mention 'undo' or 'multiple_undo' as alternatives, nor does it explain that 'redo' typically reverses a previous undo. There is no guidance on appropriate usage scenarios.

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