redo

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

With no annotations, the description carries the full burden of disclosing behavior. 'Redo' implies restoring a previously undone action, but the description does not state whether it redoes a single action or multiple, whether it depends on a prior undo, or what side effects occur. The phrase 'expanded operation' adds confusion rather than clarity. No behavioral detail is disclosed.

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 short but this is under-specification rather than conciseness. 'Expanded operation' is filler that does not explain anything. The useful word 'redo' merely echoes the tool name. A helpful description could still be one sentence, e.g., 'Redoes the most recently undone edit in the active sequence.'

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 sibling context includes 'undo' and 'multiple_undo', the description should clarify how redo relates to them, whether it restores one step or multiple, and whether it operates on the active sequence. No output schema or annotations exist to compensate. The current description leaves these aspects entirely to the agent's prior knowledge of the term 'redo'.

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 schema is an empty object, so there are no parameter semantics for the description to clarify. The schema fully covers this surface, making the baseline 4 appropriate. The description adds nothing about parameters, but none are needed.

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 is essentially 'redo' restated with a domain prefix ('Premiere Pro') and the descriptor 'expanded operation', which is never explained. It does not state a specific verb plus resource, nor does it differentiate redo from the sibling 'undo' or 'multiple_undo' tools. This is close to a tautology.

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 redo versus undo, multiple_undo, or any other sibling. The description does not mention conditions, prerequisites, or alternatives. No usage context is provided beyond the name itself.

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