armorpaint_redo

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

Annotations already indicate this is not read-only, not idempotent, and not destructive, so the safety profile is covered. The description adds useful scoping by specifying that the redo targets the most recently undone operation, but it does not disclose what happens when there is no undo history or whether repeated calls consume multiple entries from the redo stack. For a no-parameter tool this is a moderate but not severe gap.

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, front-loaded sentence with no wasted words. It states the action and the precise object in under ten words, which is ideal for a simple tool definition.

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 has no parameters and an output schema exists, the description is largely complete for selecting and invoking it. The only missing detail is the behavior when there is nothing to redo (e.g., no prior undo), which would be useful but is not critical for the common case.

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 input schema has zero parameters, so the description carries no parameter-documentation burden. The schema already covers everything, and a baseline of 4 is appropriate for a parameterless tool.

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 uses a specific verb ('Redo') and a specific target ('the most recently undone operation'), making the tool's function unambiguous. It also differentiates itself from the sibling armorpaint_undo by explicitly referring to an undone operation rather than an operation to be undone.

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 the tool should be used after an undo has occurred, meaning there is an undone operation to redo. However, it does not explicitly state when not to use it, mention that it requires a prior undo, or reference alternative tools such as armorpaint_undo.

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