duplicate_asset

Duplicate an Unreal Engine asset from a source path to a destination path, creating a copy at the target location. Simplifies asset management by reusing existing assets without manual copying.

Instructions

Duplicate an asset to a new path.

Behavior2/5

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It does not mention what happens if the destination path already exists, whether references are updated, or any failure modes. The description only states the basic action without side effects or constraints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no redundant words. It is front-loaded with the core action and resource, making it easy to scan. It could be more detailed, but that is a completeness issue, not a conciseness issue.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is extremely sparse for a tool with no output schema and no annotations. It does not clarify key details such as whether destination_path must include a new asset name, how collisions are handled, or whether the operation is recursive. This leaves the agent with unanswered questions for a mutation operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters (source_path and destination_path) are already documented in the schema. The description adds no additional meaning beyond the schema, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the specific verb 'Duplicate' with a clear resource ('an asset') and outcome ('to a new path'). It clearly distinguishes from sibling operations like rename_asset or delete_asset, which have different intents.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as rename_asset, import_asset, or duplicate_actors. There are no exclusions, prerequisites, or example scenarios.

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