clone_node

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. 'Clone an existing node' implies a mutating operation, but it does not clarify whether the original node is preserved, where the clone is inserted, how x and y affect positioning, or what side effects occur. This is a significant gap for a mutation tool.

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 wasted words, and the key action is front-loaded. However, it is so brief that it sacrifices behavioral and contextual detail, making it concise but underinformative.

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?

The tool has no annotations, no output schema, and a description that only states the basic action. It does not explain the resulting node's placement, relationship to the original, return value, or whether x and y are optional/required together. This is incomplete for an agent expected to invoke the tool correctly in a broader design workflow.

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 100% description coverage, so the schema already explains nodeId, x, and y. The description adds no extra parameter semantics beyond confirming the nodeId refers to an existing node. Baseline 3 is appropriate because the schema handles the burden.

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 states a specific verb ('Clone') and a clear resource ('an existing node in Figma'), which makes the core purpose understandable. It does not explicitly differentiate from siblings like create_rectangle or move_node, but the verb 'clone' semantically implies duplication of an existing node, distinguishing it from creation or transformation tools.

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 guidance on when to use this tool versus alternatives, nor does it mention when not to use it. An agent must infer from the name and description that this is for duplicating an existing node, and there is no comparison with sibling operations such as create_frame or create_component_instance.

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