material_duplicate

Duplicate a material in Blender by specifying the source name and optional new name. Creates an exact copy for reuse.

Instructions

Duplicate an existing material.

Args: material_name: Source material name new_name: Name for the copy (auto if empty)

Behavior2/5

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

No annotations are provided, so the description carries full burden. It mentions 'Duplicate' and the new_name parameter behavior, but fails to disclose important traits like what happens if material_name doesn't exist, conflict handling, or side effects like memory usage.

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 extremely concise: one sentence for purpose and an Args list. It is front-loaded and contains no superfluous text.

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

Completeness3/5

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

Given the simplicity of the tool and lack of output schema, the description covers the basics. However, it omits error cases, auto-naming details, and return value, which could be helpful for an AI agent.

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?

The description adds meaning beyond schema titles with 'Source material name' and 'Name for the copy (auto if empty)'. Since schema description coverage is 0%, this compensation is adequate but not exceptional.

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 clearly states 'Duplicate an existing material.' This is a specific verb+resource combo that immediately distinguishes it from sibling tools like material_assign or material_create_pbr.

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

Usage Guidelines3/5

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

The description implies when to use (when you need a copy of a material) but provides no explicit guidance on when not to use or alternatives. For a straightforward duplicate operation, this is adequate but lacks depth.

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