set_curve_property

Set properties like resolution, bevel depth, or fill mode on a curve object in Blender by specifying the curve name, property, and value.

Instructions

Set a property on a curve object.

Args: curve_name: Name of the curve object. property: Property to set - resolution_u, fill_mode, bevel_depth, bevel_resolution, extrude, twist_mode, or use_fill_caps. value: Value to set. Type depends on property.

Returns: Confirmation dict with property name and new value.

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 a return confirmation dict but no side effects, permissions, or error conditions, which is insufficient 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.

Conciseness4/5

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

The description is short and structured with args and returns, but it could be more concise by removing repetitive phrasing like 'Name of the curve object'.

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 no annotations and an output schema exists, the description covers the core purpose and parameters adequately but lacks details on prerequisites, error handling, or relation to other curve tools.

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 0%, but the description lists allowed property values and notes that value type depends on property. However, it does not specify expected types for each property, leaving ambiguity.

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 it sets a property on a curve object, listing specific properties. This distinguishes it from sibling tools like set_camera_property or set_light_property, which operate on different object types.

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 indicates what the tool does but does not provide explicit when-to-use or when-not-to-use guidance, leaving the agent to infer from the tool name and context.

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