execute_blender_code

Run Python code in Blender to automate 3D modeling, scene creation, and manipulation by executing arbitrary scripts step by step.

Instructions

Execute arbitrary Python code in Blender. Make sure to do it step-by-step by breaking it into smaller chunks.

Parameters:

  • code: The Python code to execute

Behavior2/5

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

No annotations exist, so the description bears full burden. It fails to disclose side effects on Blender state, error behavior, or return values. For a powerful tool executing arbitrary code, this transparency is insufficient.

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?

Two sentences, front-loaded with the main action. It is concise but could be more structured. The step-by-step advice is useful but brief.

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?

Given the tool's 1 parameter, no output schema, and no annotations, the description lacks details on success/failure, output format, and Blender environment changes. It is incomplete for safe and correct invocation.

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

Parameters2/5

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

The description for parameter 'code' simply restates 'The Python code to execute', which adds no meaning beyond the schema. With 0% schema description coverage, the description should compensate but does not.

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 name 'execute_blender_code' and description 'Execute arbitrary Python code in Blender' clearly state the verb and resource. The tool is distinct from siblings like get_scene_info or generate_hyper3d_model_via_text, which perform different tasks.

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 advises to break code into smaller chunks, providing a usage hint. However, it lacks explicit guidance on when to use this tool versus alternatives or when not to use it. The sibling list implies usage for code execution, but not explicit context.

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