blender_setup_scene

Idempotent

Configure render engine, output resolution, world background, and timeline settings for a Blender scene.

Instructions

Configure scene-level settings — render engine and quality, output resolution, world environment basics, and timeline/FPS.

Use this when: you need to configure render, output, or timeline settings.

Do NOT use for: detailed world shader editing (use blender_edit_nodes with tree_type=SHADER, context=WORLD).

Behavior4/5

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

Annotations (idempotentHint=true, readOnlyHint=false) are not contradicted. Description adds context about setting categories, but does not discuss potential side effects or prerequisites beyond annotations.

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?

Two core sentences plus two bullet-like usage directives. No redundancy or unnecessary details; every sentence adds value.

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

Completeness4/5

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

Given 15 parameters and no output schema, the description covers the tool's scope and usage boundaries adequately. Could mention that all parameters are optional (inferable from required:0), but is sufficient for correct invocation.

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

Parameters4/5

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

Schema coverage is 100% so baseline is 3. Description groups parameters into logical categories (render, output, world, timeline), adding semantic value beyond the individual parameter descriptions.

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 specifies the tool configures scene-level settings for render engine, output, timeline, and world basics, with clear verb 'configure' and resource 'scene-level settings'. It distinguishes from a sibling tool by excluding detailed world shader editing.

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

Usage Guidelines5/5

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

Explicitly states when to use ('configure render, output, or timeline settings') and when not to use ('detailed world shader editing') with a direct alternative tool reference.

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