blender_configure_world

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

With all annotations set to false, the description carries the full burden of behavioral disclosure. It states that this is a mutation ('Set') but does not explain side effects, whether the operation is idempotent, how it interacts with existing world settings, or what happens after the change. No behavioral context beyond the bare action is provided.

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?

A single sentence that is direct, front-loaded, and free of filler. It states the action, target, and value format efficiently, making it easy for an agent to parse quickly.

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?

For a two-parameter tool with no output schema and no annotation hints, the description is adequate for basic invocation but not fully complete. It omits usage guidance, behavioral side effects, and meaningful semantics for the strength parameter. The tool is simple enough that these omissions are not catastrophic, but a more robust description would improve completeness.

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 schema already documents the color parameter as 'Linear RGB color [r, g, b]', so the description's repetition of 'linear RGB' adds little for color. For strength, the description attaches it to the background but does not clarify its meaning, units, or allowed interpretation beyond the schema's minimum of 0. With 50% schema coverage, the description partially compensates but leaves strength underdefined.

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 names a specific verb ('Set'), a specific resource ('Blender World background color and strength'), and the value format ('linear RGB values'). This clearly distinguishes the tool from siblings like blender_set_light and blender_configure_scene, which target different scene elements.

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 implies the tool should be used when the agent needs to change the Blender world background color or strength. However, it does not explicitly state when to prefer this tool over alternatives, nor does it mention any exclusions or prerequisites. The usage context is inferable but not explicitly guided.

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