setup_environment

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

The description reveals that reconfiguring an existing node is not undoable, which is a useful safety warning. However, it does not disclose other behavioral aspects such as return values, handling of omitted parameters, or scene tree side effects beyond the node itself. With no annotations, more transparency would be expected.

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?

The description is a single concise sentence that front-loads the primary purpose and ends with a practical warning. Every part adds value, with no redundant or filler content.

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?

Given the tool's complexity (28 parameters, no output schema, no annotations), the description is too sparse. It fails to explain parameter semantics, expected behaviors when fields are omitted, or return values. The agent would need to infer too much from property names alone.

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?

Schema description coverage is 0%, so the description must compensate for parameter meanings. It only lists high-level categories (sky, ambient, tonemap, etc.) rather than explaining individual parameters like fog_density or tonemap_mode. With 28 parameters, this is insufficient to guide correct usage.

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 clearly states the tool creates or reconfigures a WorldEnvironment, listing the major setting categories. This distinguishes it from sibling tools like setup_lighting or setup_camera_3d, which target different node types.

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 is for environment setup, but does not explicitly exclude alternatives or mention when not to use it. It provides clear context by naming the node type and setting groups, though no explicit comparisons to sibling tools are provided.

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