create_world_environment

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

With no annotations, the description carries the full burden of disclosing behavioral traits. It states the output is a .tscn file and that it references an Environment, but it does not mention whether existing files are overwritten, whether parent directories are created, what happens if the environment_path is invalid, or what the return value is. The behavior is largely opaque beyond the basic creation action.

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, front-loaded sentence that directly states the tool's purpose. It contains no filler or redundant information, and every word contributes to the meaning. This is an ideal length for a simple creation tool.

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 absence of web_search global annotations and output schema, the description needs to provide more context about side effects and prerequisites. It does not mention overwrite behavior, directory creation, error handling, or return values, leaving significant gaps for an agent to safely invoke the tool. The schema covers parameter semantics but not the overall execution behavior.

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 100% and both parameters have detailed descriptions, including the optional behavior of environment_path (inline default if omitted). The tool description adds no additional parameter semantics beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 a .tscn file containing a WorldEnvironment node that references an Environment. It is specific about the output resource and node type, which distinguishes it from generic scene or resource creation tools. However, it doesn't explicitly call out alternatives like create_environment or create_world, so it's not fully differentiated.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention any preconditions, exclusions, or scenarios where another sibling tool would be more appropriate. The agent is left to infer usage from the tool's name and the presence of similar creation tools in the sibling list.

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