create_world

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Create World3D .tres.' only states the action itself and does not disclose whether the tool overwrites existing files, creates directories, requires additional setup, or has side effects. This is a significant transparency gap for a file creation tool.

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 extremely short (four words), which is concise but under-specified. It does not include essential context about behavior, usage, or side effects, making it an example of under-specification rather than effective conciseness. A single terse sentence is not appropriately sized for a tool with no annotations.

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?

Despite having complete schema coverage for parameters, the description lacks any contextual information about the World3D resource, when to use this tool, or what happens after creation. With no annotations and no output schema, the description should provide more context but instead offers only a bare statement, leaving the agent without sufficient understanding of the tool's behavior and implications.

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%, with both parameters (path and environment_path) described clearly in the input schema. The description itself adds no parameter information, so it does not exceed the baseline. The baseline of 3 applies because the schema fully documents the parameters.

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 'Create World3D .tres.' states a specific verb (create) and resource (World3D .tres file), which clearly identifies the tool's function. It distinguishes itself from sibling tools like create_environment and create_world_environment by specifying the exact resource type and file extension.

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 provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, exclusions, or comparison to similar tools such as write_resource or create_resource. The intended usage is only implied by the tool name.

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