create_scene

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

With no annotations, the description must disclose behavioral traits. It states the file is created on disk and the editor is not opened. However, it does not mention overwrite behavior, error handling (e.g., if the file exists), or permission requirements. These are important for a file-creating 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 a single, efficient sentence that starts with the action and includes all necessary differentiators. There is zero wasted wording.

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 simple file-creation tool, the description covers the core behavior but omits edge-case details like file existence handling, path resolution, and the purpose of root_name. It is adequate for basic use but not fully complete given the lack of annotations and output schema.

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 all parameters. It only hints at 'root node type' (root_type) but provides no explanation of the required 'path' or the optional 'root_name'. This leaves significant ambiguity for the agent.

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 uses a specific verb 'create' with a clear resource 'scene file on disk' and a key differentiator 'without opening it in the editor'. It distinguishes itself from sibling tools like open_scene or save_scene. The purpose is unambiguous.

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 clearly implies when to use this tool (when you need to create a scene file without opening it). However, it does not explicitly state when not to use it or name alternative tools, so it lacks the explicit exclusions needed for a 5.

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