fusion_export_f3d

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

Annotations indicate readOnlyHint=false and openWorldHint=true, suggesting potential side effects. The description adds only that it 'preserves the full design tree' but does not disclose where the file is saved, whether it overwrites, or any other behavioral traits beyond what annotations already suggest.

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 sentence, which is concise and front-loaded, but it is too brief given the tool's context, lacking necessary details about parameters and usage.

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?

With one optional parameter, no output schema, and many sibling export tools, the description only covers purpose. It fails to explain parameter behavior, return value, or provide enough context for an agent to use the tool correctly.

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 only parameter 'path' is optional with default null, and the schema coverage is 0%. The description provides no explanation of what the path does, what happens if null, or expected format, failing to compensate for the lack of schema descriptions.

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 verb 'Export' and the resource 'native Fusion archive (.f3d)', and distinguishes it from other export tools by mentioning 'preserving the full design tree', which indicates a specific use case not covered by sibling export tools.

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 usage when a native Fusion archive is needed, but does not provide explicit guidance on when to use this tool versus alternatives like fusion_export_step or fusion_export_stl, nor does it mention when not to use it.

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