ue_x3d_preview

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

Annotations already indicate readOnlyHint and idempotentHint. The description adds useful context: the output is a standalone HTML referencing X_ITE from CDN, requiring network access, and the X3D payload is embedded inline. No contradiction.

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?

Two succinct sentences with no wasted words. Every sentence adds value: first states the core action and output format, second provides a network dependency caveat.

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 tool, the description covers key aspects: input, output structure, and runtime requirement. The presence of an output schema reduces the burden, though the output is also described. A minor gap is not specifying the X3D format (e.g., XML, JSON) expected.

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?

With 0% schema description coverage, the description should compensate. It only vaguely mentions 'an X3D document' for the required 'x3d' parameter and doesn't explain the 'title' parameter beyond its default value. More detail on content format or usage is needed.

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 ('render') and resource ('X3D document'), clearly distinguishing it from sibling tools like ue_x3d_apply, ue_x3d_export, and ue_x3d_validate. The phrase 'no editor needed' adds clarity.

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 use for previewing X3D documents but lacks explicit guidance on when to use or avoid this tool. No alternatives or exclusions are mentioned.

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