x3dom_starter

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

With no annotations, the description carries full transparency burden. It discloses that the tool returns a ready-to-open HTML file, loads X3DOM from CDN, includes a simple 3D scene (red cube, lighting, viewpoint), and clean styling. This is useful behavioral context, though it does not mention caveats like internet/CDN availability.

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 two sentences, front-loaded with the core purpose, and every sentence earns its place by explaining what is generated and how to use the output. No filler or redundancy.

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 zero-parameter generator with an output schema, the description is complete: it states the purpose, the exact contents of the generated file, and the follow-up action ('Save the output as an .html file and open it'). No important context is missing.

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 tool has zero parameters, so the baseline is 4. The description adds no parameter-level details because there are none to describe, and the schema already indicates no arguments are 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 clearly states a specific verb ('Generate') and resource ('complete starter X3DOM HTML page with an example scene'). It is specific about the output, but it does not explicitly distinguish itself from sibling tools like 'x3dom_page' or 'x3d_scene_template', so it falls slightly short of full sibling differentiation.

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 mentions saving the output and opening it in a browser, but there is no indication of preferred use cases or exclusions relative to the many sibling tools.

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