Rd Texture Gen

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

With no annotations, the description carries the full behavioral disclosure burden. It explains that PBR maps are generated and lists tiling modes, but does not disclose whether files are written, whether a backend must be running, what happens to inputs, or how results are returned.

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?

Extremely concise: one core sentence plus a one-line tiling summary. All content is front-loaded and every phrase earns its place.

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?

The tool is simple with only two parameters and an output schema exists, so the description is close to minimally viable. Still, without annotations it leaves behavioral gaps—such as side effects and prerequisites—that an agent would need to invoke it safely.

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 coverage is 0%, so the description must compensate. It adds meaning for tiling by enumerating its values, and 'from images' loosely maps to image_paths. However, it does not clarify path formats, accepted image types, or whether tiling defaults apply per map.

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?

States a specific verb and resource: generate PBR textures (normal/roughness/displacement) from images. This clearly distinguishes it from generic siblings like rd_generate and rd_img2img by naming the exact output type.

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?

No guidance on when to use this tool versus alternatives like rd_generate or rd_img2img, and no exclusions or prerequisites are mentioned. The intended use is implied by the name and description, but not explicitly stated.

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