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

Annotations indicate a non-read-only, non-idempotent operation, but the description adds no behavioral context such as polling behavior, cost, or output format. The sentence 'let AI refine them into entirely original masterpieces' is vague and not informative about how the tool operates.

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 verbose and promotional, with fragmented sections like 'Want more inspirations? Please refer to', 'Use cases:', and 'Sample output:' that are left empty. It is not front-loaded and contains no concrete technical information, making it largely filler.

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?

Despite having a nested request object, a polling parameter, and an output schema, the description fails to explain the asynchronous behavior, return values, or how to construct a valid request. The incomplete 'Use cases' and 'Sample output' sections leave the agent without essential context.

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 description does not mention any of the parameters (polling, request, prompt, size, etc.) and fails to compensate for the 50% schema coverage. The schema itself provides some descriptions, but the description contributes zero parameter semantics.

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 marketing language like 'text-to-image generator' and 'transform your ideas into stunning visuals' rather than a clear verb+resource statement. It also mentions 'Add images as references,' which is not supported by the input schema and blurs the boundary with the sibling tool AI-Image-Generator-Image-to-Image.

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?

There is no guidance on when to use this tool over alternatives. The description mentions generic creative audiences but provides no explicit when-to-use or when-not-to-use scenarios, nor does it reference any of the many sibling image/video generation tools.

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