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. It does not explain that the tool requires pre-uploaded images, that it returns a generated image URL, or that polling may be needed. It even misrepresents the core behavior by calling it text-to-image.

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 padded with promotional fluff and ends with incomplete, meaningless placeholders ('Want more inspirations? Please refer to Use cases: Sample output:'). Every sentence is vague and none provide concrete, actionable information, making this poor structure rather than concise.

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?

Given the tool's complexity—nested anyOf request schema, polling flag, multiple image-input options, and many sibling tools—the description is entirely inadequate. It omits the core editing use case, prerequisites, and expected output, leaving an agent without the context needed to select and invoke 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 schema provides detailed parameter descriptions, but the top-level description adds no orientation for the required 'request' object, the dual src_file_urls/src_file_ids alternatives, or the polling parameter. At 50% schema coverage, the description should help compensate, but it only vaguely mentions prompts and reference images without mapping them to actual parameters.

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 explicitly calls the tool a 'text-to-image generator', which contradicts its image-to-image purpose. It relies on vague marketing phrases like 'discover the power of AI' and 'endless possibilities' without ever stating that it edits reference images based on a prompt, and it fails to distinguish itself from the sibling Text-to-Image tool.

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 usage guidance is provided. The description targets generic audiences ('artist, designer, or creative soul') but does not say when to choose this tool over siblings like AI-Image-Generator-Text-to-Image, AI-Face-Swap, or AI-Replace, nor does it mention any prerequisites or exclusion criteria.

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