kie_generate_image

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

No annotations are present, so the description must disclose behavior. It only states a high-level action; it doesn't mention that generation may be asynchronous (suggested by kie_check_task), how the output is returned/saved, or any rate limits or cost implications.

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 a single sentence with no wasted words. However, it sacrifices substance for brevity, not explaining the tool's behavior beyond a basic action.

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 tool with 8 parameters and no output schema, this description is minimal. It omits the generation workflow (likely returning a task to check via kie_check_task), output file handling (referenced in output_dir), and model selection, leaving the agent under-informed.

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 input schema already describes all 8 parameters with 100% coverage. The description adds no parameter-specific semantics, leaving the schema to do the heavy lifting, so a baseline score of 3 is appropriate.

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 ('Generate') and resource ('an image'), clearly distinguishing this tool from siblings like kie_generate_video and kie_generate_audio. The phrase 'via kie.ai' adds provider context, which is redundant but not harmful.

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 is provided on when to use this tool versus alternatives. It does not mention asynchronous tasks, prerequisites, or when to prefer kie_generate_video or kie_upscale.

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