generate_image

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

With no annotations provided, the description carries full burden but offers minimal behavioral context. It mentions the model (Ideogram V3 Balanced) and API (Replicate) but doesn't disclose rate limits, authentication needs, cost implications, output format, generation time, or error handling. The three modes are listed but not explained operationally.

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 appropriately brief (two sentences) and front-loaded with the core purpose. Every sentence adds value: the first establishes the tool's function and context, the second enumerates capabilities. No wasted words or redundant information.

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 complex 10-parameter image generation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what the tool returns (image URL? binary data?), how to handle the output, error conditions, or important behavioral aspects like generation time or cost. The three modes are mentioned but not sufficiently contextualized.

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 description coverage is 100%, providing comprehensive parameter documentation. The description adds minimal value beyond the schema, only implying that 'prompt' is for text-to-image and that 'image' and 'mask' relate to inpainting. It doesn't explain parameter interactions or provide usage examples.

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 the tool generates images using a specific model and API, and lists three supported modes (text-to-image, inpainting, style transfer). It distinguishes from the sibling 'get_image_status' by focusing on creation rather than status checking, though it doesn't explicitly contrast them.

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 mentions three use cases (text-to-image, inpainting, style transfer) but provides no guidance on when to choose one over another, prerequisites for inpainting (requires mask), or alternatives. It doesn't explain when this tool should be used versus other image generation tools that might exist.

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