Image Generation Agent

What This Tool Does

AI image generator powered by Google Gemini 3 Flash Image and "Nano Banana". Create photorealistic product photography, marketing creative, social graphics, app icons, concept art, hero images, and brand assets from a single text prompt — or edit an existing image by passing up to four reference photos for style, subject, or scene guidance. Choose your output tier: a low-cost budget draft for ideation, or crisp 0.5K, 1K, 2K, and 4K final renders for print, ads, e-commerce, and presentation use. Supports 14 aspect ratios including 1:1, 16:9, 9:16, 21:9, 4:5, and ultra-wide 8:1 banner formats. Every generated image is auto-saved to AgentPMT File Manager with a 7-day signed download URL, file_id, width, height, MIME type, and size bytes — ready to drop into chat, hand off to another tool, or pull into a workflow. Built for designers, marketers, e-commerce sellers, content creators, and AI agents that need on-demand visuals without leaving the conversation.

Product Instructions

AI Image Creator

Create images from prompts, or edit an image by adding reference images. Generated images are saved to File Manager and returned with a signed URL that users can open or download directly, plus file_id, MIME type, size, width, and height.

Choosing an action

generate_budget_image: Lower-cost drafts, previews, simple assets, or 1024px-class output.
generate_image_0_5k: Small high-efficiency output.
generate_image_1k: Standard final images.
generate_image_2k: Higher-resolution social, presentation, or product assets.
generate_image_4k: Highest-resolution final assets.

Inputs

prompt is required for every generation action.
aspect_ratio defaults to 1:1.
reference_images is optional and accepts up to 4 images.
Reference image formats: PNG, JPEG, or WebP.
Reference image sources:
- {"source_kind":"file_id","file_id":"<file-id>"}
- {"source_kind":"url","url":"https://example.com/image.png"}
- {"source_kind":"base64","base64_data":"<base64>","mime_type":"image/png"}
filename is optional. The final extension is inferred from the generated image.
expiration_days defaults to 7 and must be from 1 to 7.
Generated image bytes are not returned inline. Use the signed URL to open or download the file.

Only use reference images you have the right to use.

Aspect ratios

generate_budget_image supports: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9.

High-resolution actions support: 1:1, 1:4, 1:8, 2:3, 3:2, 3:4, 4:1, 4:3, 4:5, 5:4, 8:1, 9:16, 16:9, 21:9.

Live Schema And Examples

Use the compact schema above for ordinary calls. Before a new production integration, or whenever parameters, enum values, nested objects, outputs, or examples are unclear, fetch live details first.

Exact schema: call agentpmt-tool-search-and-execution with action: "get_schema", and tool_id: "image-generation-agent".
Detailed examples: call agentpmt-tool-search-and-execution with action: "get_instructions" and tool_id: "image-generation-agent", or call this product with action: "get_instructions" when the product tool is already selected.
Treat returned live schema and instructions as more specific than this generated summary.

MCP schema lookup through the main AgentPMT MCP server:

{
  "method": "tools/call",
  "params": {
    "name": "AgentPMT-Tool-Search-and-Execution",
    "arguments": {
      "action": "get_schema",
      "tool_id": "image-generation-agent"
    }
  }
}

For live examples, keep the same MCP tool and use these arguments:

{
  "action": "get_instructions",
  "tool_id": "image-generation-agent"
}

REST lookup body with an AgentPMT Bearer Token:

{
  "name": "agentpmt-tool-search-and-execution",
  "parameters": {
    "action": "get_schema",
    "tool_id": "image-generation-agent"
  }
}

Response Handling

Treat the returned JSON as the source of truth for this tool call.
If the response includes warnings or correction targets, apply them before retrying.
If the response includes a passed or success-style boolean, use it as the workflow gate.
If validation fails or the response shape is unclear, call get_schema or get_instructions before retrying.
If generate_budget_image fails, preserve the request parameters and retry only after fixing schema, auth, or payment errors.

Security

Do not place Bearer Tokens, wallet private keys, mnemonics, signatures, or payment headers in prompts or logs.
Keep tool inputs scoped to the minimum content needed for the task.
Use the setup skills for credential handling; this product skill only defines product-specific behavior.
