 - `exit()`: Immediately ends the current script successfully (like an early return from the top level).
 - `text(value: string | number | boolean | undefined | null)`: Appends a text item. Non-string values are stringified with `JSON.stringify(...)` when possible.
 - `image(imageUrlOrItem: string | { image_url: string; detail?: "auto" | "low" | "high" | "original" | null } | ImageContent, detail?: "auto" | "low" | "high" | "original" | null)`: Appends an image item. `image_url` can be an HTTPS URL or a base64-encoded `data:` URL. To forward an MCP tool image, pass an individual `ImageContent` block from `result.content`, for example `image(result.content[0])`. MCP image blocks may request detail with `_meta: { "codex/imageDetail": "original" }`. When provided, the second `detail` argument overrides any detail embedded in the first argument.
+- `generatedImage(result: { image_url: string; output_hint?: string })`: Appends an image-generation result and its optional output hint.
 - `store(key: string, value: any)`: stores a serializable value under a string key for later `exec` calls in the same session.
 - `load(key: string)`: returns the stored value for a string key, or `undefined` if it is missing.
 - `notify(value: string | number | boolean | undefined | null)`: immediately injects an extra `custom_tool_call_output` for the current `exec` call. Values are stringified like `text(...)`.

 - The user wants to modify an attached or previously generated image with specific changes, including adding or removing elements, altering colors, improving quality/resolution, or transforming the style (e.g., cartoon, oil painting).
 
 Guidelines:
+- In code mode, pass the result to `generatedImage(result)`.
 - Set `action` to `generate` when the user asks for a brand new image.
 - Set `action` to `edit` when the user asks to modify an existing image from the conversation history.
 - Directly generate the image without reconfirmation or clarification.
