Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| configure_gemini_tokenA | Configure your Gemini API token for nano-banana image generation |
| generate_imageA | Generate a NEW image from text prompt. Use this ONLY when creating a completely new image, not when modifying an existing one. |
| edit_imageA | Edit a SPECIFIC existing image file, optionally using additional reference images. Use this when you have the exact file path of an image to modify. |
| get_configuration_statusA | Check if Gemini API token is configured |
| continue_editingA | Continue editing the LAST image that was generated or edited in this session, optionally using additional reference images. Use this for iterative improvements, modifications, or changes to the most recent image. This automatically uses the previous image without needing a file path. |
| get_last_image_infoA | Get information about the last generated/edited image in this session (file path, size, etc.). Use this to check what image is currently available for continue_editing. |

Scored across 6 tools
Each tool has a clearly distinct purpose: configuration, generation, file-specific editing, last-image editing, status check, and info retrieval. The descriptions explicitly clarify boundaries, especially between edit_image (specific file) and continue_editing (last image).
All tool names follow a consistent verb_noun pattern in snake_case (configure_gemini_token, generate_image, edit_image, get_configuration_status, continue_editing, get_last_image_info). Minor variation like 'continue_editing' still starts with a verb, maintaining a predictable style.
With 6 tools, the set is well-scoped for an image generation/editing server. It covers configuration, creation, editing, iteration, and status/info queries without unnecessary bloat or missing essentials.
The core lifecycle is covered: configure, generate, edit, continue editing, and retrieve info. Minor gaps exist, such as no explicit list or delete operations for generated images, but these are peripheral to the primary generation/editing workflow.
