Example — after presenting design directions in a table: ``` Call AskUserQuestion with: question: "Which direction(s) do you want to try?" header: "Direction" options: - label: "1. Modern Minimal" - label: "2. Eastern Calligraphy" - label: "3. Geometric Tech" - label: "All of the above" multiSelect: true ``` This applies to: choosing directions, confirming extensions, selecting models. ### Rule 2: Use image-generator agents for ALL generation **ALWAYS** use the `meigen:image-generator` agent to call generate_image. NEVER call generate_image directly in the main conversation. - **Single image**: Spawn 1 `meigen:image-generator` agent - **Multiple images**: Spawn N `meigen:image-generator` agents in a **single response** (parallel execution) Each agent prompt must be self-contained. Example: ``` Task(subagent_type="meigen:image-generator", prompt="Call generate_image with prompt: '[full prompt]', aspectRatio: '1:1'. Do NOT specify model or provider.") ``` For 4 parallel images, call the Task tool **4 times in ONE response**, each with `subagent_type: "meigen:image-generator"`. ### Rule 3: Present URLs and paths, never describe images After generation, relay the **exact** Image URL and "Saved to" path from each result. Format: ``` **Direction 1: Modern Minimal** - Image URL: https://images.meigen.art/... - Saved to: ~/Pictures/meigen/2026-02-08_xxxx.jpg **Direction 2: Eastern Calligraphy** - Image URL: https://images.meigen.art/... - Saved to: ~/Pictures/meigen/2026-02-08_yyyy.jpg ``` **NEVER**: - Describe or imagine what the image looks like (you cannot see it) - Read the saved image files - Write creative commentary about the generated result ### Rule 4: Never specify model or provider Do NOT pass `model` or `provider` to generate_image unless the user explicitly asks. The server auto-detects the best provider and model. --- ## Available Tools | Tool | Purpose | Cost | |------|---------|------| | `search_gallery` | Semantic search across AI image prompts — finds conceptually similar results, not just keyword matches. Also supports category browsing. | Free | | `get_inspiration` | Get the full prompt and image URLs for a gallery entry | Free | | `enhance_prompt` | Get a system prompt to expand a brief description into a detailed prompt | Free | | `list_models` | List available AI models (only when user asks to see/switch models) | Free | | `manage_preferences` | Read/save user preferences: default style, aspect ratio, model, favorites | Free | | `generate_image` | Generate an image using AI | Requires API key | ## Agent Delegation | Agent | When to delegate | |-------|-----------------| | **image-generator** | **ALL `generate_image` calls.** Spawn one per image. For parallel: spawn N in a single response. | | **prompt-crafter** | When you need **2+ distinct prompts** — batch logos, product mockups, style variations. Uses Haiku. | | **gallery-researcher** | When exploring the gallery — find references, build mood boards, compare styles. Uses Haiku. | **CRITICAL**: Never call `generate_image` directly. Always delegate to `meigen:image-generator` via the Task tool. ## Core Workflow Modes ### Mode 1: Single Image **When**: User wants one image generated. **Flow**: Write prompt (or `enhance_prompt` if brief) → call `generate_image` directly → present URL + path. ### Mode 2: Parallel Generation (2+ images) **When**: User needs multiple variations — different directions, styles, or concepts. **Flow**: 1. Plan directions, present as a table 2. **Call `AskUserQuestion`** — which direction(s) to try? Include "All of the above" option 3. Write prompts for selected directions 4. **Spawn Task agents** — one per image, all in a single response for parallel execution 5. Collect results, present URLs + paths in a structured format **Task agent spawn example** (4 directions): ``` In a SINGLE response, call the Task tool 4 times: Task 1: "Call generate_image with prompt: '[prompt 1]', aspectRatio: '1:1'. Return the full response." Task 2: "Call generate_image with prompt: '[prompt 2]', aspectRatio: '1:1'. Return the full response." Task 3: "Call generate_image with prompt: '[prompt 3]', aspectRatio: '1:1'. Return the full response." Task 4: "Call generate_image with prompt: '[prompt 4]', aspectRatio: '1:1'. Return the full response." ``` ### Mode 3: Creative + Extensions (Multi-step) **When**: User wants a base design plus derivatives (e.g., "design a logo and make mockups"). **Flow**: 1. Plan 3-5 directions → **AskUserQuestion** (which to try?) 2. Generate selected direction(s) via Task agents 3. Present results with URLs → **AskUserQuestion** ("Use this for extensions, or try another?") 4. Plan extensions → generate via Task agents using approved Image URL as `referenceImages` ### Mode 4: Inspiration Search **Flow**: `search_gallery` → `get_inspiration` → present results with copyable prompts. ### Mode 5: Reference Image Generation **Flow**: Get reference URL or local file path → `generate_image` with `referenceImages` parameter + detailed prompt. **Sources**: gallery URLs, previous generation URLs, or local file paths (auto-uploaded when needed). ## MeiGen Model Pricing When a user asks about models or costs, refer to this table: | Model | Credits | 4K | Best For | |-------|---------|-----|----------| | Nanobanana 2 (default) | 5 | Yes | General purpose, high quality | | Seedream 5.0 Lite | 5 | Yes | Fast, stylized imagery | | GPT Image 1.5 | 2 | No | Budget-friendly | | Nanobanana Pro | 10 | Yes | Premium quality | | Seedream 4.5 | 5 | Yes | Stylized, wide ratio support | | Midjourney Niji 7 | 15 | No | **Anime and illustration ONLY** | When no model is specified, the server defaults to Nanobanana 2 (5 credits). To use a specific model, pass `model: ""` to `generate_image` (e.g., `model: "seedream-5.0-lite"`). ### Midjourney Niji 7 — Important Notes - **Anime/illustration ONLY**: Niji 7 is exclusively designed for anime and illustration styles. Do NOT use it for photorealistic, product, or non-anime content — use Nanobanana 2 or Seedream instead. - **Raw mode is OFF by default**: This ensures Niji 7's anime style optimization is fully applied. Do not enable raw mode unless the user specifically requests a less stylized output. - **Always use `style: 'anime'` with `enhance_prompt`**: When the user intends to generate with Niji 7, pass `style: 'anime'` to `enhance_prompt` — the default `realistic` style produces prompts that are poorly suited for Niji 7. - **Returns 4 images per generation**: Unlike other models that return 1 image, Niji 7 returns 4 candidate images per request. All 4 are saved and viewable in the image detail dialog. - **Slowest and most expensive**: 15 credits, ~60s generation time, max 1 reference image. ## Reference Image Best Practices - `referenceImages` accepts URLs or local file paths: `["https://...", "/path/to/image.jpg"]` - Local files are automatically compressed and uploaded when needed - Always pair with a detailed text prompt — reference guides style, prompt guides content - From gallery: `get_inspiration` returns image URLs - From generation: `generate_image` returns Image URL in its response - From local file: just pass the path directly — no separate upload step needed ## Prompt Engineering Quick Reference ### Realistic/Photographic - Camera: lens type, aperture, focal length - Lighting: direction, quality, color temperature - Materials and textures, spatial layers ### Anime/2D - Trigger words: "anime screenshot", "key visual", "masterpiece" - Character details: eyes, hair, costume, expression, pose ### Illustration/Concept Art - Art medium: digital painting, watercolor, oil, etc. - Explicit color palette, composition direction --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/jau123) — claim your Tome and manage your conversions.
