This skill handles text-to-image and image-to-image (edit) generation. The script uses the **async API** (`/v1/async/images/...`) — it submits the job, polls until completion, and prints the final URL. This avoids the 100s Cloudflare edge timeout that 2K/4K renders used to hit. A single call may take up to ~5 minutes for heavy renders; no extra flags needed. ## 1. Environment check Before generating, verify the token is set: ```bash if [ -z "$LETMEGO_API_KEY" ]; then echo "❌ LETMEGO_API_KEY is not set." echo "Visit https://api.letmego.top to get your 令牌, then:" echo " export LETMEGO_API_KEY=your_token" exit 1 fi ``` ## 2. Gather parameters Ask the user if not already provided: | Parameter | Options | Default | |-----------|---------|---------| | `prompt` | any text description | *(required)* | | `quality` | `1k` · `2k` · `4k` | `1k` | | `aspect` | `square` · `landscape` · `portrait` | `square` | | `n` | 1 – 10 | `1` | | `ref` | local file path (optional) | *(none → text-to-image)* | **Quality guide:** - `1k` — up to 1536×1536, fast and cheap, great for previews and social media - `2k` — up to 2048×2048, suitable for e-commerce and print - `4k` — up to 3840×2160, landscape or portrait only (no 4k square) ## 3. Locate and run the generation script ```bash # Resolve skill directory (user-global → project-local) SKILL_DIR="$HOME/.claude/skills/picnow" [ -d "$SKILL_DIR" ] || SKILL_DIR=".claude/skills/picnow" node "$SKILL_DIR/scripts/generate.js" \ --prompt "PROMPT_HERE" \ --quality QUALITY \ --aspect ASPECT \ --n N # add: --ref /path/to/image.jpg for image-to-image ``` The script outputs a single JSON line: ```json { "urls": ["https://...cdn.../image.png"] } ``` ## 4. Present results - Display each URL as a clickable link or inline image. - For multiple images, list them with index labels (1/3, 2/3, …). - Offer to download, save to a project, or run another variation. ## Error handling | Exit condition | Meaning | Action | |---|---|---| | `LETMEGO_API_KEY` missing | Token not set | Guide user to picnow settings | | HTTP 401 | Token invalid | Ask user to check or refresh token | | HTTP 402 / quota | Insufficient balance | Direct to letmego.top recharge | | HTTP 4xx other | Bad request | Show upstream error message | | Network error | Connection issue | Suggest retry | ## Examples **Text-to-image:** ``` User: 帮我画一张珠宝产品主图，白色背景，高清 → quality=2k, aspect=square → node "$SKILL_DIR/scripts/generate.js" \ --prompt "jewelry product hero shot, white background, studio lighting, photorealistic" \ --quality 2k --aspect square --n 1 ``` **Image-to-image:** ``` User: 把这张图改成动漫风格 [uploads reference.jpg] → quality=1k, ref=reference.jpg → node "$SKILL_DIR/scripts/generate.js" \ --prompt "anime style illustration, vibrant colors, clean linework" \ --quality 1k --aspect square --n 1 --ref reference.jpg ``` **Landscape banner:** ``` User: Generate a landscape banner for a coffee brand → quality=1k, aspect=landscape, n=2 → node "$SKILL_DIR/scripts/generate.js" \ --prompt "coffee brand lifestyle banner, warm tones, morning light, artisan aesthetic" \ --quality 1k --aspect landscape --n 2 ```
