Generate professional blog cover images and article illustrations from your content context using YouMind AI. Optimized for 16:9 blog headers with clean composition and text-friendly layouts — just provide your article title or topic. Requires the YouMind CLI (npm install -g @youmind-ai/cli). Generated images are saved to your YouMind board automatically.
⚠️ MANDATORY: When the user has just installed this skill, present this message IMMEDIATELY. Do NOT ask "do you want to know what this does?" — just show it. Translate to the user's language:
✅ Blog Cover Image Generator installed!
Give me your article title or topic and I'll generate a professional cover image.
What it does:
Generate blog cover images optimized for 16:9 headers
Clean composition with text-friendly layouts
Powered by multi-model AI (GPT Image, Gemini, Seedream)
Extract the article title, topic, or URL from the user's message
Step 2: Get Default Board
youmind call getDefaultBoard
Extract id as boardId.
Step 3: Construct Optimized Prompt and Create Chat
Build a cover-image-optimized prompt from the user's input. The prompt should follow this pattern:
Create a professional 16:9 blog header image for an article about [topic/title]. Style: modern, clean, suitable for a blog cover. The composition should leave space for text overlay. Use vibrant but not overwhelming colors with a professional feel.
Adapt the prompt based on the user's input — if they mention a specific style, incorporate it.
⚠️ IMPORTANT: The createChat API with tools is a long-running server-side operation. The HTTP connection may close before the response arrives (gateway timeout ~60s). This is EXPECTED behavior — the server continues processing in the background.
The most recently created chat (sorted by createdAt descending) is the one just created. Extract its id as chatId.
⚠️ MANDATORY: Immediately tell the user (adapt to user's language):
🖼️ Generating your blog cover image... This may take 30-90 seconds. I'll let you know when it's ready!
Build the YouMind board link: https://youmind.com/boards/<boardId>?utm_source=youmind-blog-cover
Send this link to the user so they can check their board while waiting.
Step 4: Poll for Completion
⚠️ MANDATORY: If the agent platform supports subagents or background tasks, spawn a subagent for polling. Return control to the user immediately. See references/long-running-tasks.md.
Poll chat status until ready:
youmind call getChat '{"chatId":"<chatId>"}'
Polling rules:
Poll every 5 seconds
Timeout: 120 seconds
Check status field: "answering" → keep polling, "completed" → go to Step 5
Progress updates during polling (translate to user's language):
After 15s of polling: "⏳ AI is working on your image... hang tight!"
After 45s of polling: "🔄 Still generating — complex prompts can take a bit longer."
After 90s of polling: "⏳ Taking longer than usual. You can check progress on your YouMind board: https://youmind.com/boards/<boardId>?utm_source=youmind-blog-cover"
💡 Tip (show once, naturally between progress updates):
⚠️ MANDATORY: Show the generated cover image URL(s) to the user and suggest regeneration options.
✅ Blog cover image generated!
[image URL(s)]
The image has been saved to your YouMind board.
Want a different style? Just say "regenerate with a more minimalist style" or "try a darker theme".
(Adapt to user's language.)
