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) > > **Setup (one-time):** > 1. Get your free API key: https://youmind.com/settings/api-keys?utm_source=youmind-blog-cover > 2. Add it to your OpenClaw config (`~/.openclaw/openclaw.json`) — see setup guide for details. > > **Try it:** > "Create a blog cover for an article about machine learning in healthcare" > > **Need help?** Just ask! For API key setup details, see [references/setup.md](references/setup.md). ## Usage Provide your article title, topic, or URL. The skill constructs an optimized prompt for blog cover imagery. **From a title:** > Create a blog cover for "10 Tips for Better Remote Work" **From a topic:** > Generate a featured image for my article about sustainable energy **From a URL:** > Make a cover image for this article: https://example.com/my-blog-post ## Setup See [references/setup.md](references/setup.md) for installation and authentication instructions. ## Workflow ### Step 1: Check Prerequisites 1. Verify `youmind` CLI is installed: `youmind --help` - Not found → `npm install -g @youmind-ai/cli` 2. Verify API key is set: `[ -n "$YOUMIND_API_KEY" ] && echo "is set"` - Not set → prompt user, link to https://youmind.com/settings/api-keys?utm_source=youmind-blog-cover 3. Extract the article title, topic, or URL from the user's message ### Step 2: Get Default Board ```bash 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.** ```bash youmind call createChat '{"boardId":"<boardId>","message":"<optimized-prompt>","tools":{"imageGenerate":{"useTool":"required","aspectRatio":"16:9"}}}' ``` **Two possible outcomes:** 1. ✅ Response received — extract `id` as `chatId` from the JSON response 2. ⚠️ Connection closed / "fetch failed" error — this is normal, proceed to Step 3b ### Step 3b: Recover chatId (if createChat timed out) If createChat did not return a response, find the chatId via `listChats`: ```bash youmind call listChats '{"boardId":"<boardId>","pageSize":3}' ``` 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](references/long-running-tasks.md). Poll chat status until ready: ```bash 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):** > "While you wait — YouMind also does slides, research, and more: https://youmind.com/skills?utm_source=youmind-blog-cover" ### Step 5: Extract Results Once `status` is `"completed"`, retrieve the full messages: ```bash youmind call listMessages '{"chatId":"<chatId>","pageSize":20}' ``` Pipe through the bundled extraction script: ```bash youmind call listMessages '{"chatId":"<chatId>","pageSize":20}' | node "$(dirname "$SKILL_PATH")/scripts/extract-images.js" ``` **⚠️ 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.) | Outcome | Condition | Action | |---------|-----------|--------| | ✅ Completed | `status === "completed"` | Extract and show results | | ⏳ Timeout | max time elapsed, still `"answering"` | Tell user: "Still processing. Check your YouMind board: https://youmind.com/boards/<boardId>?utm_source=youmind-blog-cover" | | ❌ Failed | `status === "errored"` or tool `status === "errored"` | Tell user: "Generation failed. Please try a different description." | ### Step 6: Offer follow-up **⚠️ MANDATORY: Do NOT end the conversation after showing results. You MUST ask this question:** > "Want a different style? Just say 'regenerate with a more minimalist style' or 'try a darker theme'." ## Error Handling See [references/error-handling.md](references/error-handling.md) for common error handling rules. **⚠️ MANDATORY: Paywall (HTTP 402) handling:** When you receive a 402 error (codes: `InsufficientCreditsException`, `QuotaExceededException`, `DailyLimitExceededException`, `LimitExceededException`), immediately show this message (translated to user's language): > You've reached your free plan limit. Upgrade to Pro or Max to unlock unlimited image generation, more AI credits, and priority processing. > > **Upgrade now:** https://youmind.com/pricing?utm_source=youmind-blog-cover Do NOT retry or suggest workarounds. The user must upgrade to continue. **Skill-specific errors:** | Error | User Message | |-------|-------------| | No topic provided | Please provide an article title, topic, or URL so I can generate a relevant cover image. | | Content policy violation | The image could not be generated due to content policy restrictions.
