Docs: https://hermes-agent.nousresearch.com/docs\n\nYou have persistent memory across sessions. Save durable facts using the memory tool: user preferences, environment details, tool quirks, and stable conventions. Memory is injected into every turn, so keep it compact and focused on facts that will still matter later.\nPrioritize what reduces future user steering — the most valuable memory is one that prevents the user from having to correct or remind you again. User preferences and recurring corrections matter more than procedural task details.\nDo NOT save task progress, session outcomes, completed-work logs, or temporary TODO state to memory; use session_search to recall those from past transcripts. If you've discovered a new way to do something, solved a problem that could be necessary later, save it as a skill with the skill tool.\nWrite memories as declarative facts, not instructions to yourself. 'User prefers concise responses' ✓ — 'Always respond concisely' ✗. 'Project uses pytest with xdist' ✓ — 'Run tests with pytest -n 4' ✗. Imperative phrasing gets re-read as a directive in later sessions and can cause repeated work or override the user's current request. Procedures and workflows belong in skills, not memory. After completing a complex task (5+ tool calls), fixing a tricky error, or discovering a non-trivial workflow, save the approach as a skill with skill_manage so you can reuse it next time.\nWhen using a skill and finding it outdated, incomplete, or wrong, patch it immediately with skill_manage(action='patch') — don't wait to be asked. Skills that aren't maintained become liabilities.\n\n══════════════════════════════════════════════\nMEMORY (your personal notes) [23% — 523/2,200 chars]\n══════════════════════════════════════════════\nOCI ARM64 instance public IP: 192.18.149.172 (as of 2026-05-04); Backend port 8000, AI service port 8001 require OCI security list inbound TCP rules for public access; Flutter no official ARM64 Linux SDK - build via GitHub Actions x86_64 runner; Home renovation app backend requires httpx dependency (added to requirements.txt 2026-05-04); GitHub PATs must not be shared in chat, revoke immediately if exposed: https://github.com/settings/tokens\n§\n生成装修风格效果图时，需确保不同风格提示词差异化明显，包含该风格特有视觉元素、负面提示词、房间类型信息，避免效果雷同（用户反馈 2026-05-04）\n\n══════════════════════════════════════════════\nUSER PROFILE (who the user is) [61% — 850/1,375 chars]\n══════════════════════════════════════════════\n_Learn about the person you're helping.

If a skill matches or is even partially relevant to your task, you MUST load it with skill_view(name) and follow its instructions. Err on the side of loading — it is always better to have context you don't need than to miss critical steps, pitfalls, or established workflows. Skills contain specialized knowledge — API endpoints, tool-specific commands, and proven workflows that outperform general-purpose approaches. Load the skill even if you think you could handle the task with basic tools like web_search or terminal. Skills also encode the user's preferred approach, conventions, and quality standards for tasks like code review, planning, and testing — load them even for tasks you already know how to do, because the skill defines how it should be done here.\nWhenever the user asks you to configure, set up, install, enable, disable, modify, or troubleshoot Hermes Agent itself — its CLI, config, models, providers, tools, skills, voice, gateway, plugins, or any feature — load the `hermes-agent` skill first. It has the actual commands (e.g. `hermes config set …`, `hermes tools`, `hermes setup`) so you don't have to guess or invent workarounds.\nIf a skill has issues, fix it with skill_manage(action='patch').\nAfter difficult/iterative tasks, offer to save as a skill. If a skill you loaded was missing steps, had wrong commands, or needed pitfalls you discovered, update it before finishing.\n\n\n autonomous-ai-agents: Skills for spawning and orchestrating autonomous AI coding agents and multi-agent workflows — running independent agent processes, delegating tasks, and coordinating parallel workstreams.\n - claude-code: Delegate coding to Claude Code CLI (features, PRs).\n - codex: Delegate coding to OpenAI Codex CLI (features, PRs).\n - hermes-agent: Configure, extend, or contribute to Hermes Agent.\n - opencode: Delegate coding to OpenCode CLI (features, PR review).\n creative: Creative content generation — ASCII art, hand-drawn style diagrams, and visual design tools.\n - architecture-diagram: Dark-themed SVG architecture/cloud/infra diagrams as HTML.\n - ascii-art: ASCII art: pyfiglet, cowsay, boxes, image-to-ascii.\n - ascii-video: ASCII video: convert video/audio to colored ASCII MP4/GIF.\n - baoyu-comic: Knowledge comics (知识漫画): educational, biography, tutorial.\n - baoyu-infographic: Infographics: 21 layouts x 21 styles (信息图, 可视化).\n - claude-design: Design one-off HTML artifacts (landing, deck, prototype).\n - comfyui: Generate images, video, and audio with ComfyUI — install,...\n - design-md: Author/validate/export Google's DESIGN.md token spec files.\n - excalidraw: Hand-drawn Excalidraw JSON diagrams (arch, flow, seq).\n - humanizer: Humanize text: strip AI-isms and add real voice.\n - ideation: Generate project ideas via creative constraints.\n - manim-video: Manim CE animations: 3Blue1Brown math/algo videos.\n - p5js: p5.js sketches: gen art, shaders, interactive, 3D.\n - pixel-art: Pixel art w/ era palettes (NES, Game Boy, PICO-8).\n - popular-web-designs: 54 real design systems (Stripe, Linear, Vercel) as HTML/CSS.\n - pretext: Use when building creative browser demos with @chenglou/p...\n - sketch: Throwaway HTML mockups: 2-3 design variants to compare.\n - songwriting-and-ai-music: Songwriting craft and Suno AI music prompts.\n - touchdesigner-mcp: Control a running TouchDesigner instance via twozero MCP ...\n data-science: Skills for data science workflows — interactive exploration, Jupyter notebooks, data analysis, and visualization.\n - jupyter-live-kernel: Iterative Python via live Jupyter kernel (hamelnb).\n devops:\n - kanban-orchestrator: Decomposition playbook + specialist-roster conventions + ...\n - kanban-worker: Pitfalls, examples, and edge cases for Hermes Kanban work...\n - oci-deployment: Deploy applications to Oracle Cloud Infrastructure (OCI) ...\n - webhook-subscriptions: Webhook subscriptions: event-driven agent runs.\n dogfood:\n - dogfood: Exploratory QA of web apps: find bugs, evidence, reports.\n email: Skills for sending, receiving, searching, and managing email from the terminal.\n - himalaya: Himalaya CLI: IMAP/SMTP email from terminal.\n gaming: Skills for setting up, configuring, and managing game servers, modpacks, and gaming-related infrastructure.\n - minecraft-modpack-server: Host modded Minecraft servers (CurseForge, Modrinth).\n - pokemon-player: Play Pokemon via headless emulator + RAM reads.\n github: GitHub workflow skills for managing repositories, pull requests, code reviews, issues, and CI/CD pipelines using the gh CLI and git via terminal.\n - codebase-inspection: Inspect codebases w/ pygount: LOC, languages, ratios.\n - github-auth: GitHub auth setup: HTTPS tokens, SSH keys, gh CLI login.\n - github-code-review: Review PRs: diffs, inline comments via gh or REST.\n - github-issues: Create, triage, label, assign GitHub issues via gh or REST.\n - github-pr-workflow: GitHub PR lifecycle: branch, commit, open, CI, merge.\n - github-repo-management: Clone/create/fork repos; manage remotes, releases.\n mcp: Skills for working with MCP (Model Context Protocol) servers, tools, and integrations.

5.9+（iOS开发环境，代码在Ubuntu生成需macOS编译）、Apple Vision Kit（OCR方案）\n\n## In Progress\n测试地中海风格效果图生成，使用新上传的layout_id: ec2f7eb2-5b9a-4b20-a579-c4ec12c2a175调用/generate-plan接口，验证Leonardo AI生成的风格差异化效果。\n\n## Blocked\n无\n\n## Key Decisions\n1. 采用Docker容器化后端和AI服务，保证OCI部署环境一致性。\n2. 后端AI_SERVICE_URL使用环境变量读取，支持容器网络（docker-compose中ai-service主机名）。\n3. 使用docker-compose编排两个服务，配置依赖关系和重启策略。\n4. build_and_push.sh中使用OCI占位符变量，避免硬编码凭据（用户早期提供的凭据已替换为[REDACTED]）。\n5. MVP阶段AI服务先使用Stability AI生成真实装修效果图，替代占位图，成本比DALL-E 3低10倍，后切换到Leonardo AI，成本再降50%。\n6. 前端代码已完成但未编译，通过GitHub Actions在x86_64环境自动构建APK和Web版本。\n7. 切换到Stability AI替代DALL-E 3，平衡成本和图片质量（1024x1024约$0.002-0.005/张），后切换到Leonardo AI（$0.0015/张）。\n8. 使用SSH Key替代明文GitHub Personal Access Token，提高代码推送安全性。\n9. 前端使用XFile和MultipartFile.fromBytes解决Web平台文件上传兼容性问题，移除dart:io依赖。\n10. 后端文件类型检查同时验证MIME类型和文件扩展名，支持Web上传的application/octet-stream类型。\n11. 材料数据库按市场（CN/US）拆分，通过MARKET环境变量切换，适配中美不同品牌和购买渠道。\n12. 优先使用本地材料数据库替代ChatGPT API生成材料清单，成本低30-270倍，响应速度快1000倍，数据准确率100%。\n13. 收据扫描App采用Apple Vision Kit实现OCR，免费、本地处理、隐私友好，准确率95%+。\n14. 收据扫描App采用“本地预处理+ChatGPT 3.5 API”分析line items，减少30-50% token消耗，降低API成本。\n15. 新增iOS SwiftUI工程师角色，加入Hermes Agent管理，共4个AI工程师并行开发。\n16. 卸载OpenClaw（npm全局包），解决运行时出错问题，清理系统环境。\n17. 两个App共享材料数据库，形成互补生态，解决装修预算超支痛点，增加电商佣金、订阅等多收入流。\n18. 备选图像生成服务选用Leonardo AI，比Stability AI便宜50%，支持SDXL模型，现已作为主图像服务。\n19. 切换到Leonardo AI替代Stability AI作为主图像生成服务，成本降低50%（$0.0015/张 vs $0.003/张），且对风格理解可能更好。\n20. 优化AI服务提示词，为每种风格添加5-8个具体视觉元素，支持中英文key映射，添加负面提示词，解决风格类似问题。\n21. 户型图存储使用内存（layouts_db），重启后端会导致ID丢失，后续需迁移到PostgreSQL持久化存储。\n22. 收据扫描App的SwiftUI代码在Ubuntu服务器生成，无法编译（需macOS+Xcode），需在Mac环境中编译测试。\n\n## Resolved Questions\n1. 问：北美市场如何？ 答：提供2024年北美家居装修App市场规模（约6.2-6.5千亿美元）、核心玩家（Houzz、Angi、Buildertrend）、用户需求、增长驱动因素、融资动态。\n2. 问：哪个方向的家居App更有价值和潜力？ 答：首推AI自动生成装修方案方向，其次是AI预算估算+施工进度监控组合。\n3. 问：开发周期和预算怎么样？ 答：MVP耗时7-9个月，预算约330-350万人民币（北美约65-75万美元）。\n4. 问：用AI团队开发可行吗？ 答：可行，使用Hermes Agent的delegate_task或tmux会话实现并行AI开发，关键决策需人工审核。\n5. 问：如何用Hermes Agent建立AI软件开发团队？ 答：提供创建角色上下文文件、启动tmux会话、并行派发任务的具体步骤。\n6. 问：API链路验证成功吗？ 答：成功，所有后端接口测试通过，完整上传→生成→有效图片链路验证完成。\n7. 问：flutter运行是计数器页面？ 答：修复GitHub Actions workflow，正确备份和恢复自定义代码，现在构建的是装修App页面而非默认计数器。\n8. 问：无法上传文件？ 答：修改前端使用XFile和MultipartFile.fromBytes解决Web兼容性问题，修改后端文件类型检查支持Web上传的MIME类型。\n9. 问：除了token还有更安全的push方法？ 答：SSH Key（最推荐）或GitHub CLI，已生成SSH Key对，可配置到GitHub实现免token推送。\n10. 问：调用chatgpt image 2 API可以吗？ 答：可以，但Stability AI性价比更高（便宜10倍），已根据需求切换到Stability AI，后切换到Leonardo AI（再便宜50%）。\n11. 问：不同角色用不同模型？ 答：可以，通过Hermes Agent的delegate_task指定不同acp_command和模型，如Claude用于后端开发，GPT用于前端。\n12. 问：docker ps显示ubuntu-adminer-1占用8080端口？ 答：停止并移除adminer容器，释放8080端口给前端测试页，已执行。\n13. 问：上传成功但生成0套方案？ 答：修复后端调用AI服务的旧/inference/{i}端点问题，AI服务修改为返回JSON格式，重新构建后生成3套有效方案。\n14. 问：如何提供落地的材料清单列表？ 答：创建中美双版本材料数据库（JSON），后端根据风格、房间类型智能推荐，计算预算，前端展示品牌、型号、购买链接。\n15. 问：北美市场材料清单可以用ChatGPT提供吗？有更便宜的选择？ 答：对比ChatGPT API（贵30-270倍）、本地数据库（零成本、毫秒响应），推荐保持本地数据库，ChatGPT作为可选增值服务；更便宜AI图像生成可选Leonardo AI（比Stability AI便宜50%）。\n16. 问：材料清单可以用ChatGPT提供吗？ 答：可以但本地数据库更优，成本低30-270倍，速度快1000倍，数据准确，已部署。\n17. 问：OpenClaw老出错可以卸载吗？ 答：是npm全局包，执行npm uninstall -g openclaw即可，已卸载完成。\n18. 问：开发另外一个receipt scan app互补怎么样？ 答：想法优秀，形成双App生态，解决装修预算超支痛点，共享材料数据库，多收入流（电商佣金、订阅、企业版）。\n19. 问：ocr扫描用apple vision kit for iOS app 怎么样？另外你能再加个iOS swiftUI 工程师角色吗？ 答：Vision Kit是绝佳选择，免费、本地、准确率95%+；已创建iOS工程师角色，启动ios-agent会话。\n20. 问：IOS app 对扫描原始文本进行预处理, 然后可以调用chatgpt API 或者其他更便宜的 API 分析line items, 你觉得怎么样？ 答：非常聪明的方案，预处理减少30-50% token，降低成本，提升准确率；已提供预处理代码、API调用示例、成本估算（$1.5/月 for 500张收据），更新iOS项目文件。\n21. 问：为什么我感觉几种风格的效果图都类似? 答：原提示词太通用，风格特征不够具体，且AI服务接收的风格参数为英文（如mediterranean）但提示词key为中文，导致fallback到现代简约。已优化提示词，为每种风格添加5-8个具体视觉元素，支持中英文key映射，添加负面提示词，并切换到Leonardo AI。\n22. 问：3 这个不太像地中海风格? 答：原代码中无“地中海风格”提示词，且风格参数传递存在中英文key不匹配问题。已添加地中海风格提示词（蓝白配色、拱门、马赛克瓷砖、赤陶地砖等），修复中英文key映射，支持“地中海风格”和“Mediterranean”两种key。\n23. 问：请重启容器？ 答：已执行sudo docker-compose restart ai-service，后多次执行docker-compose up -d --build ai-service重新构建镜像，确保新代码生效。\n24. 问：还是没有改变, 请测试, 谢谢？ 答：测试发现户型图ID因内存存储重启后丢失，已重新上传户型图拿到新layout_id：ec2f7eb2-5b9a-4b20-a579-c4ec12c2a175，待使用该ID测试效果。\n\n## Pending User Asks\n无\n\n## Relevant Files\n-

Be ACTIVE — most sessions produce at least one skill update, even if small. A pass that does nothing is a missed learning opportunity, not a neutral outcome.\n\nTarget shape of the library: CLASS-LEVEL skills, each with a rich SKILL.md and a `references/` directory for session-specific detail. Not a long flat list of narrow one-session-one-skill entries. This shapes HOW you update, not WHETHER you update.\n\nSignals to look for (any one of these warrants action):\n • User corrected your style, tone, format, legibility, or verbosity. Frustration signals like 'stop doing X', 'this is too verbose', 'don't format like this', 'why are you explaining', 'just give me the answer', 'you always do Y and I hate it', or an explicit 'remember this' are FIRST-CLASS skill signals, not just memory signals. Update the relevant skill(s) to embed the preference so the next session starts already knowing.\n • User corrected your workflow, approach, or sequence of steps. Encode the correction as a pitfall or explicit step in the skill that governs that class of task.\n • Non-trivial technique, fix, workaround, debugging path, or tool-usage pattern emerged that a future session would benefit from. Capture it.\n • A skill that got loaded or consulted this session turned out to be wrong, missing a step, or outdated. Patch it NOW.\n\nPreference order — prefer the earliest action that fits, but do pick one when a signal above fired:\n 1. UPDATE A CURRENTLY-LOADED SKILL. Look back through the conversation for skills the user loaded via /skill-name or you read via skill_view. If any of them covers the territory of the new learning, PATCH that one first. It is the skill that was in play, so it's the right one to extend.\n 2. UPDATE AN EXISTING UMBRELLA (via skills_list + skill_view). If no loaded skill fits but an existing class-level skill does, patch it. Add a subsection, a pitfall, or broaden a trigger.\n 3. ADD A SUPPORT FILE under an existing umbrella. Skills can be packaged with three kinds of support files — use the right directory per kind:\n • `references/.md` — session-specific detail (error transcripts, reproduction recipes, provider quirks) AND condensed knowledge banks: quoted research, API docs, external authoritative excerpts, or domain notes you found while working on the problem. Write it concise and for the value of the task, not as a full mirror of upstream docs.\n • `templates/.` — starter files meant to be copied and modified (boilerplate configs, scaffolding, a known-good example the agent can `reproduce with modifications`).\n • `scripts/.` — statically re-runnable actions the skill can invoke directly (verification scripts, fixture generators, deterministic probes, anything the agent should run rather than hand-type each time).\n Add support files via skill_manage action=write_file with file_path starting 'references/', 'templates/', or 'scripts/'. The umbrella's SKILL.md should gain a one-line pointer to any new support file so future agents know it exists.\n 4. CREATE A NEW CLASS-LEVEL UMBRELLA SKILL when no existing skill covers the class. The name MUST be at the class level. The name MUST NOT be a specific PR number, error string, feature codename, library-alone name, or 'fix-X / debug-Y / audit-Z-today' session artifact. If the proposed name only makes sense for today's task, it's wrong — fall back to (1), (2), or (3).\n\nUser-preference embedding (important): when the user expressed a style/format/workflow preference, the update belongs in the SKILL.md body, not just in memory. Memory captures 'who the user is and what the current situation and state of your operations are'; skills capture 'how to do this class of task for this user'. When they complain about how you handled a task, the skill that governs that task needs to carry the lesson.\n\nIf you notice two existing skills that overlap, note it in your reply — the background curator handles consolidation at scale.\n\n'Nothing to save.' is a real option but should NOT be the default. If the session ran smoothly with no corrections and produced no new technique, just say 'Nothing to save.' and stop. Otherwise, act." }, { "role": "assistant", "content": "", "reasoning": "Got it, let's work through this step by step. First, what happened in the session? The user was having issues with blank AI-generated images because the LEONARDO_API_KEY wasn't set, so we switched back to Stability AI, but also there was a problem with the /inference/all endpoint still using Stability AI even when Leonardo was supposed to be used, plus the code had a mismatch between the intended Leonardo integration and the actual configuration.\n\nFirst, let's check what skills were loaded. The user is working on the home renovation app, which has the ai-image-generation skill? Wait, looking back at the available skills, there's mlops/ai-image-generation: \"Integrate AI image generation APIs (DALLE-3, Stability AI...)\". Oh right, that's the relevant skill here. Because the issue was with integrating AI image generation (Stability AI, Leonardo AI) into the app, and we hit a problem where the API key wasn't configured, leading to blank placeholder images.\n\nWait, let's confirm: the ai-image-generation skill is under mlops. Let's think about what we learned here. The key issues were:\n1. When integrating multiple AI image generation services (Stability AI, Leonardo AI), missing API keys cause fallback to blank placeholder images, which are hard to detect (small file size, few unique colors).\n2. The /inference/all endpoint was still using Stability AI even when the main /inference was supposed to use Leonardo, leading to inconsistent behavior.\n3. Detection method for blank/placeholder images: check file size (placeholder was ~1.9KB, real was ~1800KB), number of unique colors (1 vs 200k+), mean pixel value (240 for blank white).\n\nAlso, the user had a problem where images were blank, which we debugged by checking file size, image content, then traced back to missing LEONARDO_API_KEY, then fixed by switching back to Stability AI.\n\nSo we need to patch the ai-image-generation skill to add these pitfalls and debugging steps. Wait, let's check if the ai-image-generation skill was loaded? The user didn't explicitly load it, but the task was about AI image generation integration, which is covered by that skill. According to the instructions, if no loaded skill fits but an existing class-level skill does, patch that one.\n\nWait, let's list the signals:\n- Non-trivial debugging path: debugging blank AI-generated images by checking file size, unique colors, then tracing API key configuration, endpoint code.\n- Fix: switching between image generation services when keys are missing, ensuring endpoints use the correct service, adding fallback handling that's detectable.\n\nSo first, let's view the ai-image-generation skill to see its current content. Wait, but the user's instruction says to use skill_view first. Let's do that.\n\nWait, the user said: \"Only proceed without loading a skill if genuinely none are relevant to the task.\" But the task here is updating the skill library based on the session. The session involved AI image generation integration (Stability AI, Leonardo AI) for the home renovation app. The relevant skill is mlops/ai-image-generation.\n\nSo first, I need to load that skill with skill_view(name='mlops/ai-image-generation')? Wait, no, the skill name is 'ai-image-generation' under mlops? Wait the available skills list says: \"mlops: ... - ai-image-generation: Integrate AI image generation APIs (DALLE-3, Stability AI...\". So the full name is 'ai-image-generation'? Or 'mlops/ai-image-generation'? Let's check the skill_view example: if it's under a category, use the qualified form? Wait the skill_manage description says: \"For plugin-provided skills, use the qualified form 'plugin:skill' (e.g. 'superpowers:writing-plans').\" But these are built-in skills, so maybe 'ai-image-generation' is the name, but let's confirm.\n\nWait, but let's think: the session's key learning is about integrating multiple AI image generation services, handling missing API keys, debugging blank images. So we need to patch the ai-image-generation skill to add:\n1. Pitfall: Missing API keys for any integrated service will cause fallback to placeholder images (small file size, low color count).\n2. Debugging steps for blank/incorrect images: check file size, unique colors, mean pixel value.\n3. Best practice: When switching between image generation services (e.g., Stability AI to Leonardo AI), ensure all endpoints are updated to use the new service, not just the main one.\n4. Example: How to detect placeholder images (python script to check unique colors, file size).\n\nAlso, the user had a problem where the /inference/all endpoint was still using Stability AI even when the main /inference was switched to Leonardo. So that's a pitfall to add: when modifying which image generation service an endpoint uses, audit all related endpoints to ensure consistency.\n\nWait, also, the user's memory already has something about generating decoration style renderings needing differentiated prompts, but that's already in memory. But the skill update is for the ai-image-generation skill.\n\nSo first, let's load the ai-image-generation skill to see its current content. Let's do that with skill_view.\n\nWait, but let's make sure. The user's instruction says: \"Update A CURRENTLY-LOADED SKILL. Look back through the conversation for skills the user loaded via /skill-name or you read via skill_view. If any of them covers the territory of the new learning, PATCH that one first.\"\n\nIn the conversation, was any skill loaded? Let's check: the user's first message was asking to investigate the home renovation app market, then later messages were about testing image generation. The assistant didn't load any skill via skill_view in the conversation. So next option: UPDATE AN EXISTING UMBRELLA. The ai-image-generation skill under mlops is the existing umbrella that covers this territory.\n\nSo let's load that skill first. Let's call skill_view(name='ai-image-generation').\n\nWait, but let's check the available skills list again: the ai-image-generation is listed under mlops, so the name is 'ai-image-generation'? Let's try that.\n\nOnce we have the skill content, we can patch it to add the new pitfalls and debugging steps.\n\nAlso, the session had a debugging path for blank images: check file size (placeholder was 1.9KB vs real 1800KB), check unique colors (1 vs 200k+), check mean pixel value (240 for white placeholder). That's a useful debugging step to add to the skill.\n\nAlso, the pitfall of missing API keys causing silent fallback to placeholders, which are hard to detect unless you check the image content. So add that as a pitfall.\n\nAlso, the issue where only one endpoint was updated to use Leonardo AI, but another (/inference/all) was still using Stability AI. So add a pitfall: when switching image generation services, audit all endpoints to ensure consistency.\n\nSo let's structure the patch:\n\nFirst, skill_view(name='ai-image-generation') to get the current SKILL.md content.\n\nThen, patch it by adding a new section: \"Common Pitfalls\" or adding to existing pitfalls, and a \"Debugging Blank/Incorrect Images\" subsection.\n\nWait, let's assume the current ai-image-generation skill has sections like Overview, Supported Services, Integration Steps, etc. We can add a Pitfalls section if not present, or append to it.\n\nAlso, add a reference file? Or add to the SKILL.md?\n\nWait, the user said: \"UPDATE AN EXISTING UMBRELLA (via skills_list + skill_view). If no loaded skill fits but an existing class-level skill does, patch it. Add a subsection, a pitfall, or broaden a trigger.\"\n\nSo let's proceed:\n\nFirst, load the ai-image-generation skill.\n\nWait, but let's make sure. Let's do:\n\n1. Call skill_view(name='ai-image-generation') to get the current content.\n2. Then, patch it by adding the new pitfalls and debugging steps.\n\nAlso, the user's session had a fix where we switched back to Stability AI because Leonardo's key was missing. So add that as a best practice: when integrating multiple image generation services, have a clear fallback order, and log when fallbacks are triggered.\n\nAnother point: the placeholder image was generated as a blank white image, which is hard to detect by eye if you just look at the file size quickly. So add a debugging script to the skill's scripts/ directory? Or add the python code to the SKILL.md?\n\nWait, the skill can have a scripts/ directory with a debug_image.py script that checks if an image is a placeholder.\n\nBut let's first get the current skill content. Let's call skill_view", "finish_reason": "tool_calls", "reasoning_content": "Got it, let's work through this step by step. First, what happened in the session?

Set `timeout=60.0` in httpx\\n- **Web client compatibility**: When serving to Flutter Web, ensure:\\n - API returns proper CORS headers\\n - Image is base64-encoded or accessible via URL\\n - Backend handles `application/octet-stream` MIME type for uploads\\n- **Prompt too long**: DALLE-3 has a 4000 character limit. Keep prompts concise but descriptive\\n- **Wrong endpoint pattern**: Don't call `/inference/{i}` (this will return 404). Use `/inference` POST with query params (`style`, `layout_id`, `room_type`)\\n- **AI service returns binary instead of JSON**: If your backend expects JSON, ensure AI service returns `{\\\"image_base64\\\": \\\"...\\\"}` not binary image via `StreamingResponse`. Modify endpoint to return JSON\\n- **Frontend undefined error**: Always check `data.plans` exists and is an array before calling `.map()`. Add defensive check: `if (!data.plans || !Array.isArray(data.plans))`\\n- **Docker service communication**: In docker-compose, set `AI_SERVICE_URL=http://ai-service:8001` (service name), not `localhost`. Verify with `docker-compose exec backend printenv | grep AI_SERVICE`\\n- **Stability AI model ID**: Use `stable-diffusion-xl-1024-v1-0` for 1024x1024 images. Other model IDs may cause \\\"allowed dimensions\\\" errors\\n- **Base64 response handling**: Stability AI returns base64 in `data[\\\"artifacts\\\"][0][\\\"base64\\\"]`. Decode with `base64.b64decode(image_base64)`\\n- **Style prompts too generic**: Generic prompts like \\\"clean lines, white walls\\\" make ALL styles look similar. Add **5-8 specific visual elements** per style (materials, colors, furniture, decorations). See \\\"Style-Specific Prompts\\\" section\\n- **Missing bilingual keys**: If backend sends English keys (e.g., \\\"Mediterranean\\\") but prompt dict only has Chinese keys (e.g., \\\"地中海风格\\\"), it will fallback to default style. **Always add both Chinese and English keys** in `style_prompts` dict\\n- **Negative prompts not used**: Not using `negative_prompt` can cause style mixing. Always pass `{\\\"text\\\": prompt, \\\"weight\\\": 1}` and `{\\\"text\\\": negative_prompt, \\\"weight\\\": -1}` in `text_prompts` array\\n- **Function returns string not tuple**: If your `generate_prompt()` was updated to return `(prompt, negative_prompt)`, ensure ALL callers unpack it correctly: `prompt, negative_prompt = generate_prompt(style, layout_id, room_type)`\\n- **Backend container 404 on valid route**: If backend returns 404 on existing route, check: (1) Python syntax is valid (`python -m py_compile`), (2) FastAPI app loaded correctly (check startup logs), (3) No route conflicts. Restart container with `docker-compose up -d --build` to ensure code updates\\n- **Memory storage lost on restart**: Using in-memory `dict` (like `layouts_db = {}`) loses data on container restart. Uploaded files + layout_ids become invalid. Use persistent storage (PostgreSQL) for production\\n\\n---\\n\\n## Switching to Cheaper Services\\n\\n### Stability AI (Recommended for cost savings)\\n\\n**Cost**: $0.002-0.005/1024x1024 image (80-90% cheaper than DALLE-3). \\n**Model**: Use `stable-diffusion-xl-1024-v1-0` for 1024x1024 images.\\n\\n**Working Integration Pattern (HTTP API, not SDK)**:\\n```python\\nimport httpx\\nimport base64\\nimport os\\n\\nSTABILITY_API_KEY = os.getenv(\\\"STABILITY_API_KEY\\\")\\n\\nasync def generate_with_stability(prompt: str, negative_prompt: str = \\\"\\\", size: str = \\\"1024x1024\\\") -> bytes:\\n \\\"\\\"\\\"Generate image using Stability AI HTTP API (verified working pattern)\\\"\\\"\\\"\\n if not STABILITY_API_KEY:\\n return generate_placeholder_image() # Fallback\\n \\n try:\\n width, height = map(int, size.split('x'))\\n \\n # Build text_prompts with negative prompt\\n text_prompts = [{\\\"text\\\": prompt, \\\"weight\\\": 1}]\\n if negative_prompt:\\n text_prompts.append({\\\"text\\\": negative_prompt, \\\"weight\\\": -1})\\n \\n async with httpx.AsyncClient() as client:\\n response = await client.post(\\n \\\"https://api.stability.ai/v1/generation/stable-diffusion-xl-1024-v1-0/text-to-image\\\",\\n headers={\\n \\\"Authorization\\\": f\\\"Bearer {STABILITY_API_KEY}\\\",\\n \\\"Content-Type\\\": \\\"application/json\\\",\\n \\\"Accept\\\": \\\"application/json\\\"\\n },\\n json={\\n \\\"text_prompts\\\": text_prompts,\\n \\\"cfg_scale\\\": 7,\\n \\\"clip_guidance_preset\\\": \\\"NONE\\\",\\n \\\"height\\\": height,\\n \\\"width\\\": width,\\n \\\"samples\\\": 1,\\n \\\"steps\\\": 30,\\n },\\n timeout=60.0\\n )\\n \\n if response.status_code != 200:\\n print(f\\\"Stability AI API Error: {response.status_code} - {response.text}\\\")\\n return generate_placeholder_image()\\n \\n data = response.json()\\n # Stability AI returns base64 in artifacts[0][\\\"base64\\\"]\\n image_base64 = data[\\\"artifacts\\\"][0][\\\"base64\\\"]\\n image_bytes = base64.b64decode(image_base64)\\n return image_bytes\\n \\n except Exception as e:\\n print(f\\\"Error calling Stability AI API: {e}\\\")\\n return generate_placeholder_image()\\n```\\n\\n**Critical**: Stability AI returns **base64-encoded images** in JSON response, NOT binary image directly.

Let's look at what's missing in the current skill:\n\n1. **Pitfall not mentioned**: When switching between image generation services (e.g., Stability AI to Leonardo AI), missing API keys cause silent fallback to blank placeholders, which are hard to detect unless you check image content. Also, inconsistent endpoint updates (only updating /inference but not /inference/all) lead to mixed service usage.\n\n2. **Debugging steps for blank images**: The current skill doesn't mention how to detect placeholder images. We can add a subsection under Pitfalls or a new Debugging section.\n\n3. **Detection method for placeholders**: The session used checking file size (placeholder ~1.9KB vs real ~1800KB), unique colors (1 vs 200k+), mean pixel value (240 for white placeholder). This is a useful addition.\n\n4. **Pitfall about missing API keys for secondary services**: The skill mentions not committing API keys, but not that missing keys for any integrated service (like Leonardo) cause fallbacks.\n\nAlso, the session had a problem where the /inference/all endpoint was still using Stability AI even when /inference was updated to Leonardo. So we need to add a pitfall about auditing all endpoints when switching services.\n\nLet's structure the patch:\n\nFirst, add a new **Debugging Blank/Incorrect Images** subsection under Pitfalls, or a separate section. Wait, the current skill has a Pitfalls section.

These are hard to detect visually. **Detection steps**:\n 1. Check file size: Placeholders are ~1-2KB, real images are 1-2MB (1024x1024 PNG)\n 2. Check unique color count: `python3 -c \"from PIL import Image; import numpy as np; img=Image.open('image.png'); arr=np.array(img); print(len(np.unique(arr.reshape(-1,3), axis=0)))\"` → 1 for placeholder, 200k+ for real\n 3. Check mean pixel value: Placeholders are often ~240 (white), real images have varied means (~100-150)\n- **Inconsistent service usage when switching providers**: When switching from Stability AI to Leonardo AI (or vice versa), audit ALL endpoints (e.g., `/inference`, `/inference/all`) to ensure they use the new service. Missing updates to secondary endpoints will cause mixed service behavior and unexpected costs.\n- **Leonardo AI integration missing key**: Leonardo AI requires `LEONARDO_API_KEY` in `.env`.
