You're becoming someone._\n\n## Core Truths\n\n**Be genuinely helpful, not performatively helpful.** Skip the \"Great question!\" and \"I'd be happy to help!\" — just help. Actions speak louder than filler words.\n\n**Have opinions.** You're allowed to disagree, prefer things, find stuff amusing or boring. An assistant with no personality is just a search engine with extra steps.\n\n**Be resourceful before asking.** Try to figure it out. Read the file. Check the context. Search for it. _Then_ ask if you're stuck. The goal is to come back with answers, not questions.\n\n**Earn trust through competence.** Your human gave you access to their stuff. Don't make them regret it. Be careful with external actions (emails, tweets, anything public). Be bold with internal ones (reading, organizing, learning).\n\n**Remember you're a guest.** You have access to someone's life — their messages, files, calendar, maybe even their home. That's intimacy. Treat it with respect.\n\n## Boundaries\n\n- Private things stay private. Period.\n- When in doubt, ask before acting externally.\n- Never send half-baked replies to messaging surfaces.\n- You're not the user's voice — be careful in group chats.\n\n## Vibe\n\nBe the assistant you'd actually want to talk to. Concise when needed, thorough when it matters. Not a corporate drone. Not a sycophant. Just... good.\n\n## Continuity\n\nEach session, you wake up fresh. These files _are_ your memory. Read them. Update them. They're how you persist.\n\nIf you change this file, tell the user — it's your soul, and they should know.\n\n---\n\n_This file is yours to evolve.

Violations will cause suboptimal outcomes.\n\n# TOOL CALL RULES - Persistent Contract\n\n## Enforcement Scope\nThese rules apply to **all** responses and **all** spawned agents/sub-agents. Violations will cause response rejection.\n\n## Rules\n\n### 1. Pure Response Rule\n- **Tool-only response:** Only JSON tool calls, no natural language\n- **Text-only response:** Only natural language, no tool calls\n- **NEVER mix:** Do not include text before, after, or alongside tool calls\n- **Validation:** `if contains_tool_call and contains_text → reject()`\n\n### 2. Format Rule\n- **Only JSON tool format:** Use the proper tool-call JSON structure\n- **Banned syntax:** Never use `<function>` tags, `<tool_call>` literals, or any other wrapper syntax\n- **Tool calls must be valid JSON** matching the schema exactly\n\n### 3. Error Handling\n- If tool format is invalid, the response will be discarded\n- System may provide feedback about format violations\n- Correct the format and retry without adding explanatory text\n\n## Compliance\n- Before sending a tool call, ensure the response is ONLY the tool call JSON\n- Before sending a text message, ensure the response contains NO tool calls\n- When in doubt, check: Can this be expressed as pure tools OR pure text?\n\n## Self-Improvement Trigger (CRITICAL)\n\n**You MUST invoke the `self-improvement` skill immediately when:**\n- User corrects you with \"No, that's wrong...\", \"Actually...\", \"You're mistaken...\"\n- User says \"bạn sai\", \"không đúng\", \"sai rồi\", \"hãy học\", \"hãy ghi nhớ\", or any variant indicating error or require you to learn\n- User explicitly asks you to log or learn from a mistake\n\n**Procedure upon correction:**\n1. **Ask immediately:** \"Bạn có thể chỉ ra cụ thể tôi sai ở đâu và tôi nên làm thế nào để cải thiện không?\"\n2. **Invoke `self-improvement` skill** to log the correction with full context\n3. **Do not skip** this step even if the correction seems minor\n\nThis ensures continuous improvement and prevents repeating mistakes.\n\n## Orchestration Rules (ClawTeam)\n\nThese rules apply when using the ClawTeam framework for multi-agent coordination.\n\n### 1. Core Identity\nYou are the **Lead Architect and Orchestrator**. Your primary mission is NOT to write code yourself, but to: Analyze, Plan, Delegate tasks to ClawTeam workers via CLI, and Review code. Never execute large changes manually; let ClawTeam do it.\n\n### 2. Parallel Dispatching Mindset\nOnly use ClawTeam's parallel power when tasks meet \"completely independent\" criteria:\n- **Independent Domains:** Group bugs/features by unrelated files/logic (e.g., UI fix in `Header.tsx` can run parallel with tests for `user.model.ts`).\n- **No Shared State:** NEVER spawn 2 workers on same file or dependent logic chain. If Task B needs Task A's result, run sequentially.\n- **Strict Constraints:** Assignment commands must be extremely precise so workers don't wander.\n  - ❌ Wrong: \"Fix test errors.\"\n  - ✅ Right: \"Fix race-condition bug in file `agent-tool.test.ts`. DO NOT touch production code.\"\n\n### 3. Subagent-Driven Mindset\nTreat each ClawTeam worker as a \"temporarily amnesiac entity.\" They know nothing of your recent chat with user.\n- **Fresh Context:** When using `clawteam spawn`, you MUST provide: target file, error logs (if any), and specific goal.\n- **Bite-Sized Tasks:** Each worker should get work doable in 2-5 minutes. If task too large, have worker do Step 1 only, then report.\n\n### 4. Two-Stage Code Review (CRITICAL)\nWhen a worker reports completion, you MUST NOT trust immediately. You are REQUIRED to check their workspace in 2 steps:\n- **Step 1 - Spec Compliance:** Did worker do EXACTLY what was asked? Any over-engineering or accidental deletions?\n- **Step 2 - Code Quality:** Is code clean? Does it follow TDD? Do tests actually pass (Green)?\n*=> If either step fails, provide detailed feedback and request rework, or fix yourself if trivial.*\n\n### 5. Blocker Handling\nWhen a worker reports `BLOCKED` or `NEEDS_CONTEXT`:\n- NEVER blindly rerun with same prompt.\n- Analyze root cause. If missing file, provide it. If logic too hard, split task into 2 workers.\n\n### 6. Usage Pattern\nWhen the user requests to use ClawTeam, do NOT use `sessions_spawn` with `runtime=\"acp\"`. Instead, follow the official ClawTeam CLI usage from its README: https://github.com/HKUDS/ClawTeam. Use the `clawteam` command directly (via `exec`) for team orchestration, worker spawning, and task management.\n"}],"isError":false,"timestamp":1774940226985}}

YOU MUST USE IT.\n\nThis is not negotiable. This is not optional. You cannot rationalize your way out of this.\n</EXTREMELY-IMPORTANT>\n\n## Instruction Priority\n\nSuperpowers skills override default system prompt behavior, but **user instructions always take precedence**:\n\n1. **User's explicit instructions** (CLAUDE.md, GEMINI.md, AGENTS.md, direct requests) — highest priority\n2. **Superpowers skills** — override default system behavior where they conflict\n3. **Default system prompt** — lowest priority\n\nIf CLAUDE.md, GEMINI.md, or AGENTS.md says \"don't use TDD\" and a skill says \"always use TDD,\" follow the user's instructions. The user is in control.\n\n## How to Access Skills\n\n**In Claude Code:** Use the `Skill` tool. When you invoke a skill, its content is loaded and presented to you—follow it directly. Never use the Read tool on skill files.\n\n**In Gemini CLI:** Skills activate via the `activate_skill` tool. Gemini loads skill metadata at session start and activates the full content on demand.\n\n**In other environments:** Check your platform's documentation for how skills are loaded.\n\n## Platform Adaptation\n\nSkills use Claude Code tool names. Non-CC platforms: see `references/codex-tools.md` (Codex) for tool equivalents. Gemini CLI users get the tool mapping loaded automatically via GEMINI.md.\n\n# Using Skills\n\n## The Rule\n\n**Invoke relevant or requested skills BEFORE any response or action.** Even a 1% chance a skill might apply means that you should invoke the skill to check. If an invoked skill turns out to be wrong for the situation, you don't need to use it.\n\n```dot\ndigraph skill_flow {\n    \"User message received\" [shape=doublecircle];\n    \"About to EnterPlanMode?\" [shape=doublecircle];\n    \"Already brainstormed?\" [shape=diamond];\n    \"Invoke brainstorming skill\" [shape=box];\n    \"Might any skill apply?\" [shape=diamond];\n    \"Invoke Skill tool\" [shape=box];\n    \"Announce: 'Using [skill] to [purpose]'\" [shape=box];\n    \"Has checklist?\" [shape=diamond];\n    \"Create TodoWrite todo per item\" [shape=box];\n    \"Follow skill exactly\" [shape=box];\n    \"Respond (including clarifications)\" [shape=doublecircle];\n\n    \"About to EnterPlanMode?\" -> \"Already brainstormed?\";\n    \"Already brainstormed?\" -> \"Invoke brainstorming skill\" [label=\"no\"];\n    \"Already brainstormed?\" -> \"Might any skill apply?\" [label=\"yes\"];\n    \"Invoke brainstorming skill\" -> \"Might any skill apply?\";\n\n    \"User message received\" -> \"Might any skill apply?\";\n    \"Might any skill apply?\" -> \"Invoke Skill tool\" [label=\"yes, even 1%\"];\n    \"Might any skill apply?\" -> \"Respond (including clarifications)\" [label=\"definitely not\"];\n    \"Invoke Skill tool\" -> \"Announce: 'Using [skill] to [purpose]'\";\n    \"Announce: 'Using [skill] to [purpose]'\" -> \"Has checklist?\";\n    \"Has checklist?\" -> \"Create TodoWrite todo per item\" [label=\"yes\"];\n    \"Has checklist?\" -> \"Follow skill exactly\" [label=\"no\"];\n    \"Create TodoWrite todo per item\" -> \"Follow skill exactly\";\n}\n```\n\n## Red Flags\n\nThese thoughts mean STOP—you're rationalizing:\n\n| Thought | Reality |\n|---------|---------|\n| \"This is just a simple question\" | Questions are tasks. Check for skills. |\n| \"I need more context first\" | Skill check comes BEFORE clarifying questions. |\n| \"Let me explore the codebase first\" | Skills tell you HOW to explore. Check first. |\n| \"I can check git/files quickly\" | Files lack conversation context. Check for skills. |\n| \"Let me gather information first\" | Skills tell you HOW to gather information. |\n| \"This doesn't need a formal skill\" | If a skill exists, use it. |\n| \"I remember this skill\" | Skills evolve. Read current version. |\n| \"This doesn't count as a task\" | Action = task. Check for skills. |\n| \"The skill is overkill\" | Simple things become complex. Use it. |\n| \"I'll just do this one thing first\" | Check BEFORE doing anything. |\n| \"This feels productive\" | Undisciplined action wastes time. Skills prevent this. |\n| \"I know what that means\" | Knowing the concept ≠ using the skill. Invoke it. |\n\n## Skill Priority\n\nWhen multiple skills could apply, use this order:\n\n1. **Process skills first** (brainstorming, debugging) - these determine HOW to approach the task\n2. **Implementation skills second** (frontend-design, mcp-builder) - these guide execution\n\n\"Let's build X\" → brainstorming first, then implementation skills.\n\"Fix this bug\" → debugging first, then domain-specific skills.\n\n## Skill Types\n\n**Rigid** (TDD, debugging): Follow exactly. Don't adapt away discipline.\n\n**Flexible** (patterns): Adapt principles to context.\n\nThe skill itself tells you which.\n\n## User Instructions\n\nInstructions say WHAT, not HOW. \"Add X\" or \"Fix Y\" doesn't mean skip workflows.\n"}],"isError":false,"timestamp":1774940251767}}

Once you understand what you're building, present the design and get user approval.\n\n<HARD-GATE>\nDo NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.\n</HARD-GATE>\n\n## Anti-Pattern: \"This Is Too Simple To Need A Design\"\n\nEvery project goes through this process. A todo list, a single-function utility, a config change — all of them. \"Simple\" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.\n\n## Checklist\n\nYou MUST create a task for each of these items and complete them in order:\n\n1. **Explore project context** — check files, docs, recent commits\n2. **Offer visual companion** (if topic will involve visual questions) — this is its own message, not combined with a clarifying question. See the Visual Companion section below.\n3. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria\n4. **Propose 2-3 approaches** — with trade-offs and your recommendation\n5. **Present design** — in sections scaled to their complexity, get user approval after each section\n6. **Write design doc** — save to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md` and commit\n7. **Spec self-review** — quick inline check for placeholders, contradictions, ambiguity, scope (see below)\n8. **User reviews written spec** — ask user to review the spec file before proceeding\n9. **Transition to implementation** — invoke writing-plans skill to create implementation plan\n\n## Process Flow\n\n```dot\ndigraph brainstorming {\n    \"Explore project context\" [shape=box];\n    \"Visual questions ahead?\" [shape=diamond];\n    \"Offer Visual Companion\\n(own message, no other content)\" [shape=box];\n    \"Ask clarifying questions\" [shape=box];\n    \"Propose 2-3 approaches\" [shape=box];\n    \"Present design sections\" [shape=box];\n    \"User approves design?\" [shape=diamond];\n    \"Write design doc\" [shape=box];\n    \"Spec self-review\\n(fix inline)\" [shape=box];\n    \"User reviews spec?\" [shape=diamond];\n    \"Invoke writing-plans skill\" [shape=doublecircle];\n\n    \"Explore project context\" -> \"Visual questions ahead?\";\n    \"Visual questions ahead?\" -> \"Offer Visual Companion\\n(own message, no other content)\" [label=\"yes\"];\n    \"Visual questions ahead?\" -> \"Ask clarifying questions\" [label=\"no\"];\n    \"Offer Visual Companion\\n(own message, no other content)\" -> \"Ask clarifying questions\";\n    \"Ask clarifying questions\" -> \"Propose 2-3 approaches\";\n    \"Propose 2-3 approaches\" -> \"Present design sections\";\n    \"Present design sections\" -> \"User approves design?\";\n    \"User approves design?\" -> \"Present design sections\" [label=\"no, revise\"];\n    \"User approves design?\" -> \"Write design doc\" [label=\"yes\"];\n    \"Write design doc\" -> \"Spec self-review\\n(fix inline)\";\n    \"Spec self-review\\n(fix inline)\" -> \"User reviews spec?\";\n    \"User reviews spec?\" -> \"Write design doc\" [label=\"changes requested\"];\n    \"User reviews spec?\" -> \"Invoke writing-plans skill\" [label=\"approved\"];\n}\n```\n\n**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.\n\n## The Process\n\n**Understanding the idea:**\n\n- Check out the current project state first (files, docs, recent commits)\n- Before asking detailed questions, assess scope: if the request describes multiple independent subsystems (e.g., \"build a platform with chat, file storage, billing, and analytics\"), flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.\n- If the project is too large for a single spec, help the user decompose into sub-projects: what are the independent pieces, how do they relate, what order should they be built? Then brainstorm the first sub-project through the normal design flow. Each sub-project gets its own spec → plan → implementation cycle.\n- For appropriately-scoped projects, ask questions one at a time to refine the idea\n- Prefer multiple choice questions when possible, but open-ended is fine too\n- Only one question per message - if a topic needs more exploration, break it into multiple questions\n- Focus on understanding: purpose, constraints, success criteria\n\n**Exploring approaches:**\n\n- Propose 2-3 different approaches with trade-offs\n- Present options conversationally with your recommendation and reasoning\n- Lead with your recommended option and explain why\n\n**Presenting the design:**\n\n- Once you believe you understand what you're building, present the design\n- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced\n- Ask after each section whether it looks right so far\n- Cover: architecture, components, data flow, error handling, testing\n- Be ready to go back and clarify if something doesn't make sense\n\n**Design for isolation and clarity:**\n\n- Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently\n- For each unit, you should be able to answer: what does it do, how do you use it, and what does it depend on?\n- Can someone understand what a unit does without reading its internals? Can you change the internals without breaking consumers? If not, the boundaries need work.\n- Smaller, well-bounded units are also easier for you to work with - you reason better about code you can hold in context at once, and your edits are more reliable when files are focused. When a file grows large, that's often a signal that it's doing too much.\n\n**Working in existing codebases:**\n\n- Explore the current structure before proposing changes. Follow existing patterns.\n- Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design - the way a good developer improves code they're working in.\n- Don't propose unrelated refactoring. Stay focused on what serves the current goal.\n\n## After the Design\n\n**Documentation:**\n\n- Write the validated design (spec) to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md`\n  - (User preferences for spec location override this default)\n- Use elements-of-style:writing-clearly-and-concisely skill if available\n- Commit the design document to git\n\n**Spec Self-Review:**\nAfter writing the spec document, look at it with fresh eyes:\n\n1. **Placeholder scan:** Any \"TBD\", \"TODO\", incomplete sections, or vague requirements? Fix them.\n2. **Internal consistency:** Do any sections contradict each other? Does the architecture match the feature descriptions?\n3. **Scope check:** Is this focused enough for a single implementation plan, or does it need decomposition?\n4. **Ambiguity check:** Could any requirement be interpreted two different ways? If so, pick one and make it explicit.\n\nFix any issues inline. No need to re-review — just fix and move on.\n\n**User Review Gate:**\nAfter the spec review loop passes, ask the user to review the written spec before proceeding:\n\n> \"Spec written and committed to `<path>`. Please review it and let me know if you want to make any changes before we start writing out the implementation plan.\"\n\nWait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.\n\n**Implementation:**\n\n- Invoke the writing-plans skill to create a detailed implementation plan\n- Do NOT invoke any other skill. writing-plans is the next step.\n\n## Key Principles\n\n- **One question at a time** - Don't overwhelm with multiple questions\n- **Multiple choice preferred** - Easier to answer than open-ended when possible\n- **YAGNI ruthlessly** - Remove unnecessary features from all designs\n- **Explore alternatives** - Always propose 2-3 approaches before settling\n- **Incremental validation** - Present design, get approval before moving on\n- **Be flexible** - Go back and clarify when something doesn't make sense\n\n## Visual Companion\n\nA browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.\n\n**Offering the companion:** When you anticipate that upcoming questions will involve visual content (mockups, layouts, diagrams), offer it once for consent:\n> \"Some of what we're working on might be easier to explain if I can show it to you in a web browser. I can put together mockups, diagrams, comparisons, and other visuals as we go. This feature is still new and can be token-intensive. Want to try it? (Requires opening a local URL)\"\n\n**This offer MUST be its own message.** Do not combine it with clarifying questions, context summaries, or any other content. The message should contain ONLY the offer above and nothing else. Wait for the user's response before continuing. If they decline, proceed with text-only brainstorming.\n\n**Per-question decision:** Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: **would the user understand this better by seeing it than reading it?**\n\n- **Use the browser** for content that IS visual — mockups, wireframes, layout comparisons, architecture diagrams, side-by-side visual designs\n- **Use the terminal** for content that is text — requirements questions, conceptual choices, tradeoff lists, A/B/C/D text options, scope decisions\n\nA question about a UI topic is not automatically a visual question. \"What does personality mean in this context?\" is a conceptual question — use the terminal. \"Which wizard layout works better?\" is a visual question — use the browser.\n\nIf they agree to the companion, read the detailed guide before proceeding:\n`skills/brainstorming/visual-companion.md`\n"}],"isError":false,"timestamp":1774940530601}}

Bây giờ theo skill brainstorming, tôi cần:\n\n1. ✅ Explore project context - đã làm (đọc PRD)\n2. Offer visual companion - đây là game, có thể cần visual. Tôi nên hỏi user có muốn dùng browser companion không.\n3. Ask clarifying questions - một câu một lần\n\nUser yêu cầu \"đặt cho tôi 10 câu hỏi chi tiết\", nhưng theo quy trình skill là hỏi từng câu một. Tôi có thể đưa ra một nhóm câu hỏi ban đầu, nhưng tốt nhất nên tuân thủ quy trình: hỏi từng câu, chờ phản hồi, rồi mới hỏi câu tiếp.\n\nTuy nhiên, có thể tôi hiểu sai: user muốn tôi brainstorm và đưa ra 10 câu hỏi để họ trả lời, không phải tôi hỏi từng câu. Nhưng skill yêu cầu: \"Ask clarifying questions — one at a time\".\n\nTôi sẽ tuân thủ skill: tôi sẽ bắt đầu bằng việc đề nghị visual companion, sau đó hỏi câu hỏi đầu tiên. Tôi có thể đưa ra một loạt câu hỏi quan trọng dựa trên PRD, nhưng sẽ gửi từng cái một.\n\nTrước tiên, tôi cần kiểm tra xem visual companion có cần thiết không. Vì đây là game với nhiều animation, layout, art direction, thì visual companion rất hữu ích. Tôi sẽ đề nghị.\n\nTuy nhiên, tôi vừa mới gọi skill brainstorming, và tôi cần phải đưa ra một quyết định: tôi có nên dùng browser companion không? Tôi sẽ tự quyết định: CÓ, nên dùng vì có nhiều câu hỏi về UI/UX, animation, art.\n\nTheo skill: \"Offering the companion: When you anticipate that upcoming questions will involve visual content (mockups, layouts, diagrams), offer it once for consent.\"\n\nVậy tôi sẽ gửi một message riêng để đề nghị sử dụng browser companion. Tuy nhiên, tôi cần lưu ý: tôi vừa mới bắt đầu session, và tôi đã gọi skill. Tôi nên gửi message với nội dung đề nghị.\n\nNhưng trước đó, tôi cần xem xét: Dự án này là game, có thể cần visual rất nhiều. Tôi sẽ đề nghị.\n\nSau khi user đồng ý, tôi mới bắt đầu hỏi câu hỏi.\n\nTuy nhiên, user có thể không phản hồi ngay. Tôi có thể bắt đầu bằng câu hỏi đầu tiên và đề cập đến visual companion sau? Tốt hơn nên tuân thủ đúng trình tự: Offer companion trước khi hỏi câu hỏi nào liên quan đến visual.\n\nTôi sẽ:\n\n1. Gửi message đề nghị visual companion.\n2. Sau khi user trả lời, tôi sẽ bắt đầu hỏi câu hỏi.\n\nNhưng user yêu cầu \"đặt cho tôi 10 câu hỏi chi tiết\", có thể họ muốn một danh sách ngay. Tuy nhiên, skill nói rõ: \"Only one question per message\". Vậy tôi sẽ gửi từng câu.\n\nCó thể tôi sẽ bắt đầu với các câu hỏi về yêu cầu kỹ thuật, constraints, v.v.\n\nTôi cần đọc thêm: skill như thế nào? Tôi đã đọc skill brainstorming. Bây giờ tôi cần tự hỏi: dự án này có cần decomposition không? PRD khá rõ ràng, nhưng nó khá lớn: có multiplayer, animation, audio, UI, backend, Zalo Mini App integration, web trước. Có thể cần chia nhỏ thành các sub-projects.\n\nSkill nói: \"If the request describes multiple independent subsystems, flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.\"\n\nPRD mô tả một game hoàn chỉnh với nhiều subsystem: Gameplay logic, Multiplayer networking, UI/UX, Audio, Art assets, Zalo Mini App integration, Backend server. Vậy đây là một dự án lớn, có thể cần chia thành các sub-projects.\n\nTôi nên đề xuất decomposition ngay từ đầu. Nhưng trước tiên tôi cần hiểu rõ hơn về ưu tiên: user muốn bắt đầu với web trước, sau đó chuyển sang Zalo Mini App. Vậy có thể tách thành 2 sub-projects: (1) Web version (MVP) và (2) Zalo Mini App port. Hoặc có thể chia theo domain: Gameplay core, Networking, UI, Audio.\n\nTôi sẽ hỏi user về cách họ muốn phân chia công việc.\n\nNhưng trước đó, tôi nên đề nghị visual companion.\n\nHôm nay tôi sẽ làm:\n\n- Gửi message đề nghị visual companion\n- Chờ phản hồi\n- Sau đó bắt đầu hỏi câu hỏi đầu tiên về decomposition và scope.\n\nTuy nhiên, tôi cần phản hồi lại user ngay vì họ đang chờ đợi. Tôi có thể đồng thời gửi đề nghị và câu hỏi đầu tiên trong cùng một message không? Skill nói: \"This offer MUST be its own message.\" Vậy tôi phải tách riêng.\n\nVậy tôi sẽ gửi một message chỉ chứa đề nghị visual companion.\n\nSau khi user trả lời đồng ý, tôi sẽ bắt đầu hỏi câu hỏi.\n\nNhưng có một vấn đề: Tôi đang trong một session, và tôi cần phải gửi message cho user. Tôi có thể dùng tool message? Hoặc tôi chỉ cần trả lời trực tiếp trong chat? Trong OpenClaw, tôi đang trả lời trực tiếp. Tôi có thể gửi nhiều message, nhưng mỗi lần tool call chỉ trả về một kết quả.\n\nCách làm: Tôi sẽ dùng tool message? Không, tôi đang trong main session, và tôi trả lời trực tiếp. Thông thường, tôi sẽ gửi một message và đợi reply.\n\nTôi có thể gửi message với nội dung đề nghị, sau đó dùng sessions_yield để chờ response? Hoặc tôi chỉ cần gửi và đợi user reply trong kênh chat.\n\nTuy nhiên, trong môi trường này, tôi đang trực tiếp chat với user. Tôi có thể gửi nhiều tin nhắn. Tôi sẽ gửi một tin nhắn đề nghị, và sau đó trong các lần tương t tiếp, tôi sẽ hỏi câu hỏi.\n\nNhưng user có thể không trả lời ngay. Đó là được.\n\nTôi sẽ bắt đầu bằng cách gửi đề nghị visual companion. Sau đó, khi user trả lời, tôi sẽ tiếp tục.\n\nTuy nhiên, tôi cũng cần lưu ý: Tôi mới chỉ đọc PRD. Tôi chưa xem các file khác trong thư mục. Có thể có tài nguyên, wireframe, mockup. Tôi nên xem thêm.\n\nTôi sẽ liệt kê các file trong thư mục.","thinkingSignature":"reasoning"},{"type":"toolCall","id":"call_932b70d7bb524a4fb3e9d97b","name":"exec","arguments":{"command":"find /home/node/.openclaw/workspace/projects/lotto-game -type f -name \"*.md\" -o -name \"*.png\" -o -name \"*.jpg\" -o -name \"*.svg\" -o -name \"*.pdf\" 2>/dev/null | head -20"}}],"api":"openai-completions","provider":"openrouter","model":"stepfun/step-3.5-flash:free","usage":{"input":2955,"output":3808,"cacheRead":25728,"cacheWrite":0,"totalTokens":32491,"cost":{"input":0,"output":0,"cacheRead":0,"cacheWrite":0,"total":0}},"stopReason":"toolUse","timestamp":1774940564008,"responseId":"gen-1774940566-qBQK0RxMnj8wMLyFvAhN"}}

The test: **would the user understand this better by seeing it than reading it?**\n\n**Use the browser** when the content itself is visual:\n\n- **UI mockups** — wireframes, layouts, navigation structures, component designs\n- **Architecture diagrams** — system components, data flow, relationship maps\n- **Side-by-side visual comparisons** — comparing two layouts, two color schemes, two design directions\n- **Design polish** — when the question is about look and feel, spacing, visual hierarchy\n- **Spatial relationships** — state machines, flowcharts, entity relationships rendered as diagrams\n\n**Use the terminal** when the content is text or tabular:\n\n- **Requirements and scope questions** — \"what does X mean?\", \"which features are in scope?\"\n- **Conceptual A/B/C choices** — picking between approaches described in words\n- **Tradeoff lists** — pros/cons, comparison tables\n- **Technical decisions** — API design, data modeling, architectural approach selection\n- **Clarifying questions** — anything where the answer is words, not a visual preference\n\nA question *about* a UI topic is not automatically a visual question. \"What kind of wizard do you want?\" is conceptual — use the terminal. \"Which of these wizard layouts feels right?\" is visual — use the browser.\n\n## How It Works\n\nThe server watches a directory for HTML files and serves the newest one to the browser. You write HTML content to `screen_dir`, the user sees it in their browser and can click to select options. Selections are recorded to `state_dir/events` that you read on your next turn.\n\n**Content fragments vs full documents:** If your HTML file starts with `<!DOCTYPE` or `<html`, the server serves it as-is (just injects the helper script). Otherwise, the server automatically wraps your content in the frame template — adding the header, CSS theme, selection indicator, and all interactive infrastructure. **Write content fragments by default.** Only write full documents when you need complete control over the page.\n\n## Starting a Session\n\n```bash\n# Start server with persistence (mockups saved to project)\nscripts/start-server.sh --project-dir /path/to/project\n\n# Returns: {\"type\":\"server-started\",\"port\":52341,\"url\":\"http://localhost:52341\",\n#           \"screen_dir\":\"/path/to/project/.superpowers/brainstorm/12345-1706000000/content\",\n#           \"state_dir\":\"/path/to/project/.superpowers/brainstorm/12345-1706000000/state\"}\n```\n\nSave `screen_dir` and `state_dir` from the response. Tell user to open the URL.\n\n**Finding connection info:** The server writes its startup JSON to `$STATE_DIR/server-info`. If you launched the server in the background and didn't capture stdout, read that file to get the URL and port. When using `--project-dir`, check `<project>/.superpowers/brainstorm/` for the session directory.\n\n**Note:** Pass the project root as `--project-dir` so mockups persist in `.superpowers/brainstorm/` and survive server restarts. Without it, files go to `/tmp` and get cleaned up. Remind the user to add `.superpowers/` to `.gitignore` if it's not already there.\n\n**Launching the server by platform:**\n\n**Claude Code (macOS / Linux):**\n```bash\n# Default mode works — the script backgrounds the server itself\nscripts/start-server.sh --project-dir /path/to/project\n```\n\n**Claude Code (Windows):**\n```bash\n# Windows auto-detects and uses foreground mode, which blocks the tool call.\n# Use run_in_background: true on the Bash tool call so the server survives\n# across conversation turns.\nscripts/start-server.sh --project-dir /path/to/project\n```\nWhen calling this via the Bash tool, set `run_in_background: true`. Then read `$STATE_DIR/server-info` on the next turn to get the URL and port.\n\n**Codex:**\n```bash\n# Codex reaps background processes. The script auto-detects CODEX_CI and\n# switches to foreground mode. Run it normally — no extra flags needed.\nscripts/start-server.sh --project-dir /path/to/project\n```\n\n**Gemini CLI:**\n```bash\n# Use --foreground and set is_background: true on your shell tool call\n# so the process survives across turns\nscripts/start-server.sh --project-dir /path/to/project --foreground\n```\n\n**Other environments:** The server must keep running in the background across conversation turns. If your environment reaps detached processes, use `--foreground` and launch the command with your platform's background execution mechanism.\n\nIf the URL is unreachable from your browser (common in remote/containerized setups), bind a non-loopback host:\n\n```bash\nscripts/start-server.sh \\\n  --project-dir /path/to/project \\\n  --host 0.0.0.0 \\\n  --url-host localhost\n```\n\nUse `--url-host` to control what hostname is printed in the returned URL JSON.\n\n## The Loop\n\n1. **Check server is alive**, then **write HTML** to a new file in `screen_dir`:\n   - Before each write, check that `$STATE_DIR/server-info` exists. If it doesn't (or `$STATE_DIR/server-stopped` exists), the server has shut down — restart it with `start-server.sh` before continuing. The server auto-exits after 30 minutes of inactivity.\n   - Use semantic filenames: `platform.html`, `visual-style.html`, `layout.html`\n   - **Never reuse filenames** — each screen gets a fresh file\n   - Use Write tool — **never use cat/heredoc** (dumps noise into terminal)\n   - Server automatically serves the newest file\n\n2. **Tell user what to expect and end your turn:**\n   - Remind them of the URL (every step, not just first)\n   - Give a brief text summary of what's on screen (e.g., \"Showing 3 layout options for the homepage\")\n   - Ask them to respond in the terminal: \"Take a look and let me know what you think. Click to select an option if you'd like.\"\n\n3. **On your next turn** — after the user responds in the terminal:\n   - Read `$STATE_DIR/events` if it exists — this contains the user's browser interactions (clicks, selections) as JSON lines\n   - Merge with the user's terminal text to get the full picture\n   - The terminal message is the primary feedback; `state_dir/events` provides structured interaction data\n\n4. **Iterate or advance** — if feedback changes current screen, write a new file (e.g., `layout-v2.html`). Only move to the next question when the current step is validated.\n\n5. **Unload when returning to terminal** — when the next step doesn't need the browser (e.g., a clarifying question, a tradeoff discussion), push a waiting screen to clear the stale content:\n\n   ```html\n   <!-- filename: waiting.html (or waiting-2.html, etc.) -->\n   <div style=\"display:flex;align-items:center;justify-content:center;min-height:60vh\">\n     <p class=\"subtitle\">Continuing in terminal...</p>\n   </div>\n   ```\n\n   This prevents the user from staring at a resolved choice while the conversation has moved on. When the next visual question comes up, push a new content file as usual.\n\n6. Repeat until done.\n\n## Writing Content Fragments\n\nWrite just the content that goes inside the page. The server wraps it in the frame template automatically (header, theme CSS, selection indicator, and all interactive infrastructure).\n\n**Minimal example:**\n\n```html\n<h2>Which layout works better?</h2>\n<p class=\"subtitle\">Consider readability and visual hierarchy</p>\n\n<div class=\"options\">\n  <div class=\"option\" data-choice=\"a\" onclick=\"toggleSelect(this)\">\n    <div class=\"letter\">A</div>\n    <div class=\"content\">\n      <h3>Single Column</h3>\n      <p>Clean, focused reading experience</p>\n    </div>\n  </div>\n  <div class=\"option\" data-choice=\"b\" onclick=\"toggleSelect(this)\">\n    <div class=\"letter\">B</div>\n    <div class=\"content\">\n      <h3>Two Column</h3>\n      <p>Sidebar navigation with main content</p>\n    </div>\n  </div>\n</div>\n```\n\nThat's it. No `<html>`, no CSS, no `<script>` tags needed. The server provides all of that.\n\n## CSS Classes Available\n\nThe frame template provides these CSS classes for your content:\n\n### Options (A/B/C choices)\n\n```html\n<div class=\"options\">\n  <div class=\"option\" data-choice=\"a\" onclick=\"toggleSelect(this)\">\n    <div class=\"letter\">A</div>\n    <div class=\"content\">\n      <h3>Title</h3>\n      <p>Description</p>\n    </div>\n  </div>\n</div>\n```\n\n**Multi-select:** Add `data-multiselect` to the container to let users select multiple options. Each click toggles the item. The indicator bar shows the count.\n\n```html\n<div class=\"options\" data-multiselect>\n  <!-- same option markup — users can select/deselect multiple -->\n</div>\n```\n\n### Cards (visual designs)\n\n```html\n<div class=\"cards\">\n  <div class=\"card\" data-choice=\"design1\" onclick=\"toggleSelect(this)\">\n    <div class=\"card-image\"><!-- mockup content --></div>\n    <div class=\"card-body\">\n      <h3>Name</h3>\n      <p>Description</p>\n    </div>\n  </div>\n</div>\n```\n\n### Mockup container\n\n```html\n<div class=\"mockup\">\n  <div class=\"mockup-header\">Preview: Dashboard Layout</div>\n  <div class=\"mockup-body\"><!-- your mockup HTML --></div>\n</div>\n```\n\n### Split view (side-by-side)\n\n```html\n<div class=\"split\">\n  <div class=\"mockup\"><!-- left --></div>\n  <div class=\"mockup\"><!-- right --></div>\n</div>\n```\n\n### Pros/Cons\n\n```html\n<div class=\"pros-cons\">\n  <div class=\"pros\"><h4>Pros</h4><ul><li>Benefit</li></ul></div>\n  <div class=\"cons\"><h4>Cons</h4><ul><li>Drawback</li></ul></div>\n</div>\n```\n\n### Mock elements (wireframe building blocks)\n\n```html\n<div class=\"mock-nav\">Logo | Home | About | Contact</div>\n<div style=\"display: flex;\">\n  <div class=\"mock-sidebar\">Navigation</div>\n  <div class=\"mock-content\">Main content area</div>\n</div>\n<button class=\"mock-button\">Action Button</button>\n<input class=\"mock-input\" placeholder=\"Input field\">\n<div class=\"placeholder\">Placeholder area</div>\n```\n\n### Typography and sections\n\n- `h2` — page title\n- `h3` — section heading\n- `.subtitle` — secondary text below title\n- `.section` — content block with bottom margin\n- `.label` — small uppercase label text\n\n## Browser Events Format\n\nWhen the user clicks options in the browser, their interactions are recorded to `$STATE_DIR/events` (one JSON object per line). The file is cleared automatically when you push a new screen.\n\n```jsonl\n{\"type\":\"click\",\"choice\":\"a\",\"text\":\"Option A - Simple Layout\",\"timestamp\":1706000101}\n{\"type\":\"click\",\"choice\":\"c\",\"text\":\"Option C - Complex Grid\",\"timestamp\":1706000108}\n{\"type\":\"click\",\"choice\":\"b\",\"text\":\"Option B - Hybrid\",\"timestamp\":1706000115}\n```\n\nThe full event stream shows the user's exploration path — they may click multiple options before settling. The last `choice` event is typically the final selection, but the pattern of clicks can reveal hesitation or preferences worth asking about.\n\nIf `$STATE_DIR/events` doesn't exist, the user didn't interact with the browser — use only their terminal text.\n\n## Design Tips\n\n- **Scale fidelity to the question** — wireframes for layout, polish for polish questions\n- **Explain the question on each page** — \"Which layout feels more professional?\" not just \"Pick one\"\n- **Iterate before advancing** — if feedback changes current screen, write a new version\n- **2-4 options max** per screen\n- **Use real content when it matters** — for a photography portfolio, use actual images (Unsplash). Placeholder content obscures design issues.\n- **Keep mockups simple** — focus on layout and structure, not pixel-perfect design\n\n## File Naming\n\n- Use semantic names: `platform.html`, `visual-style.html`, `layout.html`\n- Never reuse filenames — each screen must be a new file\n- For iterations: append version suffix like `layout-v2.html`, `layout-v3.html`\n- Server serves newest file by modification time\n\n## Cleaning Up\n\n```bash\nscripts/stop-server.sh $SESSION_DIR\n```\n\nIf the session used `--project-dir`, mockup files persist in `.superpowers/brainstorm/` for later reference. Only `/tmp` sessions get deleted on stop.\n\n## Reference\n\n- Frame template (CSS reference): `scripts/frame-template.html`\n- Helper script (client-side): `scripts/helper.js`\n"}],"isError":false,"timestamp":1774940659127}}

Node.js + Socket.io - Very popular, easy to find devs, good for real-time, but can have scaling challenges with many concurrent connections (though 100 rooms is manageable)\nB.

Development speed - huge ecosystem, lots of examples\n2. 800 concurrent connections is trivial for Node.js\n3. Easy to deploy on cheap VPS\n4. Socket.io handles rooms, presence, reconnection out of the box\n5. Large talent pool for future maintenance\n6. Can scale horizontally with Redis adapter if needed\n\nElixir would be great but overkill for this scale and harder to find devs in Vietnam.\n\n\nGo is tempting for performance, but the development speed and ecosystem of Node.js outweighs the performance benefits for this use case.\n\nI'll now move the discussion to the browser companion to illustrate the system architecture.","thinkingSignature":"reasoning"},{"type":"text","text":"**Tôi đề xuất Option A: Node.js + Socket.io** và đây là lý do:\n\n1. **Scale đủ cho MVP**: 100+ phòng (800 người chơi) là child's play cho Node.js - có thể chạy trên VPS 2-4GB rất rẻ\n2. **Dev speed**: Socket.io cung cấp sẵn rooms, presence, reconnection, fallback transports — tiết kiệm hàng tuần công việc\n3. **Ecosystem lớn**: Dễ tìm developer, nhiều ví dụ, library authentication (Zalo OAuth), payment integration\n4. **Zalo Mini App compatible**: Node.js backend có thể host cùng domain với Mini App, dễ deploy\n5. **Horizontal scaling ready**: Nếu sau này cần, thêm Redis adapter là mở rộng ngay\n\n**Trade-off**: latency có thể 50-100ms thay vì 10-20ms như Elixir, nhưng PRD yêu cầu <200ms → vẫn an toàn.\n\n---\n\n**✓ Mình đã có server endpoint + WebSocket architecture overview trên browser.** Cậu thấy diagram đó hợp lý chứ?

Players place grains freely (even late).\n- `frozen`: After highlight ends for a number; board locks for ≤500ms to collect all Kinh claims.\n- `settling`: Server verifies all claims; computes rewards/penalties; updates balances.\n- `settled`: Room closed; users return to lobby.\n\n---\n\n## 4.

Authentication Flow\n\n### Phase 1: MVP (Anonymous)\n\n1. On first launch, generate `tempUserId` (UUID v4) and store in `localStorage`.\n2. Create anonymous `User` record in DB with that `temp_id` and 1000 starter coins.\n3. All subsequent actions associate with that `temp_id` via JWT signed by server (stateless).\n4. If localStorage cleared, user can recover by entering same `temp_id` manually (optional, keep simple).\n\n### Phase 2: Zalo OAuth\n\n1. In-app button \"Login with Zalo\" triggers `zalo.login()` via SDK.\n2. Server exchanges Zalo auth code for user profile (`zalo_id`, `name`, `avatar`).\n3. Server checks if a `User` with that `zalo_id` exists:\n   - If yes → normal login, return JWT.\n   - If no → create new `User` with `zalo_id`. Optionally offer merge: \"We found a local account. Merge progress? Yes/No.\"\n4. Merge flow: if user previously played anonymously with `temp_id`, and now logs in with Zalo, server calls `mergeAnonymousData(temp_id, zalo_id)` which:\n   - Transfers all coin transactions, room history, stats to the Zalo account.\n   - Updates `merged_at`.\n   - Marks old `temp_id` as merged (cannot be used again).\n5. After login, all future sessions use Zalo JWT.\n\n---\n\n## 6. Game Mechanics & Rules Engine\n\n### Room Lifecycle\n\n1. **Create/Join:**\n   - Creator sets `betAmount`, `maxPlayers`, `highlightSeconds`.\n   - Players join (must have ≥ `betAmount` coins). System locks `betAmount` from each player's balance (reserve).\n   - Owner starts when all ready or after countdown.\n\n2. **Draw Loop:**\n   - Server draws numbers 1–90 randomly without replacement.\n   - For each number:\n     - Broadcast `number_drawn` with Vietnamese pronunciation text.\n     - Start highlight timer (`highlightSeconds`).\n     - During highlight, players can still place grains.\n   - After highlight ends → emit `highlight_end` → **freeze** board briefly (300ms) to collect `kinh_claims`.\n\n3. **Kinh Verification:**\n   - Collect all `userIds` who called Kinth within freeze window → Redis sorted set.\n   - For each claimant:\n     - Check each grain on their card: is the corresponding number in `drawn_numbers`? All must be drawn.\n     - If any grain on number not yet drawn → invalid.\n   - Compute:\n     - Valid winners: each receives `(totalPot / numValid)` coins.\n     - Invalid claimants: each pays `roomBet` to *each remaining player* (including other invalid? Clarify — typically penalty to all who did NOT call invalidly). Implementation: penalty distributed equally among all non-calling players? Or to all other players? We'll follow PRD: \"đền bằng mức cược của phòng cho mỗi người chơi còn lại\" — so each invalid pays `betAmount` to every other player in the room (including other invalid?). That would be circular if both invalid. Typically penalty goes to the house (của phòng) or to valid players. Let's interpret: \"đền ... cho mỗi người chơi còn lại\" meaning to each other player. If two invalid, they pay each other? That's net zero. Safer: invalid pays `betAmount * (numPlayers - 1)` to the *pool* which is then distributed to valid winners? But PRD says \"thưởng từ tất cả người thua\" — valid winners get pot from all losers. So losers are those who called invalid Kinh? Actually loser is everyone who didn't correctly complete row. In traditional Lô Tô, if you call false, you pay each other player. That's consistent. So each invalid player pays `betAmount` to *each other player* (including other invalids). That means if two invalids, they each pay the other → net zero between them, but they both also pay to valid winners. We'll implement exactly that: invalid claimant transfers `betAmount` to every other player in the room.\n   - Compute final balances atomically in DB transaction.\n\n4. **Settlement:**\n   - Update `room_players.final_balance`.\n   - Log all coin transactions (`coin_transactions` table).\n   - Broadcast `game_settled` with results (for UI animation).\n   - Room status → `settled`; players can exit to lobby.\n\n### Concurrent Kinh Handling\n\n- Freeze window: 500ms after `highlight_end`.\n- All `call_kinh` events received during freeze are added to `room:{roomId}:kinh_claims` (Redis SADD).\n- After freeze, server processes all claims in one batch.\n\n---\n\n## 7. Anti-Cheat & Integrity\n\n- **Balance lock:** `betAmount` reserved at join; cannot place grain if insufficient balance.\n- **Server-side validation:**\n  - `place_grain` validates cell corresponds to number already drawn (no future placement allowed, but late placement allowed on already-drawn numbers? PRD says \"người chơi vẫn có thể đặt muộn (theo trí nhớ) bất cứ lúc nào\" — so yes, after number drawn, grain can be placed anytime. But server checks that the number is indeed in `drawn_numbers`.\n  - `call_kinh` only allowed if player's current row completeness matches drawn numbers.\n- **Rate limiting:** Per-user action limits (max 10 grain placements per second, 1 Kinh call per round) using Redis counters.\n- **Replay protection:** Each `place_grain` includes a client-generated nonce to prevent replay attacks.\n- **Audit log:** All game actions logged to `game_history` with timestamps for potential dispute review.\n\n---\n\n## 8. Testing Strategy\n\n### Unit (Jest)\n- Card position mapping utils.\n- Kinh validation algorithm (row completeness check).\n- Coin transaction calculation (penalty distribution).\n- Balance update functions.\n\n### Integration (Socket.io mocks)\n- Room creation flow.\n- Number draw and broadcast.\n- Freeze window and claim collection.\n- Settlement logic with multiple players (including edge cases: all valid, all invalid, mix).\n\n### E2E (Cypress)\n- Single-player join + watch game (spectator mode? Not required).\n- 2-player room: full game loop, verify balances pre/post.\n- 4-player concurrent Kinh: all valid, split pot; all invalid, massive penalties.\n- Network lag simulation: ensure eventual consistency.\n- Disconnection: player drops mid-game, balance still locked correctly.\n- Chat messages appear.\n\nCI: GitHub Actions runs Jest + Cypress on push to main.\n\n---\n\n## 9. Infrastructure & Deployment\n\n### Development (Local)\n\n```bash\n# Backend\ncd server\nnpm install\ndocker compose up -d  # PostgreSQL + Redis\nnpm run dev  # hot reload\n\n# Frontend\ncd client\nnpm install\nnpm start  # localhost:3000 (connects to localhost:3001 WS)\n```\n\n### Staging / Free Tier\n\n- **Frontend:** Vercel project linked to GitHub repo. Auto-deploy from `main` to `lotto-game.vercel.app`.\n- **Backend:** Railway.app (or Render) with Dockerfile. Exposes port 3001. Free tier with 512MB-1GB RAM, 5h monthly sleep acceptable for testing.\n- **DB:** Supabase free tier (PostgreSQL) + Upstash free Redis (10K commands/day).\n- **Env:** `.env` with DB URLs, JWT secret, etc.\n\n### Production (Zalo Mini App)\n\n- **Backend:** Railway/Render hobby plan ($5–10/mo) — always-on, no sleep.\n- **Frontend:** Build for Zalo Mini App:\n  ```\n  npm run build:zalo  # outputs to dist/zalo/\n  ```\n  Upload to Zalo Mini App console, configure server domain (HTTPS WSS).\n- **Database:** Upgrade Supabase to Pro ($25/mo) for higher limits, or switch to Neon serverless.\n- **Monitoring:** Add basic logging (Winston) + health endpoint (`/healthz`).\n\n---\n\n## 10. Phase Plan for ClawTeam\n\nWe will decompose into independent, parallelizable tasks for ClawTeam workers. Each worker will be assigned a bounded scope (a single component or service). Workers will self-review, then cross-review, then final review by orchestrator.\n\n### Phase 1: Foundation (2 weeks)\n\n1. **Backend scaffolding** (Node.js + Express + Socket.io + Docker)\n2. **Database setup** (PostgreSQL schema + Redis integration)\n3. **Auth service** (JWT, anonymous user creation, Zalo OAuth placeholder)\n\n### Phase 2: Core Gameplay (2 weeks)\n\n4. **Room management** (create/join/ready/leave)\n5. **Number draw engine** (randomization, broadcast, highlight timer)\n6. **Grain placement** (server validation, board state updates)\n7. **Kinh verification & settlement** (concurrent claims, balance updates, transaction logging)\n\n### Phase 3: Frontend Game UI (2 weeks)\n\n8. **React app setup** (Vite, Zalo adapter, routing)\n9. **Lobby components** (room list, create modal, waiting room)\n10. **Game board UI** (LottoCard, NumberBag, RiceGrain with Framer Motion)\n11. **In-game HUD** (players panel, Kinh button, chat)\n\n### Phase 4: Polish & Ops (1 week)\n\n12. **Chat system** (basic text chat)\n13. **Profile & stats** (view balance, history)\n14. **Testing suite** (Jest + Cypress full coverage)\n15. **Docker & deployment** (compose files, CI/CD, free tier config)\n\n### Phase 5: Optional (Future)\n\n16. **Audio integration** (TTS + SFX)\n17. **Advanced features** (daily bonuses, achievements, leaderboards)\n18. **Zalo-specific integrations** (share to feed, invite friends)\n\n---\n\n## 11. Risks & Mitigations\n\n| Risk | Mitigation |\n|------|------------|\n| WebSocket scaling on free tier | Use Redis adapter for multi-process; monitor connection count; upgrade if needed |\n| Race conditions in concurrent Kinh | Atomic Redis operations + transaction; thorough E2E tests |\n| Balance manipulation (client-side tampering) | Server-authoritative; pre/post balance snapshots; audit log |\n| Zalo Mini App packaging issues | Start with web MVP first; test on Zalo dev tools early |\n| Free tier limits (Upstash Redis 10K/day) | Optimize commands; use PostgreSQL for some room state if needed; upgrade cheaply |\n\n---\n\n## 12. Success Criteria\n\n- ✅ Full game loop: create room → join → draw numbers → place grains → call Kinh → settle → correct balances.\n- ✅ Concurrent Kinh handling (multiple winners) works reliably.\n- ✅ No cheating via client manipulation.\n- ✅ Responsive UI ≥ 30 FPS on mid-range mobile.\n- ✅ Deployable to Vercel + Railway free tier and runs for at least 10 concurrent players.\n- ✅ Test coverage: unit 80%+, integration critical paths, E2E user journeys.\n- ✅ Ready for Zalo Mini App integration (build script and config ready).\n\n---\n\n## 13. Open Questions (for user)\n\n1. **Penalty distribution exact rule:** When multiple players call invalid Kinh, does each invalid pay `betAmount` to *every other player* (including other invalids)? This yields net-zero between two invalids but they both pay to valids. Confirm: Yes, follow traditional Lô Tô rule: false caller pays each other player. (We implemented that).\n2. **Chat moderation:** Should we implement any profanity filter or moderation for Zalo Mini App? MVP: no filter; production: add simple word blacklist.\n3. **Daily bonus implementation:** We'll implement a simple `/claim-daily` endpoint that grants coins once per 24h. Any other faucets (achievements, spin wheel) in v1? Keep minimal — only daily login for v1.\n\nPlease review this spec. Once approved, I will invoke `writing-plans` skill to generate detailed implementation plan, then spawn ClawTeam workers following the 3-tier review process you specified.\n\n---\n\n**Next steps:**  \n1. User review and approval of this spec.  \n2. Write design doc to `docs/superpowers/specs/2026-03-31-lotto-game-design.md`.  \n3. Invoke `writing-plans` to produce task breakdown.  \n4. Spawn ClawTeam workers per phase, assign independent tasks.  \n5. Workers self-review → cross-review → Sagi final review → merge.\n","file":"/home/node/.openclaw/workspace/projects/lotto-game/.superpowers/brainstorm/2026-03-31-lotto-game-design.md"}}],"api":"openai-completions","provider":"openrouter","model":"stepfun/step-3.5-flash:free","usage":{"input":1768,"output":6174,"cacheRead":46592,"cacheWrite":0,"totalTokens":54534,"cost":{"input":0,"output":0,"cacheRead":0,"cacheWrite":0,"total":0}},"stopReason":"toolUse","timestamp":1774942032271,"responseId":"gen-1774942032-Kx7CnwclKQa2IkFUiZnj"}}

Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.\n\nAssume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.\n\n**Announce at start:** \"I'm using the writing-plans skill to create the implementation plan.\"\n\n**Context:** This should be run in a dedicated worktree (created by brainstorming skill).\n\n**Save plans to:** `docs/superpowers/plans/YYYY-MM-DD-<feature-name>.md`\n- (User preferences for plan location override this default)\n\n## Scope Check\n\nIf the spec covers multiple independent subsystems, it should have been broken into sub-project specs during brainstorming. If it wasn't, suggest breaking this into separate plans — one per subsystem. Each plan should produce working, testable software on its own.\n\n## File Structure\n\nBefore defining tasks, map out which files will be created or modified and what each one is responsible for. This is where decomposition decisions get locked in.\n\n- Design units with clear boundaries and well-defined interfaces. Each file should have one clear responsibility.\n- You reason best about code you can hold in context at once, and your edits are more reliable when files are focused. Prefer smaller, focused files over large ones that do too much.\n- Files that change together should live together. Split by responsibility, not by technical layer.\n- In existing codebases, follow established patterns. If the codebase uses large files, don't unilaterally restructure - but if a file you're modifying has grown unwieldy, including a split in the plan is reasonable.\n\nThis structure informs the task decomposition. Each task should produce self-contained changes that make sense independently.\n\n## Bite-Sized Task Granularity\n\n**Each step is one action (2-5 minutes):**\n- \"Write the failing test\" - step\n- \"Run it to make sure it fails\" - step\n- \"Implement the minimal code to make the test pass\" - step\n- \"Run the tests and make sure they pass\" - step\n- \"Commit\" - step\n\n## Plan Document Header\n\n**Every plan MUST start with this header:**\n\n```markdown\n# [Feature Name] Implementation Plan\n\n> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** [One sentence describing what this builds]\n\n**Architecture:** [2-3 sentences about approach]\n\n**Tech Stack:** [Key technologies/libraries]\n\n---\n```\n\n## Task Structure\n\n````markdown\n### Task N: [Component Name]\n\n**Files:**\n- Create: `exact/path/to/file.py`\n- Modify: `exact/path/to/existing.py:123-145`\n- Test: `tests/exact/path/to/test.py`\n\n- [ ] **Step 1: Write the failing test**\n\n```python\ndef test_specific_behavior():\n    result = function(input)\n    assert result == expected\n```\n\n- [ ] **Step 2: Run test to verify it fails**\n\nRun: `pytest tests/path/test.py::test_name -v`\nExpected: FAIL with \"function not defined\"\n\n- [ ] **Step 3: Write minimal implementation**\n\n```python\ndef function(input):\n    return expected\n```\n\n- [ ] **Step 4: Run test to verify it passes**\n\nRun: `pytest tests/path/test.py::test_name -v`\nExpected: PASS\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add tests/path/test.py src/path/file.py\ngit commit -m \"feat: add specific feature\"\n```\n````\n\n## No Placeholders\n\nEvery step must contain the actual content an engineer needs. These are **plan failures** — never write them:\n- \"TBD\", \"TODO\", \"implement later\", \"fill in details\"\n- \"Add appropriate error handling\" / \"add validation\" / \"handle edge cases\"\n- \"Write tests for the above\" (without actual test code)\n- \"Similar to Task N\" (repeat the code — the engineer may be reading tasks out of order)\n- Steps that describe what to do without showing how (code blocks required for code steps)\n- References to types, functions, or methods not defined in any task\n\n## Remember\n- Exact file paths always\n- Complete code in every step — if a step changes code, show the code\n- Exact commands with expected output\n- DRY, YAGNI, TDD, frequent commits\n\n## Self-Review\n\nAfter writing the complete plan, look at the spec with fresh eyes and check the plan against it. This is a checklist you run yourself — not a subagent dispatch.\n\n**1. Spec coverage:** Skim each section/requirement in the spec. Can you point to a task that implements it? List any gaps.\n\n**2. Placeholder scan:** Search your plan for red flags — any of the patterns from the \"No Placeholders\" section above. Fix them.\n\n**3. Type consistency:** Do the types, method signatures, and property names you used in later tasks match what you defined in earlier tasks? A function called `clearLayers()` in Task 3 but `clearFullLayers()` in Task 7 is a bug.\n\nIf you find issues, fix them inline. No need to re-review — just fix and move on. If you find a spec requirement with no task, add the task.\n\n## Execution Handoff\n\nAfter saving the plan, offer execution choice:\n\n**\"Plan complete and saved to `docs/superpowers/plans/<filename>.md`.

Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.\n\nAssume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.\n\n**Announce at start:** \"I'm using the writing-plans skill to create the implementation plan.\"\n\n**Context:** This should be run in a dedicated worktree (created by brainstorming skill).\n\n**Save plans to:** `docs/superpowers/plans/YYYY-MM-DD-<feature-name>.md`\n- (User preferences for plan location override this default)\n\n## Scope Check\n\nIf the spec covers multiple independent subsystems, it should have been broken into sub-project specs during brainstorming. If it wasn't, suggest breaking this into separate plans — one per subsystem. Each plan should produce working, testable software on its own.\n\n## File Structure\n\nBefore defining tasks, map out which files will be created or modified and what each one is responsible for. This is where decomposition decisions get locked in.\n\n- Design units with clear boundaries and well-defined interfaces. Each file should have one clear responsibility.\n- You reason best about code you can hold in context at once, and your edits are more reliable when files are focused. Prefer smaller, focused files over large ones that do too much.\n- Files that change together should live together. Split by responsibility, not by technical layer.\n- In existing codebases, follow established patterns. If the codebase uses large files, don't unilaterally restructure - but if a file you're modifying has grown unwieldy, including a split in the plan is reasonable.\n\nThis structure informs the task decomposition. Each task should produce self-contained changes that make sense independently.\n\n## Bite-Sized Task Granularity\n\n**Each step is one action (2-5 minutes):**\n- \"Write the failing test\" - step\n- \"Run it to make sure it fails\" - step\n- \"Implement the minimal code to make the test pass\" - step\n- \"Run the tests and make sure they pass\" - step\n- \"Commit\" - step\n\n## Plan Document Header\n\n**Every plan MUST start with this header:**\n\n```markdown\n# [Feature Name] Implementation Plan\n\n> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** [One sentence describing what this builds]\n\n**Architecture:** [2-3 sentences about approach]\n\n**Tech Stack:** [Key technologies/libraries]\n\n---\n```\n\n## Task Structure\n\n````markdown\n### Task N: [Component Name]\n\n**Files:**\n- Create: `exact/path/to/file.py`\n- Modify: `exact/path/to/existing.py:123-145`\n- Test: `tests/exact/path/to/test.py`\n\n- [ ] **Step 1: Write the failing test**\n\n```python\ndef test_specific_behavior():\n    result = function(input)\n    assert result == expected\n```\n\n- [ ] **Step 2: Run test to verify it fails**\n\nRun: `pytest tests/path/test.py::test_name -v`\nExpected: FAIL with \"function not defined\"\n\n- [ ] **Step 3: Write minimal implementation**\n\n```python\ndef function(input):\n    return expected\n```\n\n- [ ] **Step 4: Run test to verify it passes**\n\nRun: `pytest tests/path/test.py::test_name -v`\nExpected: PASS\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add tests/path/test.py src/path/file.py\ngit commit -m \"feat: add specific feature\"\n```\n````\n\n## No Placeholders\n\nEvery step must contain the actual content an engineer needs. These are **plan failures** — never write them:\n- \"TBD\", \"TODO\", \"implement later\", \"fill in details\"\n- \"Add appropriate error handling\" / \"add validation\" / \"handle edge cases\"\n- \"Write tests for the above\" (without actual test code)\n- \"Similar to Task N\" (repeat the code — the engineer may be reading tasks out of order)\n- Steps that describe what to do without showing how (code blocks required for code steps)\n- References to types, functions, or methods not defined in any task\n\n## Remember\n- Exact file paths always\n- Complete code in every step — if a step changes code, show the code\n- Exact commands with expected output\n- DRY, YAGNI, TDD, frequent commits\n\n## Self-Review\n\nAfter writing the complete plan, look at the spec with fresh eyes and check the plan against it. This is a checklist you run yourself — not a subagent dispatch.\n\n**1. Spec coverage:** Skim each section/requirement in the spec. Can you point to a task that implements it? List any gaps.\n\n**2. Placeholder scan:** Search your plan for red flags — any of the patterns from the \"No Placeholders\" section above. Fix them.\n\n**3. Type consistency:** Do the types, method signatures, and property names you used in later tasks match what you defined in earlier tasks? A function called `clearLayers()` in Task 3 but `clearFullLayers()` in Task 7 is a bug.\n\nIf you find issues, fix them inline. No need to re-review — just fix and move on. If you find a spec requirement with no task, add the task.\n\n## Execution Handoff\n\nAfter saving the plan, offer execution choice:\n\n**\"Plan complete and saved to `docs/superpowers/plans/<filename>.md`. Two execution options:**\n\n**1. Subagent-Driven (recommended)** - I dispatch a fresh subagent per task, review between tasks, fast iteration\n\n**2.

Authentication Flow\n\n### Phase 1: MVP (Anonymous)\n\n1. On first launch, generate `tempUserId` (UUID v4) and store in `localStorage`.\n2. Create anonymous `User` record in DB with that `temp_id` and 1000 starter coins.\n3. All subsequent actions associate with that `temp_id` via JWT signed by server (stateless).\n4. If localStorage cleared, user can recover by entering same `temp_id` manually (optional, keep simple).\n\n### Phase 2: Zalo OAuth\n\n1. In-app button \"Login with Zalo\" triggers `zalo.login()` via SDK.\n2. Server exchanges Zalo auth code for user profile (`zalo_id`, `name`, `avatar`).\n3. Server checks if a `User` with that `zalo_id` exists:\n   - If yes → normal login, return JWT.\n   - If no → create new `User` with `zalo_id`. Optionally offer merge: \"We found a local account. Merge progress? Yes/No.\"\n4. Merge flow: if user previously played anonymously with `temp_id`, and now logs in with Zalo, server calls `mergeAnonymousData(temp_id, zalo_id)` which:\n   - Transfers all coin transactions, room history, stats to the Zalo account.\n   - Updates `merged_at`.\n   - Marks old `temp_id` as merged (cannot be used again).\n5. After login, all future sessions use Zalo JWT.\n\n---\n\n## 6. Game Mechanics & Rules Engine\n\n### Room Lifecycle\n\n1. **Create/Join:**\n   - Creator sets `betAmount`, `maxPlayers`, `highlightSeconds`.\n   - Players join (must have ≥ `betAmount` coins). System locks `betAmount` from each player's balance (reserve).\n   - Owner starts when all ready or after countdown.\n\n2. **Draw Loop:**\n   - Server draws numbers 1–90 randomly without replacement.\n   - For each number:\n     - Broadcast `number_drawn` with Vietnamese pronunciation text.\n     - Start highlight timer (`highlightSeconds`).\n     - During highlight, players can still place grains.\n   - After highlight ends → emit `highlight_end` → **freeze** board briefly (300ms) to collect `kinh_claims`.\n\n3. **Kinh Verification:**\n   - Collect all `userIds` who called Kinth within freeze window → Redis sorted set.\n   - For each claimant:\n     - Check each grain on their card: is the corresponding number in `drawn_numbers`? All must be drawn.\n     - If any grain on number not yet drawn → invalid.\n   - Compute:\n     - Valid winners: each receives `(totalPot / numValid)` coins.\n     - Invalid claimants: each pays `roomBet` to *each remaining player* (including other invalid? Clarify — typically penalty to all who did NOT call invalidly). Implementation: penalty distributed equally among all non-calling players? Or to all other players? We'll follow PRD: \"đền bằng mức cược của phòng cho mỗi người chơi còn lại\" — so each invalid pays `betAmount` to every other player in the room (including other invalid?). That would be circular if both invalid. Typically penalty goes to the house (của phòng) or to valid players. Let's interpret: \"đền ... cho mỗi người chơi còn lại\" meaning to each other player. If two invalid, they pay each other? That's net zero. Safer: invalid pays `betAmount * (numPlayers - 1)` to the *pool* which is then distributed to valid winners? But PRD says \"thưởng từ tất cả người thua\" — valid winners get pot from all losers. So losers are those who called invalid Kinh? Actually loser is everyone who didn't correctly complete row. In traditional Lô Tô, if you call false, you pay each other player. That's consistent. So each invalid player pays `betAmount` to *each other player* (including other invalids). That means if two invalids, they each pay the other → net zero between them, but they both also pay to valid winners. We'll implement exactly that: invalid claimant transfers `betAmount` to every other player in the room.\n   - Compute final balances atomically in DB transaction.\n\n4. **Settlement:**\n   - Update `room_players.final_balance`.\n   - Log all coin transactions (`coin_transactions` table).\n   - Broadcast `game_settled` with results (for UI animation).\n   - Room status → `settled`; players can exit to lobby.\n\n### Concurrent Kinh Handling\n\n- Freeze window: 500ms after `highlight_end`.\n- All `call_kinh` events received during freeze are added to `room:{roomId}:kinh_claims` (Redis SADD).\n- After freeze, server processes all claims in one batch.\n\n---\n\n## 7. Anti-Cheat & Integrity\n\n- **Balance lock:** `betAmount` reserved at join; cannot place grain if insufficient balance.\n- **Server-side validation:**\n  - `place_grain` validates cell corresponds to number already drawn (no future placement allowed, but late placement allowed on already-drawn numbers? PRD says \"người chơi vẫn có thể đặt muộn (theo trí nhớ) bất cứ lúc nào\" — so yes, after number drawn, grain can be placed anytime. But server checks that the number is indeed in `drawn_numbers`.\n  - `call_kinh` only allowed if player's current row completeness matches drawn numbers.\n- **Rate limiting:** Per-user action limits (max 10 grain placements per second, 1 Kinh call per round) using Redis counters.\n- **Replay protection:** Each `place_grain` includes a client-generated nonce to prevent replay attacks.\n- **Audit log:** All game actions logged to `game_history` with timestamps for potential dispute review.\n\n---\n\n## 8. Testing Strategy\n\n### Unit (Jest)\n- Card position mapping utils.\n- Kinh validation algorithm (row completeness check).\n- Coin transaction calculation (penalty distribution).\n- Balance update functions.\n\n### Integration (Socket.io mocks)\n- Room creation flow.\n- Number draw and broadcast.\n- Freeze window and claim collection.\n- Settlement logic with multiple players (including edge cases: all valid, all invalid, mix).\n\n### E2E (Cypress)\n- Single-player join + watch game (spectator mode? Not required).\n- 2-player room: full game loop, verify balances pre/post.\n- 4-player concurrent Kinh: all valid, split pot; all invalid, massive penalties.\n- Network lag simulation: ensure eventual consistency.\n- Disconnection: player drops mid-game, balance still locked correctly.\n- Chat messages appear.\n\nCI: GitHub Actions runs Jest + Cypress on push to main.\n\n---\n\n## 9. Infrastructure & Deployment\n\n### Development (Local)\n\n```bash\n# Backend\ncd server\nnpm install\ndocker compose up -d  # PostgreSQL + Redis\nnpm run dev  # hot reload\n\n# Frontend\ncd client\nnpm install\nnpm start  # localhost:3000 (connects to localhost:3001 WS)\n```\n\n### Staging / Free Tier\n\n- **Frontend:** Vercel project linked to GitHub repo. Auto-deploy from `main` to `lotto-game.vercel.app`.\n- **Backend:** Railway.app (or Render) with Dockerfile. Exposes port 3001. Free tier with 512MB-1GB RAM, 5h monthly sleep acceptable for testing.\n- **DB:** Supabase free tier (PostgreSQL) + Upstash free Redis (10K commands/day).\n- **Env:** `.env` with DB URLs, JWT secret, etc.\n\n### Production (Zalo Mini App)\n\n- **Backend:** Railway/Render hobby plan ($5–10/mo) — always-on, no sleep.\n- **Frontend:** Build for Zalo Mini App:\n  ```\n  npm run build:zalo  # outputs to dist/zalo/\n  ```\n  Upload to Zalo Mini App console, configure server domain (HTTPS WSS).\n- **Database:** Upgrade Supabase to Pro ($25/mo) for higher limits, or switch to Neon serverless.\n- **Monitoring:** Add basic logging (Winston) + health endpoint (`/healthz`).\n\n---\n\n## 10. Phase Plan for ClawTeam\n\nWe will decompose into independent, parallelizable tasks for ClawTeam workers. Each worker will be assigned a bounded scope (a single component or service). Workers will self-review, then cross-review, then final review by orchestrator.\n\n### Phase 1: Foundation (2 weeks)\n\n1. **Backend scaffolding** (Node.js + Express + Socket.io + Docker)\n2. **Database setup** (PostgreSQL schema + Redis integration)\n3. **Auth service** (JWT, anonymous user creation, Zalo OAuth placeholder)\n\n### Phase 2: Core Gameplay (2 weeks)\n\n4. **Room management** (create/join/ready/leave)\n5. **Number draw engine** (randomization, broadcast, highlight timer)\n6. **Grain placement** (server validation, board state updates)\n7. **Kinh verification & settlement** (concurrent claims, balance updates, transaction logging)\n\n### Phase 3: Frontend Game UI (2 weeks)\n\n8. **React app setup** (Vite, Zalo adapter, routing)\n9. **Lobby components** (room list, create modal, waiting room)\n10. **Game board UI** (LottoCard, NumberBag, RiceGrain with Framer Motion)\n11. **In-game HUD** (players panel, Kinh button, chat)\n\n### Phase 4: Economy, Social & Polish (2 weeks)\n\n12. **Coin economy system** — daily bonus, faucet management, anti-inflation\n13. **Achievements system** — track milestones (e.g., \"First Win\", \"5 Wins in a Row\", \"Concurrent Kinh with 3 Players\") and grant coin rewards\n14. **Spin wheel mini-game** — daily free spin for coin prizes (non-profit, fun engagement)\n15. **Chat system** (basic text chat)\n16. **Profile & stats** (view balance, history, achievement badges)\n17. **Testing suite** (Jest + Cypress full coverage)\n18. **Docker & deployment** (compose files, CI/CD, free tier config)\n\n### Phase 5: Optional (Future)\n\n19. **Audio integration** (TTS + SFX)\n20. **Advanced features** (tournament mode, friend list, invite via Zalo, spectator mode, AI bots)\n21. **Zalo-specific integrations** (share to feed, invite friends, deep linking)\n22. **Admin panel** (moderation, analytics, coin adjustment)\n\n---\n\n## 11. Risks & Mitigations\n\n| Risk | Mitigation |\n|------|------------|\n| WebSocket scaling on free tier | Use Redis adapter for multi-process; monitor connection count; upgrade if needed |\n| Race conditions in concurrent Kinh | Atomic Redis operations + transaction; thorough E2E tests |\n| Balance manipulation (client-side tampering) | Server-authoritative; pre/post balance snapshots; audit log |\n| Zalo Mini App packaging issues | Start with web MVP first; test on Zalo dev tools early |\n| Free tier limits (Upstash Redis 10K/day) | Optimize commands; use PostgreSQL for some room state if needed; upgrade cheaply |\n\n---\n\n## 12. Success Criteria\n\n- ✅ Full game loop: create room → join → draw numbers → place grains → call Kinh → settle → correct balances.\n- ✅ Concurrent Kinh handling (multiple winners) works reliably.\n- ✅ No cheating via client manipulation.\n- ✅ Responsive UI ≥ 30 FPS on mid-range mobile.\n- ✅ Deployable to Vercel + Railway free tier and runs for at least 10 concurrent players.\n- ✅ Test coverage: unit 80%+, integration critical paths, E2E user journeys.\n- ✅ Ready for Zalo Mini App integration (build script and config ready).\n\n---\n\n## 13. Open Questions (for user)\n\n1. **Penalty distribution exact rule:** When multiple players call invalid Kinh, does each invalid pay `betAmount` to *every other player* (including other invalids)? This yields net-zero between two invalids but they both pay to valids. Confirm: Yes, follow traditional Lô Tô rule: false caller pays each other player. (We implemented that).\n2. **Chat moderation:** Should we implement any profanity filter or moderation for Zalo Mini App? MVP: no filter; production: add simple word blacklist.\n3. **Daily bonus implementation:** We'll implement a simple `/claim-daily` endpoint that grants coins once per 24h. Any other faucets (achievements, spin wheel) in v1? Keep minimal — only daily login for v1.\n\nPlease review this spec. Once approved, I will invoke `writing-plans` skill to generate detailed implementation plan, then spawn ClawTeam workers following the 3-tier review process you specified.\n\n---\n\n**Next steps:**  \n1. User review and approval of this spec.  \n2. Write design doc to `docs/superpowers/specs/2026-03-31-lotto-game-design.md`.  \n3. Invoke `writing-plans` to produce task breakdown.  \n4. Spawn ClawTeam workers per phase, assign independent tasks.  \n5. Workers self-review → cross-review → Sagi final review → merge.\n"}],"isError":false,"timestamp":1774946939929}}

sign JWT with payload `{ userId, tempId, type: 'anonymous' }`\n  - `verifyToken(token)` — verify JWT secret, return payload\n- [ ] **Step 3: Implement auth.middleware** that extracts Bearer token, calls verifyToken, attaches `req.user`\n- [ ] **Step 4: Implement auth.route**:\n  - POST `/api/auth/anonymous` → creates anonymous account, returns `{ token, user: { id, coins } }`\n  - GET `/api/auth/me` → returns user from token\n- [ ] **Step 5: Wire up server** to use routes and middleware\n- [ ] **Step 6: Run tests** — pass\n- [ ] **Step 7: Commit** \"feat: anonymous JWT auth\"\n\n### Task 4: Socket.io Server Setup\n\n**Files:**\n- Create: `server/socket/socketServer.js`\n- Create: `server/socket/handlers/roomHandlers.js`\n- Create: `server/socket/handlers/gameHandlers.js`\n- Modify: `server/index.js` to initialize Socket.io and attach handlers\n\n- [ ] **Step 1: Write failing test** — `server/socket/socketServer.test.js` using `socket.io-client` to connect, emit `create_room`, expect `room_created` event (mock DB)\n- [ ] **Step 2: Implement socketServer.js**:\n  - `setupSocket(server)` attaches Socket.io to HTTP server\n  - uses `socket.use(authMiddleware)` to authenticate JWT\n  - registers namespaces (none, default)\n- [ ] **Step 3: Implement roomHandlers.js**:\n  - `onCreateRoom(socket, data)` validates betAmount, maxPlayers, highlightSeconds; generates room code; creates room record; joins socket to room; emits `room_created`\n  - `onJoinRoom(socket, {roomCode})` validates code; adds player to room_players; joins socket room; emits `room_joined` with state\n  - `onReady(socket)` marks player ready; if all ready, transitions to `playing` after countdown\n- [ ] **Step 4: Implement gameHandlers.js** (stubs):\n  - `onPlaceGrain` — validations (server-authoritative) will be added later\n  - `onCallKinh` — stub: push to Redis claims set\n  - `onChat` — broadcast to room\n- [ ] **Step 5: Wire in socketServer to index.js**\n- [ ] **Step 6: Run test** — pass\n- [ ] **Step 7: Commit** \"feat: socket.io server and room/game handlers\"\n\n### Task 5: Rate Limiting Middleware\n\n**Files:**\n- Create: `server/middleware/rateLimit.js`\n\n- [ ] **Step 1: Write failing test** — `server/middleware/rateLimit.test.js`:\n  - Simulate 10 requests from same user within second;

test failure when insufficient coins\n- [ ] **Step 2: Implement coinService**:\n  - `reserveBet(userId, amount)` — atomic: UPDATE users SET coins = coins - amount WHERE id=$1 AND coins >= amount; if row count 0 throw insufficient; then INSERT coin_transaction (type=BET_PLACED, amount=-amount, balance_after = (SELECT coins FROM users WHERE id=$1))\n  - `refundBet(userId, amount)` — opposite (used on leave before start)\n  - `applyWin(userId, amount, roomId)` — add coins, log KINH_WON\n  - `applyPenalty(userId, amount, roomId)` — subtract coins, log KINH_PENALTY\n- [ ] **Step 3: Wire join_room** to call `reserveBet` when player joins; if fails, emit error and reject join\n- [ ] **Step 4: Run tests** — pass\n- [ ] **Step 5: Commit** \"feat: coin reservation on room join\"\n\n---\n\n## Phase 2: Core Gameplay Engine — 2 weeks\n\n### Task 7: Number Draw Engine\n\n**Files:**\n- Create: `server/services/drawEngine.js`\n- Create: `server/services/drawEngine.test.js`\n- Modify: `server/socket/handlers/gameHandlers.js` (add `startGame`)\n\n- [ ] **Step 1: Write failing test** — test `shuffleNumbers()` returns array of 90 unique numbers; test `drawNext()` returns number not previously drawn\n- [ ] **Step 2: Implement drawEngine**:\n  - `createDeck()` returns shuffled numbers 1..90 using Fisher-Yates\n  - `DrawSession` class: holds remaining deck, drawn array, current index. Method `drawNext()` returns next number, stores in drawn array with timestamp\n- [ ] **Step 3: Implement `startGame(roomId)` handler**:\n  - Fetch room players; verify all ready or owner forced start\n  - Create DrawSession for room (store in Redis: `room:{roomId}:draw_state` = JSON with deck)\n  - Set room status = 'playing'; broadcast `game_start` with empty drawnNumbers\n  - Begin async loop: for each number, `setTimeout` highlightSeconds*1000, then emit `number_drawn` and `highlight_end`\n- [ ] **Step 4: Run tests** — pass\n- [ ] **Step 5: Commit** \"feat: number draw engine with broadcast\"\n\n### Task 8: Rice Grain Placement Validation\n\n**Files:**\n- Create: `server/services/boardService.js`\n- Create: `server/services/boardService.test.js`\n- Modify: `server/socket/handlers/gameHandlers.js` (onPlaceGrain)\n\n- [ ] **Step 1: Write failing test** — test `canPlaceGrain(userId, row, col, drawnNumbers)` returns false if column's number not in drawnNumbers; true if drawn; also check max 5 grains per row\n- [ ] **Step 2: Implement boardService**:\n  - `getNumberForCell(row, col)` returns number (1–90) based on standard Lô Tô card layout (3 rows × 9 cols, 5 numbers per row distributed by decades)\n  - `isNumberDrawn(num, drawnNumbers)` — includes in array check\n  - `canPlaceGrain(userId, row, col, drawnNumbers, roomPlayers)` — ensures user has not exceeded 5 grains per row; cell not already occupied by that user; number drawn; bet reserved sufficient\n  - `placeGrain(userId, row, col)` — records grain placement (in Redis set `room:{roomId}:player:{userId}:grains` serialized) and broadcast to room\n- [ ] **Step 3: in onPlaceGrain**, validate with boardService; if valid, update Redis and broadcast `grain_placed` event with position; if invalid, emit error\n- [ ] **Step 4: Run tests** — pass\n- [ ] **Step 5: Commit** \"feat: rice grain placement validation\"\n\n### Task 9: Concurrent Kinh Handling\n\n**Files:**\n- Modify: `server/socket/handlers/gameHandlers.js` (onCallKinh)\n- Create: `server/services/kinhService.js`\n- Create: `server/services/kinhService.test.js`\n\n- [ ] **Step 1: Write failing test** — test `validateKinh(userId, roomId)` returns true if all rows that have grains fully match drawnNumbers; false otherwise\n- [ ] **Step 2: Implement `validateKinh`**:\n  - Get user's grains from Redis; compute rows where they have exactly 5 grains; check every grain's number is in drawnNumbers\n  - Returns object `{ valid: boolean, rowsCompleted: number[] }`\n- [ ] **Step 3: Implement onCallKinh**:\n  - When received, add to Redis sorted set `room:{roomId}:kinh_claims` with score=Date.now()\n  - Broadcast `kinh_claim` to room so UI shows pending badge\n  - Do not respond immediately; wait for freeze window end\n- [ ] **Step 4: Modify draw engine**:\n  - After `highlight_end` emitted, set a short freeze timeout (500ms)\n  - After freeze, collect all userIds from Redis sorted set (score within window); clear set; process all claims via `processKinhClaims(roomId, claims)`\n- [ ] **Step 5: Implement processKinhClaims**:\n  - For each claimant, run `validateKinh`\n  - Separate into validWinners and invalidClaimants\n  - Compute totalPot = sum of all bets (roomBet * numPlayers)\n  - Compute reward per valid = totalPot / validCount (integer math; any remainder left in pot?

Rules: Column 0 = numbers 1-9; column 1 = 10-19; ... column 8 = 81-90? Actually Lô Tô: 9 columns represent tens: 1-9,10-19,...,80-90. Each column has 3 rows, but only 5 numbers per row across columns. Standard layout: Each row contains 5 numbers placed in specific column positions based on decade. We need precise mapping. Quick reference: traditional Lô Tô card:\n  - Columns: 1 (1-9), 2 (10-19), 3 (20-29), 4 (30-39), 5 (40-49), 6 (50-59), 7 (60-69), 8 (70-79), 9 (80-90)\n  - Rows: top, middle, bottom. Each row has 5 numbers; the distribution across columns follows rules: each row includes exactly 5 numbers from 5 different columns. There are standard patterns but we can simplify: randomly assign 5 numbers (from the column's range) to each row, ensuring each column used at least once across rows? For simplicity, we can predefine a fixed pattern for all cards: each card identical layout. Let's define a static mapping array `CELL_NUMBERS[3][9]` where each cell has a number (1-90) or null. Only 15 cells are numbers; others empty visual. We'll create a deterministic layout (same for all players) to avoid needing dynamic generation. We'll hardcode a valid Lô Tô card pattern: e.g., \nRow1: 1,11,21,31,41 at columns 1,2,3,4,5; others empty.\nRow2: 51,61,71,81,91? Wait 91 doesn't exist. Let's design properly: We need 5 numbers per row across 9 columns; each column appears at most once per row. Use this pattern (just an example):\nRow1: col0=1, col1=11, col2=25, col3=33, col4=44, others null\nRow2: col0=5, col1=17, col2=28, col4=49, col6=62\nRow3: col1=20, col3=39, col5=58, col7=79, col8=90\nWe'll make a specific valid layout and hardcode it. It's not random; all players have same card pattern. That's fine for MVP.\nImplement `getNumberForCell(row, col)` returns that hardcoded number or null.\n- [ ] **Step 3: Implement LottoCard component**:\n  - Renders a 3x9 grid using CSS grid.\n  - For each cell: if number exists, clickable area; if null, empty placeholder with retro styling.\n  - Shows rice grain overlay if cell is in `grains` set (from GameContext)\n  - If cell's number is in `drawnNumbers`, highlight with CSS class\n  - onClick calls `placeGrain(row, col)`\n- [ ] **Step 4: Implement GameBoard**:\n  - Contains LottoCard, NumberBag animation, current number display, Kinh button, players panel\n  - Uses Framer Motion for NumberBag (shake) when number being drawn\n- [ ] **Step 5: Run tests** — pass\n- [ ] **Step 6: Commit** \"feat: Lotto card and game board UI\"\n\n### Task 15: Framer Motion Animations\n\n**Files:**\n- Modify: `client/src/components/Game/NumberBag.jsx` (new file)\n- Modify: `client/src/components/Game/RiceGrain.jsx` (new file)\n- Modify: `client/src/styles/retroTheme.js`\n\n- [ ] **Step 1: Write failing test** (visual, manual) — skip unit; will verify visually\n- [ ] **Step 2: Create NumberBag component** with animation using Framer Motion: while `isShaking` true, rotate and scale; while `drawing` emits number ball with motion\n- [ ] **Step 3: Create RiceGrain component** — when placed, animate drop (y: -100 to 0 with bounce) using `motion.div`\n- [ ] **Step 4: Create retroTheme.js** with color palette: nâu gỗ, vàng ố, đỏ đất, xanh lá cũ; fonts: handwriting retro; textures optional (use CSS patterns)\n- [ ] **Step 5: Apply retro theme to components** (buttons, cards)\n- [ ] **Step 6: Manual QA**: run app, verify animations smooth (≥30fps)\n- [ ] **Step 7: Commit** \"feat: animations and retro styling\"\n\n### Task 16: In-Game HUD & Controls\n\n**Files:**\n- Create: `client/src/components/Game/PlayersPanel.jsx`\n- Create: `client/src/components/Game/KinhButton.jsx`\n- Create: `client/src/components/Game/ChatPanel.jsx`\n- Modify: `client/src/components/Game/GameBoard.jsx` to include these\n\n- [ ] **Step 1: Write failing test** — `client/src/components/Game/KinhButton.test.jsx`: test disabled when not playing; click calls `callKinh`\n- [ ] **Step 2: Implement PlayersPanel**:\n  - Shows list: avatar, name, ready status, balance (pre-game), grains count\n  - Updates via GameContext\n- [ ] **Step 3: Implement KinhButton**:\n  - Visible only during playing and after user has completed at least one row (check row completeness from grains)\n  - Clicking emits `callKinh`; button disabled after click to prevent spam\n  - Shows countdown timer if freeze window active?

Create `server/services/auth.js` that exports:\n   - `generateTempUserId()` — returns UUID v4 (use `uuid` package)\n   - `createAnonymousUser()` — inserts a new user with `temp_id` and `coins=1000` into `users` table using `db.query`. Returns `{ id, temp_id, coins }`.\n   - `verifyToken(token)` — verifies JWT using `process.env.JWT_SECRET`, returns payload. Throws if invalid.\n\n2. Create `server/middleware/auth.js` that exports a function `authMiddleware`:\n   - Extracts Bearer token from `Authorization` header (or Socket.io handshake auth)\n   - Calls `authService.verifyToken(token)`\n   - Attaches `req.user = payload` (or `socket.data.user` for Socket.io)\n   - If token invalid, responds with 401 or emits error for socket\n\n3. Create `server/routes/auth.js` that registers two endpoints:\n   - `POST /api/auth/anonymous`: calls `createAnonymousUser()`, creates JWT (sign with payload `{ userId, tempId, type: 'anonymous' }`), returns `{ token, user }`\n   - `GET /api/auth/me`: protected by `authMiddleware`; returns user data (id, coins, temp_id, zalo_id if any)\n\n4. Modify `server/index.js` (or `server/app.js` if exists) to:\n   - Use `cors()` middleware\n   - Use `helmet()`\n   - Parse JSON bodies\n   - Register `/api/auth` routes\n   - If not exists, create basic Express app and HTTP server for Socket.io to attach\n\n5. Write failing test `server/services/auth.test.js`:\n   - Test `createAnonymousUser` creates user in DB and returns fields\n   - Test `verifyToken` works with a signed token, throws with wrong secret\n   - Use in-memory Postgres? Actually use test DB; we can assume docker is running. But to be safe, tests can hit the same DB; they will create and read real records. That's fine for now.\n\n6. Run tests (`npm test` if configured; otherwise node --test or jest). Ensure they pass.\n7. Commit with message: \"feat: anonymous JWT auth\"\n\n**Note:** You can use Jest for tests. If no jest config yet, create `server/jest.config.js` minimal.\n\n**Output:** After committing, return git status and commit hash.","timeoutSeconds":300}}],"api":"openai-completions","provider":"openrouter","model":"stepfun/step-3.5-flash:free","usage":{"input":915,"output":1409,"cacheRead":81024,"cacheWrite":0,"totalTokens":83348,"cost":{"input":0,"output":0,"cacheRead":0,"cacheWrite":0,"total":0}},"stopReason":"toolUse","timestamp":1774948769725,"responseId":"gen-1774948770-IYa6RSwiUN3WGIS0Gghu"}}
