+## Codex Integration
+
+The `codex` skill enables Claude Code to delegate code execution to Codex CLI.
+
+### Usage in Workflows
+
+```bash
+# Codex is invoked via the skill
+codex-wrapper - <<'EOF'
+implement @src/auth.ts with JWT validation
+EOF
+```
+
+### Parallel Execution
+
+```bash
+codex-wrapper --parallel <<'EOF'
+---TASK---
+id: backend_api
+workdir: /project/backend
+---CONTENT---
+implement REST endpoints for /api/users
+
+---TASK---
+id: frontend_ui
+workdir: /project/frontend
+dependencies: backend_api
+---CONTENT---
+create React components consuming the API
+EOF
+```
+
+### Install Codex Wrapper
+
+```bash
+# Automatic (via dev module)
+python3 install.py --module dev
+
+# Manual
+bash install.sh
+```
+
+#### Windows
+
+Windows installs place `codex-wrapper.exe` in `%USERPROFILE%\bin`.
+
+```powershell
+# PowerShell (recommended)
+powershell -ExecutionPolicy Bypass -File install.ps1
+
+# Batch (cmd)
+install.bat
+```
+
+**Add to PATH** (if installer doesn't detect it):
+
+```powershell
+# PowerShell - persistent for current user
+[Environment]::SetEnvironmentVariable('PATH', "$HOME\bin;" + [Environment]::GetEnvironmentVariable('PATH','User'), 'User')
+
+# PowerShell - current session only
+$Env:PATH = "$HOME\bin;$Env:PATH"
+```
+
+```batch
+REM cmd.exe - persistent for current user
+setx PATH "%USERPROFILE%\bin;%PATH%"
+```
+
+---
+
+## Workflow Selection Guide
+
+| Scenario | Recommended Workflow |
+|----------|---------------------|
+| New feature with tests | `/dev` |
+| Quick bug fix | `/debug` or `/code` |
+| Large multi-sprint feature | `/bmad-pilot` |
+| Prototype or POC | `/requirements-pilot` |
+| Code review | `/review` |
+| Performance issue | `/optimize` |
+
+---
+
+## Troubleshooting
+
+### Common Issues

+
+## Codex 集成
+
+`codex` 技能使 Claude Code 能够将代码执行委托给 Codex CLI。
+
+### 工作流中的使用
+
+```bash
+# 通过技能调用 Codex
+codex-wrapper - <<'EOF'
+在 @src/auth.ts 中实现 JWT 验证
+EOF
+```
+
+### 并行执行
+
+```bash
+codex-wrapper --parallel <<'EOF'
+---TASK---
+id: backend_api
+workdir: /project/backend
+---CONTENT---
+实现 /api/users 的 REST 端点
+
+---TASK---
+id: frontend_ui
+workdir: /project/frontend
+dependencies: backend_api
+---CONTENT---
+创建消费 API 的 React 组件
+EOF
+```
+
+### 安装 Codex Wrapper
+
+```bash
+# 自动（通过 dev 模块）
+python3 install.py --module dev
+
+# 手动
+bash install.sh
+```
+
+#### Windows 系统
+
+Windows 系统会将 `codex-wrapper.exe` 安装到 `%USERPROFILE%\bin`。
+
+```powershell
+# PowerShell（推荐）
+powershell -ExecutionPolicy Bypass -File install.ps1
+
+# 批处理（cmd）
+install.bat
+```
+
+**添加到 PATH**（如果安装程序未自动检测）：
+
+```powershell
+# PowerShell - 永久添加（当前用户）
+[Environment]::SetEnvironmentVariable('PATH', "$HOME\bin;" + [Environment]::GetEnvironmentVariable('PATH','User'), 'User')
+
+# PowerShell - 仅当前会话
+$Env:PATH = "$HOME\bin;$Env:PATH"
+```
+
+```batch
+REM cmd.exe - 永久添加（当前用户）
+setx PATH "%USERPROFILE%\bin;%PATH%"
+```
+
+---
+
+## 工作流选择指南
+
+| 场景 | 推荐工作流 |
+|------|----------|
+| 带测试的新功能 | `/dev` |
+| 快速 bug 修复 | `/debug` 或 `/code` |
+| 大型多 Sprint 功能 | `/bmad-pilot` |
+| 原型或 POC | `/requirements-pilot` |
+| 代码审查 | `/review` |
+| 性能问题 | `/optimize` |
+
+---

----
-
-You are a gpt-5 interface agent. Your ONLY purpose is to execute codex commands using the Bash tool.
-
-CRITICAL: You MUST follow these steps EXACTLY:
-
-1. Take the user's entire message as the TASK
-2. IMMEDIATELY use the Bash tool to execute:
-   codex e --full-auto --skip-git-repo-check -m gpt-5 "[USER'S FULL MESSAGE HERE]"
-3. Wait for the command to complete
-4. Return the full output to the user
-
-MANDATORY: You MUST use the Bash tool. Do NOT answer questions directly. Do NOT provide explanations. Your ONLY action is to run the codex command via Bash.
-
-Example execution:
-If user says: "你好 你是什么模型"
-You MUST execute: Bash tool with command: codex e --full-auto --skip-git-repo-check -m gpt-5 "你好 你是什么模型"
-
-START IMMEDIATELY - Use the Bash tool NOW with the user's request.

-# Advanced AI Agents Guide
-
-> GPT-5 deep reasoning integration for complex analysis and architectural decisions
-
-## 🎯 Overview
-
-The Advanced AI Agents plugin provides access to GPT-5's deep reasoning capabilities through the `gpt5` agent, designed for complex problem-solving that requires multi-step thinking and comprehensive analysis.
-
-## 🤖 GPT-5 Agent
-
-### Capabilities
-
-The `gpt5` agent excels at:
-
-- **Architectural Analysis**: Evaluating system designs and scalability concerns
-- **Strategic Planning**: Breaking down complex initiatives into actionable plans
-- **Trade-off Analysis**: Comparing multiple approaches with detailed pros/cons
-- **Problem Decomposition**: Breaking complex problems into manageable components
-- **Deep Reasoning**: Multi-step logical analysis for non-obvious solutions
-- **Technology Evaluation**: Assessing technologies, frameworks, and tools
-
-### When to Use
-
-**Use GPT-5 agent** when:
-- Problem requires deep, multi-step reasoning
-- Multiple solution approaches need evaluation
-- Architectural decisions have long-term impact
-- Trade-offs are complex and multifaceted
-- Standard agents provide insufficient depth
-
-**Use standard agents** when:
-- Task is straightforward implementation
-- Requirements are clear and well-defined
-- Quick turnaround is priority
-- Problem is domain-specific (code, tests, etc.)
-
-## 🚀 Usage
-
-### Via `/think` Command
-
-The easiest way to access GPT-5:
-
-```bash
-/think "Analyze scalability bottlenecks in current microservices architecture"
-/think "Evaluate migration strategy from monolith to microservices"
-/think "Design data synchronization approach for offline-first mobile app"
-```
-
-### Direct Agent Invocation
-
-For advanced usage:
-
-```bash
-# Use @gpt5 to invoke the agent directly
-@gpt5 "Complex architectural question or analysis request"
-```
-
-## 💡 Example Use Cases
-
-### 1. Architecture Evaluation
-
-```bash
-/think "Current system uses REST API with polling for real-time updates. 
-Evaluate whether to migrate to WebSocket, Server-Sent Events, or GraphQL 
-subscriptions. Consider: team experience, existing infrastructure, client 
-support, scalability, and implementation effort."
-```
-
-**GPT-5 provides**:
-- Detailed analysis of each option
-- Pros and cons for your specific context
-- Migration complexity assessment
-- Performance implications
-- Recommended approach with justification
-
-### 2. Migration Strategy
-
-```bash
-/think "Plan migration from PostgreSQL to multi-region distributed database. 
-System has 50M users, 200M rows, 1000 req/sec. Must maintain 99.9% uptime. 
-What's the safest migration path?"
-```
-
-**GPT-5 provides**:
-- Step-by-step migration plan
-- Risk assessment for each phase
-- Rollback strategies
-- Data consistency approaches
-- Timeline estimation
-
-### 3. Problem Decomposition
-
-```bash
-/think "Design a recommendation engine that learns user preferences, handles 
-cold start, provides explainable results, and scales to 10M users. Break this 
-down into implementation phases with clear milestones."
-```
-
-**GPT-5 provides**:
-- Problem breakdown into components
-- Phased implementation plan
-- Technical approach for each phase
-- Dependencies between phases
-- Success criteria and metrics
-
-### 4. Technology Selection
-
-```bash
-/think "Choosing between Redis, Memcached, and Hazelcast for distributed 
-caching. System needs: persistence, pub/sub, clustering, and complex data 
-structures. Existing stack: Java, Kubernetes, AWS."
-```
-
-**GPT-5 provides**:
-- Comparison matrix across requirements
-- Integration considerations
-- Operational complexity analysis
-- Cost implications
-- Recommendation with rationale
-
-### 5. Performance Optimization
-
-```bash
-/think "API response time increased from 100ms to 800ms after scaling from 
-100 to 10,000 users. Database queries look optimized. What are the likely 
-bottlenecks and systematic approach to identify them?"
-```
-
-**GPT-5 provides**:
-- Hypothesis generation (N+1 queries, connection pooling, etc.)
-- Systematic debugging approach
-- Profiling strategy
-- Likely root causes ranked by probability
-- Optimization recommendations
-
-## 🎨 Integration with BMAD
-
-### Enhanced Code Review
-
-BMAD's `bmad-review` agent can optionally use GPT-5 for deeper analysis:
-
-**Configuration**:
-```bash
-# Enable enhanced review mode (via environment or BMAD config)
-BMAD_REVIEW_MODE=enhanced /bmad-pilot "feature description"
-```
-
-**What changes**:
-- Standard review: Fast, focuses on code quality and obvious issues
-- Enhanced review: Deep analysis including:
-  - Architectural impact
-  - Security implications
-  - Performance considerations
-  - Scalability concerns
-  - Design pattern appropriateness
-
-### Architecture Phase Support
-
-Use `/think` during BMAD architecture phase:
-
-```bash
-# Start BMAD workflow
-/bmad-pilot "E-commerce platform with real-time inventory"
-
-# During Architecture phase, get deep analysis

-
-## 📋 Best Practices
-
-### 1. Provide Complete Context
-
-**❌ Insufficient**:
-```bash
-/think "Should we use microservices?"
-```
-
-**✅ Complete**:
-```bash
-/think "Current monolith: 100K LOC, 8 developers, 50K users, 200ms avg 
-response time. Pain points: slow deployments (1hr), difficult to scale 
-components independently. Should we migrate to microservices? What's the 
-ROI and risk?"
-```
-
-### 2. Ask Specific Questions
-
-**❌ Too broad**:
-```bash
-/think "How to build a scalable system?"
-```
-
-**✅ Specific**:
-```bash
-/think "Current system handles 1K req/sec. Need to scale to 10K. Bottleneck 
-is database writes. Evaluate: sharding, read replicas, CQRS, or caching. 
-Database: PostgreSQL, stack: Node.js, deployment: Kubernetes."
-```
-
-### 3. Include Constraints
-
-Always mention:
-- Team skills and size
-- Timeline and budget
-- Existing infrastructure
-- Business requirements
-- Technical constraints
-
-**Example**:
-```bash
-/think "Design real-time chat system. Constraints: team of 3 backend 
-developers (Node.js), 6-month timeline, AWS deployment, must integrate 
-with existing REST API, budget for managed services OK."
-```
-
-### 4. Request Specific Outputs
-
-Tell GPT-5 what format you need:
-
-```bash
-/think "Compare Kafka vs RabbitMQ for event streaming. 
-Provide: comparison table, recommendation, migration complexity from current 
-RabbitMQ setup, and estimated effort in developer-weeks."
-```
-
-### 5. Iterate and Refine
-
-Follow up for deeper analysis:
-
-```bash
-# Initial question
-/think "Evaluate caching strategies for user profile API"
-
-# Follow-up based on response
-/think "You recommended Redis with write-through caching. How to handle 
-cache invalidation when user updates profile from mobile app?"
-```
-
-## 🔧 Technical Details
-
-### Sequential Thinking
-
-GPT-5 agent uses sequential thinking for complex problems:
-
-1. **Problem Understanding**: Clarify requirements and constraints
-2. **Hypothesis Generation**: Identify possible solutions
-3. **Analysis**: Evaluate each option systematically
-4. **Trade-off Assessment**: Compare pros/cons
-5. **Recommendation**: Provide justified conclusion
-
-### Reasoning Transparency
-
-GPT-5 shows its thinking process:
-- Assumptions made
-- Factors considered
-- Why certain options were eliminated
-- Confidence level in recommendations
-
-## 🎯 Comparison: GPT-5 vs Standard Agents
-
-| Aspect | GPT-5 Agent | Standard Agents |
-|--------|-------------|-----------------|
-| **Depth** | Deep, multi-step reasoning | Focused, domain-specific |
-| **Speed** | Slower (comprehensive analysis) | Faster (direct implementation) |
-| **Use Case** | Strategic decisions, architecture | Implementation, coding, testing |
-| **Output** | Analysis, recommendations, plans | Code, tests, documentation |
-| **Best For** | Complex problems, trade-offs | Clear tasks, defined scope |
-| **Invocation** | `/think` or `@gpt5` | `/code`, `/test`, etc. |

-## 💡 Advanced Patterns
-
-### Pre-Implementation Analysis
-
-```bash
-# 1. Deep analysis with GPT-5
-/think "Design approach for X with constraints Y and Z"
-
-# 2. Use analysis in BMAD workflow
-/bmad-pilot "Implement X based on approach from analysis"
-```
-
-### Architecture Validation
-
-```bash
-# 1. Get initial architecture from BMAD
-/bmad-pilot "Feature X"  # Generates 02-system-architecture.md
-
-# 2. Validate with GPT-5
-/think "Review architecture in .claude/specs/feature-x/02-system-architecture.md
-Evaluate for scalability, security, and maintainability"
-
-# 3. Refine architecture based on feedback
-```
-
-### Decision Documentation
-
-```bash
-# Use GPT-5 to document architectural decisions
-/think "Document decision to use Event Sourcing for order management.
-Include: context, options considered, decision rationale, consequences,
-and format as Architecture Decision Record (ADR)"

-name: BMAD
-description:
-  Orchestrate BMAD (PO → Architect → SM → Dev → QA).
-  PO/Architect/SM run locally; Dev/QA via bash Codex CLI. Explicit approval gates and repo-aware artifacts.
----
-
-# BMAD Output Style
-
-<role>
-You are the BMAD Orchestrator coordinating a full-stack Agile workflow with five roles: Product Owner (PO), System Architect, Scrum Master (SM), Developer (Dev), and QA. You do not overtake their domain work; instead, you guide the flow, ask targeted questions, enforce approval gates, and save outputs when confirmed.
-
-PO/Architect/SM phases run locally as interactive loops (no external Codex calls). Dev/QA phases may use bash Codex CLI when implementation or execution is needed.
-</role>
-
-<important_instructions>
-1. Use UltraThink: hypotheses → evidence → patterns → synthesis → validation.
-2. Follow KISS, YAGNI, DRY, and SOLID principles across deliverables.
-3. Enforce approval gates (Phase 1–3 only): PRD ≥ 90; Architecture ≥ 90; SM plan confirmed. At these gates, REQUIRE the user to reply with the literal "yes" (case-insensitive) to save the document AND proceed to the next phase; any other reply = do not save and do not proceed. Phase 0 has no gate.
-4. Language follows the user’s input language for all prompts and confirmations.
-5. Retry Codex up to 5 times on transient failure; if still failing, stop and report clearly.
-6. Prefer “summarize + user confirmation” for long contexts before expansion; chunk only when necessary.
-7. Default saving is performed by the Orchestrator. In save phases Dev/QA may also write files. Only one task runs at a time (no concurrent writes).
-8. Use kebab-case `feature_name`. If no clear title, use `feat-YYYYMMDD-<short-summary>`.
-9. Store artifacts under `./.claude/specs/{feature_name}/` with canonical filenames.
-</important_instructions>
-
-<global_instructions>
-- Inputs may include options: `--skip-tests`, `--direct-dev`, `--skip-scan`.
-- Derive `feature_name` from the feature title; compute `spec_dir=./.claude/specs/{feature_name}/`.
-- Artifacts:
-  - `00-repo-scan.md` (unless `--skip-scan`)
-  - `01-product-requirements.md` (PRD, after approval)
-  - `02-system-architecture.md` (Architecture, after approval)
-  - `03-sprint-plan.md` (SM plan, after approval; skipped if `--direct-dev`)
-- Always echo saved paths after writing.
-</global_instructions>
-
-<coding_instructions>
-- Dev phase must execute tasks via bash Codex CLI: `codex e --full-auto --skip-git-repo-check -m gpt-5 "<TASK with brief CONTEXT>"`.
-- QA phase must execute tasks via bash Codex CLI: `codex e --full-auto --skip-git-repo-check -m gpt-5 "<TASK with brief CONTEXT>"`.
-- Treat `-m gpt-5` purely as a model parameter; avoid “agent” wording.
-- Keep Codex prompts concise and include necessary paths and short summaries.
-- Apply the global retry policy (up to 5 attempts); if still failing, stop and report.
-</coding_instructions>
-
-<result_instructions>
-- Provide concise progress updates between phases.
-- Before each approval gate, present: short summary + quality score (if applicable) + clear confirmation question.
-- Gates apply to Phases 1–3 (PO/Architect/SM) only. Proceed only on explicit "yes" (case-insensitive). On "yes": save to the canonical path, echo it, and advance to the next phase.
-- Any non-"yes" reply: do not save and do not proceed; offer refinement, re-ask, or cancellation options.
-- Phase 0 has no gate: save scan summary (unless `--skip-scan`) and continue automatically to Phase 1.
-</result_instructions>
-
-<thinking_instructions>
-- Identify the lowest-confidence or lowest-scoring areas and focus questions there (2–3 at a time max).
-- Make assumptions explicit and request confirmation for high-impact items.
-- Cross-check consistency across PRD, Architecture, and SM plan before moving to Dev.
-</thinking_instructions>
-
-<context>
-- Repository-aware behavior: If not `--skip-scan`, perform a local repository scan first and cache summary as `00-repo-scan.md` for downstream use.
-- Reference internal guidance implicitly (PO/Architect/SM/Dev/QA responsibilities), but avoid copying long texts verbatim. Embed essential behaviors in prompts below.
-</context>
-
-<workflows>
-1) Phase 0 — Repository Scan (optional, default on)
-   - Run locally if not `--skip-scan`.
-   - Task: Analyze project structure, stack, patterns, documentation, workflows using UltraThink.
-   - Output: succinct Markdown summary.
-   - Save and proceed automatically: write `spec_dir/00-repo-scan.md` and then continue to Phase 1 (no confirmation required).
-
-2) Phase 1 — Product Requirements (PO)
-   - Goal: PRD quality ≥ 90 with category breakdown.
-   - Local prompt:
-     - Role: Sarah (BMAD PO) — meticulous, analytical, user-focused.
-     - Include: user request; scan summary/path if available.
-     - Produce: PRD draft (exec summary, business objectives, personas, functional epics/stories+AC, non-functional, constraints, scope & phasing, risks, dependencies, appendix).
-     - Score: 100-point breakdown (Business Value & Goals 30; Functional 25; UX 20; Technical Constraints 15; Scope & Priorities 10) + rationale.
-     - Ask: 2–5 focused clarification questions on lowest-scoring areas.
-     - No saving during drafting.
-   - Loop: Ask user, refine, rescore until ≥ 90.
-   - Gate: Ask confirmation (user language). Only if user replies "yes": save `01-product-requirements.md` and move to Phase 2; otherwise stay here and continue refinement.
-
-3) Phase 2 — System Architecture (Architect)
-   - Goal: Architecture quality ≥ 90 with category breakdown.
-   - Local prompt:
-     - Role: Winston (BMAD Architect) — comprehensive, pragmatic; trade-offs; constraint-aware.
-     - Include: PRD content; scan summary/path.
-     - Produce: initial architecture (components/boundaries, data flows, security model, deployment, tech choices with justifications, diagrams guidance, implementation guidance).
-     - Score: 100-point breakdown (Design 30; Tech Selection 25; Scalability/Performance 20; Security/Reliability 15; Feasibility 10) + rationale.
-     - Ask: targeted technical questions for critical decisions.
-     - No saving during drafting.
-   - Loop: Ask user, refine, rescore until ≥ 90.
-   - Gate: Ask confirmation (user language). Only if user replies "yes": save `02-system-architecture.md` and move to Phase 3; otherwise stay here and continue refinement.
-
-4) Phase 3 — Sprint Planning (SM; skipped if `--direct-dev`)
-   - Goal: Actionable sprint plan (stories, tasks 4–8h, estimates, dependencies, risks).
-   - Local prompt:
-     - Role: BMAD SM — organized, methodical; dependency mapping; capacity & risk aware.
-     - Include: scan summary/path; PRD path; Architecture path.
-     - Produce: exec summary; epic breakdown; detailed stories (AC、tech notes、tasks、DoD); sprint plan; critical path; assumptions/questions (2–4)。
-     - No saving during drafting.
-   - Gate: Ask confirmation (user language). Only if user replies "yes": save `03-sprint-plan.md` and move to Phase 4; otherwise stay here and continue refinement.
-
-5) Phase 4 — Development (Dev)
-   - Goal: Implement per PRD/Architecture/SM plan with tests; report progress.
-   - Execute via bash Codex CLI (required):
-     - Command: `codex e --full-auto --skip-git-repo-check -m gpt-5 "Implement per PRD/Architecture/Sprint plan with tests; report progress and blockers. Context: [paths + brief summaries]."`
-     - Include paths: `00-repo-scan.md` (if exists), `01-product-requirements.md`, `02-system-architecture.md`, `03-sprint-plan.md` (if exists).
-     - Follow retry policy (5 attempts); if still failing, stop and report.
-   - Orchestrator remains responsible for approvals and saving as needed.
-
-6) Phase 5 — Quality Assurance (QA; skipped if `--skip-tests`)
-   - Goal: Validate acceptance criteria; report results.
-   - Execute via bash Codex CLI (required):
-     - Command: `codex e --full-auto --skip-git-repo-check -m gpt-5 "Create and run tests to validate acceptance criteria; report results with failures and remediation. Context: [paths + brief summaries]."`
-     - Include paths: same as Dev.
-     - Follow retry policy (5 attempts); if still failing, stop and report.

-name: Requirements Clarity
-description: Clarify ambiguous requirements through focused dialogue before implementation. Use when requirements are unclear, features are complex (>2 days), or involve cross-team coordination. Ask two core questions - Why? (YAGNI check) and Simpler? (KISS check) - to ensure clarity before coding.
----
-
-# Requirements Clarity Skill
-
-## Description
-
-Automatically transforms vague requirements into actionable PRDs through systematic clarification with a 100-point scoring system.
-
-## Activation
-
-Auto-activate when detecting vague requirements:
-
-1. **Vague Feature Requests**
-   - User says: "add login feature", "implement payment", "create dashboard"
-   - Missing: How, with what technology, what constraints?
-
-2. **Missing Technical Context**
-   - No technology stack mentioned
-   - No integration points identified
-   - No performance/security constraints
-
-3. **Incomplete Specifications**
-   - No acceptance criteria
-   - No success metrics
-   - No edge cases considered
-   - No error handling mentioned
-
-4. **Ambiguous Scope**
-   - Unclear boundaries ("user management" - what exactly?)
-   - No distinction between MVP and future enhancements
-   - Missing "what's NOT included"
-
-**Do NOT activate when**:
-- Specific file paths mentioned (e.g., "auth.go:45")
-- Code snippets included
-- Existing functions/classes referenced
-- Bug fixes with clear reproduction steps
-
-## Core Principles
-
-1. **Systematic Questioning**
-   - Ask focused, specific questions
-   - One category at a time (2-3 questions per round)
-   - Build on previous answers
-   - Avoid overwhelming users
-
-2. **Quality-Driven Iteration**
-   - Continuously assess clarity score (0-100)
-   - Identify gaps systematically
-   - Iterate until ≥ 90 points
-   - Document all clarification rounds
-
-3. **Actionable Output**
-   - Generate concrete specifications
-   - Include measurable acceptance criteria
-   - Provide executable phases
-   - Enable direct implementation
-
-## Clarification Process
-
-### Step 1: Initial Requirement Analysis
-
-**Input**: User's requirement description
-
-**Tasks**:
-1. Parse and understand core requirement
-2. Generate feature name (kebab-case format)
-3. Determine document version (default `1.0` unless user specifies otherwise)
-4. Ensure `./docs/prds/` exists for PRD output
-5. Perform initial clarity assessment (0-100)
-
-**Assessment Rubric**:
-```
-Functional Clarity: /30 points
-- Clear inputs/outputs: 10 pts
-- User interaction defined: 10 pts
-- Success criteria stated: 10 pts
-
-Technical Specificity: /25 points
-- Technology stack mentioned: 8 pts
-- Integration points identified: 8 pts
-- Constraints specified: 9 pts
-
-Implementation Completeness: /25 points
-- Edge cases considered: 8 pts
-- Error handling mentioned: 9 pts
-- Data validation specified: 8 pts
-
-Business Context: /20 points
-- Problem statement clear: 7 pts
-- Target users identified: 7 pts
-- Success metrics defined: 6 pts
-```
-
-**Initial Response Format**:
-```markdown
-I understand your requirement. Let me help you refine this specification.
-
-**Current Clarity Score**: X/100
-
-**Clear Aspects**:
-- [List what's clear]
-
-**Needs Clarification**:
-- [List gaps]
-
-Let me systematically clarify these points...
-```
-
-### Step 2: Gap Analysis
-
-Identify missing information across four dimensions:
-
-**1. Functional Scope**
-- What is the core functionality?
-- What are the boundaries?
-- What is out of scope?
-- What are edge cases?
-
-**2. User Interaction**
-- How do users interact?
-- What are the inputs?
-- What are the outputs?
-- What are success/failure scenarios?
-
-**3. Technical Constraints**
-- Performance requirements?
-- Compatibility requirements?
-- Security considerations?
-- Scalability needs?
-
-**4. Business Value**
-- What problem does this solve?
-- Who are the target users?
-- What are success metrics?
-- What is the priority?
-
-### Step 3: Interactive Clarification
-
-**Question Strategy**:
-1. Start with highest-impact gaps
-2. Ask 2-3 questions per round
-3. Build context progressively
-4. Use user's language
-5. Provide examples when helpful
-
-**Question Format**:
-```markdown
-I need to clarify the following points to complete the requirements document:
-
-1. **[Category]**: [Specific question]?
-   - For example: [Example if helpful]
-
-2. **[Category]**: [Specific question]?
-
-3. **[Category]**: [Specific question]?
-
-Please provide your answers, and I'll continue refining the PRD.
-```
-
-**After Each User Response**:
-1. Update clarity score
-2. Capture new information in the working PRD outline
-3. Identify remaining gaps
-4. If score < 90: Continue with next round of questions
-5. If score ≥ 90: Proceed to PRD generation
-
-**Score Update Format**:
-```markdown
-Thank you for the additional information!
-
-**Clarity Score Update**: X/100 → Y/100
-
-**New Clarified Content**:
-- [Summarize new information]
-
-**Remaining Points to Clarify**:
-- [List remaining gaps if score < 90]
-
-[If score < 90: Continue with next round of questions]
-[If score ≥ 90: "Perfect! I will now generate the complete PRD document..."]
-```
-
-### Step 4: PRD Generation
-
-Once clarity score ≥ 90, generate comprehensive PRD.
-
-**Output File**:
-
-1. **Final PRD**: `./docs/prds/{feature_name}-v{version}-prd.md`
-
-Use the `Write` tool to create or update this file. Derive `{version}` from the document version recorded in the PRD (default `1.0`).
-
