Subject: [PATCH] feat(workflow): add project-level state management with
 intelligent initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement comprehensive project.json system for tracking project state, completed features, and architecture overview.

## New Features

### 1. /workflow:init Command (NEW)
- Independent project initialization command using cli-explore-agent
- Deep Scan mode analyzes: technology stack, architecture, key components, metrics
- Generates project.json with comprehensive overview field
- Supports --regenerate flag to update analysis while preserving features
- One-time initialization with intelligent project cognition

### 2. Enhanced session:start
- Added Step 0: Check project.json existence before session creation
- Auto-calls /workflow:init if project.json missing
- Separated project-level vs session-level initialization responsibilities

### 3. Enhanced session:complete
- Added Phase 3: Update Project Feature Registry
- Extracts feature metadata from IMPL_PLAN.md
- Records completed sessions as features in project.json
- Includes: title, description, tags, timeline, traceability (archive_path, commit_hash)
- Auto-generates feature IDs and tags from implementation plans

### 4. Enhanced status Command
- Added --project flag for project overview mode
- Displays: technology stack, architecture patterns, key components, metrics
- Shows completed features with full traceability
- Provides query commands for feature exploration

### 5. Enhanced context-gather
- Integrated project.json reading in context-search-agent workflow
- Phase 1: Load project.json overview as foundational context
- Phase 3: Populate context-package.json from project.json
- Prioritizes project.json context for architecture and tech stack
- Avoids redundant project analysis on every planning session

## Data Flow
project.json (init) → context-gather → context-package.json → task-generation
session-complete → project.json (features registry)

## Benefits
- Single source of truth for project state
- Efficient context reuse across sessions
- Complete feature traceability and history
- Consistent architectural baseline for all workflows

+
+# Workflow Init Command (/workflow:init)
+
+## Overview
+Initializes `.workflow/project.json` with comprehensive project understanding by leveraging **cli-explore-agent** for intelligent analysis.
+
+**Key Features**:
+- **Intelligent Project Analysis**: Uses cli-explore-agent's Deep Scan mode
+- **Technology Stack Detection**: Identifies languages, frameworks, build tools
+- **Architecture Overview**: Discovers patterns, layers, key components
+- **One-time Initialization**: Skips if project.json exists (unless --regenerate)
+
+## Usage
+```bash
+/workflow:init                 # Initialize project state (skip if exists)
+/workflow:init --regenerate    # Force regeneration of project.json
+```
+
+## Implementation Flow
+
+### Step 1: Check Existing State
+
+```bash
+# Check if project.json already exists
+bash(test -f .workflow/project.json && echo "EXISTS" || echo "NOT_FOUND")
+```
+
+**If EXISTS and no --regenerate flag**:
+```
+Project already initialized at .workflow/project.json
+Use /workflow:init --regenerate to rebuild project analysis
+Use /workflow:status --project to view current state
+```
+
+**If NOT_FOUND or --regenerate flag**: Proceed to initialization
+
+### Step 2: Project Discovery
+
+```bash
+# Get project name and root
+bash(basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
+bash(git rev-parse --show-toplevel 2>/dev/null || pwd)
+
+# Create .workflow directory
+bash(mkdir -p .workflow)
+```
+
+### Step 3: Intelligent Project Analysis
+
+**Invoke cli-explore-agent** with Deep Scan mode for comprehensive understanding:
+
+```javascript
+Task(
+  subagent_type="cli-explore-agent",
+  description="Deep project analysis",
+  prompt=`
+Analyze project structure and technology stack for workflow initialization.
+
+## Analysis Objective
+Perform Deep Scan analysis to build comprehensive project understanding for .workflow/project.json initialization.
+
+## Required Analysis
+
+### 1. Technology Stack Detection
+- **Primary Languages**: Identify all programming languages with file counts
+- **Frameworks**: Detect web frameworks (React, Vue, Express, Django, etc.)
+- **Build Tools**: Identify build systems (npm, cargo, maven, gradle, etc.)
+- **Test Frameworks**: Find testing tools (jest, pytest, go test, etc.)
+
+### 2. Project Architecture
+- **Architecture Style**: Identify patterns (MVC, microservices, monorepo, etc.)
+- **Layer Structure**: Discover architectural layers (presentation, business, data)
+- **Design Patterns**: Find common patterns (singleton, factory, repository, etc.)
+- **Key Components**: List 5-10 core modules/components with brief descriptions
+
+### 3. Project Metrics
+- **Total Files**: Count source code files
+- **Lines of Code**: Estimate total LOC
+- **Module Count**: Number of top-level modules/packages
+- **Complexity**: Overall complexity rating (low/medium/high)
+
+### 4. Entry Points
+- **Main Entry**: Identify primary application entry point(s)
+- **CLI Commands**: Discover available commands/scripts
+- **API Endpoints**: Find HTTP/REST/GraphQL endpoints (if applicable)
+
+## Execution Mode
+Use **Deep Scan** with Dual-Source Strategy:
+- Phase 1: Bash structural scan (fast pattern discovery)
+- Phase 2: Gemini semantic analysis (design intent, patterns)
+- Phase 3: Synthesis (merge findings with attribution)
+
+## Analysis Scope
+- Root directory: ${projectRoot}
+- Exclude: node_modules, dist, build, .git, vendor, __pycache__
+- Focus: Source code directories (src, lib, pkg, app, etc.)
+
+## Output Format
+Return JSON structure for programmatic processing:

+
+// Helper: Generate project description
+function generateDescription(analysis) {

+
+## Regeneration Behavior
+
+When using `--regenerate` flag:
+
+1. **Backup existing file**:
+   ```bash
+   bash(cp .workflow/project.json .workflow/project.json.backup)
+   ```
+
+2. **Preserve features array**:
+   ```javascript
+   const existingMeta = JSON.parse(Read('.workflow/project.json'));
+   const preservedFeatures = existingMeta.features || [];
+   const preservedStats = existingMeta.statistics || {};
+   ```
+
+3. **Re-run cli-explore-agent analysis**
+
+4. **Merge preserved data with new analysis**:
+   ```javascript
+   const newProjectMeta = {
+     ...analysisResults,
+     features: preservedFeatures,        // Keep existing features
+     statistics: preservedStats          // Keep statistics
+   };
+   ```
+
+5. **Output**:
+   ```
+   ✓ Project analysis regenerated
+   Backup saved: .workflow/project.json.backup
+
+   Updated:
+   - Technology stack analysis
+   - Architecture overview
+   - Key components discovery
+
+   Preserved:
+   - ${preservedFeatures.length} existing features
+   - Session statistics
+   ```
+
+## Error Handling
+
+### Agent Failure
+```
+If cli-explore-agent fails:
+1. Fall back to basic initialization
+2. Use get_modules_by_depth.sh for structure
+3. Create minimal project.json with placeholder overview
+4. Log warning: "Project initialized with basic analysis. Run /workflow:init --regenerate for full analysis"
+```
+
+### Missing Tools
+```
+If Gemini CLI unavailable:
+1. Agent uses Qwen fallback
+2. If both fail, use bash-only analysis
+3. Mark in _metadata: "analysis_mode": "bash-fallback"
+```
+
+### Invalid Project Root
+```
+If not in git repo and empty directory:
+1. Warn user: "Empty project detected"
+2. Create minimal project.json
+3. Suggest: "Add code files and run /workflow:init --regenerate"
+```
+
+## Integration with Existing Commands
+
+### /workflow:session:start
+Modified to check and call init:
+```javascript
+// In start.md Step 0
+if (!FileExists('.workflow/project.json')) {
+  console.log("Project not initialized. Running /workflow:init...");
+  SlashCommand({command: "/workflow:init"});
+  // Wait for completion, then continue with session creation
+}
+```
+
+### /workflow:status --project
+Uses extended overview fields:
+```javascript
+console.log(`## Technology Stack`);
+console.log(`Languages: ${overview.technology_stack.languages.map(l => l.name).join(', ')}`);
+console.log(`Frameworks: ${overview.technology_stack.frameworks.join(', ')}`);
+
+console.log(`\n## Architecture`);
+console.log(`Style: ${overview.architecture.style}`);
+console.log(`Patterns: ${overview.architecture.patterns.join(', ')}`);
+
+console.log(`\n## Key Components (${overview.key_components.length})`);
+overview.key_components.forEach(c => {
+  console.log(`- ${c.name} (${c.path})`);
+  console.log(`  ${c.description}`);
+});
+```
+
+## Performance Considerations
+
+**Execution Time**:
+- cli-explore-agent Deep Scan: 2-5 minutes
+- Total initialization: 2-6 minutes (one-time cost)
+
+**Optimization**:
+- Skip regeneration if project.json exists
+- Cache analysis results in _metadata
+- Parallel execution: project discovery + agent analysis
+
+## Related Commands
+- `/workflow:session:start` - Calls init if needed
+- `/workflow:status --project` - Views project overview
+- `/workflow:init --regenerate` - Updates project analysis

+### Phase 3: Update Project Feature Registry
+
+**Purpose**: Record completed session as a project feature in `.workflow/project.json`.
+
+**Execution**: After agent successfully completes archival, extract feature information and update project registry.
+
+#### Step 3.1: Check Project State Exists
+```bash
+bash(test -f .workflow/project.json && echo "EXISTS" || echo "SKIP")
+```
+
+**If SKIP**: Output warning and skip Phase 3
+```
+WARNING: No project.json found. Run /workflow:session:start to initialize.
+```
+
+#### Step 3.2: Extract Feature Information (Simple Text Processing)
+
+```bash
+# Read archived IMPL_PLAN.md
+bash(cat .workflow/.archives/WFS-session-name/IMPL_PLAN.md | head -20)
+```
+
+**Data Processing** (No agent needed):
+1. Extract feature title: First `#` heading line
+2. Extract description: First paragraph after heading (max 200 chars)
+3. Get session_id from archive path
+4. Get completion timestamp
+
+**Extraction Logic**:
+```javascript
+// Read IMPL_PLAN.md
+const planContent = Read(`${archivePath}/IMPL_PLAN.md`);
+
+// Extract title (first # heading)
+const titleMatch = planContent.match(/^#\s+(.+)$/m);
+const title = titleMatch ? titleMatch[1].trim() : sessionId.replace('WFS-', '');
+
+// Extract description (first paragraph, max 200 chars)
+const descMatch = planContent.match(/^#[^\n]+\n\n([^\n]+)/m);
+const description = descMatch ? descMatch[1].substring(0, 200).trim() : '';
+
+// Create feature ID (lowercase slug)
+const featureId = title.toLowerCase().replace(/[^a-z0-9]+/g, '-').substring(0, 50);
+```
+
+#### Step 3.3: Update project.json
+
+```bash
+# Read current project state
+bash(cat .workflow/project.json)
+```
+
+**JSON Update Logic**:
+```javascript
+// Read existing project.json (created by /workflow:init)
+// Note: overview field is managed by /workflow:init, not modified here
+const projectMeta = JSON.parse(Read('.workflow/project.json'));
+const currentTimestamp = new Date().toISOString();
+const currentDate = currentTimestamp.split('T')[0]; // YYYY-MM-DD
+
+// Extract tags from IMPL_PLAN.md (simple keyword extraction)
+const tags = extractTags(planContent); // e.g., ["auth", "security"]
+
+// Build feature object with complete metadata
+const newFeature = {
+  id: featureId,
+  title: title,
+  description: description,
+  status: "completed",
+  tags: tags,
+  timeline: {
+    created_at: currentTimestamp,
+    implemented_at: currentDate,
+    updated_at: currentTimestamp
+  },
+  traceability: {
+    session_id: sessionId,
+    archive_path: archivePath, // e.g., ".workflow/.archives/WFS-auth-system"
+    commit_hash: getLatestCommitHash() || "" // Optional: git rev-parse HEAD
+  },
+  docs: [],      // Placeholder for future doc links
+  relations: []  // Placeholder for feature dependencies
+};
+
+// Add new feature to array
+projectMeta.features.push(newFeature);
+
+// Update statistics
+projectMeta.statistics.total_features = projectMeta.features.length;
+projectMeta.statistics.total_sessions += 1;
+projectMeta.statistics.last_updated = currentTimestamp;
+
+// Write back
+Write('.workflow/project.json', JSON.stringify(projectMeta, null, 2));
+```
+
+**Helper Functions**:
+```javascript
+// Extract tags from IMPL_PLAN.md content
+function extractTags(planContent) {
+  const tags = [];
+
+  // Look for common keywords
+  const keywords = {
+    'auth': /authentication|login|oauth|jwt/i,
+    'security': /security|encrypt|hash|token/i,
+    'api': /api|endpoint|rest|graphql/i,
+    'ui': /component|page|interface|frontend/i,
+    'database': /database|schema|migration|sql/i,
+    'test': /test|testing|spec|coverage/i
+  };
+
+  for (const [tag, pattern] of Object.entries(keywords)) {
+    if (pattern.test(planContent)) {
+      tags.push(tag);
+    }
+  }
+
+  return tags.slice(0, 5); // Max 5 tags
+}
+
+// Get latest git commit hash (optional)
+function getLatestCommitHash() {
+  try {
+    const result = Bash({
+      command: "git rev-parse --short HEAD 2>/dev/null",
+      description: "Get latest commit hash"
+    });
+    return result.trim();
+  } catch {
+    return "";
+  }
+}
+```
+
+#### Step 3.4: Output Confirmation
+
+```
+✓ Feature "${title}" added to project registry
+  ID: ${featureId}
+  Session: ${sessionId}
+  Location: .workflow/project.json
+```
+
+**Error Handling**:
+- If project.json malformed: Output error, skip update
+- If IMPL_PLAN.md missing: Use session_id as title
+- If extraction fails: Use minimal defaults
+
+**Phase 3 Total Commands**: 2 bash reads + JSON manipulation

 ## Overview
 Manages workflow sessions with three operation modes: discovery (manual), auto (intelligent), and force-new.
 
+**Dual Responsibility**:
+1. **Project-level initialization** (first-time only): Creates `.workflow/project.json` for feature registry
+2. **Session-level initialization** (always): Creates session directory structure
+
+## Step 0: Initialize Project State (First-time Only)
+
+**Executed before all modes** - Ensures project-level state file exists by calling `/workflow:init`.
+
+### Check and Initialize
+```bash
+# Check if project state exists
+bash(test -f .workflow/project.json && echo "EXISTS" || echo "NOT_FOUND")
+```
+
+**If NOT_FOUND**, delegate to `/workflow:init`:
+```javascript
+// Call workflow:init for intelligent project analysis
+SlashCommand({command: "/workflow:init"});
+
+// Wait for init completion
+// project.json will be created with comprehensive project overview
+```
+
+**Output**:
+- If EXISTS: `PROJECT_STATE: initialized`
+- If NOT_FOUND: Calls `/workflow:init` → creates `.workflow/project.json` with full project analysis
+
+**Note**: `/workflow:init` uses cli-explore-agent to build comprehensive project understanding (technology stack, architecture, key components). This step runs once per project. Subsequent executions skip initialization.

 # Workflow Status Command (/workflow:status)
 
 ## Overview
-Generates on-demand views from JSON task data. No synchronization needed - all views are calculated from the current state of JSON files.
+Generates on-demand views from project and session data. Supports two modes:
+1. **Project Overview** (`--project`): Shows completed features and project statistics
+2. **Workflow Tasks** (default): Shows current session task progress
+
+No synchronization needed - all views are calculated from current JSON state.
 
 ## Usage
 ```bash
-/workflow:status                    # Show current workflow overview
+/workflow:status                    # Show current workflow session overview
+/workflow:status --project          # Show project-level feature registry
 /workflow:status impl-1             # Show specific task details
 /workflow:status --validate         # Validate workflow integrity
 ```
 
 ## Implementation Flow
 
+### Mode Selection
+
+**Check for --project flag**:
+- If `--project` flag present → Execute **Project Overview Mode**
+- Otherwise → Execute **Workflow Session Mode** (default)
+
+## Project Overview Mode
+
+### Step 1: Check Project State
+```bash
+bash(test -f .workflow/project.json && echo "EXISTS" || echo "NOT_FOUND")
+```
+
+**If NOT_FOUND**:
+```
+No project state found.
+Run /workflow:session:start to initialize project.
+```
+
+### Step 2: Read Project Data
+```bash
+bash(cat .workflow/project.json)
+```
+
+### Step 3: Parse and Display
+
+**Data Processing**:
+```javascript
+const projectData = JSON.parse(Read('.workflow/project.json'));
+const features = projectData.features || [];
+const stats = projectData.statistics || {};
+const overview = projectData.overview || null;
+
+// Sort features by implementation date (newest first)
+const sortedFeatures = features.sort((a, b) =>
+  new Date(b.implemented_at) - new Date(a.implemented_at)
+);
+```
+
+**Output Format** (with extended overview):
+```

 ## Notes
 
 - **Detection-first**: Always check for existing package before invoking agent
+- **Project.json integration**: Agent reads `.workflow/project.json` as primary source for project context, avoiding redundant analysis
 - **Agent autonomy**: Agent handles all discovery logic per `.claude/agents/context-search-agent.md`
 - **No redundancy**: This command is a thin orchestrator, all logic in agent
 - **Plan-specific**: Use this for implementation planning; brainstorm mode uses direct agent call
