-# Unified Context Command (/context)
+# Context Command (/context)
 
 ## Overview
+Generates on-demand views from JSON task data. No synchronization needed - all views are calculated from the current state of JSON files.
 
-**Single Source of Truth**: This command replaces `/workflow:context` and `/task:context` with a unified interface that generates all views on-demand from JSON data. Eliminates synchronization complexity by making documents read-only views.
+## Core Principles
+**Data Source:** @~/.claude/workflows/json-document-coordination-system.md  
+**Session Management:** @~/.claude/workflows/session-management-principles.md
 
-## Core Architecture
+## Key Features
 
-### Single Source of Truth Principle
-- **JSON Authority**: All data read from `.task/*.json` and `workflow-session.json` files
-- **Generated Views**: All markdown displays generated on-demand (never manually edited)
-- **No Synchronization**: Documents are views, not synchronized states
-- **Conflict-Free**: Single direction data flow eliminates conflicts
+### Pure View Generation
+- **No Sync**: Views are generated, not synchronized
+- **Always Current**: Reads latest JSON data every time
+- **No Persistence**: Views are temporary, not saved
+- **Single Source**: All data comes from JSON files only
 
-### Unified Command Interface
-- **Global Context**: `/context` shows complete workflow status
-- **Task-Specific**: `/context IMPL-001` shows individual task details  
-- **Health Checking**: `/context --health-check` validates JSON data integrity
-- **Multiple Formats**: Tree, list, progress, and JSON output formats
+### Multiple View Formats
+- **Overview** (default): Current tasks and status
+- **Hierarchy**: Task relationships and structure
+- **Details**: Specific task information

-### Data Management
-- All commands now work with JSON as single source of truth
-- Document generation happens on-demand
-- No synchronization commands needed
-- Simplified data model improves reliability
+## View Generation Process
 
+### Data Loading
+```pseudo
+function generate_context_view(task_id, format):
+  // Load all current data
+  session = load_workflow_session()
+  all_tasks = load_all_task_json_files()
+  
+  // Filter if specific task requested
+  if task_id:
+    target_task = find_task(all_tasks, task_id)
+    return generate_task_detail_view(target_task)
+  
+  // Generate requested format
+  switch format:
+    case 'hierarchy':
+      return generate_hierarchy_view(all_tasks)
+    default:
+      return generate_overview(session, all_tasks)
+```
+
+### Real-Time Calculation
+- **Task Counts**: Calculated from JSON file status fields
+- **Relationships**: Built from JSON relations fields
+- **Status**: Read directly from current JSON state
+
+## Validation Mode
+
+### Basic Validation
+```bash
+/context --validate
+```
+
+Performs integrity checks:
+```markdown
+# Validation Results
+
+## JSON File Validation
+✅ All task JSON files are valid
+✅ Session file is valid and readable
+
+## Relationship Validation  
+✅ All parent-child relationships are valid
+✅ All dependencies reference existing tasks
+✅ No circular dependencies detected
+
+## Hierarchy Validation
+✅ Task hierarchy within depth limits (max 3 levels)
+✅ All subtask references are bidirectional
+
+## Issues Found
+⚠️ impl-3: No subtasks defined (expected for leaf task)
+
+**Status**: All systems operational
+```
+
+### Validation Checks
+- **JSON Schema**: All files parse correctly
+- **References**: All task IDs exist
+- **Hierarchy**: Parent-child relationships are valid
+- **Dependencies**: No circular dependencies
+- **Depth**: Task hierarchy within limits
+
+## Error Handling
+
+### Missing Files
+```bash
+❌ Session file not found
+→ Initialize new workflow session? (y/n)
+
+❌ Task impl-5 not found  
+→ Available tasks: impl-1, impl-2, impl-3, impl-4
+```
+
+### Invalid Data
+```bash
+❌ Invalid JSON in impl-2.json
+→ Cannot generate view for impl-2
+→ Repair file manually or recreate task
+
+⚠️ Circular dependency detected: impl-1 → impl-2 → impl-1
+→ Task relationships may be incorrect
+```
+
+## Performance Benefits
+
+### Fast Generation
+- **No File Writes**: Only reads JSON files
+- **No Sync Logic**: No complex synchronization
+- **Instant Results**: Generate views on demand
+- **No Conflicts**: No state consistency issues
+
+### Scalability
+- **Large Task Sets**: Handles hundreds of tasks efficiently
+- **Complex Hierarchies**: No performance degradation
+- **Concurrent Access**: Multiple views can be generated simultaneously
+
+## Integration
+
+### Workflow Integration
+- Use after task creation to see current state
+- Use for debugging task relationships
+
+### Command Integration
+```bash
+# Common workflow
+/task:create "New feature"
+/context                    # Check current state
+/task:breakdown impl-1  
+/context --format=hierarchy # View new structure
+/task:execute impl-1.1
+```
+
+## Output Formats
+
+### Supported Formats
+- `overview` (default): General workflow status
+- `hierarchy`: Task relationships
+- `tasks`: Simple task list
+- `details`: Comprehensive information
+
+### Custom Filtering
+```bash
+# Show only active tasks
+/context --format=tasks --filter=active
+
+# Show completed tasks only
+/context --format=tasks --filter=completed
+
+# Show tasks for specific agent
+/context --format=tasks --agent=code-developer
+```
+
+## Related Commands
+
+- `/task:create` - Create tasks (generates JSON data)
+- `/task:execute` - Execute tasks (updates JSON data)
+- `/task:breakdown` - Create subtasks (generates more JSON data)  
+- `/workflow:vibe` - Coordinate agents (uses context for coordination)
+
+This context system provides instant, accurate views of workflow state without any synchronization complexity or performance overhead.

-### Built-in Document Creation Process
-
-#### Level 0: Unified Document Updates (<15 tasks)
-When task count is below threshold, command automatically updates unified documents:
-- Updates existing IMPL_PLAN.md with enhanced task hierarchy structure
-- Updates existing TODO_LIST.md with progress tracking
-- Maintains TODO_LIST.md for progress coordination
-
-#### Level 1: Task-Based Document Generation (15-50 tasks)
-When enhanced complexity detected, command automatically:
-
-**Updates IMPL_PLAN.md with task breakdown**:
-- Adds hierarchical task structure with subtasks
-- Updates requirements and acceptance criteria
-- Maintains cross-references to JSON task files
-- Preserves overall workflow context
-
-**Creates/Updates TODO_LIST.md**:
-- Displays hierarchical task structure with checkboxes
-- Shows progress percentages and completion status
-- Cross-references task details with JSON files
-- Provides at-a-glance workflow progress overview
-
-#### Level 2: Complete Structure Document Updates (>15 tasks)
-When complex workflows detected, command automatically:
-
-**Expands IMPL_PLAN.md with comprehensive planning**:
-- Detailed task hierarchy with up to 3 levels deep
-- Complete requirements analysis and acceptance criteria
-- Risk assessment and mitigation strategies
-- Cross-references to all JSON task files
-
-**Maintains comprehensive TODO_LIST.md**:
-- Full hierarchical display with progress rollups
-- Multi-level task completion tracking
-- Detailed progress percentages across task hierarchy
-- Cross-references to .summaries/ for completed tasks
-
-**Manages .summaries/ directory**:
-- Creates task completion documentation structure
-- Maintains audit trail of implementation decisions
-- Links completed tasks back to workflow session
-
-### JSON Task Management Integration

-    "splitting_level": 2
-  }
-}
-```
-
-#### TODO_LIST.md Integration
-The task breakdown automatically updates TODO_LIST.md with:
-
-- **Hierarchical Task Display**: Shows parent-child relationships using checkbox indentation
-- **Progress Tracking**: Calculates completion percentages based on subtask status
-- **JSON Cross-References**: Links to .task/ JSON files for detailed task information
-- **Status Synchronization**: Keeps TODO_LIST.md checkboxes in sync with JSON task status
-
-### Coordination with IMPL_PLAN.md
-
-If IMPL_PLAN.md exists (complex workflows), task breakdown validates against phase structure:
-
-```markdown
-### Phase 1: Foundation
-- **Tasks**: IMPL-1 → Now broken down to IMPL-1.1-4
-- **Validation**: ✅ All subtasks align with phase objectives
-- **Dependencies**: ✅ Phase dependencies preserved
-```
-
-## Advanced Options
-
-### Depth Control
-```bash
-# Single level (default)
-/task:breakdown IMPL-1 --depth=1
-
-# Two levels (for complex tasks)
-/task:breakdown IMPL-1 --depth=2
-```
-
-### Custom Breakdown
-```bash
-/task:breakdown IMPL-1 --custom
-> Enter subtask 1: Custom subtask title
-> Assign agent (auto/manual): auto
-> Enter subtask 2: ...
-```
-
-## Task Validation & Error Handling
-
-### Comprehensive Validation Checks
-```bash
-/task:breakdown impl-1 --validate
-
-Pre-breakdown validation:
-✅ workflow-session.json exists and is writable
-✅ .task/ directory accessible
-✅ Parent task JSON file valid
-✅ Hierarchy depth within limits (max 3 levels)
-⚠️ Complexity threshold reached - will generate TODO_LIST.md
-
-Post-breakdown validation:
-✅ All subtask JSON files created in .task/
-✅ Parent-child relationships established
-✅ Cross-references consistent across files
-✅ TODO_LIST.md generated/updated (if triggered)
-✅ workflow-session.json synchronized
-✅ File structure matches complexity level
-```
-
-### Error Recovery & File Management
-```bash
-# JSON file conflicts
-⚠️ Parent task JSON structure inconsistent with breakdown
-→ Auto-sync parent JSON file? (y/n)
-
-# Missing directory structure  
-❌ .task/ directory not found
-→ Create required directory structure? (y/n)
-
-# Complexity level mismatch
-⚠️ Task count suggests Level 1 but structure is Level 0
-→ 1. Upgrade structure  2. Keep minimal  3. Manual adjustment
-
-# Hierarchy depth violation
-❌ Attempting to create impl-1.2.3.4 (exceeds 3-level limit)
-→ 1. Flatten hierarchy  2. Reorganize structure  3. Abort
-```
-
-## Integration

-## Dynamic Complexity Escalation (NEW FEATURE)
-
-### Automatic Workflow Upgrade System
-After each task creation, the system automatically evaluates current workflow complexity and upgrades structure when thresholds are exceeded.
-
-### Escalation Process
-```
-1. Create New Task → Generate JSON file
-2. Count All Tasks → Read all .task/*.json files  
-3. Calculate Metrics → Tasks, modules, dependencies, effort
-4. Check Thresholds → Compare against complexity criteria
-5. Trigger Upgrade → If threshold exceeded, escalate complexity
-6. Generate Documents → Auto-create missing structure documents
-7. Update Session → Record complexity change in workflow-session.json
-8. Notify User → Inform about automatic upgrade
+1. Create New Task → Generate JSON file only
+2. Update Session Stats → Increment task count  
+3. Notify User → Confirm task created
 ```
 
-### Escalation Triggers
-
-#### Simple → Medium Escalation
-**Triggered when ANY condition met:**
-- Task count reaches 5 (primary trigger)
-- Module count exceeds 3 
-- Total estimated effort > 4 hours
-- Complex dependencies detected
-- Cross-component changes required
-
-**Actions taken:**
-```bash
-✅ Task created: impl-5
-⚠️ Complexity threshold reached: 5 tasks (exceeds Simple limit)
-🔄 Escalating workflow: Simple → Medium
-
-Auto-generating enhanced structure:
-✅ Created TODO_LIST.md with hierarchical task display
-✅ Created .summaries/ directory for task completion tracking  
-✅ Updated workflow-session.json complexity level
-✅ Enabled 2-level task hierarchy (impl-N.M)
-
-Workflow now supports:
-- Progress tracking via TODO_LIST.md
-- Task decomposition up to 2 levels
-- Summary generation for completed tasks
-```
-
-#### Medium → Complex Escalation  
-**Triggered when ANY condition met:**
-- Task count reaches 15 (primary trigger)
-- Module count exceeds 5
-- Total estimated effort > 2 days
-- Multi-repository impacts detected
-- Architecture pattern changes required
-
-**Actions taken:**
-```bash
-✅ Task created: impl-15
-⚠️ Complexity threshold reached: 15 tasks (exceeds Medium limit)  
-🔄 Escalating workflow: Medium → Complex
-
-Auto-generating comprehensive structure:
-✅ Enhanced IMPL_PLAN.md with detailed phases and risk assessment
-✅ Expanded TODO_LIST.md with progress monitoring
-✅ Created comprehensive .summaries/ structure
-✅ Updated workflow-session.json complexity level
-✅ Enabled 3-level task hierarchy (impl-N.M.P maximum)
-
-Workflow now supports:
-- Comprehensive progress tracking and monitoring
-- Full 3-level task decomposition
-- Enhanced documentation and audit trails
-- Advanced dependency management
-```
-
-### Complexity Calculation Algorithm
-```javascript
-function calculateComplexity(tasks, modules, effort, dependencies) {
-  // Primary thresholds (hard limits)
-  if (tasks >= 15 || modules > 5 || effort > 48) return 'complex';
-  if (tasks >= 5 || modules > 3 || effort > 4) return 'medium';
-  
-  // Override factors (can force higher complexity)
-  if (dependencies.includes('multi-repo') || 
-      dependencies.includes('architecture-change')) return 'complex';
-  if (dependencies.includes('cross-component') ||
-      dependencies.includes('complex-integration')) return 'medium';
-      
-  return 'simple';

-### Benefits of Dynamic Escalation
-- **Seamless Growth**: Workflows grow naturally without user intervention
-- **No Overhead for Simple Tasks**: Simple workflows remain minimal
-- **Automatic Structure**: Enhanced documentation appears when needed
-- **Progressive Enhancement**: Users get appropriate tooling for current complexity
-- **Transparent Process**: All escalations logged and reversible
+### Benefits of Simplification
+- **No Overhead**: Just create tasks, no complex logic
+- **Predictable**: Same process every time
+- **Fast**: Minimal processing needed
+- **Clear**: User controls complexity level
 
 ## Context Inheritance
 
 Tasks automatically inherit:
-1. **Requirements** - From workflow-session.json context and IMPL_PLAN.md
-2. **Scope** - File patterns from workflow and IMPL_PLAN.md strategy
-3. **Standards** - Quality standards from workflow session
-4. **Dependencies** - Related tasks from existing JSON task hierarchy in `.task/`
-5. **Parent Context** - When created as subtasks, inherit from parent JSON file
-6. **Session Context** - Global workflow context from active session

 # Task Replan Command (/task:replan)
 
 ## Overview
-Dynamically adjusts task planning based on changes, new requirements, blockers, or execution results.
+Replans individual tasks based on detailed user input with comprehensive change tracking, version management, and document synchronization. Focuses exclusively on single-task modifications with rich input options.
 
 ## Core Principles
-**System Architecture:** @~/.claude/workflows/unified-workflow-system-principles.md  
+**System:** @~/.claude/workflows/unified-workflow-system-principles.md
+**Task Management:** @~/.claude/workflows/task-management-principles.md
 
+## Single-Task Focus
+This command operates on **individual tasks only**. For workflow-wide changes, use `/workflow:action-plan` instead.
 
-## Replan Triggers
+⚠️ **CRITICAL**: Before replanning, checks for existing active session to avoid conflicts.
 
-⚠️ **CRITICAL**: Before replanning, MUST check for existing active session to avoid creating duplicate sessions.
+## Input Sources for Replanning
 
-### Session Check Process
-1. **Query Session Registry**: Check `.workflow/session_status.jsonl` for active sessions. If the file doesn't exist, create it.
-2. **Session Validation**: Use existing active session containing the task to be replanned
-3. **Context Integration**: Load existing session state and task hierarchy
-
-### Automatic Detection
-System detects replanning needs from file monitoring:
-- Requirements changed in workflow-session.json
-- Dependencies blocked in JSON task hierarchy  
-- Task failed execution (logged in JSON execution history)
-- New issues discovered and associated with tasks
-- Scope modified in task context or IMPL_PLAN.md
-- File structure complexity changes requiring reorganization
-
-### Manual Triggers
+### Direct Text Input (Default)
 ```bash
-/task:replan IMPL-001 --reason="API spec updated"
+/task:replan impl-1 "Add OAuth2 authentication support"
+```
+**Processing**:
+- Parse specific changes and requirements
+- Extract new features or modifications needed
+- Apply directly to target task structure
+
+### File-based Requirements
+```bash
+/task:replan impl-1 --from-file updated-specs.md
+/task:replan impl-1 --from-file requirements-change.txt
+```
+**Supported formats**: .md, .txt, .json, .yaml
+**Processing**:
+- Read detailed requirement changes from file
+- Parse structured specifications and updates
+- Apply file content to task replanning
+
+### Issue-based Replanning
+```bash
+/task:replan impl-1 --from-issue ISS-001
+/task:replan impl-1 --from-issue "bug-report"
+```
+**Processing**:
+- Load issue description and requirements
+- Extract necessary changes for task
+- Apply issue resolution to task structure
+
+### Detailed Mode
+```bash
+/task:replan impl-1 --detailed
+```
+**Guided Input**:
+1. **New Requirements**: What needs to be added/changed?
+2. **Scope Changes**: Expand/reduce task scope?
+3. **Subtask Modifications**: Add/remove/modify subtasks?
+4. **Dependencies**: Update task relationships?
+5. **Success Criteria**: Modify completion conditions?
+6. **Agent Assignment**: Change assigned agent?
+
+### Interactive Mode
+```bash
+/task:replan impl-1 --interactive
+```
+**Step-by-Step Process**:
+1. **Current Analysis**: Review existing task structure
+2. **Change Identification**: What needs modification?
+3. **Impact Assessment**: How changes affect task?
+4. **Structure Updates**: Add/modify subtasks
+5. **Validation**: Confirm changes before applying
+
+## Replanning Flow with Change Tracking
+
+### 1. Task Loading & Validation
+```
+Load Task → Read current task JSON file
+Validate → Check task exists and can be modified
+Session Check → Verify active workflow session
 ```
 
-## Replan Strategies
-
-### 1. Adjust Strategy (Default)
-Minimal changes to existing plan:
-```bash
-/task:replan IMPL-001 --strategy=adjust
-
-Adjustments for IMPL-001:
-- Updated requirements
-- Modified subtask IMPL-001.2
-- Added validation step
-- Kept 80% of original plan
+### 2. Input Processing
+```
+Detect Input Type → Identify source type
+Extract Requirements → Parse change requirements
+Analyze Impact → Determine modifications needed
 ```
 
-### 2. Rebuild Strategy
-Complete replanning from scratch:
-```bash
-/task:replan IMPL-001 --strategy=rebuild
-
-Rebuilding IMPL-001:
-- Analyzing new requirements
-- Generating new breakdown
-- Reassigning agents
-- New execution plan created
+### 3. Version Management
+```
+Create Version → Backup current task state
+Update Version → Increment task version number
+Archive → Store previous version in versions/
 ```
 
-## Usage Scenarios
-
-### Scenario 1: Requirements Change
-```bash
-/task:replan IMPL-001 --reason="Added OAuth2 requirement"
-
-Analyzing impact...
-Current plan:
-- IMPL-001.1: Basic login ✅ Complete
-- IMPL-001.2: Session management (in progress)
-- IMPL-001.3: Tests
-
-Recommended changes:
-+ Add IMPL-001.4: OAuth2 integration
-~ Modify IMPL-001.2: Include OAuth session
-~ Update IMPL-001.3: Add OAuth tests
-
-Apply changes? (y/n): y
-✅ Task replanned successfully
+### 4. Task Structure Updates
+```
+Modify Task → Update task JSON structure
+Update Subtasks → Add/remove/modify as needed
+Update Relations → Fix dependencies and hierarchy
+Update Context → Modify requirements and scope
 ```
 
-### Scenario 2: Blocked Task
-```bash
-/task:replan IMPL-003 --reason="API not ready"
-
-Task blocked analysis:
-- IMPL-003 depends on external API
-- API delayed by 2 days
-- 3 tasks depend on IMPL-003
-
-Replan options:
-1. Defer IMPL-003 and dependents
-2. Create mock API for development
-3. Reorder to work on independent tasks
-
-Select option: 2
-
-Creating new plan:
-+ IMPL-003.0: Create API mock
-~ IMPL-003.1: Use mock for development
-~ Add note: Replace mock when API ready
+### 5. Document Synchronization
+```
+Update IMPL_PLAN → Regenerate task section
+Update TODO_LIST → Sync task hierarchy (if exists)
+Update Session → Reflect changes in workflow state
 ```
 
-### Scenario 3: Failed Execution
-```bash
-/task:replan IMPL-002 --reason="execution failed"
-
-Failure analysis:
-- Failed at: Testing phase
-- Reason: Performance issues
-- Impact: Blocks 2 downstream tasks
-
-Replan approach:
-1. Break down into smaller tasks
-2. Add performance optimization task
-3. Adjust testing approach
-
-New structure:
-IMPL-002 (failed) → 
-├── IMPL-002.1: Core functionality (smaller scope)
-├── IMPL-002.2: Performance optimization
-├── IMPL-002.3: Load testing
-└── IMPL-002.4: Integration
-
-✅ Replanned with focus on incremental delivery
+### 6. Change Documentation
+```
+Create Change Log → Document all modifications
+Generate Summary → Create replan report
+Update History → Add to task replan history
 ```
 
-## Global Replanning

-
-Plan versions for impl-001 (from JSON file):
-v3 (current): 4 subtasks, 2 complete - JSON files: impl-001.1.json to impl-001.4.json
-v2: 3 subtasks (archived) - Backup: .task/archive/impl-001-v2-backup.json
-v1: 2 subtasks (initial) - Backup: .task/archive/impl-001-v1-backup.json
-
-Version files available:
-- Current: .task/impl-001.json
-- Backups: .task/archive/impl-001-v[N]-backup.json
-- Change log: .summaries/replan-history-impl-001.md
-
-Rollback to version: 2
-⚠️ This will:
-- Restore JSON files from backup
-- Regenerate TODO_LIST.md structure
-- Update workflow-session.json

 ```
 
 ## Error Handling
 
+### Input Validation Errors
 ```bash
-# Cannot replan completed task
-❌ Task IMPL-001 is completed
-→ Create new task instead
+# Task not found
+❌ Task impl-5 not found in current session
+→ Check task ID with /context
 
-# No reason provided
-⚠️ Please provide reason for replanning
-→ Use --reason="explanation"
+# No input provided
+❌ Please specify changes needed for replanning
+→ Use descriptive text or --detailed/--interactive
 
-# Conflicts detected
-⚠️ Replan conflicts with IMPL-002
-→ Resolve with --force or adjust plan
+# Task completed
+⚠️ Task impl-1 is completed (cannot replan)
+→ Create new task for additional work
+
+# File not found
+❌ File updated-specs.md not found
+→ Check file path and try again
 ```
 
-## File Output Summary

 # Workflow Action Plan Command (/workflow:action-plan)
 
 ## Overview
-Creates actionable implementation plans based on brainstorming insights or direct user input. Establishes project structure, understands existing workflow context, and generates executable plans with proper task decomposition and resource allocation.
+Creates actionable implementation plans from multiple input sources including direct text, files, issues, templates, interactive sessions, and brainstorming outputs. Supports flexible requirement gathering with optional task decomposition.
 
 ## Core Principles
 **System:** @~/.claude/workflows/unified-workflow-system-principles.md
 
-## Input Sources & Planning Approaches
+## Input Sources & Processing
 
-### Brainstorming-Based Planning (--from-brainstorming)
-**Prerequisites**: Completed brainstorming session with multi-agent analysis
-**Input Sources**:
-- `.workflow/WFS-[topic-slug]/.brainstorming/[agent]/analysis.md` files
-- `.workflow/WFS-[topic-slug]/.brainstorming/synthesis-analysis.md`
-- `.workflow/WFS-[topic-slug]/.brainstorming/recommendations.md`
-- `workflow-session.json` brainstorming phase results
-
-### Direct User Input Planning (--skip-brainstorming)
-**Prerequisites**: User provides task description and requirements
-**Input Sources**:
-- User task description and requirements
-- Existing project structure analysis
-- Session context from workflow-session.json (if exists)
-
-### Session Context Detection
-
-⚠️ **CRITICAL**: Before planning, MUST check for existing active session to avoid creating duplicate sessions.
-
-**Session Check Process:**
-1. **Query Session Registry**: Check `.workflow/session_status.jsonl` for active sessions. If the file doesn't exist, create it.
-2. **Session Selection**: Use existing active session or create new one only if none exists  
-3. **Context Integration**: Load existing session state and brainstorming outputs
-
-```json
-{
-  "session_id": "WFS-[topic-slug]",
-  "type": "simple|medium|complex", 
-  "current_phase": "PLAN",
-  "session_source": "existing_active|new_creation",
-  "brainstorming": {
-    "status": "completed|skipped",
-    "output_directory": ".workflow/WFS-[topic-slug]/.brainstorming/",
-    "insights_available": true|false
-  }
-}
-```
-
-### Planning Depth & Document Generation
-- **Simple**: Skip detailed planning, generate minimal IMPL_PLAN.md or go direct to IMPLEMENT
-- **Medium**: Standard planning with IMPL_PLAN.md generation (1-2 agents)
-- **Complex**: Full planning with comprehensive IMPL_PLAN.md (enhanced structure)
-
-## Execution Flow
-
-### Phase 1: Context Understanding & Structure Establishment
-1. **Session Detection & Selection**: 
-   - **Check Active Sessions**: Query `.workflow/session_status.jsonl` for existing active sessions. If the file doesn't exist, create it.
-   - **Session Priority**: Use existing active session if available, otherwise create new session
-   - **Session Analysis**: Read and understand workflow-session.json from selected session
-   - Detect existing brainstorming outputs
-   - Identify current phase and progress
-   - Understand project context and requirements
-
-2. **File Structure Assessment**: 
-   - **If brainstorming exists**: Verify `.workflow/WFS-[topic-slug]/.brainstorming/` structure
-   - **If no structure exists**: Create complete workflow directory structure
-   - **Document Discovery**: Identify all existing planning documents
-
-3. **Input Source Determination**:
-   - **From Brainstorming**: Read all agent analyses and synthesis documents
-   - **Skip Brainstorming**: Collect user requirements and context directly
-   - **Hybrid**: Combine existing insights with new user input
-
-### Phase 2: Context Integration & Requirements Analysis
-4. **Requirements Synthesis**:
-   - **From Brainstorming**: Integrate multi-agent perspectives and recommendations
-   - **From User Input**: Analyze and structure user-provided requirements
-   - **Gap Analysis**: Identify missing information and clarify with user
-
-5. **Complexity Assessment**: Determine planning depth needed based on:
-   - Scope of requirements (brainstorming insights or user input)
-   - Technical complexity indicators
-   - Resource and timeline constraints
-   - Risk assessment from available information
-
-### Phase 3: Document Generation & Planning
-6. **Create Document Directory**: Setup `.workflow/WFS-[topic-slug]/` structure (if needed)
-
-7. **Execute Planning**:
-   - **Simple**: Minimal documentation, direct to IMPLEMENT
-   - **Medium**: Generate IMPL_PLAN.md with task breakdown
-   - **Complex**: Generate comprehensive IMPL_PLAN.md with staged approach and risk assessment
-
-8. **Auto-Generate Tasks (NEW)**: Parse IMPL_PLAN.md and automatically create corresponding task JSON files
-   - **Extract Tasks**: Parse task identifiers (IMPL-001, IMPL-002, etc.) from plan
-   - **Create Task Files**: Generate `.task/impl-*.json` files with plan context
-   - **Link to Plan**: Include `source_plan_ref` field linking tasks back to plan sections
-   - **Set Dependencies**: Establish task dependencies based on plan structure
-
-9. **Update Session**: Mark PLAN phase complete with document references and generated task list
-
-10. **Link Documents**: Update JSON state with generated document paths and task file references
-
-## Automated Task Generation (Single Source of Truth Integration)
-
-### Planning-to-Execution Automation
-**NEW FEATURE**: Eliminates the gap between planning and execution by automatically creating executable task files from planning documents.
-
-### Task Extraction Process
-1. **Parse IMPL_PLAN.md**: Scan for task identifiers in standardized format:
-   - `IMPL-001`, `IMPL-002`, etc. (main tasks)
-   - `IMPL-1.1`, `IMPL-1.2`, etc. (subtasks)
-   - Task titles and descriptions from plan sections
-
-2. **Generate Task JSON Files**: For each identified task, create structured JSON:
-```json
-{
-  "id": "IMPL-001",
-  "title": "Foundation/Infrastructure setup",
-  "status": "pending", 
-  "type": "infrastructure",
-  "agent": "code-developer",
-  "effort": "2h",
-  
-  "context": {
-    "inherited_from": "WFS-[topic-slug]",
-    "source_plan_ref": "IMPL_PLAN.md#phase-1-foundation",
-    "requirements": ["Extracted from plan description"],
-    "scope": ["Derived from plan context"],
-    "acceptance": ["Extracted from success criteria"]
-  },
-  
-  "dependencies": {
-    "upstream": [],
-    "downstream": ["IMPL-002"],
-    "phase_group": "Phase 1: Foundation"
-  },
-  
-  "metadata": {
-    "created_at": "2025-09-07T15:00:00Z",
-    "created_by": "workflow:action-plan",
-    "auto_generated": true,
-    "plan_version": "1.0"
-  }
-}
-```
-
-3. **Link Bidirectionally**: 
-   - Task files reference plan sections
-   - Session state includes all generated task IDs
-   - Ready for immediate execution via `/task:execute`
-
-### Benefits of Automation
-- **Zero Manual Task Creation**: Plans immediately become executable
-- **Consistency**: All tasks derive from same authoritative plan
-- **Traceability**: Clear linkage from requirements through plan to tasks
-- **Immediate Execution**: Can run `/task:execute IMPL-001` immediately after planning
-
-## Session State Analysis & Document Understanding
-
-### Workflow Session Discovery
-**Command**: `workflow:action-plan` automatically detects and analyzes:
-
-**Session Detection Process**:
-1. **Find Active Sessions**: Locate `.workflow/WFS-*/workflow-session.json` files
-2. **Session Validation**: Verify session completeness and current phase
-3. **Context Extraction**: Read session metadata, progress, and phase outputs
-
-**Session State Analysis**:
-```json
-{
-  "session_id": "WFS-user-auth-system", 
-  "current_phase": "PLAN",
-  "brainstorming": {
-    "status": "completed",
-    "agents_completed": ["system-architect", "ui-designer", "security-expert"],
-    "synthesis_available": true,
-    "recommendations_count": 12
-  },
-  "documents": {
-    "brainstorming": {
-      "system-architect/analysis.md": {"status": "available", "insights": ["scalability", "microservices"]},
-      "synthesis-analysis.md": {"status": "available", "key_themes": ["security-first", "user-experience"]}
-    }
-  }
-}
-```
-
-### Document Intelligence & Content Understanding
-**Process**: Action planning reads and interprets existing workflow documents
-
-**Brainstorming Document Analysis**:
-- **Agent Analyses**: Extract key insights, recommendations, and constraints from each agent
-- **Synthesis Reports**: Understand cross-perspective themes and convergent solutions  
-- **Recommendation Prioritization**: Identify high-impact, actionable items
-- **Context Preservation**: Maintain user requirements and constraints from discussions
-
-**Content Integration Strategy**:
-- **Technical Requirements**: From system-architect, data-architect, security-expert analyses
-- **User Experience**: From ui-designer, user-researcher perspectives
-- **Business Context**: From product-manager, business-analyst insights
-- **Implementation Constraints**: From all agent recommendations and user discussions
-
-**Gap Detection**:
-- Identify missing technical specifications
-- Detect undefined user requirements
-- Find unresolved architectural decisions
-- Highlight conflicting recommendations requiring resolution

-
-### Integration with Issues
-When issues are created, replanning can be automatically triggered:
+### Template-based Input
 ```bash
-# Create issue then replan
-/workflow:issue create --type=feature "OAuth2 support" 
-/workflow:action-plan --replan --trigger=new-issue --issue=ISS-001
+/workflow:action-plan --template web-api
+/workflow:action-plan --template mobile-app "user management"
+```
+**Available templates**:
+- `web-api`: REST API development template
+- `mobile-app`: Mobile application template
+- `database-migration`: Database change template
+- `security-feature`: Security implementation template
+**Processing**:
+- Load template structure and best practices
+- Prompt for template-specific parameters
+- Customize template with user requirements
+- Generate plan following template patterns
+
+### Interactive Mode
+```bash
+/workflow:action-plan --interactive
+```
+**Guided Process**:
+1. **Project Type**: Select development category
+2. **Requirements**: Structured requirement gathering
+3. **Constraints**: Technical and resource limitations
+4. **Success Criteria**: Define completion conditions
+5. **Plan Generation**: Create comprehensive plan
+
+### Brainstorming Integration
+```bash
+/workflow:action-plan --from-brainstorming
+```
+**Prerequisites**: Completed brainstorming session
+**Processing**:
+- Read multi-agent brainstorming analyses
+- Synthesize recommendations and insights
+- Integrate diverse perspectives into unified plan
+- Preserve brainstorming context and decisions
+
+### Web-based Input
+```bash
+/workflow:action-plan --from-url "https://github.com/project/issues/45"
+/workflow:action-plan --from-url "https://docs.example.com/spec"
+```
+**Processing**:
+- Fetch content from web URLs
+- Parse structured requirements from web pages
+- Extract technical specifications
+- Handle GitHub issues, documentation sites, specs
+
+## Complexity Levels
+
+### Simple (Default)
+```bash
+/workflow:action-plan "Build chat system"
+```
+**Output**: IMPL_PLAN.md document only
+**Use case**: Documentation-focused planning, quick overviews
+**Content**: Structured plan with task descriptions
+
+### Decompose
+```bash
+/workflow:action-plan "Build chat system" --complexity=decompose
+```
+**Output**: IMPL_PLAN.md + task JSON files
+**Use case**: Full workflow execution with automated task system
+**Content**: Plan document + extracted task files in .task/ directory
+
+## Input Processing Pipeline
+
+### 1. Input Detection
+```pseudo
+function detect_input_type(args):
+  if starts_with("--from-file"):
+    return "file"
+  elif starts_with("--from-issue"):
+    return "issue"
+  elif starts_with("--template"):
+    return "template"
+  elif args == "--interactive":
+    return "interactive"
+  elif args == "--from-brainstorming":
+    return "brainstorming"
+  elif starts_with("--from-url"):
+    return "url"
+  else:
+    return "direct_text"
 ```
 
-## Integration with Workflow System
+### 2. Content Extraction
+**Per Input Type**:
+- **Direct Text**: Parse natural language requirements
+- **File**: Read file contents and structure
+- **Issue**: Load issue data and related context
+- **Template**: Load template and gather parameters
+- **Interactive**: Conduct guided requirement session
+- **Brainstorming**: Read brainstorming outputs
+- **URL**: Fetch web content and parse
 
-### Action Planning Integration Points
-**Prerequisite Commands**:
-- `/workflow:session start` → Initialize workflow session
-- `/brainstorm` → (Optional) Multi-agent brainstorming phase
+### 3. Requirement Analysis
+- Structure extracted information
+- Identify tasks and dependencies
+- Determine technical requirements
+- Extract success criteria
+- Assess complexity and scope
 
-**Action Planning Execution**:
-- `/workflow:action-plan --from-brainstorming` → Plan from completed brainstorming
-- `/workflow:action-plan --skip-brainstorming "task description"` → Plan from user input  
-- `/workflow:action-plan --replan` → Revise existing plans
+### 4. Plan Generation
+- Create IMPL_PLAN.md with structured content
+- Include requirements, tasks, and success criteria
+- Maintain traceability to input sources
+- Format for readability and execution
 
-**Follow-up Commands**:
-- `/workflow:implement` → Execute the action plan
-- `/workflow:status` → View current workflow state
-- `/task:create` → Create specific implementation tasks
-- `/workflow:review` → Validate completed implementation
+### 5. Optional Decomposition
+**If --complexity=decompose**:
+- Parse IMPL_PLAN.md for task identifiers
+- Create .task/impl-*.json files
+- Establish task relationships
+- Update session with task references
+
+## Session Management
+
+### Session Check Process
+⚠️ **CRITICAL**: Check for existing active session before planning
+
+1. **Query Session Registry**: Check `.workflow/session_status.jsonl`
+2. **Session Selection**: Use existing active session or create new
+3. **Context Integration**: Load session state and existing context
 
 ### Session State Updates
-After action planning completion:
 ```json
 {
-  "current_phase": "IMPLEMENT",
+  "current_phase": "PLAN",
+  "input_source": "direct_text|file|issue|template|interactive|brainstorming|url",
+  "input_details": {
+    "type": "detected_input_type",
+    "source": "input_identifier_or_path",
+    "processed_at": "2025-09-08T15:00:00Z"
+  },
   "phases": {
-    "BRAINSTORM": {"status": "completed|skipped"},
     "PLAN": {
       "status": "completed",
-      "input_source": "brainstorming|user_input", 
+      "complexity": "simple|decompose",
       "documents_generated": ["IMPL_PLAN.md"],
-      "tasks_identified": ["IMPL-001", "IMPL-002", "IMPL-003"],

-# Workflow Implement Command (/workflow:implement)
-
-## Overview
-Executes implementation phase with three complexity modes (simple/medium/complex), replacing separate complexity commands.
-
-## Core Principles
-  
-**Session Management:** @~/.claude/workflows/session-management-principles.md
-
-## Complexity Modes
-
-### Simple Mode (Single file, bug fixes)
-```bash
-/workflow:implement --type=simple
-```
-**Agent Flow:** code-developer → code-review-agent  
-**TodoWrite:** 3-4 items  
-**Documents:** TODO_LIST.md + IMPLEMENTATION_LOG.md (auto-generated)
-- Streamlined planning, direct implementation
-- Quick review cycle
-- < 2 hours effort
-
-### Medium Mode (Multi-file features)
-```bash
-/workflow:implement --type=medium
-```
-**Agent Flow:** planning-agent → code-developer → code-review-agent  
-**TodoWrite:** 5-7 items  
-**Documents:** IMPL_PLAN.md + TODO_LIST.md (auto-triggered)
-- Structured planning with hierarchical JSON task decomposition
-- Test-driven development
-- Comprehensive review
-- 2-8 hours effort
-
-### Complex Mode (System-level changes)
-```bash
-/workflow:implement --type=complex
-```
-**Agent Flow:** planning-agent → code-developer → code-review-agent → iterate  
-**TodoWrite:** 7-10 items  
-**Documents:** IMPL_PLAN.md + TODO_LIST.md (mandatory)
-- Detailed planning with mandatory 3-level JSON task hierarchy
-- Risk assessment and quality gates
-- Multi-faceted review with multiple iterations
-- > 8 hours effort
-
-## Execution Flow
-
-1. **Detect Complexity** (if not specified)
-   - Read from workflow-session.json
-   - Auto-detect from task description
-   - Default to medium if unclear
-
-2. **Initialize Based on Complexity**
-   
-   **Simple:**
-   - Use existing IMPL_PLAN.md (minimal updates)
-   - Direct JSON task creation (impl-*.json)
-   - Minimal state tracking
-   
-   **Medium:**
-   - Update IMPL_PLAN.md with implementation strategy
-   - Auto-trigger TODO_LIST.md creation
-   - Create hierarchical JSON tasks (impl-*.*.json up to 2 levels)
-   - Standard agent flow
-   
-   **Complex:**
-   - Comprehensive IMPL_PLAN.md with risk assessment
-   - Mandatory TODO_LIST.md with progress tracking
-   - Full 3-level JSON task hierarchy (impl-*.*.*.json)
-   - Full iteration support with cross-document synchronization
-
-3. **Update Session**

-       }
-     }
-   }
-   ```
-
-4. **Execute Agent Flow**
-   - Create TodoWrite entries
-   - Execute agents based on complexity
-   - Track checkpoints
-   - Support pause/resume
-
-## Document Generation Rules
-
-### Decomposition Triggers (Medium Workflows)
-Task decomposition documents generated when ANY condition met:
-- Task involves >3 modules/components
-- >5 distinct subtasks identified  
-- Complex interdependencies detected
-- Estimated effort >4 hours
-- Cross-team coordination required
-
-### Mandatory Generation (Complex Workflows)
-Always generates complete document suite:
-- **Enhanced IMPL_PLAN.md structure** - Hierarchical task breakdown integrated into main plan
-- **TODO_LIST.md** - Progress tracking with cross-links
-- Links to existing IMPL_PLAN.md from planning phase
-
-### Document-JSON Synchronization
-- **Document Creation** → Update workflow session with document references
-- **Task Status Changes** → Update TODO_LIST.md progress
-- **Task Completion** → Mark items complete in checklist
-- **New Tasks Added** → Add to both JSON and enhanced implementation plan
-

+# Workflow Vibe Command (/workflow:vibe)
+
+## Overview
+Coordinates multiple agents for executing existing workflow tasks through automatic discovery and intelligent task orchestration. Analyzes workflow folders, checks task statuses, and coordinates agent execution based on discovered plans.
+
+## Core Principles
+  
+**Session Management:** @~/.claude/workflows/session-management-principles.md
+**Agent Orchestration:** @~/.claude/workflows/agent-orchestration-patterns.md
+
+## Vibe Philosophy
+
+The "vibe" approach focuses on:
+- **Discovery-first execution** - Automatically discover existing plans and tasks
+- **Status-aware coordination** - Execute only tasks that are ready
+- **Context-rich agent assignment** - Use complete task JSON data for agent context  
+- **Dynamic task orchestration** - Coordinate based on discovered task relationships
+- **Progress tracking** - Update task status after agent completion
+
+**IMPORTANT**: Gemini context analysis is automatically applied based on discovered task scope and requirements.
+
+## Execution Flow
+
+### 1. Discovery & Analysis Phase
+```
+Workflow Discovery:
+├── Locate workflow folder (provided or current session)
+├── Load workflow-session.json for session state  
+├── Scan .task/ directory for all task JSON files
+├── Read IMPL_PLAN.md for workflow context
+├── Analyze task statuses and dependencies
+└── Determine executable tasks
+```
+
+**Discovery Logic:**
+- **Folder Detection**: Use provided folder or find current active session
+- **Task Inventory**: Load all impl-*.json files from .task/ directory
+- **Status Analysis**: Check pending/active/completed/blocked states
+- **Dependency Check**: Verify all task dependencies are met
+- **Execution Queue**: Build list of ready-to-execute tasks

+### 2. TodoWrite Coordination Setup
+**Always First**: Create comprehensive TodoWrite based on discovered tasks
+
+```markdown
+# Workflow Vibe Coordination
+*Session: WFS-[topic-slug]*
+
+## Execution Plan
+- [ ] **TASK-001**: [Agent: planning-agent] [GEMINI_CLI_REQUIRED] Design auth schema (impl-1.1)
+- [ ] **TASK-002**: [Agent: code-developer] [GEMINI_CLI_REQUIRED] Implement auth logic (impl-1.2)  
+- [ ] **TASK-003**: [Agent: code-review-agent] Review implementations
+- [ ] **TASK-004**: Update task statuses and session state
+```
+
+### 3. Agent Context Assignment
+For each executable task:
+
+```json
+{
+  "task": {
+    "id": "impl-1.1",
+    "title": "Design auth schema",
+    "context": {
+      "requirements": ["JWT authentication", "User model design"],
+      "scope": ["src/auth/models/*"],
+      "acceptance": ["Schema validates JWT tokens"]
+    }
+  },
+  "workflow": {
+    "session": "WFS-user-auth", 
+    "phase": "IMPLEMENT",
+    "plan_context": "Authentication system with OAuth2 support"
+  },
+  "focus_modules": ["src/auth/", "tests/auth/"],
+  "gemini_required": true
+}
+```
+
+**Context Assignment Rules:**
+- **Complete Context**: Use full task JSON context for agent execution
+- **Workflow Integration**: Include session state and IMPL_PLAN.md context
+- **Scope Focus**: Direct agents to specific files from task.context.scope
+- **Gemini Flags**: Automatically add [GEMINI_CLI_REQUIRED] for multi-file tasks
+
+### 4. Agent Execution & Progress Tracking
+
+```bash
+Task(subagent_type="code-developer",
+     prompt="[GEMINI_CLI_REQUIRED] Implement authentication logic based on schema",
+     description="Execute impl-1.2 with full workflow context and status tracking")
+```
+
+**Execution Protocol:**
+- **Sequential Execution**: Respect task dependencies and execution order
+- **Progress Monitoring**: Track through TodoWrite updates
+- **Status Updates**: Update task JSON status after each completion
+- **Cross-Agent Handoffs**: Coordinate results between related tasks
+

+### Task Status Assessment
+```pseudo
+function analyze_tasks(task_files):
+  executable_tasks = []
+  
+  for task in task_files:
+    if task.status == "pending" and dependencies_met(task):
+      if task.subtasks.length == 0:  // leaf task
+        executable_tasks.append(task)
+      else:  // container task - check subtasks
+        if all_subtasks_ready(task):
+          executable_tasks.extend(task.subtasks)
+  
+  return executable_tasks
+```
+
+### Automatic Agent Assignment
+Based on discovered task data:
+- **task.agent field**: Use specified agent from task JSON
+- **task.type analysis**: 
+  - "feature" → code-developer
+  - "test" → test-agent  
+  - "docs" → docs-agent
+  - "review" → code-review-agent
+- **Gemini context**: Auto-assign based on task.context.scope and requirements
+
+## Agent Task Assignment Patterns
+
+### Discovery-Based Assignment
+```bash
+# Agent receives complete discovered context
+Task(subagent_type="code-developer",
+     prompt="[GEMINI_CLI_REQUIRED] Execute impl-1.2: Implement auth logic
+     
+     Context from discovery:
+     - Requirements: JWT authentication, OAuth2 support
+     - Scope: src/auth/*, tests/auth/*
+     - Dependencies: impl-1.1 (completed)
+     - Workflow: WFS-user-auth authentication system",
+     
+     description="Agent executes with full discovered context")
+```
+
+### Status Tracking Integration
+```bash  
+# After agent completion, update discovered task status
+update_task_status("impl-1.2", "completed")
+mark_dependent_tasks_ready(task_dependencies)
+```
+
+## Coordination Strategies
+
+### Automatic Coordination
+- **Task Dependencies**: Execute in dependency order from discovered relationships
+- **Agent Handoffs**: Pass results between agents based on task hierarchy  
+- **Progress Updates**: Update TodoWrite and JSON files after each completion
+
+### Context Distribution
+- **Rich Context**: Each agent gets complete task JSON + workflow context
+- **Focus Areas**: Direct agents to specific files from task.context.scope
+- **Inheritance**: Subtasks inherit parent context automatically
+- **Session Integration**: Include workflow-session.json state in agent context
+
+## Status Management
+
+### Task Status Updates
+```json
+// Before execution
+{
+  "id": "impl-1.2",
+  "status": "pending",
+  "execution": {
+    "attempts": 0,
+    "last_attempt": null
+  }
+}
+
+// After execution  
+{
+  "id": "impl-1.2", 
+  "status": "completed",
+  "execution": {
+    "attempts": 1,
+    "last_attempt": "2025-09-08T14:30:00Z"
+  }
+}
+```
+
+### Session State Updates
+```json
+{
+  "current_phase": "VIBE",
+  "last_vibe_execution": "2025-09-08T14:30:00Z"
+}
+```
+
+## Error Handling & Recovery
+
+### Discovery Issues
+```bash
+# No workflow found
+❌ No workflow folder found
+→ Use: /workflow init "project name" first
+
+# No executable tasks  
+⚠️ All tasks completed or blocked
+→ Check: /context for task status overview
+
+# Missing task files
+❌ Task impl-1.2 referenced but JSON file missing
+→ Fix: Recreate task or repair references
+```
+
+### Execution Recovery
+- **Failed Agent**: Retry with adjusted context or different agent
+- **Blocked Dependencies**: Skip and continue with available tasks
+- **Context Issues**: Reload from JSON files and session state
+
+## Integration Points
+
+### Automatic Behaviors
+- **Discovery on start** - Analyze workflow folder structure
+- **TodoWrite coordination** - Generate based on discovered tasks  
+- **Agent context preparation** - Use complete task JSON data
+- **Status synchronization** - Update JSON files after completion
+
+### Next Actions
+```bash  
+# After /workflow:vibe execution
+/context                  # View updated task status
+/task:execute impl-X      # Execute specific remaining tasks  
+/workflow:review          # Move to review phase when complete
+```
+
+## Related Commands
+
+- `/context` - View discovered tasks and current status
+- `/task:execute` - Execute individual tasks (user-controlled)
+- `/task:status` - Check task progress and dependencies
+- `/workflow:review` - Move to review phase after completion
+

+
+**System ensures**: Intelligent task discovery with context-rich agent coordination and automatic progress tracking

 6.  **Checkpoint Safety**: State is saved automatically after each agent completes its work.
 7.  **Interrupt/Resume**: The system must support full state preservation and restoration.
 
-### Implementation Prerequisites Principle
+## Context Management
 
-**Deliverable Validation**: Code modification agents can only execute when proper planning deliverables exist.
+### Gemini Context Protocol
+**Context Integration**: Agents use Gemini CLI for context gathering when needed, with memory-gemini-bridge agent handling complex analysis.
 
-**Required Artifacts Before Implementation** (at least one must exist):
-- `IMPL_PLAN.md`: Must contain detailed implementation strategy
-- `.chat/` sessions: Context analysis supporting planning decisions
-- Task definitions: JSON task files with clear acceptance criteria
-- Complexity assessment: Validated task complexity and scope
+**CLI Guidelines Reference**: Follow @~/.cluade/workflows/gemini-cli-guidelines.md for consistency and `memory-gemini-bridge` agent for comprehensive analysis.
 
-**Validation Protocol**:
-```pseudo
-FUNCTION validate_implementation_prerequisites():
-  artifacts_found = 0
-  
-  IF exists("IMPL_PLAN.md") AND valid_content("IMPL_PLAN.md"):
-    artifacts_found += 1

+### 🎯 Gemini CLI Requirements by Task Complexity
 
-### Core Workflow Process
+#### 🚀 Simple Tasks (CLI Optional)
+**Task Examples**: Single file modifications, documentation updates, text changes, simple bug fixes
+**CLI Decision**: Optional - only when unfamiliar patterns encountered
+**Context Scope**: Basic guidelines and patterns
 
-`TodoWrite Creation` **->** `Context Collection` **->** `Implementation` **->** `Quality Assurance` **->** `State Update`
-
-### Interrupt & Resume Protocol
-
-**Checkpoint Strategy Flow:**
-`Agent Completes` **->** `Save State (Todo + Context)` **->** `Check for Interrupt Signal` **->** `Continue or Stop`
-
-**State Components for Resume**:
-- TodoWrite current state
-- Agent output chain
-- Accumulated context
-- Planning documents
-- `.chat/` analysis history
-
-### Agent Selection Logic
-
-```pseudo
-FUNCTION select_agent_for_task(task_complexity):
-  CASE task_complexity:
-    WHEN 'Research/Analysis':
-      RETURN "General-Purpose" // For research, file analysis
-    WHEN 'Simple Implementation':
-      RETURN "Code Developer" // For implementation, TDD, algorithms
-    WHEN 'Complex Features (3+ components)':
-      RETURN ["Action Planning", "Code Developer", "Code Review"] // Multi-stage agent chain
-    WHEN 'Full Lifecycle':
-      RETURN "Boomerang" // For full workflow orchestration
-    WHEN 'Post-Implementation':
-      RETURN "Code Review" // For quality validation, security, compliance
-END FUNCTION
-```
-
-### Agent Output Standards
-
-**Action Planning Agent**:
-```
-PLAN_SUMMARY: [One-line summary]
-STEPS: [Numbered deliverables]
-SUCCESS_CRITERIA: [Measurable standards]
-TODOWRITE_ENTRIES: [TodoWrite items created for each stage/subtask]
-```
-
-**Code Developer Agent**:
-```
-PREREQUISITE_VALIDATION: [IMPL_PLAN.md and .chat/ sessions verified]
-IMPLEMENTATION_SUMMARY: [What was built]
-FILES_MODIFIED: [File list with changes]
-CONTEXT_REFERENCES: [Links to supporting .chat/ analysis]
-TODOWRITE_UPDATES: [Progress status updates made during implementation]
-READY_FOR_REVIEW: [YES/NO with reason]
-```
-
-**Code Review Agent**:
-```
-REVIEW_STATUS: [PASS/ISSUES_FOUND/CRITICAL_ISSUES]
-QUALITY_SCORE: [1-10]
-TODOWRITE_COMPLETION: [Tasks marked as completed after validation]
-RECOMMENDATION: [APPROVE/FIX_REQUIRED/REVISION_NEEDED]
-```
+#### 🎯 Medium Tasks (CLI Recommended)  
+**Task Examples**: Multi-file features, component modifications, API endpoint additions
+**CLI Decision**: Recommended for consistency and quality
+**Context Scope**: Guidelines + architecture + feature patterns
+**Standard Context Collection**:
+```bash
+gemini --all-files -p "@{**/*CLAUDE.md} Guidelines for: [task]"

-## Single Source of Truth Architecture
+## Pure Generation Architecture
 
-### 1. Data Authority (Simplified)
+### JSON as Single Source of Truth
 
-#### JSON Files Own (ONLY Authoritative Source)
-- **ALL Task State**: Complete task definitions, status, progress, metadata
-- **Hierarchical Relationships**: Parent-child links, depth management  
-- **Execution State**: pending/active/completed/blocked/failed
-- **Progress Data**: Percentages, timing, checkpoints
-- **Agent Assignment**: Current agent, execution history
-- **Dependencies**: Task relationships across all hierarchy levels
-- **Session Metadata**: Timestamps, versions, attempt counts
-- **Runtime State**: Current attempt, active processes
+**JSON Files Own Everything:**
+- All task state and metadata
+- All relationships and dependencies  
+- All execution history
+- All progress information
 
-#### Documents Are Read-Only Views (Generated Only)
-- **IMPL_PLAN.md**: Static planning document (manually created, rarely changes)
-- **TODO_LIST.md**: **Generated view** from JSON files (never manually edited)
-- **Progress Reports**: **Generated views** from JSON data
-- **Status Displays**: **Generated views** from JSON state
+**Documents Are Temporary Views:**
+- Generated only when requested
+- Never stored permanently
+- Never parsed back to JSON
+- No state persistence in markdown
 
-#### No Shared Responsibility (Eliminates Conflicts)
-- **Single Direction Flow**: JSON → Markdown (never Markdown → JSON)
-- **No Synchronization**: Documents are generated, not synchronized
-- **No Conflicts**: Only one source of truth eliminates data conflicts
+### No Synchronization Needed
 
-### 2. View Generation (Replaces Synchronization)
+**Eliminated Concepts:**
+- Bidirectional sync
+- Document parsing
+- Conflict resolution
+- Sync state tracking
+- Update coordination
 
-#### No Document → JSON Flow (Eliminated)
-**Documents are read-only**: No parsing, no status updates from documents
-**No bidirectional sync**: Documents cannot modify JSON state
-**No conflict resolution needed**: Single direction eliminates conflicts
+**Single Flow Only:**
+```
+JSON Files → On-Demand Generation → Temporary Views → Display
+```
 
-#### JSON → View Generation (On Demand)
-**Trigger Events**:
-- User requests context view (`/context`)
-- Task status changed in JSON files  
-- View generation requested by commands
 
-**Actions**:
+### Generation Process
+
+```pseudo
+function generate_view(format, filters):
+  // Load all JSON data
+  tasks = load_all_task_json_files()
+  session = load_workflow_session()
+  
+  // Generate requested view
+  switch format:
+    case 'tasks':
+      return generate_task_list_view(tasks)
+    case 'progress':
+      return generate_progress_view(tasks, session)
+    case 'hierarchy':
+      return generate_hierarchy_view(tasks)
+    default:
+      return generate_overview(tasks, session)
+```
+
+### View Examples
+
+#### Task List View (Generated)
+```markdown
+# Current Tasks
+
+## Active Tasks
+- [⚠️] impl-1: Build authentication module (code-developer)
+- [⚠️] impl-2: Setup user management (code-developer)
+
+## Completed Tasks  
+- [✅] impl-0: Project setup
+
+## Task Dependencies
+- impl-2 → depends on → impl-1
+```
+
+
+## Data Operations
+
+### Task Updates (JSON Only)
+
 ```javascript
-// Pseudo-code for view generation process  
-on_view_request(view_type, options) {
-  const task_data = load_all_task_json_files();
-  const session_data = load_workflow_session();
-  
-  if (view_type === 'todo_list') {
-    const todo_view = generate_todo_list_view(task_data);
-    return render_markdown_view(todo_view);
-  }
-  
-  if (view_type === 'progress') {
-    const progress = calculate_progress_from_json(task_data);
-    return render_progress_view(progress, session_data);
-  }
-  
-  if (view_type === 'status') {
-    const status = compile_status_from_json(task_data, session_data);
-    return render_status_view(status);
-  }
+// Update task status
+function update_task_status(task_id, new_status) {
+  const task_file = `.task/${task_id}.json`
+  const task = load_json(task_file)
+  task.status = new_status
+  task.meta.updated = current_timestamp()
+  save_json(task_file, task)
+  // No document updates needed - views generated on demand
 }
 ```
 
-### 3. View Generation Process (Replaces Real-Time Sync)
+### Session Updates (Minimal)
 
-#### On-Demand View Process
-```
-1. Command Request → User requests view (`/context`)
-2. JSON Loader → Reads all task JSON files  
-3. Data Processor → Calculates progress, status, hierarchy
-4. View Generator → Creates markdown representation
-5. Display → Returns formatted view to user
-```
-
-#### Context Command (Replaces Sync Commands)
-```bash
-# Generate todo list view
-/context
-
-# Generate task-specific view  
-/context IMPL-001
-
-# Generate progress view
-/context --format=progress
-
-# Generate status view with health check
-/context --health-check
-```
-
-## No Conflict Resolution Needed (Architecture Benefit)
-
-### Eliminated Conflict Types
-
-#### Conflicts That No Longer Exist
-- **Timestamp Conflicts**: No bidirectional updates means no timestamp conflicts
-- **Data Authority Conflicts**: Only JSON has authority, documents are read-only
-- **Hierarchy Conflicts**: JSON defines structure, documents display it (no conflicts)
-- **Sync State Conflicts**: No synchronization means no sync state issues
-
-### Simplified Data Model Benefits
-- **Zero Conflicts**: Single source of truth eliminates all data conflicts  
-- **No Resolution Logic**: No complex conflict detection or resolution needed
-- **Reduced Complexity**: Eliminates entire conflict resolution subsystem
-- **Improved Reliability**: Cannot have data drift or inconsistency issues
-
-## Validation and Integrity
-
-### Consistency Checks
-```bash
-/task:validate --consistency
-
-Running consistency checks:
-✅ Task IDs consistent across JSON files and TODO_LIST.md
-✅ Hierarchical relationships valid (parent-child links)
-✅ Task depth within limits (max 3 levels)
-✅ Progress calculations accurate across hierarchy
-⚠️ impl-2.1 missing from TODO_LIST.md display
-❌ impl-1.1 status mismatch (JSON: completed, TODO: pending)
-❌ Orphaned task: impl-3.2.1 has non-existent parent
-
-Issues found: 3
-Auto-fix available: 2 
-Manual review required: 1
-```
-
-### Cross-Reference Validation
-- Task IDs exist in all referenced documents
-- Document sections referenced in JSON exist
-- Progress percentages mathematically consistent
-- Dependency relationships bidirectional
-
-### Data Integrity Checks
-- JSON schema validation
-- Document structure validation  
-- Cross-file referential integrity
-- Timeline consistency validation
-
-## Performance and Scalability
-
-### Optimization Strategies
-- **Incremental Sync**: Only sync changed sections
-- **Batch Updates**: Group related changes
-- **Async Processing**: Non-blocking synchronization
-- **Caching**: Cache parsed document structures
-
-### Scalability Considerations
-- **File Size Limits**: Split large task sets across multiple files
-- **Memory Usage**: Stream processing for large document parsing
-- **I/O Optimization**: Minimize file reads/writes through batching
-
-## Error Handling and Recovery
-
-### Common Error Scenarios
-```bash
-# Document parsing error
-❌ Failed to parse TODO_LIST.md
-→ Syntax error in checkbox format at line 23
-→ Restore from JSON task data? (y/n)
-
-# JSON corruption
-❌ Invalid JSON in impl-1.2.json  
-→ Reconstruct from parent task and TODO_LIST.md? (y/n)
-
-# Hierarchy errors
-❌ Circular parent-child relationship detected: impl-1.1 → impl-1.1.1 → impl-1.1
-→ Break circular dependency? (y/n)
-
-# Missing files
-❌ TODO_LIST.md not found
-→ Regenerate from JSON task hierarchy? (y/n)
-
-# Depth violations  
-⚠️ Task impl-1.2.3.1 exceeds maximum depth (3 levels)
-→ Flatten hierarchy or promote task? (flatten/promote)
-```
-
-### Recovery Mechanisms
-- **Automatic Backup**: Git-based document versioning
-- **Rollback Options**: Restore from previous sync point
-- **Reconstruction**: Rebuild JSON from documents or vice versa
-- **Partial Recovery**: Fix individual files without full reset

-### Performance Metrics
-- Sync frequency and duration
-- Conflict rate and resolution time  
-- File size growth over time
-- Error rate and recovery success
+## Benefits of Pure Generation
 
-This JSON-document coordination system ensures reliable, consistent, and performant integration between state management and planning documentation while maintaining clear data ownership and providing robust error handling.

+- Parent-child relationships valid
+- Dependencies exist
+- Required fields present
+
+## Error Handling
+
+### Simple Error Scenarios
+```bash
+# Missing task file
+❌ Task impl-5 not found
+→ Check .task/impl-5.json exists
+
+# Invalid JSON
+❌ Parse error in impl-2.json
+→ Restore from backup or recreate task
+
+# Circular dependency  
+❌ Circular dependency: impl-1 → impl-2 → impl-1
+→ Fix dependency chain manually
+```
+
+### Recovery Strategy
+- **JSON First**: Always repair JSON files
+- **Regenerate Views**: Views are disposable, regenerate as needed
+- **Simple Rollback**: Use git to restore JSON files
+- **Manual Repair**: Direct JSON editing for complex issues
+
+## Migration from Complex System
+
+### Removed Features
+- All document parsing
+- Bidirectional synchronization  
+- Conflict resolution
+- Real-time document updates
+- Sync state tracking
+- Document metadata

+2. **Status Updates**: Update JSON file only  
+3. **View Request**: Generate from JSON on demand
+4. **Progress Check**: Calculate from JSON data
+5. **Completion**: Mark JSON as completed
+
+This pure generation system provides all the functionality of the previous complex system while eliminating synchronization overhead, conflicts, and maintenance complexity.

-## Phase-Aware Session Management
-
-### Conceptual/Planning Phase
-- Tracks planning document generation
-- Monitors task decomposition progress
-- Preserves planning context and decisions
-- Safe interruption at document boundaries
-
-### Implementation Phase
-- Integrates with existing TodoWrite system
-- Tracks agent progression and outputs
-- Maintains file modification history
-- Supports multi-agent coordination
-
-### Review Phase
-- Tracks validation and quality gates
-- Preserves review comments and decisions
-- Maintains compliance check status
-
-## Automatic Checkpoints
-
-### Checkpoint Triggers
-- **Planning Phase**:
-  - After planning document completion
-  - After task breakdown generation
-  - On user interrupt request
-
-- **Implementation Phase**:
-  - After agent completion
-  - At TodoWrite milestones
-  - After significant file changes
-  - On phase transitions
-
-- **Review Phase**:
-  - After quality check completion
-  - On validation milestones
-  - At review agent boundaries
-
-### Checkpoint Strategy
-```json
-{
-  "save_triggers": ["agent_complete", "todo_milestone", "user_interrupt"],
-  "save_data": ["agent_outputs", "file_changes", "todo_state"],
-  "resume_logic": "skip_completed_continue_sequence"
-}
-```
-
-## Cross-Phase Context Preservation
-
-### Context Chain Maintenance
-- All phase outputs preserved in session
-- Context automatically transferred between phases
-- Planning documents bridge PLAN → IMPLEMENT phases
-- Implementation artifacts bridge IMPLEMENT → REVIEW
-- Full audit trail maintained for decisions

-## Recovery Mechanisms
+## Simplified Phase Management
 
-### Automatic Recovery Logic
+### Phase-Level Tracking Only
+- **Planning Phase**: Track completion status only
+- **Implementation Phase**: Track active tasks, not detailed progress
+- **Review Phase**: Track completion status only
+
+### Minimal Checkpoint Strategy
+- **Phase Transitions**: Save state when moving between phases
+- **User Request**: Manual checkpoint on explicit user action
+- **Session End**: Final state save before closing
+
+### Checkpoint Data (Minimal)
+```json
+{
+  "save_triggers": ["phase_complete", "user_request", "session_end"],
+  "save_data": ["phase_status", "active_tasks", "session_meta"],
+  "resume_logic": "resume_from_last_phase_checkpoint"
+}
+```
+
+## Simplified Context Preservation
+
+### Essential Context Only
+- Planning documents available to implementation phase
+- Implementation results available to review phase
+- Minimal handoff data between phases
+
+### Simple State Transitions
+```json
+{
+  "phase_completed": "PLAN",
+  "next_phase": "IMPLEMENT",
+  "completed_at": "2025-09-07T10:00:00Z",
+  "artifacts": {
+    "plan_document": "IMPL_PLAN.md"
+  }
+}
+```
+
+## Simplified Recovery
+
+### Basic Recovery Logic
 ```python
 def resume_workflow():
     session = load_session()
     
     if session.current_phase == "PLAN":
-        resume_planning(session.checkpoints.plan)
+        check_plan_document_exists()
     elif session.current_phase == "IMPLEMENT":
-        resume_implementation(session.checkpoints.implement)
+        load_active_tasks()
     elif session.current_phase == "REVIEW":
-        resume_review(session.checkpoints.review)
+        check_implementation_complete()
 ```
 
-### State Validation
-- Verify required artifacts exist for resumption
-- Check file system consistency with session state
-- Validate TodoWrite synchronization
-- Ensure agent context completeness
-- Confirm phase prerequisites met
+### Minimal State Validation
+- Check current phase is valid
+- Verify session directory exists
+- Confirm basic file structure
 
-### Recovery Strategies
-- **Complete Recovery**: Full state restoration when possible
-- **Partial Recovery**: Resume with warning when some data missing
-- **Graceful Degradation**: Restart phase with maximum retained context
-- **Manual Intervention**: Request user guidance for complex conflicts
+### Simple Recovery Strategy
+- **Phase Restart**: If unclear state, restart current phase
+- **User Confirmation**: Ask user to confirm resume point
+- **Minimal Recovery**: Restore basic session info only
 
-## Agent Integration Protocol
+## Simplified Agent Integration
 
-### Required Agent Capabilities
-All agents must support:
-- Checkpoint save/load functionality
-- State validation for resumption
-- Context preservation across interrupts
-- Progress reporting to session manager
+### Minimal Agent Requirements
+- Report task completion status
+- Update task JSON files
+- No complex checkpoint management needed
 
-### Phase-Specific Integration
-- **Planning Agents**: Auto-save planning outputs
-- **Implementation Agents**: Track code changes and test results
-- **Review Agents**: Preserve validation outcomes
+### Phase Integration
+- **Planning Agents**: Create planning documents
+- **Implementation Agents**: Update task status to completed
+- **Review Agents**: Mark review as complete
 
 ## Error Handling
 
 ### Common Scenarios
-1. **Session File Corruption**:
-   - Automatic backup before each save
-   - Rollback to last known good state
-   - Recovery from planning documents
+1. **Session File Missing**: Create new session file with defaults
+2. **Invalid Phase State**: Reset to last known valid phase  
+3. **Multi-Session Conflicts**: Auto-resolve by latest timestamp
 
-2. **Version Incompatibility**:
-   - Automatic migration for minor versions
-   - Manual intervention for major changes
-   - Backward compatibility for essential fields
+## Session Lifecycle
 
-3. **Missing Dependencies**:
-   - Graceful handling of missing files
-   - Regeneration of recoverable artifacts
-   - Clear error messages for resolution
+### Simple Lifecycle
+1. **Create**: Generate session ID and directory
+2. **Activate**: Set as current active session
+3. **Execute**: Track phase completion only  
+4. **Complete**: Mark as finished
 
-4. **Multi-Session Conflicts**:
-   - Registry integrity validation
-   - Active session collision detection
-   - Automatic session status correction
-
-## Session Lifecycle Management
-
-### Complete Session Lifecycle
-**1. Registration Phase**
-- Add session to global registry (`.workflow/session_status.jsonl`)
-- Generate unique session ID in WFS-[topic-slug] format
-- Create session directory structure
-
-**2. Activation Phase**  
-- Set session as active (deactivates any other active session)
-- Initialize session state file (`workflow-session.json`)
-- Create base directory structure based on complexity level
-
-**3. Execution Phase**
-- Track progress through workflow phases (PLAN → IMPLEMENT → REVIEW)
-- Maintain checkpoints at natural boundaries
-- Update session state with phase transitions and progress
-
-**4. State Management Phase**
-- **Active**: Session is currently being worked on
-- **Paused**: Session temporarily suspended, can be resumed
-- **Completed**: Session finished successfully
-
-**5. Session Operations**
-- **Switching**: Change active session (preserves state of previous)
-- **Resumption**: Intelligent recovery from saved state and checkpoints
-- **Interruption**: Graceful pause with complete state preservation
-
-### Session State Transitions
+### State Transitions
 ```
-INACTIVE → ACTIVE → PAUSED → ACTIVE → COMPLETED
-    ↑         ↓         ↓         ↑         ↓
-  CREATE    PAUSE    SWITCH    RESUME   ARCHIVE
+INACTIVE → ACTIVE → COMPLETED
+    ↑         ↓         ↓
+  CREATE    WORK    FINISH
 ```
 
 ## Implementation Guidelines
 
-### Session Management Operations
-
-### Testing Requirements
-- Single-phase interruption/resumption
-- Multi-phase workflow continuity
-- Context preservation validation
-- Error recovery scenarios
-- Multi-session registry operations
-- Session switching without data loss
-- Active session inheritance in commands
-- Registry integrity validation
-- Version migration testing
+### Key Principles
+- **Minimal State**: Only track essential information
+- **Phase-Level Updates**: Avoid frequent micro-updates
+- **Simple Recovery**: Basic session restoration only
+- **User Control**: Manual checkpoint requests
 
 ### Success Metrics
-- Zero data loss on resume or session switch
-- Context continuity maintained across sessions
-- No duplicate work performed
-- Full workflow completion capability
-- Seamless multi-session management
-- Registry integrity maintained
-- Commands automatically inherit active session context
-- Minimal performance overhead

 ## Overview
 
+This document defines simplified complexity classification and task hierarchy rules for the JSON-only workflow system.
 
-This document defines authoritative complexity thresholds, decomposition triggers, and decision trees for workflow complexity classification.
+## Simplified Complexity Classification
 
-## Standardized Complexity Thresholds
+### Simple Workflows
+**Criteria**: Direct implementation tasks with clear scope
+**Structure**: Single-level tasks (impl-N format)
+**Task Files**: impl-*.json only
+**Max Depth**: 1 level
 
-### Simple Workflows (<5 tasks)
-**Criteria**: Tasks < 5 AND modules ≤ 3 AND effort ≤ 4h
-**Structure**: Minimal structure with basic task tracking
-**Documents**: IMPL_PLAN.md only, no TODO_LIST.md
-**Task Files**: impl-*.json (single level)
+### Medium Workflows  
+**Criteria**: Feature implementation requiring task breakdown
+**Structure**: Two-level hierarchy (impl-N.M format)
+**Task Files**: Parent and child JSON files
+**Max Depth**: 2 levels
 
-### Medium Workflows (5-15 tasks)  
-**Criteria**: Tasks 5-15 OR modules > 3 OR effort > 4h OR complex dependencies
-**Structure**: Enhanced structure with progress tracking
-**Documents**: IMPL_PLAN.md + TODO_LIST.md (auto-triggered)
-**Task Files**: impl-*.*.json (up to 2 levels)
+### Complex Workflows
+**Criteria**: System-wide changes requiring detailed decomposition
+**Structure**: Three-level hierarchy (impl-N.M.P format)
+**Task Files**: Multi-level JSON hierarchy
+**Max Depth**: 3 levels (maximum allowed)
 
-### Complex Workflows (>15 tasks)
-**Criteria**: Tasks > 15 OR modules > 5 OR effort > 2 days OR multi-repository
-**Structure**: Complete structure with comprehensive documentation
-**Documents**: IMPL_PLAN.md + TODO_LIST.md + expanded documentation
-**Task Files**: impl-*.*.*.json (up to 3 levels maximum)
+## Task Hierarchy Rules
 
-## Complexity Decision Tree
+### Hierarchical ID Format
+- **Level 1**: impl-N (main tasks)
+- **Level 2**: impl-N.M (subtasks)  
+- **Level 3**: impl-N.M.P (detailed subtasks)
+- **Maximum**: 3 levels deep
 
-### Classification Algorithm
-```
-START: Analyze Workflow Requirements
-    ↓
-Count Tasks → Is Task Count < 5?
-    ↓ YES              ↓ NO
-Count Modules    Count Modules → > 5?
-    ↓                    ↓ YES
-≤ 3 Modules?        COMPLEX
-    ↓ YES              ↓ NO
-Estimate Effort   Estimate Effort → > 2 days?
-    ↓                    ↓ YES
-≤ 4 hours?         COMPLEX
-    ↓ YES              ↓ NO
-SIMPLE           Check Dependencies → Multi-repo?
-                       ↓ YES              ↓ NO
-                    COMPLEX           MEDIUM
+### Parent-Child Relationships
+```json
+// Parent task
+{
+  "id": "impl-1",
+  "title": "Build authentication module",
+  "status": "pending",
+  "relations": {
+    "parent": null,
+    "subtasks": ["impl-1.1", "impl-1.2"],
+    "dependencies": []
+  }
+}
+
+// Child task
+{
+  "id": "impl-1.1",
+  "title": "Design auth schema", 
+  "status": "pending",
+  "relations": {
+    "parent": "impl-1",
+    "subtasks": [],
+    "dependencies": []
+  }
+}
 ```
 
-### Decision Matrix
+## Decomposition Triggers
 
-| **Factor** | **Simple** | **Medium** | **Complex** |
-|------------|------------|------------|-------------|
-| Task Count | < 5 | 5-15 | > 15 |
-| Module Count | ≤ 3 | 4-5 | > 5 |
-| Effort Estimate | ≤ 4h | 4h-2d | > 2d |
-| Dependencies | Simple | Complex | Multi-repo |
-| Repository Scope | Single | Single | Multiple |
+### Automatic Decomposition When:
+- Task title indicates multiple distinct activities
+- Implementation scope spans multiple modules
+- Clear sub-components can be identified
+- Task complexity exceeds single-agent execution
 
-### Threshold Priority
-1. **Task Count**: Primary factor (most reliable predictor)
-2. **Module Count**: Secondary factor (scope indicator)
-3. **Effort Estimate**: Tertiary factor (complexity indicator)
-4. **Dependencies**: Override factor (can force higher complexity)
+### Skip Decomposition For:
+- Single file modifications
+- Simple bug fixes
+- Clear, atomic tasks
+- Documentation updates
 
-## Automatic Document Generation Rules
-
-### Generation Matrix
-| **Complexity** | **IMPL_PLAN.md** | **TODO_LIST.md** | **Task Hierarchy** | **Structure** |
-|----------------|------------------|------------------|-------------------|---------------|
-| Simple | Always | No | 1 level | Minimal |
-| Medium | Always | Auto-trigger | 2 levels | Enhanced |
-| Complex | Always | Always | 3 levels | Complete |
-
-### Auto-trigger Conditions
-**TODO_LIST.md Generation** (Medium workflows):
-- Tasks ≥ 5 OR modules > 3 OR effort > 4h OR dependencies complex
-
-**Enhanced Structure** (Medium workflows):
-- Progress tracking with hierarchical task breakdown
-- Cross-references between planning and implementation
-- Summary generation for major tasks
-
-**Complete Structure** (Complex workflows):
-- Comprehensive documentation suite
-- Multi-level task decomposition
-- Full progress monitoring and audit trail
-
-## Task System Integration
-
-### Hierarchical Task Schema
-**Maximum Depth**: 3 levels (impl-N.M.P)
-**Task File Structure**: Complexity determines maximum hierarchy depth
-
-### Progress Calculation Rules
-**Simple**: Linear progress through main tasks
-**Medium**: Weighted progress with subtask consideration  
-**Complex**: Hierarchical progress with multi-level rollup
-
-## Implementation Integration Rules
-
-### Decomposition Triggers
-**Automatic Decomposition Required When**:
-- Task count exceeds complexity threshold (5+ for medium, 15+ for complex)
-- Cross-module changes affect >3 modules
-- Architecture pattern changes required
-- Multi-repository impacts detected
-- Complex interdependencies identified
-
-### Direct Execution Conditions
-**Skip Decomposition For**:
-- Single module updates with clear boundaries
-- Simple documentation changes  
-- Isolated bug fixes affecting <3 files
-- Clear, well-defined maintenance tasks
+## Task Status Rules
 
+### Container Task Rules
+- Parent tasks become "container" status when broken down
+- Cannot be directly executed (must execute subtasks)
+- Status derived from subtask completion
 
+### Leaf Task Rules
+- Only leaf tasks can be executed directly
+- Status reflects actual execution state
+- Progress tracked at leaf level only
 
 ## Validation Rules
 
-### Complexity Classification Validation
-1. **Threshold Verification**: Ensure task count, module count, and effort estimates align
-2. **Override Checks**: Verify dependency complexity doesn't require higher classification  
-3. **Consistency Validation**: Confirm file structure matches complexity level
-4. **Progress Calculation**: Validate progress tracking matches hierarchy depth
+### Hierarchy Validation
+1. **Depth Limit**: Maximum 3 levels (impl-N.M.P)
+2. **ID Format**: Must follow hierarchical naming
+3. **Parent References**: All parent IDs must exist
+4. **Circular Dependencies**: Not allowed in hierarchy
 
-### Quality Assurance
-- Decomposition depth must not exceed 3 levels (impl-N.M.P maximum)
-- Task hierarchy must be consistent across JSON files and TODO_LIST.md
-- Complexity classification must align with document generation rules
-- Auto-trigger conditions must be properly evaluated and documented
+### Task Integrity
+- All referenced tasks must exist as JSON files
+- Parent-child relationships must be bidirectional
+- Container tasks cannot have "completed" status until all children complete
+- Leaf tasks must have valid execution status

-
-## Unified Task JSON Schema
+## Simplified Task JSON Schema
 
 ### Core Task Structure
-All task files must conform to this schema with support for recursive decomposition:
+All task files use this simplified 8-field schema:

   }
 }
 ```
 
-### Status Enumeration
-Standard status values across all systems:
+### Status Values
 - **pending**: Task created but not started
-- **active**: Task currently being worked on
+- **active**: Task currently being worked on  
 - **completed**: Task successfully finished
 - **blocked**: Task cannot proceed due to dependencies
-- **failed**: Task attempted but failed execution
+- **container**: Parent task with subtasks (not directly executable)
 
-### Type Classification
-Standard task types:
+### Task Types
 - **feature**: New functionality implementation
 - **bugfix**: Fixing existing issues
 - **refactor**: Code improvement without functionality change
 - **test**: Test implementation or testing tasks
 - **docs**: Documentation creation or updates
 
-### Priority Levels
-Standard priority values:
-- **low**: Can be deferred
-- **normal**: Standard priority (default)
-- **high**: Should be completed soon
-- **critical**: Must be completed immediately
+## Context Management
 
-## TodoWrite Integration System
+### Context Structure
+Context provides complete information for agent execution:
 
-### TodoWrite Tool vs TODO_LIST.md File
-**Clear Distinction**: TodoWrite is Claude's internal task tracking tool, TODO_LIST.md is the persistent workflow file
+- **requirements**: Specific functional requirements
+- **scope**: File patterns and modules affected  
+- **acceptance**: Success criteria and completion definition
+- **inherited_from**: Source workflow or parent task
 
-**TodoWrite Tool**:
-- Claude's internal task management interface
-- Real-time progress tracking during execution
-- Temporary state for active workflow sessions
-- Used by agents and commands for immediate task coordination
+### Context Inheritance
+- **Workflow → Task**: Global requirements and constraints
+- **Parent → Subtask**: Refined scope and specific requirements
+- **Context Preservation**: All fields maintained for agent execution
 
-**TODO_LIST.md File**:
-- Persistent task list stored in workflow session directory
-- Cross-referenced with JSON task files
-- Maintains task hierarchy and progress visualization
-- Provides audit trail and resumable task state
+## Task Relationships
 
-### Synchronization Protocol
-
-**TodoWrite → TODO_LIST.md**:
-- TodoWrite task completion triggers TODO_LIST.md checkbox updates
-- TodoWrite progress reflected in TODO_LIST.md progress calculations
-- TodoWrite task status changes sync to JSON task files
-
-**TODO_LIST.md → JSON Task Files**:
-- Checkbox changes in TODO_LIST.md update JSON task status
-- Manual task modifications propagate to JSON files
-- Progress calculations derived from JSON task completion
-
-**JSON Task Files → TodoWrite**:
-- Task creation in JSON automatically creates TodoWrite entries when session is active
-- JSON status changes reflect in TodoWrite display
-- Agent task assignments sync to TodoWrite coordination
-
-### Integration Rules
-1. **Session Active**: TodoWrite automatically syncs with TODO_LIST.md
-2. **Session Paused**: TodoWrite state preserved in TODO_LIST.md
-3. **Session Resumed**: TodoWrite reconstructed from TODO_LIST.md and JSON files
-4. **Cross-Session**: TODO_LIST.md provides continuity, TodoWrite provides active session interface
-
-## Workflow Integration Schema
-
-### Workflow Task Summary
-Workflow session contains minimal task references with hierarchical support:
-
-```json
-{
-  "phases": {
-    "IMPLEMENT": {
-      "tasks": ["impl-1", "impl-2", "impl-3"],
-      "completed_tasks": ["impl-1"],
-      "blocked_tasks": [],
-      "progress": 33,
-      "task_depth": 2,
-      "last_sync": "2025-09-05T13:15:00Z"
-    }
-  }
-}
-```
-
-### Task Reference Format
-Tasks referenced by hierarchical ID, full details in JSON files:
-
-```json
-{
-  "task_summary": {
-    "id": "impl-1",
-    "parent_id": null,
-    "title": "Task title",
-    "status": "completed",
-    "type": "feature",
-    "depth": 1,
-    "progress": 100
-  }
-}
-
-// Subtask example
-{
-  "task_summary": {
-    "id": "impl-1.2.1",
-    "parent_id": "impl-1.2",
-    "title": "Detailed subtask",
-    "status": "active",
-    "type": "implementation",
-    "depth": 3,
-    "progress": 45
-  }
-}
-```
-
-## Data Ownership Rules
-
-### JSON Task Files Own
-- Complete task details and context (all levels)
-- Execution history and checkpoints
-- Parent-child relationships (via parent_id)
-- Requirements and acceptance criteria
-- Agent assignment and progress tracking
-- Hierarchical decomposition state
-
-### Workflow Session Owns
-- Top-level task ID lists per phase
-- Overall progress calculations
-- Phase transition triggers  
-- Global context inheritance rules
-- Task depth management (max 3 levels)
-- Sync timestamps and validation
-
-### Shared Responsibility
-- Task status (JSON authoritative, TODO_LIST.md displays)
-- Progress calculations (derived from JSON, shown in TODO_LIST.md)
-- Hierarchical relationships (JSON defines, TODO_LIST.md visualizes)
-- Dependency validation (cross-file consistency)
-
-## Synchronization Principles
-
-### Automatic Sync Triggers
-- **Task Creation**: Add to workflow task list and TODO_LIST.md
-- **Status Change**: Update TODO_LIST.md checkboxes and progress
-- **Task Completion**: Update TODO_LIST.md and recalculate hierarchy progress
-- **Task Decomposition**: Create child JSON files, update TODO_LIST.md structure
-- **Context Update**: Propagate to child tasks in hierarchy
-- **Dependency Change**: Validate across all hierarchy levels
-
-### Sync Direction Rules
-1. **JSON Task → TODO_LIST.md**: Status updates, progress changes, completion
-2. **JSON Task → Workflow**: Task creation, hierarchy changes, phase completion
-3. **IMPL_PLAN.md → JSON Task**: Context updates, requirement changes
-4. **TODO_LIST.md → JSON Task**: Manual status changes via checkboxes
-5. **Bidirectional**: Dependencies, timestamps, hierarchy validation
-
-### Conflict Resolution
-Priority order for conflicts:
-1. **Most Recent**: Latest timestamp wins
-2. **Task Authority**: Task files authoritative for task details
-3. **Workflow Authority**: Workflow authoritative for phase management
-4. **Manual Resolution**: User confirmation for complex conflicts
-
-### Data Integrity Checks
-- **ID Consistency**: All task IDs exist across JSON files and TODO_LIST.md
-- **Hierarchy Validation**: Parent-child relationships are bidirectional and valid
-- **Depth Limits**: No task exceeds 3 levels deep (impl-N.M.P max)
-- **Status Validation**: Status values match enumeration across all files
-- **Dependency Validation**: All dependencies exist and respect hierarchy
-- **Progress Accuracy**: Calculated progress matches hierarchical task completion
-- **Timestamp Ordering**: Created ≤ Started ≤ Completed across hierarchy
-
-## Hierarchical Task Decomposition
-
-### Decomposition Rules
-**Maximum Depth**: 3 levels (impl-N.M.P)
-- **Level 1** (impl-N): Main implementation tasks
-- **Level 2** (impl-N.M): Subtasks with specific focus areas  
-- **Level 3** (impl-N.M.P): Detailed implementation steps
+### Hierarchical Structure
+- **Parent-Child**: Uses `relations.parent` and `relations.subtasks`
+- **Dependencies**: Uses `relations.dependencies` for task ordering
+- **Maximum Depth**: 3 levels (impl-N.M.P format)
 
 ### ID Format Standards
 ```
 impl-1              # Main task
-impl-1.1            # Subtask of impl-1
+impl-1.1            # Subtask of impl-1  
 impl-1.1.1          # Detailed subtask of impl-1.1
-impl-1.2            # Another subtask of impl-1
-impl-2              # Another main task
 ```
 
-### Parent-Child Relationships
-```json
-// Parent task (impl-1.json)
-{
-  "id": "impl-1",
-  "parent_id": null,
-  "subtasks": ["impl-1.1", "impl-1.2", "impl-1.3"]
-}
-
-// Child task (impl-1.1.json)  
-{
-  "id": "impl-1.1",
-  "parent_id": "impl-1",
-  "subtasks": ["impl-1.1.1", "impl-1.1.2"]
-}
-
-// Grandchild task (impl-1.1.1.json)
-{
-  "id": "impl-1.1.1", 
-  "parent_id": "impl-1.1",
-  "subtasks": []  // Leaf node - no further decomposition
-}
-```
-
-### Progress Calculation
-- **Leaf tasks**: Progress based on execution checkpoints
-- **Container tasks**: Progress = average of all subtask progress
-- **Workflow progress**: Weighted average of all top-level tasks
-
-### Status Propagation Rules
-- **Child → Parent**: Parent cannot be "completed" until all children complete
-- **Parent → Child**: Parent "blocked" status may propagate to children
-- **Sibling Independence**: Subtasks at same level operate independently
-
-## Context Management
-
-### Context Inheritance Chain
-```
-Workflow Context
-    ↓ (inherits requirements, constraints)
-Task Context
-    ↓ (distributes scope, specific requirements)
-Subtask Context
-```
-
-### Context Distribution Rules
-- **Requirements**: Flow from workflow to tasks
-- **Scope**: Refined at each level (workflow → task → subtask)
-- **Constraints**: Apply globally from workflow
-- **Acceptance Criteria**: Specific to each task level
-
-### Dynamic Context Updates
-- Changes in workflow context propagate to tasks
-- Task-specific context remains isolated
-- Subtask context inherits from parent task
-- Context versioning tracks changes
-
 ## Agent Integration
 
-### Agent Assignment Logic
-Based on task type and complexity:
+### Agent Assignment
+Based on task type and title keywords:
 - **Planning tasks** → planning-agent
-- **Implementation** → code-developer
+- **Implementation** → code-developer  
 - **Testing** → test-agent
 - **Documentation** → docs-agent
 - **Review** → review-agent
 
-### Execution Context Preparation
+### Execution Context
+Agents receive complete task JSON plus workflow context:
 ```json
 {
-  "execution_context": {
-    "task": {
-      "id": "IMPL-001",
-      "requirements": ["from task context"],
-      "scope": ["from task context"]
-    },
-    "workflow": {
-      "session": "WFS-2025-001",
-      "phase": "IMPLEMENT",
-      "global_context": ["from workflow"]
-    },
-    "agent": {
-      "type": "code-developer",
-      "capabilities": ["coding", "testing"],
-      "context_optimizations": ["code_patterns"]
-    }
+  "task": { /* complete task JSON */ },
+  "workflow": {
+    "session": "WFS-user-auth",
+    "phase": "IMPLEMENT"
   }
 }
 ```
 
+## File Organization
+
+### JSON Task Files
+**Location**: `.task/impl-[id].json`
+**Naming**: Follows hierarchical ID format
+**Content**: Complete task definition
+
+### Single Source of Truth
+- JSON files contain all task data
+- No document synchronization needed
+- Views generated on-demand from JSON only
+
+## Validation Rules
+
+### Task Integrity
+1. **ID Uniqueness**: All task IDs must be unique
+2. **Hierarchical Format**: Must follow impl-N[.M[.P]] pattern
+3. **Parent References**: All parent IDs must exist as JSON files
+4. **Depth Limits**: Maximum 3 levels deep
+5. **Status Consistency**: Status values from defined enumeration
+6. **Required Fields**: All 8 core fields must be present
+
+### Relationship Validation  
+- Parent-child relationships must be bidirectional
+- Dependencies must reference existing tasks
+- Container tasks cannot be completed until all subtasks complete
+- No circular dependencies allowed

 ## Error Handling
 
-### Common Error Scenarios
-1. **JSON Task File Missing**: Recreate from TODO_LIST.md or parent task data
-2. **Status Mismatch**: JSON files are authoritative, update TODO_LIST.md
-3. **Hierarchy Broken**: Reconstruct parent-child relationships from IDs
-4. **Invalid Dependencies**: Validate across all hierarchy levels
-5. **Schema Version Mismatch**: Migrate to current hierarchical schema
-6. **Orphaned Tasks**: Clean up or reassign to proper parent/workflow
-7. **Depth Violation**: Flatten excessive hierarchy to 3 levels max
+### Common Scenarios
+1. **Missing JSON File**: Indicates broken reference - must repair
+2. **Invalid Status**: Update to valid status value
+3. **Broken Hierarchy**: Reconstruct parent-child relationships  
+4. **Orphaned Task**: Reassign to proper parent or workflow
 
-### Recovery Strategies

-### Integration Architecture
-```
-TodoWrite Tool (Claude Internal)
-    ↕ Real-time sync
-TODO_LIST.md (Workflow Persistence)  
-    ↕ Bidirectional updates
-JSON Task Files (Detailed State)
-    ↕ Status propagation
-Workflow Session (Master State)
-```
-
-## Mandatory TodoWrite Creation
-
-### Pre-execution Requirements
-Every workflow execution MUST create TodoWrite entries before agent coordination begins.
-
-**Workflow Initialization**:
-1. Analyze workflow complexity 
-2. Create appropriate TodoWrite pattern based on complexity
-3. Initialize TODO_LIST.md file if complexity warrants it
-4. Begin agent coordination with TodoWrite context
-
-### Agent Handoff Protocol
-**Agent → TodoWrite**:
-- Agents receive TodoWrite context on initialization
-- Agents update todo status in real-time during execution
-- Agents mark completion only when truly finished
-- Agents create new todos when discovering additional work
-
-## TodoWrite Patterns by Complexity
-
-### Simple Workflows (3-4 todos)
-**Pattern**: Linear execution with minimal tracking
-```
-1. [pending] Context gathering
-2. [pending] Solution implementation  
-3. [pending] Code review and validation
-4. [pending] Task completion
-```
-
-**Coordination**: Direct TodoWrite → JSON files (no TODO_LIST.md)
-
-### Medium Workflows (5-7 todos)
-**Pattern**: Structured execution with progress tracking
-```
-1. [pending] Implementation planning
-2. [pending] Context gathering
-3. [pending] Implementation with testing
-4. [pending] Functionality validation
-5. [pending] Code quality review
-6. [pending] Task completion
-```
-
-**Coordination**: TodoWrite ↔ TODO_LIST.md ↔ JSON files
-
-### Complex Workflows (7-10 todos)
-**Pattern**: Comprehensive execution with full documentation
-```
-1. [pending] Detailed planning
-2. [pending] Documentation generation
-3. [pending] Context and dependency gathering
-4. [pending] Comprehensive implementation
-5. [pending] Acceptance criteria validation
-6. [pending] Thorough review process
-7. [pending] Feedback iteration
-8. [pending] Task completion
-```
-
-**Coordination**: Full three-way sync with audit trails
-
-## Synchronization Protocols
-
-### TodoWrite → TODO_LIST.md Sync
-**Trigger Events**:
-- Todo status change (pending → active → completed)
-- Todo creation during workflow execution
-- Todo blocking/unblocking status changes
-- Progress milestone achievement
-
-**Sync Actions**:
-- Update TODO_LIST.md checkbox states
-- Recalculate progress percentages
-- Update task status summaries
-- Propagate completion timestamps
-
-### TODO_LIST.md → TodoWrite Sync
-**Trigger Events**:
-- Manual checkbox modification in TODO_LIST.md
-- External task status updates
-- Workflow resumption from paused state
-- Cross-session task inheritance
-
-**Sync Actions**:
-- Reconstruct TodoWrite state from TODO_LIST.md
-- Initialize appropriate todo patterns
-- Restore progress tracking context
-- Re-establish agent coordination context
-
-### Bidirectional JSON Integration
-**TodoWrite → JSON**:
-- Task completion triggers JSON status updates
-- Progress checkpoints sync to JSON execution state
-- Agent assignments propagate to JSON context
-
-**JSON → TodoWrite**:
-- JSON task creation generates TodoWrite entries
-- JSON status changes reflect in TodoWrite display
-- JSON dependency updates trigger TodoWrite coordination
-
-## State Management Rules
-
-### Session Lifecycle Integration
-**Active Session**:
-- TodoWrite automatically syncs with workflow session
-- Real-time updates propagate to persistent files
-- Progress tracking maintains workflow continuity
-
-**Session Pause**:
-- TodoWrite state preserved in TODO_LIST.md
-- JSON files maintain detailed task context
-- Workflow session tracks overall progress
-
-**Session Resume**:
-- TodoWrite reconstructed from TODO_LIST.md + JSON files
-- Previous progress state fully restored
-- Agent context re-established from preserved state
-
-**Session Switch**:
-- Current TodoWrite state saved to workflow files
-- New session TodoWrite initialized from target session files
-- Seamless context switching without data loss
-
-### Progress Calculation Rules
-**Simple Workflows**: Progress = completed todos / total todos
-**Medium Workflows**: Progress = weighted completion across todo + subtask hierarchy
-**Complex Workflows**: Progress = multi-level rollup with checkpoint weighting
-
-### Blocking and Dependency Management
-**Todo Blocking**:
-- Blocked todos tracked with resolution requirements
-- Upstream dependencies prevent todo activation
-- Dependency resolution automatically unblocks downstream todos
-
-**Cross-Todo Dependencies**:
-- TodoWrite enforces dependency order
-- JSON files maintain dependency graph
-- TODO_LIST.md visualizes dependency relationships
-
-## Error Handling and Recovery
-
-### TodoWrite State Corruption
-**Recovery Strategy**:
-1. Attempt to reconstruct from TODO_LIST.md
-2. Fallback to JSON file task status
-3. Last resort: regenerate from workflow session state
-4. Manual intervention if all sources inconsistent
-
-### Sync Conflict Resolution
-**Priority Order**:
-1. **TodoWrite** (most recent user interaction)
-2. **JSON Files** (authoritative task state)
-3. **TODO_LIST.md** (persistence layer)
-4. **Manual Resolution** (complex conflicts)
-
-### Validation Rules
-- Todo IDs must map to valid JSON task IDs
-- Todo status must be consistent across all coordination layers
-- Progress calculations must align with actual task completion
-- Single active todo rule must be enforced at all times
-
-## Integration with Specialized Systems
-
-### Task Management Integration
-
-**Hierarchical Support**: TodoWrite flattens task hierarchy for execution view
-**Status Synchronization**: Bidirectional sync with JSON task status
-
-### Session Management Integration  
-**Multi-Session Support**: TodoWrite aware of active session context
-**Context Switching**: Seamless integration with session switching
-
-### Complexity Classification Integration
-**Pattern Selection**: TodoWrite patterns match complexity classification
-**Auto-scaling**: TodoWrite patterns adapt to workflow complexity changes
-
-## Quality Assurance
-
-### Mandatory Validation Checks
-- TodoWrite entries exist before agent coordination
-- Single active todo rule maintained throughout execution
-- Progress tracking accuracy across all coordination layers
-- Completion gates properly validated before marking tasks complete
-- Sync consistency across TodoWrite, TODO_LIST.md, and JSON files
-
-### Performance Requirements
-- TodoWrite updates must be real-time (< 100ms response)
-- Sync operations must complete within 500ms
-- Progress calculation must be immediate
-- Context switching must preserve full state
