+# Incremental Feature Build Command
+
+Systematic approach for building complex features incrementally, preventing premature completion and ensuring comprehensive functionality through structured feature tracking.
+
+## Instructions
+
+Build a feature incrementally using the structured approach for: **$ARGUMENTS**
+
+This command implements best practices for long-running agent tasks, preventing the tendency to one-shot applications or prematurely consider projects complete.
+
+> **Note:** `$ARGUMENTS` is automatically replaced with the text following the command invocation.
+> Example: `/dev:incremental-feature-build user authentication system` sets `$ARGUMENTS` to "user authentication system"
+
+---
+
+## Phase 1: Feature Requirements Expansion
+
+### 1.1 Create Feature Tracking Directory
+
+```bash
+# Create tracking directory with error handling
+mkdir -p .feature-tracking || { echo "ERROR: Cannot create .feature-tracking directory. Check permissions."; exit 1; }
+```
+
+If directory creation fails, verify:
+- You have write permissions in the current directory
+- Sufficient disk space is available
+- No file named `.feature-tracking` already exists
+
+### 1.2 Generate Comprehensive Feature List
+
+Analyze the user's request and expand it into a comprehensive list of granular features. Each feature should be a discrete, testable unit of functionality.
+
+**Create file: `.feature-tracking/features.json`**
+
+```json
+{
+  "project": "$ARGUMENTS",
+  "created": "YYYY-MM-DD",
+  "version": "1.0.0",
+  "summary": {
+    "total": 0,
+    "passing": 0,
+    "failing": 0
+  },
+  "features": []
+}
+```
+
+### 1.3 Feature Schema
+
+Each feature MUST follow this exact JSON schema:
+
+```json
+{
+  "id": "FEAT-001",
+  "category": "functional|ui|integration|performance|security|accessibility",
+  "priority": "critical|high|medium|low",
+  "description": "Clear, actionable description of the feature",
+  "steps": [
+    "Step 1: Specific action to verify",
+    "Step 2: Expected behavior check",
+    "Step 3: Edge case validation"
+  ],
+  "dependencies": ["FEAT-000"],
+  "passes": false,
+  "implementedAt": null,
+  "commitHash": null
+}
+```
+
+> **Note:** This command uses a simple boolean `passes` field since features are implemented sequentially.
+> The parallel command (`/dev:parallel-feature-build`) uses a multi-state `status` field to track
+> concurrent work: `pending`, `in_progress`, `passed`, `blocked`.
+
+### 1.4 Feature Categories
+
+Generate features across ALL relevant categories:
+
+| Category | Description | Examples |
+|----------|-------------|----------|
+| `functional` | Core business logic | User can submit form, data saves correctly |
+| `ui` | User interface elements | Button displays, modal opens, responsive layout |
+| `integration` | System connections | API calls work, database syncs, auth flows |
+| `performance` | Speed and efficiency | Page loads under 3s, lazy loading works |
+| `security` | Protection measures | Input sanitized, auth required, CSRF protection |
+| `accessibility` | Inclusive design | Screen reader support, keyboard navigation |
+
+### 1.5 Feature Generation Guidelines
+
+When expanding the user's request:
+
+1. **Use Hierarchical Organization**: Group features into epics/modules for manageability
+   - Small projects: 10-30 features
+   - Medium projects: 30-60 features
+   - Large projects: 60-100 features (consider using `/dev:parallel-feature-build` instead)
+2. **Be Specific**: Each feature should be independently verifiable
+3. **Include Edge Cases**: Error states, empty states, boundary conditions
+4. **Cover All Paths**: Happy path AND unhappy paths
+5. **Think Like a User**: What would they expect at each step?
+
+**Feature Grouping Example:**
+```json
+{
+  "epics": [
+    {
+      "id": "EPIC-01",
+      "name": "User Authentication",
+      "features": ["FEAT-001", "FEAT-002", "FEAT-003"]
+    }
+  ]
+}
+```
+
+---
+
+## Phase 2: Initialize Progress Tracking
+
+### 2.1 Create Progress File
+
+**Create file: `.feature-tracking/PROGRESS.md`**
+
+```markdown
+# Feature Implementation Progress
+
+## Project: $ARGUMENTS
+## Started: YYYY-MM-DD
+
+---
+
+## Current Status
+
+- **Features Total**: X
+- **Implemented**: 0
+- **Remaining**: X
+
+---
+
+## Session Log
+
+### Session 1 - YYYY-MM-DD
+
+**Focus**: Initial setup and first features
+
+**Completed**:
+- (none yet)
+
+**Notes**:
+- (session notes here)
+
+**Commit**: (hash when committed)
+
+---
+
+## Implementation Order
+
+Based on dependencies, implement in this order:
+
+1. [ ] FEAT-001 - Description
+2. [ ] FEAT-002 - Description
+...
+
+---
+
+## Blocked/Issues
+
+(Track any blockers here)
+```
+
+### 2.2 Git Initialization Check
+
+Ensure git is initialized and create initial tracking commit:
+
+```bash
+git add .feature-tracking/
+git commit -m "feat: initialize feature tracking for $ARGUMENTS
+
+- Created features.json with X features to implement
+- All features marked as failing (passes: false)
+- Created progress tracking file"
+```
+
+---
+
+## Phase 3: Incremental Implementation
+
+### CRITICAL RULES
+
+**You MUST follow these rules without exception:**
+
+1. **ONE FEATURE AT A TIME**: Never work on multiple features simultaneously
+2. **NO TEST REMOVAL**: It is **UNACCEPTABLE** to remove or edit features from features.json because this could lead to missing or buggy functionality
+3. **ONLY CHANGE STATUS**: The only modification allowed to features.json is changing `passes` from `false` to `true` and updating `implementedAt` and `commitHash`
+4. **COMMIT AFTER EACH**: Create a git commit after each feature is implemented
+5. **CLEAN STATE**: Each commit must leave the codebase in a working state
+
+### 3.1 Feature Implementation Loop
+
+For each feature, follow this exact workflow:
+
+#### Step A: Select Next Feature
+
+1. Read `.feature-tracking/features.json`
+2. Find the first feature where `passes: false`
+3. Check dependencies are satisfied (all dependent features pass)
+4. Announce: "Now implementing FEAT-XXX: [description]"
+
+#### Step B: Implement Feature
+
+1. Write the necessary code
+2. Ensure existing functionality still works
+3. Test the specific feature manually or with tests
+4. Verify all steps in the feature definition
+
+#### Step C: Update Tracking (JSON Only)
+
+Edit `.feature-tracking/features.json`:
+- Change `"passes": false` to `"passes": true`
+- Set `"implementedAt": "YYYY-MM-DD HH:MM"`
+- Update summary counts
+
+```json
+{
+  "id": "FEAT-001",
+  "passes": true,
+  "implementedAt": "2024-01-15 14:30",
+  "commitHash": "(to be filled)"
+}
+```
+
+#### Step D: Commit Progress
+
+```bash
+git add .
+git commit -m "feat(FEAT-XXX): [brief description]
+
+Implemented: [feature description]
+
+Verification:
+- [step 1 verified]
+- [step 2 verified]
+- [step 3 verified]
+
+Progress: X/Y features complete"
+```
+
+#### Step E: Update Progress File
+
+Add to `.feature-tracking/PROGRESS.md`:
+
+```markdown
+### FEAT-XXX - [Description]
+- **Status**: PASSED
+- **Implemented**: YYYY-MM-DD HH:MM
+- **Commit**: [hash]
+- **Notes**: [any implementation notes]
+```
+
+#### Step F: Update Commit Hash
+
+Edit features.json to add the commit hash from Step D.
+
+### 3.2 Continue Until Complete
+
+Repeat the implementation loop until ALL features show `passes: true`.
+
+---
+
+## Phase 4: Recovery Protocols
+
+### 4.1 If Implementation Fails
+
+If a feature cannot be implemented correctly:
+
+1. **DO NOT** mark it as passing
+2. **DO NOT** remove the feature
+3. **DO** use git to revert changes: `git restore [files]`
+4. **DO** document the blocker in PROGRESS.md
+5. **DO** move to the next non-blocked feature
+
+### 4.2 If Code Breaks
+
+If implementing a feature breaks existing functionality:
+
+1. Run `git diff` to see changes
+2. Run `git stash` to save work
+3. Verify baseline still works
+4. Run `git stash pop` and fix carefully
+5. Or `git restore .` to fully reset working directory
+
+### 4.3 Revert Bad Commits
+
+If a commit introduced bugs:
+
+```bash
+git log --oneline -10  # Find the bad commit
+git revert [hash]      # Create revert commit
+```
+
+---
+
+## Phase 5: Completion Verification
+
+### 5.1 Final Checklist
+
+Before declaring the project complete:
+
+```bash
+# Generate completion report - count remaining incomplete features
+cat .feature-tracking/features.json | jq '[.features[] | select(.passes == false)] | length'
+# Must return 0
+
+# Or list any incomplete features for review
+cat .feature-tracking/features.json | jq '.features[] | select(.passes == false) | {id, description}'
+```
+
+**Must return 0** - all features must pass.
+
+### 5.2 Summary Generation
+
+Create final summary in PROGRESS.md:
+
+```markdown
+## Project Complete
+
+- **Total Features**: X
+- **All Passing**: Yes
+- **Total Commits**: Y
+- **Duration**: Z days/hours
+
+### Feature Breakdown by Category
+
+| Category | Count | Status |
+|----------|-------|--------|
+| functional | X | All Pass |
+| ui | X | All Pass |
+| integration | X | All Pass |
+| ... | ... | ... |
+```
+
+### 5.3 Final Commit
+
+```bash
+git add .
+git commit -m "feat: complete $ARGUMENTS implementation
+
+All X features implemented and verified:
+- functional: X/X passing
+- ui: X/X passing
+- integration: X/X passing
+- [other categories]
+
+See .feature-tracking/features.json for full details"
+```
+
+---
+
+## Example Feature Expansion
+
+For a request like "Build a todo app", expand to features like:
+
+```json
+{
+  "features": [
+    {
+      "id": "FEAT-001",
+      "category": "ui",
+      "priority": "critical",
+      "description": "App displays main todo list container on page load",
+      "steps": [
+        "Navigate to app URL",
+        "Verify todo container element exists",
+        "Check container is visible and centered"
+      ],
+      "dependencies": [],
+      "passes": false
+    },
+    {
+      "id": "FEAT-002",
+      "category": "functional",
+      "priority": "critical",
+      "description": "User can add a new todo item",
+      "steps": [
+        "Locate input field for new todo",
+        "Type 'Buy groceries' and press Enter",
+        "Verify new todo appears in list",
+        "Verify input field is cleared"
+      ],
+      "dependencies": ["FEAT-001"],
+      "passes": false
+    },
+    {
+      "id": "FEAT-003",
+      "category": "functional",
+      "priority": "critical",
+      "description": "User can mark todo as complete",
+      "steps": [
+        "Click checkbox next to existing todo",
+        "Verify checkbox shows checked state",
+        "Verify todo text shows strikethrough style"
+      ],
+      "dependencies": ["FEAT-002"],
+      "passes": false
+    }
+  ]
+}
+```
+
+---
+
+## Usage Examples
+
+### Start New Feature Build
+```
+/dev:incremental-feature-build user authentication system with OAuth
+```
+
+### Resume Existing Build
+```
+/dev:incremental-feature-build (continuing from features.json)
+```
+
+### View Progress
+```bash
+cat .feature-tracking/PROGRESS.md
+cat .feature-tracking/features.json | jq '.summary'
+```
+
+---
+
+## Key Principles
+
+1. **JSON Over Markdown**: Use JSON for feature tracking because models are less likely to inappropriately modify structured data
+2. **Atomic Progress**: Each commit represents one verified feature
+3. **Git as Safety Net**: Commit frequently to enable easy rollbacks
+4. **No Shortcuts**: Every feature must be individually verified
+5. **Clean States Only**: Never leave the codebase in a broken state

+# Parallel Feature Build Command
+
+Orchestrated parallel implementation of complex features using multiple agents, with dependency-aware batching and synchronized progress tracking.
+
+## Instructions
+
+Build features in parallel using agent orchestration for: **$ARGUMENTS**
+
+This command extends the incremental approach with parallel execution capabilities, launching multiple agents to work on independent features simultaneously while maintaining strict tracking and clean merge protocols.
+
+> **Note:** `$ARGUMENTS` is automatically replaced with the text following the command invocation.
+> Example: `/dev:parallel-feature-build e-commerce checkout` sets `$ARGUMENTS` to "e-commerce checkout"
+
+---
+
+## Phase 1: Feature Requirements & Dependency Analysis
+
+### 1.1 Create Feature Tracking Directory
+
+```bash
+# Create tracking directories with error handling
+mkdir -p .feature-tracking/{agents,batches,merges} || { echo "ERROR: Cannot create directories. Check permissions."; exit 1; }
+```
+
+If directory creation fails, verify:
+- You have write permissions in the current directory
+- Sufficient disk space is available
+
+### 1.2 Generate Comprehensive Feature List
+
+Same as incremental approach - expand user request into granular features.
+
+**Create file: `.feature-tracking/features.json`**
+
+```json
+{
+  "project": "$ARGUMENTS",
+  "created": "YYYY-MM-DD",
+  "version": "1.0.0",
+  "mode": "parallel",
+  "summary": {
+    "total": 0,
+    "passing": 0,
+    "failing": 0,
+    "in_progress": 0
+  },
+  "agents": {
+    "max_parallel": 4,
+    "active": []
+  },
+  "features": []
+}
+```
+
+### 1.3 Enhanced Feature Schema for Parallel Execution
+
+```json
+{
+  "id": "FEAT-001",
+  "category": "functional|ui|integration|performance|security|accessibility",
+  "priority": "critical|high|medium|low",
+  "description": "Clear, actionable description",
+  "steps": ["Step 1", "Step 2", "Step 3"],
+  "dependencies": ["FEAT-000"],
+  "dependents": ["FEAT-002", "FEAT-003"],
+  "status": "pending|in_progress|passed|blocked",
+  "assignedAgent": null,
+  "branch": null,
+  "batch": null,
+  "implementedAt": null,
+  "mergedAt": null,
+  "commitHash": null
+}
+```
+
+### 1.4 Build Dependency Graph
+
+**Create file: `.feature-tracking/dependency-graph.json`**
+
+```json
+{
+  "generated": "YYYY-MM-DD HH:MM",
+  "criticalPath": ["FEAT-001", "FEAT-005", "FEAT-012"],
+  "criticalPathLength": 3,
+  "batches": [
+    {
+      "batch": 1,
+      "features": ["FEAT-001", "FEAT-002", "FEAT-003"],
+      "parallel": true,
+      "blockedBy": []
+    },
+    {
+      "batch": 2,
+      "features": ["FEAT-004", "FEAT-005"],
+      "parallel": true,
+      "blockedBy": [1]
+    }
+  ],
+  "isolatedFeatures": ["FEAT-010", "FEAT-011"],
+  "graph": {
+    "FEAT-001": { "in": [], "out": ["FEAT-004", "FEAT-005"] },
+    "FEAT-002": { "in": [], "out": ["FEAT-006"] }
+  }
+}
+```
+
+### 1.5 Dependency Analysis Rules
+
+1. **No Dependencies**: Can start immediately in Batch 1
+2. **Single Dependency**: Waits for that feature only
+3. **Multiple Dependencies**: Waits for ALL dependencies
+4. **Circular Detection**: FAIL if cycles found - must restructure
+
+#### Circular Dependency Detection
+
+Before proceeding, verify no cycles exist in the dependency graph:
+
+```bash
+# Using jq to detect cycles (simplified check)
+# This finds features that depend on features that depend back on them
+cat .feature-tracking/features.json | jq '
+  .features as $all |
+  [.features[] |
+    select(.dependencies[] as $dep |
+      $all[] | select(.id == $dep) | .dependencies[] == .id
+    )
+  ] | if length > 0 then
+    "CIRCULAR DEPENDENCY DETECTED: \(.[].id)"
+  else
+    "No cycles detected"
+  end
+'
+```
+
+**If cycles are detected:**
+1. Identify the circular chain (A → B → A)
+2. Break the cycle by splitting one feature into sub-features
+3. Or merge dependent features into a single feature
+4. Re-run dependency analysis
+
+---
+
+## Phase 2: Parallel Execution Planning
+
+### 2.1 Calculate Optimal Batches
+
+Use topological sort to determine execution order:
+
+```
+Batch 1: All features with no dependencies (run in parallel)
+Batch 2: Features depending only on Batch 1 (run in parallel after Batch 1)
+Batch 3: Features depending on Batch 1 or 2 (run in parallel after Batch 2)
+...continue until all features assigned
+```
+
+### 2.2 Agent Assignment Strategy
+
+**Create file: `.feature-tracking/agent-assignments.json`**
+
+```json
+{
+  "strategy": "round-robin|load-balanced|priority-based",
+  "maxAgents": 4,
+  "assignments": [
+    {
+      "agentId": "agent-1",
+      "features": ["FEAT-001", "FEAT-004"],
+      "branch": "feature/agent-1-batch",
+      "status": "idle|working|waiting"
+    }
+  ]
+}
+```
+
+### 2.3 Create Main Feature Branch
+
+Before launching agents, create the integration branch where all features will be merged:
+
+```bash
+# Create and switch to the main feature branch
+git checkout -b feature/$PROJECT_NAME-main
+
+# Push to establish remote tracking
+git push -u origin feature/$PROJECT_NAME-main
+
+# Record in coordination files
+echo "feature/$PROJECT_NAME-main" > .feature-tracking/main-branch.txt
+```
+
+**Important:** All agent branches will merge INTO this branch, not directly to main/master.
+
+### 2.4 Create Master Coordination Document
+
+**Create file: `.feature-tracking/COORDINATION.md`**
+
+```markdown
+# Parallel Feature Build Coordination
+
+## Project: $ARGUMENTS
+## Mode: Parallel Execution
+## Max Agents: 4
+
+---
+
+## Execution Batches
+
+### Batch 1 (No Dependencies) - PARALLEL
+| Feature | Agent | Branch | Status |
+|---------|-------|--------|--------|
+| FEAT-001 | agent-1 | feat/agent-1-b1 | pending |
+| FEAT-002 | agent-2 | feat/agent-2-b1 | pending |
+| FEAT-003 | agent-3 | feat/agent-3-b1 | pending |
+
+### Batch 2 (Depends on Batch 1) - PARALLEL after Batch 1
+| Feature | Agent | Branch | Status |
+|---------|-------|--------|--------|
+
+---
+
+## Merge Queue
+
+| Order | Feature | From Branch | Status |
+|-------|---------|-------------|--------|
+
+---
+
+## Active Agents
+
+| Agent ID | Current Feature | Branch | Started |
+|----------|-----------------|--------|---------|
+```
+
+---
+
+## Phase 3: Agent Orchestration
+
+### 3.1 Launch Parallel Agents
+
+For each feature in the current batch, use the Task tool to spawn an agent:
+
+```markdown
+**Agent Instructions for FEAT-XXX:**
+
+You are implementing feature FEAT-XXX for project: $ARGUMENTS
+
+**Your Feature:**
+- ID: FEAT-XXX
+- Description: [description]
+- Verification Steps:
+  1. [step 1]
+  2. [step 2]
+  3. [step 3]
+
+**Your Branch:** feat/agent-X-FEAT-XXX
+
+**CRITICAL RULES:**
+1. Work ONLY on your assigned feature
+2. Create atomic, focused commits
+3. Do NOT modify features.json directly
+4. Write progress to: .feature-tracking/agents/agent-X-progress.md
+5. When complete, update: .feature-tracking/agents/agent-X-status.json
+
+**Workflow:**
+1. Create and checkout your branch: `git checkout -b feat/agent-X-FEAT-XXX`
+2. Implement the feature
+3. Test all verification steps
+4. Commit with message: `feat(FEAT-XXX): [description]`
+5. Update your status file to "completed"
+6. Push branch: `git push origin feat/agent-X-FEAT-XXX`
+
+**Status File Format (.feature-tracking/agents/agent-X-status.json):**
+```json
+{
+  "agentId": "agent-X",
+  "featureId": "FEAT-XXX",
+  "status": "completed",
+  "branch": "feat/agent-X-FEAT-XXX",
+  "commitHash": "[hash]",
+  "completedAt": "YYYY-MM-DD HH:MM",
+  "notes": "Any implementation notes"
+}
+```
+
+Report back when complete.
+```
+
+### 3.2 Agent Progress Files
+
+Each agent writes to: `.feature-tracking/agents/agent-X-progress.md`
+
+```markdown
+# Agent X Progress
+
+## Assigned Feature: FEAT-XXX
+## Branch: feat/agent-X-FEAT-XXX
+
+### Implementation Log
+
+**[HH:MM]** Started implementation
+- Created component structure
+- Added basic functionality
+
+**[HH:MM]** Testing verification steps
+- Step 1: PASS
+- Step 2: PASS
+- Step 3: PASS
+
+**[HH:MM]** Implementation complete
+- Committed: [hash]
+- Ready for merge
+```
+
+### 3.3 Monitor Agent Completion
+
+Poll agent status files until all agents in batch complete:
+
+```bash
+# Check all agent statuses with polling interval
+check_agents_complete() {
+  local all_complete=true
+  for f in .feature-tracking/agents/agent-*-status.json; do
+    if [ -f "$f" ]; then
+      status=$(cat "$f" | jq -r '.status')
+      if [ "$status" != "completed" ]; then
+        all_complete=false
+        echo "Agent $(basename $f): $status"
+      fi
+    else
+      all_complete=false
+    fi
+  done
+  $all_complete
+}
+
+# Poll with 30-second intervals until all agents complete
+while ! check_agents_complete; do
+  echo "Waiting for agents to complete..."
+  sleep 30
+done
+echo "All agents complete!"
+```
+
+**Alternative: File watching** (if available)
+```bash
+# Use inotifywait for real-time monitoring (Linux)
+inotifywait -m -e modify .feature-tracking/agents/*.json
+```
+
+---
+
+## Phase 4: Merge Coordination
+
+### 4.1 Merge Order Protocol
+
+After all agents in a batch complete:
+
+1. **Sort by Feature ID** for deterministic merge order
+2. **Merge sequentially** to main feature branch
+3. **Verify after each merge** that codebase still works
+
+### 4.2 Merge Workflow
+
+```bash
+# Read the main feature branch name (created in Phase 2.3)
+MAIN_BRANCH=$(cat .feature-tracking/main-branch.txt)
+
+# For each completed feature branch
+git checkout "$MAIN_BRANCH"
+git merge --no-ff feat/agent-X-FEAT-XXX -m "merge(FEAT-XXX): [description]
+
+Implemented by: agent-X
+Verification: All steps passed
+Batch: X of Y"
+
+# Test that merge didn't break anything
+[run tests or verification]
+
+# If merge conflicts:
+# 1. Resolve conflicts
+# 2. Run full test suite
+# 3. Commit resolution
+```
+
+### 4.3 Update Master Tracking
+
+After successful merge, update `.feature-tracking/features.json` using file locking to prevent race conditions:
+
+```bash
+# Acquire lock before updating shared tracking file
+LOCKFILE=".feature-tracking/.features.lock"
+
+acquire_lock() {
+  while ! mkdir "$LOCKFILE" 2>/dev/null; do
+    echo "Waiting for lock..."
+    sleep 1
+  done
+}
+
+release_lock() {
+  rmdir "$LOCKFILE"
+}
+
+# Usage
+acquire_lock
+# Update features.json here
+release_lock
+```
+
+**Update the feature entry:**
+```json
+{
+  "id": "FEAT-XXX",
+  "status": "passed",
+  "assignedAgent": "agent-X",
+  "branch": "feat/agent-X-FEAT-XXX",
+  "implementedAt": "YYYY-MM-DD HH:MM",
+  "mergedAt": "YYYY-MM-DD HH:MM",
+  "commitHash": "[merge-commit-hash]"
+}
+```
+
+### 4.4 Conflict Resolution Protocol
+
+If merge conflicts occur:
+
+1. **Identify conflicting files**
+2. **Analyze which agent's changes take precedence**
+3. **Resolve favoring the more complete implementation**
+4. **Document resolution** in merge commit message
+5. **Re-verify affected features**
+
+---
+
+## Phase 5: Batch Progression
+
+### 5.1 Batch Completion Check
+
+```bash
+# Verify all features in batch are merged
+cat .feature-tracking/features.json | jq '[.features[] | select(.batch == 1 and .status != "passed")] | length'
+# Must return 0
+```
+
+### 5.2 Advance to Next Batch
+
+1. Update COORDINATION.md with batch completion status
+2. Identify next batch of features
+3. Assign to agents (may reuse same agents)
+4. Launch new parallel execution round
+
+### 5.3 Continue Until All Batches Complete
+
+```
+While batches remain:
+  1. Launch agents for current batch (parallel)
+  2. Wait for all agents to complete
+  3. Merge all branches sequentially
+  4. Verify merged codebase
+  5. Advance to next batch
+```
+
+---
+
+## Phase 6: Recovery & Error Handling
+
+### 6.1 Agent Failure Protocol
+
+If an agent fails to complete:
+
+1. **Check agent progress file** for last known state
+2. **Salvage work if possible**: `git cherry-pick` good commits
+3. **Reassign feature** to different agent or handle sequentially
+4. **Do NOT block other agents** in same batch
+
+### 6.2 Merge Failure Protocol
+
+If merge cannot be resolved:
+
+1. **Abort merge**: `git merge --abort`
+2. **Identify conflicting features**
+3. **Re-implement one feature** to avoid conflict
+4. **Or execute features sequentially** instead of parallel
+
+### 6.3 Rollback Batch
+
+If entire batch must be reverted:
+
+```bash
+# Find commit before batch started
+git log --oneline | grep "Batch X start"
+
+# Revert all batch commits
+git revert [batch-commits]
+
+# Retry batch with adjusted approach
+```
+
+---
+
+## Phase 7: Completion & Reporting
+
+### 7.1 Final Verification
+
+```bash
+# All features must be passed
+cat .feature-tracking/features.json | jq '[.features[] | select(.status != "passed")] | length'
+# Must return 0
+```
+
+### 7.2 Generate Performance Report
+
+**Create file: `.feature-tracking/PERFORMANCE-REPORT.md`**
+
+```markdown
+# Parallel Execution Performance Report
+
+## Summary
+- **Total Features**: X
+- **Total Batches**: Y
+- **Max Parallelism**: 4 agents
+- **Total Duration**: Z hours
+
+## Batch Breakdown
+
+| Batch | Features | Duration | Parallelism |
+|-------|----------|----------|-------------|
+| 1 | 4 | 30min | 4x |
+| 2 | 3 | 25min | 3x |
+| 3 | 2 | 20min | 2x |
+
+## Efficiency Metrics
+
+- **Sequential Estimate**: X hours
+- **Parallel Actual**: Y hours
+- **Speedup Factor**: X/Y
+- **Agent Utilization**: Z%
+
+## Merge Statistics
+
+- **Clean Merges**: X
+- **Conflicts Resolved**: Y
+- **Re-implementations**: Z
+```
+
+### 7.3 Final Commit
+
+```bash
+git add .
+git commit -m "feat: complete parallel build of $ARGUMENTS
+
+Execution Summary:
+- Total features: X
+- Batches: Y
+- Max parallel agents: 4
+- Speedup: Zx over sequential
+
+All features verified and merged successfully.
+See .feature-tracking/PERFORMANCE-REPORT.md for details"
+```
+
+---
+
+## Usage Examples
+
+### Start Parallel Feature Build
+
+```
+/dev:parallel-feature-build e-commerce checkout system
+```
+
+### With Agent Limit
+
+```
+/dev:parallel-feature-build --agents 2 user dashboard
+```
+
+### Monitor Progress
+
+```bash
+# View coordination status
+cat .feature-tracking/COORDINATION.md
+
+# Check agent statuses
+ls .feature-tracking/agents/
+
+# View dependency graph
+cat .feature-tracking/dependency-graph.json | jq '.batches'
+```
+
+---
+
+## Comparison: Sequential vs Parallel
+
+| Aspect | Sequential | Parallel |
+|--------|------------|----------|
+| Speed | Slower | Faster (up to Nx) |
+| Complexity | Simple | Complex coordination |
+| Merge Risk | None | Potential conflicts |
+| Best For | Small projects | Large feature sets |
+| Agent Count | 1 | 2-4+ |
+
+---
+
+## Key Principles
+
+1. **Independence First**: Only parallelize truly independent features
+2. **Conservative Batching**: When in doubt, add to later batch
+3. **Merge Early, Merge Often**: Don't let branches diverge too long
+4. **Agent Isolation**: Each agent owns their branch exclusively
+5. **Deterministic Merge Order**: Same order every time for reproducibility
+6. **Fail Safe**: Any failure falls back to sequential execution

+# Parallel Feature Build Command - Implementation Checklist
+
+## Overview
+Creating a variation of the incremental feature build command that leverages agents for parallel implementation of independent features.
+
+## Tasks
+
+- [x] Create this checklist
+- [x] Create the command file at `.claude/commands/dev/parallel-feature-build.md`
+- [x] Include dependency graph generation
+- [x] Include parallel batch identification
+- [x] Include agent orchestration workflow
+- [x] Include merge/conflict resolution protocols
+- [x] Include synchronized progress tracking
+- [x] Commit changes
+
+## Key Differences from Sequential Version
+
+1. **Dependency Graph Analysis**
+   - Build directed acyclic graph (DAG) of feature dependencies
+   - Identify independent feature batches
+   - Calculate critical path
+
+2. **Parallel Execution**
+   - Launch multiple agents for independent features
+   - Each agent works on isolated branch
+   - Coordinate via shared tracking files
+
+3. **Merge Strategy**
+   - Sequential merge of completed features
+   - Conflict detection and resolution
+   - Verification after each merge
+
+4. **Synchronized Tracking**
+   - Lock-based updates to features.json
+   - Agent-specific progress files
+   - Master coordination document
