Subject: [PATCH 1/6] feat(workflow): implement Phase 6 built-in actions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Comprehensive implementation of built-in workflow actions:

## New Action Implementations
- **Shell Actions** ()
  - Enhanced execution with variable substitution
  - Dangerous command detection (rm -rf, dd if=, etc.)
  - Proper error handling with result storage

- **AI Prompt Actions** ()
  - AI model integration with proper agent context
  - Variable expansion in prompts
  - Model switching support within prompts

- **Git Actions** ()
  - , , ,  implementations
  - GitHub CLI integration with proper error handling
  - Message variable substitution

- **PR Actions** ()
  - , ,  actions
  - GitHub CLI integration via gh command
  - Title/body/base parameter expansion

## Integration
- Updated  with proper imports/registration
- Full TypeScript type safety with proper casting
- Variable substitution support for all actions: {{variable}} patterns

## Demo Workflows
-  - Git automation workflow
-  - AI-assisted workflows
-  - Comprehensive multi-action demo

## Testing
- All 27 existing workflow tests passing ✅
- TypeScript compilation successful ✅
- Build verification complete ✅

This completes Phase 6 of the workflow system, providing production-ready
built-in actions for common automation scenarios.

+# Interactive Workflow Testing Guide
+
+This guide shows how to test the new Phase 4 (Loop) and Phase 5 (Interactive) workflow features.
+
+## Quick Start
+
+```bash
+cd /Users/layne/Development/genai/dev3
+pnpm dev
+```
+
+Once Codi starts, try these commands:
+
+---
+
+## Test 1: List Available Workflows
+
+```
+/workflow list
+```
+
+Should show:
+- test-conditional
+- test-interactive
+- test-interactive-comprehensive
+- test-interactive-enhanced
+- test-loop
+- test-model-switch
+- test-switch-demo
+
+---
+
+## Test 2: Show Workflow Details
+
+### Simple Interactive Workflow
+```
+/workflow show test-interactive
+```
+
+Should display:
+- Description
+- Step count
+- Individual step details
+
+### Enhanced Interactive Workflow
+```
+/workflow show test-interactive-enhanced
+```
+
+Should show advanced features like:
+- Multiple input types (confirm, choice, text)
+- Timeout configurations
+- Validation patterns
+- Default values
+
+### Loop Workflow
+```
+/workflow show test-loop
+```
+
+Should show:
+- Loop step with iteration logic
+- Condition for loop execution
+- maxIterations safety limit
+
+---
+
+## Test 3: Validate Workflow Syntax
+
+```
+/workflow validate test-interactive
+```
+
+Should report: ✅ Workflow is valid
+
+```
+/workflow validate test-interactive-enhanced
+```
+
+Should report: ✅ Workflow is valid (with enhanced features)
+
+```
+/workflow validate test-loop
+```
+
+Should report: ✅ Workflow is valid
+
+---
+
+## Test 4: Run Simple Workflow
+
+```
+/workflow-run test-interactive
+```
+
+Expected behavior:
+1. Step 1 (shell): Welcome message
+2. Step 2 (interactive): Prompt for confirmation
+3. Step 3 (shell): Completion message
+
+---
+
+## Test 5: Run Enhanced Workflow
+
+```
+/workflow-run test-interactive-enhanced
+```
+
+Expected behavior:
+1. Welcome message
+2. Interactive confirmation with timeout
+3. User preferences with choice input
+4. Multiple interactive interactions
+5. Completion message
+
+---
+
+## Test 6: Run Loop Workflow
+
+```
+/workflow-run test-loop
+```
+
+Expected behavior:
+1. Initialize loop variables
+2. Execute loop body with iteration tracking
+3. Check condition for repeat
+4. Respect maxIterations limit
+5. Complete when condition fails
+
+---
+
+## Test 7: Comprehensive Test
+
+```
+/workflow-run test-interactive-comprehensive
+```
+
+This workflow has:
+- 7 total steps
+- 3 interactive steps
+- Shell commands between interactions
+ Demonstrates a real-world workflow pattern
+
+---
+
+## Expected Features
+
+### Phase 4 - Loop Support ✓
+- Execute steps in iteration
+- Loop condition checking
+- maxIterations safety limit
+- Iteration counting in state
+
+### Phase 5 - Interactive Features ✓
+- Multiple input types:
+  - `text` - plain text input
+  - `password` - masked input
+  - `confirm` - yes/no confirmation
+  - `choice` - select from options
+  - `multiline` - multi-line text
+- Timeout handling (`timeoutMs`)
+- Default values (`defaultValue`)
+- Validation patterns (`validationPattern`)
+- Choice options (`choices` array)
+
+---
+
+## Troubleshooting
+
+If workflows don't work:
+
+1. Check workflow files exist:
+   ```bash
+   ls -la workflows/
+   ```
+
+2. Verify build:
+   ```bash
+   pnpm build
+   ```
+
+3. Run tests:
+   ```bash
+   pnpm test workflow
+   ```
+
+4. Check integration:
+   ```bash
+   grep "interactive" src/workflow/steps/index.ts
+   grep "loop" src/workflow/steps/index.ts
+   ```
+
+---
+
+## Verification Summary
+
+From automated checks:
+
+| Workflow | Steps | Interactive | Loop | Status |
+|----------|-------|-------------|------|--------|
+| test-interactive | 3 | 1 | 0 | ✅ |
+| test-interactive-enhanced | 8 | 5 | 0 | ✅ |
+| test-interactive-comprehensive | 7 | 3 | 0 | ✅ |
+| test-loop | 4 | 0 | 1 | ✅ |
+
+All workflows validated and ready for testing! 🚀

Subject: [PATCH 3/6] test(workflow): fix mock issues and enhance test coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed mock implementation issues and improved test coverage:

## Bug Fixes
- Fixed mock issues in test file
- Proper mocking of fs and child_process modules
- Replaced problematic vi.mocked() calls with direct mocks

## Test Enhancements
- Increased from 16 to 20 comprehensive tests
- Added security validation tests (branch names, PR titles)
- Added tests for variable substitution syntax
- Added edge case testing for control characters

## Security Tests
- Tests for command injection prevention in branch names
- Tests for PR title length validation (max 256 chars)
- Tests for control character rejection
- Tests for special character validation

All 47 workflow tests passing ✅

Subject: [PATCH 4/6] test(workflow): add comprehensive edge case tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added 13 comprehensive edge case tests covering:

## Security Validation
- Branch name injection prevention (command injection patterns)
- PR title validation (whitespace, control characters, max length)
- Command injection detection (rm -rf, pipe commands)

## Variable Substitution Edge Cases
- Undefined/null/empty variable handling
- Multiple variable expansion scenarios
- Special character handling

## Test Coverage
- 13 focused edge case tests
- All 60 workflow tests passing ✅
- Build verification successful ✅

This completes the security testing suite for Phase 6.

Subject: [PATCH 5/6] feat(workflow): initial Phase 7 AI-assisted workflow
 builder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Phase 7 Implementation - AI-Assisted Building

This implements the core foundation for Phase 7 with:

### ✅ New Command: /workflow-build
- Command registration with /wbuild alias
- Template-based workflow generation
- Basic natural language workflow creation
- Usage: /workflow-build "description" or /workflow-build template (name)

### ✅ Template System
- Pre-built workflow templates:
  - deployment: Git deployment workflow with testing
  - documentation: Documentation generation workflow
  - refactor: Code refactoring workflow
- Template listing command: /workflow-build template list

### ✅ File Generation
- Automatic YAML workflow file creation
- Standard workflows directory setup
- Proper workflow naming conventions

### 🔲 Next Steps Needed
- Real AI integration for natural language parsing
- Interactive step-by-step builder UI
- Advanced validation suggestions

### 🧪 Testing
- Unit tests covering command functionality
- Build verification successful
- All existing workflow tests still passing

Phase 7 foundations complete - ready for AI integration!

+- [x] Create interactive workflow builder command ✅ IMPLEMENTED `/workflow-build`
+- [ ] Implement step-by-step workflow creation with AI guidance ⏳ NEEDED
+- [x] Add workflow templates library ✅ IMPLEMENTED Built-in templates
+- [ ] Create natural language workflow import (describe workflow, AI generates YAML) ✅ PARTIAL IMPLEMENTED
+- [ ] Add workflow validation and suggestions 🔲 NEEDED
+- [ ] Design AI prompt templates for common workflows 🔲 NEEDED
 
 **Rationale**: Extended from 1 week to 2 weeks due to complexity of natural language understanding and AI prompt engineering required for this phase.
