# Week 12 Day 5 Complete: CLI Commands for Conflict Detection

**Date**: 2025-10-20
**Phase**: Phase 2 - Conflict Prevention
**Week**: 12 (Conflict Detection Core)
**Day**: 5 of 7

---

## ✅ Completed Tasks

### 1. CLI Command Implementation (clauxton/cli/conflicts.py)

Created comprehensive CLI module (+290 lines, 3 commands):

#### conflict detect
**Purpose**: Detect conflicts for a specific task

**Features**:
- Clean, colorized terminal output
- Risk level visualization (HIGH/MEDIUM/LOW in colors)
- File overlap count
- Verbose mode for detailed conflict information
- Clear recommendations

**Example Output**:
```
Conflict Detection Report
Task: TASK-002 - Add OAuth support
Files: 2 file(s)

⚠ 1 conflict(s) detected

Conflict 1:
  Task: TASK-001 - Refactor JWT authentication
  Risk: MEDIUM (67%)
  Files: 1 overlapping
  → Complete TASK-002 before starting TASK-001, or coordinate changes
```

#### conflict order
**Purpose**: Recommend safe execution order for tasks

**Features**:
- Topological sort with conflict analysis
- Numbered execution order
- Context-aware messages (dependencies vs. conflicts)
- Details mode showing priority, files, dependencies
- Visual priority indicators

**Example Output**:
```
Task Execution Order
Tasks: 3 task(s)

Order respects dependencies and minimizes conflicts

Recommended Order:
1. TASK-001 - Refactor authentication
2. TASK-002 - Add OAuth support
3. TASK-003 - Update user model

💡 Execute tasks in this order to minimize conflicts
```

#### conflict check
**Purpose**: Check file availability before editing

**Features**:
- Multi-file support
- Task-by-task breakdown
- File-by-file status (verbose mode)
- Clear availability indicators (✓/✗)
- Coordination recommendations

**Example Output**:
```
File Availability Check
Files: 2 file(s)

⚠ 2 task(s) editing these files

Conflicting Tasks:
  TASK-001 - Refactor authentication
  Status: in_progress
  Editing: 1 of your file(s)

  TASK-003 - Update user model
  Status: in_progress
  Editing: 1 of your file(s)

💡 Coordinate with task owners or wait until tasks complete
```

### 2. CLI Tests (tests/cli/test_conflict_commands.py)

Created comprehensive test suite (+360 lines, 13 tests):

#### Test Coverage:
- ✅ `test_conflict_detect_no_conflicts`: Basic detection with no conflicts

- ✅ `test_conflict_detect_verbose`: Verbose output mode
- ✅ `test_conflict_detect_task_not_found`: Error handling

### 3. Documentation Update (docs/conflict-detection.md)

Enhanced CLI Commands section (+247 lines):

#### Added Content:
1. **Command Syntax**: Complete syntax for all 3 commands
2. **Examples**: 13 example commands with expected output
3. **Options**: All flags and options documented
4. **Exit Codes**: Success/error codes for each command
5. **Common Workflows**: 3 real-world workflow examples
   - Pre-Start Workflow
