# Phase 2: Conflict Prevention - Detailed Plan

**Status**: Planning
**Timeline**: Week 12-15 (4 weeks)
**Version Target**: v0.9.0
**Created**: 2025-10-19

---

## Overview

Phase 2 focuses on **conflict prevention** through intelligent file change analysis, dependency detection, and proactive warnings. This transforms Clauxton from a reactive tool (post-hoc detection) to a **proactive assistant** (pre-merge prevention).

---

## Current Status (Post-Week 11)

### ✅ Completed (Phase 0, 1, 1+)

**Core Features**:
- ✅ Knowledge Base (CRUD, TF-IDF search, 94% coverage)
- ✅ Task Management (Dependencies, DAG validation, AI recommendations)
- ✅ MCP Server (12 tools: 6 KB + 6 Task)
- ✅ CLI (Full CRUD for KB and Tasks)
- ✅ YAML Persistence (Atomic writes, backups, 700/600 permissions)

**Quality & Infrastructure**:
- ✅ CI/CD (GitHub Actions, 44s runtime, 100% pass rate)
- ✅ Test Coverage (94%, 267 tests, all passing)
- ✅ Documentation (23 files, 520 KB, A+ quality)
- ✅ Community Infrastructure (Issue/PR templates, CONTRIBUTING.md)

**Production Ready**:
- ✅ v0.8.0 released to PyPI
- ✅ Production Ready status
- ✅ Professional project image

### ❌ Not Yet Implemented (Phase 2 Scope)

**Conflict Prevention**:
- ❌ File conflict detection (pre-merge analysis)
- ❌ Drift detection (expected vs actual state)
- ❌ Risk scoring (low/medium/high)
- ❌ Safe execution order recommendations

**Advanced Features**:
- ❌ Lifecycle hooks (pre-commit, post-edit)
- ❌ Event logging (audit trail)
- ❌ Conflict Detector Subagent

## Week 12: Conflict Detection Core

### Goals
- Implement file-based conflict detection
- Add risk scoring algorithm
- Create conflict detection MCP tools

### Day 1-2: Conflict Detector Core

**File**: `clauxton/core/conflict_detector.py`

**Implementation**:
```python
class ConflictDetector:
    """Detect potential conflicts between tasks."""

    def __init__(self, task_manager: TaskManager):
        self.task_manager = task_manager

    def detect_conflicts(
        self,
        task_id: str
    ) -> List[ConflictReport]:
        """Detect conflicts for a specific task."""
        task = self.task_manager.get_task(task_id)
        conflicts = []

        # Get all in_progress tasks
        active_tasks = self.task_manager.list_tasks(status="in_progress")

        for other_task in active_tasks:
            if other_task.id == task_id:
                continue

            # Check file overlap
            overlap = set(task.files_to_edit) & set(other_task.files_to_edit)
            if overlap:
                conflicts.append(self._create_file_overlap_conflict(
                    task, other_task, overlap
                ))

            # Check dependency violations
            if self._violates_dependency(task, other_task):
                conflicts.append(self._create_dependency_conflict(
                    task, other_task
                ))

        return conflicts

    def calculate_risk_score(
        self,
        conflict: ConflictReport
    ) -> float:
        """Calculate risk score (0.0-1.0)."""
        if conflict.conflict_type == "file_overlap":
            # High risk if many files overlap
            return min(1.0, len(conflict.details.split(",")) * 0.2)
        elif conflict.conflict_type == "dependency_violation":
            # Very high risk
            return 0.9
        elif conflict.conflict_type == "scope_drift":
            # Medium risk
            return 0.5
        return 0.0

    def recommend_safe_order(
        self,
        tasks: List[Task]
    ) -> List[str]:
        """Recommend safe execution order."""
        # Topological sort based on dependencies
        # Returns list of task IDs in safe order
        pass
```

**Tests** (`tests/core/test_conflict_detector.py`):

```python
@mcp.tool()
def detect_conflicts(task_id: str) -> list[dict]:
    """Detect potential conflicts for a task.

    Args:
        task_id: Task ID to check (e.g., "TASK-001")

    Returns:
        List of conflict reports with risk scores
    """
    detector = ConflictDetector(task_manager)
    conflicts = detector.detect_conflicts(task_id)
    return [conflict.dict() for conflict in conflicts]

@mcp.tool()

    Returns:
        Task IDs in recommended execution order
    """
    detector = ConflictDetector(task_manager)
    tasks = [task_manager.get_task(tid) for tid in task_ids]
    return detector.recommend_safe_order(tasks)
```

**Tests** (`tests/mcp/test_conflict_tools.py`):

        return

    click.secho(f"⚠️ Found {len(conflicts)} conflict(s):", fg="yellow")
    for conflict in conflicts:
        risk_level = "🔴 HIGH" if conflict.risk_score > 0.7 else "🟡 MEDIUM"

- `test_conflict_tools.py`: 20+ tests
- `test_conflicts_cli.py`: 15+ tests
- `test_hooks_cli.py`: 15+ tests
- Performance tests: 10+ tests
- Edge case tests: 40+ tests

### Integration Tests (30+ new tests)
- End-to-end conflict detection workflow
- End-to-end drift detection workflow
- Git hooks integration
- MCP server integration
- Event logging integration

### Manual Testing
- Real-world projects (3-5 projects)
- Multi-task scenarios
- Git operations (commit, merge)
- Performance testing (100+ tasks, 1000+ events)

**Total Tests**: 267 (current) → 500+ (target)

## Risk Management

### Technical Risks

| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| Git integration complexity | Medium | High | Use subprocess, extensive testing |
| False positives in conflict detection | High | Medium | Conservative thresholds, user feedback |
| Performance degradation | Medium | Medium | Caching, benchmarking, profiling |
| Hook installation issues | Low | Medium | Clear error messages, fallback to manual |

### Mitigation Strategies

1. **Git Integration**:
   - Use well-tested subprocess commands
   - Provide manual fallback (don't require Git)
   - Test on multiple Git versions

2. **False Positives**:
   - Start with conservative thresholds (risk > 0.7 = warning)
   - Collect user feedback
   - Iterate on algorithm

3. **Performance**:
   - Add caching for expensive operations
   - Profile with `cProfile`
   - Set performance benchmarks upfront

4. **Hook Installation**:
   - Clear error messages
   - Provide manual installation instructions
   - Don't make hooks mandatory
