## Merge Conflict Resolution Guidance

### Critical Areas for Conflicts

Based on the analysis of these 9 commits, the following areas are most likely to have conflicts with your local changes:

#### 1. **Tool Module Structure (HIGH PRIORITY)**
- **Conflict Zone**: `src/microsoft_mcp/tools.py` vs modular `src/microsoft_mcp/tools/*.py`
- **Issue**: Commit #1 (d65f1f6) split the monolithic tools file into separate modules
- **Resolution Strategy**:
  - Accept origin's modular structure (delete local `tools.py` if it exists)
  - Port any local changes to the appropriate category module
  - Use the new import structure from `tools/__init__.py`

#### 2. **Validation Framework (HIGH PRIORITY)**
- **Conflict Zone**: `src/microsoft_mcp/validators.py`
- **Issue**: Commits #3-5 added 20+ validation functions and enhanced existing ones
- **Resolution Strategy**:
  - Accept origin's enhanced validators
  - Verify your local tools use the new `require_confirm` pattern
  - Check for new validators like `validate_choices` and `validate_json_payload`

#### 3. **Tool Naming Convention (BREAKING CHANGE)**
- **Conflict Zone**: All tool functions
- **Issue**: Commit #3 renamed all 50 tools to `category_verb_entity` convention
- **Resolution Strategy**:
  - Update all tool names to follow new convention (e.g., `list_emails` → `email_list`)
  - Update any client code or tests referencing old tool names
  - Verify tool annotations include safety levels

#### 4. **Server Configuration (MEDIUM PRIORITY)**
- **Conflict Zone**: `src/microsoft_mcp/server.py`
- **Issue**: Commits #7-9 added health checks, logging config, and env file support
- **Resolution Strategy**:
  - Accept origin's enhanced server with health checks
  - Verify `--env-file` argument support is present
  - Check for new modules: `health_check.py` and `logging_config.py`

#### 5. **Testing Infrastructure (MEDIUM PRIORITY)**
- **Conflict Zone**: `tests/` directory
- **Issue**: Commits #4-6 added 10+ new test files
- **Resolution Strategy**:
  - Accept all new test files from origin
  - Update `tests/conftest.py` with new fixtures
  - Ensure integration tests include `confirm=True` parameters

#### 6. **Documentation Files (LOW PRIORITY)**
- **Conflict Zone**: `CHANGELOG.md`, `FILETREE.md`, `.gitignore`
- **Issue**: Multiple commits updated these files
- **Resolution Strategy**:
  - Accept origin's versions (they're more comprehensive)
  - Append any unique local changes to CHANGELOG.md
  - Use mandatory update rules from CLAUDE.md

### Recommended Merge Strategy

**Option 1: Rebase Your Local Changes (RECOMMENDED)**
```bash
# Backup your current work
git branch backup-local-master

# Rebase your 2 local commits onto origin/master
git rebase origin/master

# Resolve conflicts as they arise, using guidance above
# Test thoroughly after each conflict resolution
uv run pytest tests/ -v
```

**Option 2: Merge with Manual Conflict Resolution**
```bash
# Backup your current work
git branch backup-local-master

# Merge origin/master into your branch
git merge origin/master

# Resolve all conflicts manually
# Prioritize origin's changes for structural/framework code
# Preserve your local business logic changes
```

### Conflict Resolution Priority Order

1. **Accept Origin**: Tool modularization structure
2. **Accept Origin**: Validation framework enhancements
3. **Review Carefully**: Tool function implementations (merge your logic with origin's validation)
4. **Accept Origin**: Server infrastructure (health checks, logging)
5. **Accept Origin**: Test infrastructure
6. **Accept Origin**: Documentation (CHANGELOG.md, FILETREE.md)
7. **Preserve Local**: Business-specific logic or features unique to your branch

### Post-Merge Validation Checklist

After resolving conflicts:

- [ ] Run type checking: `uv run pyright`
- [ ] Run all tests: `uv run pytest tests/ -v`
- [ ] Verify all tools follow `category_verb_entity` naming
- [ ] Confirm `confirm=True` parameter present on destructive operations
- [ ] Test authentication flow: `uv run authenticate.py`
- [ ] Test server startup: `uv run microsoft-mcp`
- [ ] Update CHANGELOG.md with merge resolution notes (MANDATORY per CLAUDE.md)
- [ ] Update FILETREE.md if new files were added (MANDATORY per CLAUDE.md)

### Key Dependencies to Check

After merge, verify these dependencies are properly installed:
```bash
# Check pyproject.toml has:
- httpx (for secure file downloads)
- pytest-asyncio (for async tests)
- All new test dependencies

# Update dependencies
uv sync
```
