# Task 1: API Verification and Foundation (Minutes 0-15)
## Objective
Verify the actual availability of Commitizen's git APIs and establish the foundation for git integration based on what's actually available.
## Implementation Steps
### Step 1: Create API Verification Script
**File**: `tests/verify_commitizen_git_apis.py`
```python
def test_commitizen_imports() -> Dict[str, Any]:
"""
Test which Commitizen APIs are actually available.
Returns:
Dict with categories: basic_apis, git_apis, command_apis, exception_apis
Each category maps API names to boolean availability
"""
# Test basic APIs (known to work): factory, BaseConfig, CommitizenException
# Test git APIs (questionable): GitCommit, is_git_project, get_staged_files_remotes
# Test command APIs: Commit class
# Test git exceptions: GitCommandError, NoStagedFilesError, NotAGitProjectError
def determine_implementation_strategy(results: Dict[str, Any]) -> str:
"""
Determine implementation strategy based on API availability.
Returns:
"commitizen_native" | "commitizen_git_only" | "subprocess_fallback"
"""
# If git APIs + command APIs available -> commitizen_native
# If only git APIs available -> commitizen_git_only
# If no git APIs available -> subprocess_fallback
```
### Step 2: Design Implementation Strategies
#### Strategy A: Commitizen Native APIs
```python
class GitService:
"""Use Commitizen's internal git APIs directly."""
def __init__(self, repo_path: Optional[str] = None):
# Initialize with commitizen.git.GitCommit
# Use commitizen.git.is_git_project for validation
def get_staged_files(self) -> List[str]:
# Use commitizen.git.get_staged_files_remotes()
def execute_commit(self, message: str, **kwargs) -> Dict[str, Any]:
# Use GitCommit.commit() method
```
#### Strategy B: Subprocess Fallback
```python
class GitService:
"""Use subprocess calls to git commands."""
def __init__(self, repo_path: Optional[str] = None):
# Validate git repo with: subprocess.run(["git", "rev-parse", "--git-dir"])
def get_staged_files(self) -> List[str]:
# Use: subprocess.run(["git", "diff", "--cached", "--name-only"])
def execute_commit(self, message: str, **kwargs) -> Dict[str, Any]:
# Use: subprocess.run(["git", "commit", "-m", message])
```
## Success Criteria
- [x] Verification script determines API availability ✅ **COMPLETED**
- [x] Implementation strategy chosen based on results ✅ **COMPLETED** (`commitizen_native`)
- [x] Foundation class structure defined ✅ **COMPLETED**
## Implementation Results
### ✅ API Verification Script Created
**File**: `tests/verify_commitizen_git_apis.py`
- Comprehensive testing of Commitizen git APIs
- Determined `commitizen_native` strategy is optimal
- Verified availability of: `is_git_project`, `is_staging_clean`, `commit`, `add`, `get_commits`
### ✅ GitService Foundation Implemented
**File**: `src/commitizen_mcp_connector/git_service.py`
- Repository validation using `is_git_project()`
- Safety-first approach with force flags
- Preview and execution modes
- Comprehensive error handling
### 🔍 Critical Security Finding
**Status**: ⚠️ **SECURITY REVIEW REQUIRED**
During implementation, a critical security analysis revealed that allowing MCP to execute git commands poses significant risks:
1. **Arbitrary Code Execution Risk** (HIGH)
2. **Privilege Escalation** (HIGH)
3. **Unintended Repository Modification** (MEDIUM)
**See**: `journal/git/security-analysis.md` for complete security assessment.
**Recommendation**: Current implementation should only be used in development environments with trusted users until security enhancements are implemented.
## Next Steps
1. **PRIORITY**: Address security concerns before proceeding
2. Implement security enhancements from security analysis
3. Proceed to Task 2 with enhanced security controls
