+
+### Strict Code Review Criteria Applied
+Based on the git package conversion, establish these mandatory criteria for all future conversions:
+
+#### 1. **Code Quality Standards**
+- ✅ **No low-quality or rushed code**: All logic must be clear, maintainable, and follow conventions
+- ✅ **Professional implementations**: Real functionality, not placeholder code
+- ✅ **Proper error handling**: Comprehensive error types with meaningful messages
+- ✅ **Security considerations**: Credential handling, URL masking, secure configurations
+
+#### 2. **No Nonsense Policy**
+- ✅ **No unused variables or imports**: Clean, purposeful code only
+- ✅ **No redundant functions**: Every function serves a clear purpose
+- ✅ **No unnecessary changes**: All modifications must add value
+
+#### 3. **Regression Prevention**
+- ✅ **All existing functionality preserved**: No breaking changes
+- ✅ **Comprehensive testing**: Both unit tests and integration tests
+- ✅ **Backward compatibility**: Smooth transition for existing users
+
+#### 4. **Zero Placeholder Code**
+- ✅ **No TODO/FIXME comments**: All code must be production-ready
+- ✅ **No stub implementations**: Real functionality only
+- ✅ **No `assert!(true)` tests**: All tests must validate actual behavior
+
+#### 5. **Test Integrity Requirements**
+- ✅ **Real behavior validation**: Tests must verify actual functionality
+- ✅ **Meaningful assertions**: No trivial passing tests
+- ✅ **Environment resilience**: Graceful handling of network/system constraints
+- ✅ **Comprehensive coverage**: Unit, integration, and rhai script tests

+   - Replaced hardcoded configurations with environment variables
+
+3. **Improved Test Quality**:
+   - Replaced fake tests with real behavior validation
+   - Added comprehensive error handling tests
+   - Implemented environment-resilient test scenarios
+   - Fixed API usage bugs (Vec<GitRepo> vs single GitRepo)
+
+4. **Production Features**:
+   - Added structured logging with appropriate levels
+   - Implemented configurable Redis connections with fallbacks
+   - Enhanced error messages with meaningful context
+   - Added comprehensive documentation with security considerations
+
+5. **Code Quality Enhancements**:

@@ -81,6 +81,36 @@ The `herodo` CLI tool likely leverages `GitExecutor` to provide its scriptable G
 
 Both `git.rs` and `git_executor.rs` define their own specific error enums (`GitError` and `GitExecutorError` respectively) to provide detailed information about issues encountered during Git operations. These errors cover a wide range of scenarios from command execution failures to authentication problems and invalid configurations.
 
+## Configuration
+
+The git module supports configuration through environment variables:
+
+### Environment Variables
+
+- **`REDIS_URL`**: Redis connection URL (default: `redis://127.0.0.1/`)
+- **`SAL_REDIS_URL`**: Alternative Redis URL (fallback if REDIS_URL not set)
+- **`GIT_DEFAULT_BASE_PATH`**: Default base path for git operations (default: system temp directory)
+
+### Example Configuration
+
+```bash
+# Set Redis connection
+export REDIS_URL="redis://localhost:6379/0"
+
+# Set default git base path
+export GIT_DEFAULT_BASE_PATH="/tmp/git_repos"
+
+# Run your application
+herodo your_script.rhai
+```
+
+### Security Considerations
+
+- Passwords are never embedded in URLs or logged
+- Temporary credential helpers are used for HTTPS authentication
+- Redis URLs with passwords are masked in logs
+- All temporary files are cleaned up after use
+
 ## Summary
 
 The `git` module offers a powerful and flexible interface to Git, catering to both simple, high-level repository interactions and complex, authenticated command execution scenarios. Its integration with Redis for authentication configuration makes it particularly well-suited for automated systems and tools like `herodo`.
