## Part 1: Git Auto-Initialization
### Problem Statement
**Before**: Both `write` and `git_feature` tools had different behaviors when git repository was missing:
- `write`: Inline git init logic (~80 lines) in `ensureProjectGitRepo()`
- `git_feature`: Threw ValidationError requiring manual `git init`
- **Result**: Inconsistent UX, code duplication, manual setup friction
**After**: Seamless auto-initialization with consistent behavior across all tools.
### Implementation Details
#### 1. Shared Utility (`src/utils/gitInit.ts` - 136 lines)
**Strategy**:
```typescript
export async function ensureGitInitialized(repoPath: string): Promise<GitInitResult> {
// 1. Check if .git directory exists → skip if present
// 2. Run git init to create repository
// 3. Detect global config: git config --global user.name/email
// 4. If global config exists → use automatically
// 5. If no global config → set defaults (user.name="MCP Gas", user.email="mcp@gas.local")
}
```
**Return Interface**:
```typescript
interface GitInitResult {
initialized: boolean; // true if git repo exists
isNew: boolean; // true if just created
configSource: 'global' | 'defaults' | 'existing';
repoPath: string;
}
```
**Smart Config Detection**:
- Checks for global git config with `git config --global user.name` and `user.email`
- Uses global config automatically when available
- Falls back to sensible defaults: `MCP Gas <mcp@gas.local>`
#### 2. GitFeatureTool Update (`src/tools/git/GitFeatureTool.ts`)
**Changed**:
```typescript
// OLD: Threw error if no .git
const gitPath = join(gitRoot, '.git');
try {
await access(gitPath, constants.F_OK);
} catch {
throw new ValidationError('git', gitRoot, 'No git repository found...');
}
// NEW: Auto-initializes
const gitResult = await ensureGitInitialized(gitRoot);
if (gitResult.isNew) {
log.info(`[GIT_FEATURE] Auto-initialized git repository (config: ${gitResult.configSource})`);
}
```
#### 3. LocalFileManager Refactoring (`src/utils/localFileManager.ts`)
**Simplified**: Replaced 60+ lines of inline git init logic with:
```typescript
// Use shared git initialization utility
const gitResult = await ensureGitInitialized(projectPath);
// Create initial .gitignore if this is a new repository
if (gitResult.isNew) {
const gitignoreContent = `# MCP Gas Server\n.env\n...`;
await fs.writeFile(path.join(projectPath, '.gitignore'), gitignoreContent);
}
return {
gitInitialized: gitResult.initialized,
isNew: gitResult.isNew,
repoPath: gitResult.repoPath
};
```
**Code Reduction**: ~60 lines removed, single source of truth established.
#### 4. Integration Tests (`test/integration/mcp-gas-validation/git-auto-init.test.ts` - 400+ lines)
**Test Coverage**:
- ✅ `git_feature` auto-initialization when `.git` missing
- ✅ Global git config detection and usage
- ✅ Default config fallback when no global config
- ✅ `write` tool auto-initialization during file operations
- ✅ `.gitignore` creation for new repositories
- ✅ Consistency validation across tools
- ✅ Error handling for invalid paths
**Test Scenarios**:
```typescript
describe('git_feature auto-init', () => {
it('should auto-initialize git when .git missing')
it('should use global git config if available')
it('should set default config when no global config exists')
});
describe('write tool auto-init', () => {
it('should auto-initialize git during write operation')
it('should create .gitignore when initializing new repo')
});
describe('Consistent behavior across tools', () => {
it('should produce identical git repos from write and git_feature')
});
```
