-### 3. Pre-commit Hook
+### 3. Automated Workflow (This Repository)
+
+This reference repository includes **complete repomap automation**:
+
+#### Pre-commit Hook
+
+The pre-commit hook automatically regenerates `.repomap.txt` when you commit changes to code files:
+
+```yaml
+# .pre-commit-config.yaml
+repos:
+  - repo: local
+    hooks:
+      - id: repomap-update
+        name: Update repository map
+        entry: scripts/update-repomap.sh
+        language: system
+        pass_filenames: false
+        files: '\.(py|js|ts|tsx|go|sh|bash)$'
+```
+
+**Triggers on**: `.py`, `.js`, `.ts`, `.tsx`, `.go`, `.sh`, `.bash` file changes
+
+**What it does**: Runs `./scripts/update-repomap.sh` to regenerate `.repomap.txt` before commit
+
+#### CI Validation
+
+GitHub Actions workflow validates repomap is current on every push/PR:
+
+```yaml
+# .github/workflows/ci.yml
+repomap-validation:
+  runs-on: ubuntu-latest
+  steps:
+    - uses: actions/checkout@v4
+    - name: Set up Python
+      uses: actions/setup-python@v5
+      with:
+        python-version: '3.11'
+    - name: Install repomap dependencies
+      run: |
+        pip install uv
+        uv pip install tree-sitter tree-sitter-python tree-sitter-javascript \
+                       tree-sitter-typescript tree-sitter-go tree-sitter-bash
+    - name: Validate repomap is current
+      run: ./scripts/update-repomap.sh --check
+```
+
+**What it does**: Blocks merge if `.repomap.txt` is outdated
+
+#### Automation Script
+
+The `scripts/update-repomap.sh` script provides:
+
+```bash
+# Regenerate repomap
+./scripts/update-repomap.sh
+
+# Validate repomap is current (CI usage)
+./scripts/update-repomap.sh --check
+
+# Show help
+./scripts/update-repomap.sh --help
+```
+
+**Features**:
+- Clear error messages with dependency installation hints
+- Validates repomap currency for CI/CD
+- Used by pre-commit hook for auto-updates
+
+#### Manual Pre-commit Hook (Alternative)
