+# Scripts
+
+This directory contains utility scripts for managing configuration, credentials, and development workflows.
+
+## Documentation Scripts
+
+### check-docs-sync.sh
+
+Verifies that generated documentation is synchronized with code changes, preventing documentation drift.
+
+**Purpose**: Ensures developers keep generated documentation in sync with code by failing CI if docs are out of date.
+
+**Usage**:
+
+```bash
+./script/check-docs-sync.sh
+```
+
+**Configuration**:
+
+Set environment variables to customize behavior:
+
+```bash
+# Set documentation generation command (default: npm run docs:generate)
+export DOC_GENERATE_CMD="pnpm run docs:generate"
+
+# Set documentation directory (default: docs)
+export DOCS_DIR="documentation"
+
+# Run the checker
+./script/check-docs-sync.sh
+```
+
+**How It Works**:
+
+1. Creates a backup of current documentation
+2. Runs the documentation generation command
+3. Compares generated docs with the original
+4. Fails with helpful error message if differences are found
+
+**Example Output**:
+
+Success:
+
+```
+📚 Checking documentation sync...
+📝 Generating documentation...
+🔍 Comparing documentation...
+✅ Documentation is in sync!
+```
+
+Failure:
+
+```
+📚 Checking documentation sync...
+📝 Generating documentation...
+🔍 Comparing documentation...
+❌ ERROR: Generated documentation is out of sync!
+
+Differences found:
+...
+
+Please run the following command and commit the changes:
+  npm run docs:generate
+
+Or use the unified command (if available):
+  npm run docs:all
+```
+
+**CI Integration**:
+
+Add to `.github/workflows/ci.yml`:
+
+```yaml
+- name: Check documentation sync
+  run: ./script/check-docs-sync.sh
+```
+
+Add to `package.json`:
+
+```json
+{
+  "scripts": {
+    "docs:generate": "your-doc-generator-command",
+    "docs:check": "./script/check-docs-sync.sh",
+    "docs:all": "npm run docs:generate && npm run docs:check"
+  }
+}
+```
+
+**Use Cases**:
+
+- Projects with auto-generated API documentation
+- Template-based documentation systems
+- Schema-driven documentation
+- Any project where docs are generated from code/metadata
+
+**Benefits**:
+
+- ✅ Prevents stale documentation
+- ✅ No manual doc update reminders needed
+- ✅ Catches issues before merge
+- ✅ Clear error messages with fix commands
+- ✅ Lightweight (simple bash script, no dependencies)
