+# Test Coverage Analyzer
+
+Analyze test coverage metrics, identify untested code paths, and generate comprehensive coverage reports.
+
+## Capabilities
+
+- **Line coverage** - Which lines are executed
+- **Branch coverage** - Which branches taken
+- **Function coverage** - Which functions called
+- **Statement coverage** - Which statements executed
+- **Uncovered code identification** - Find gaps
+- **Coverage trends** - Track over time
+- **Threshold enforcement** - Minimum coverage requirements
+
+## Usage
+
+```bash
+/analyze-coverage                    # Analyze current coverage
+/analyze-coverage --threshold 80     # Enforce 80% minimum
+/analyze-coverage --detailed         # Detailed report
+/cov                                 # Shortcut
+```
+
+## Report Format

+Code Coverage Report
+====================
+Overall Coverage: 78.5%
+
+By File:
+  src/utils/validator.js     95.2%  
+  src/api/users.js           82.1%  
+  src/api/products.js        68.4%  ️
+  src/services/payment.js    45.7%  
+
+By Type:
+  Lines:      78.5% (1,571 / 2,000)
+  Branches:   72.3% (289 / 400)
+  Functions:  85.1% (85 / 100)
+  Statements: 78.2% (1,563 / 2,000)
+
+Uncovered Lines:
+  src/api/products.js:45-52 (error handling)
+  src/api/products.js:78-82 (edge case)
+  src/services/payment.js:23-67 (refund logic)
+
+Recommendations:
+  1. Add tests for payment service refund logic
+  2. Test error handling in products API
+  3. Cover edge cases in product filtering
+```
+
+## Best Practices
+
+- Aim for 80%+ coverage
+- 100% coverage != bug-free
+- Focus on critical paths
+- Cover edge cases
+- Test error handling
+- Track coverage trends
