+## NPM Test Scripts
+
+```bash
+# Full test suite (recommended before commits)
+npm test
+
+# Individual test commands
+npm run test:schemas         # Run schema tests
+npm run test:install         # Run installation tests
+npm run validate:bundles     # Validate bundle integrity
+npm run validate:schemas     # Validate agent schemas
+npm run lint                 # ESLint check
+npm run format:check         # Prettier format check
+
+# Coverage
+npm run test:coverage        # Run tests with coverage (c8)
+```
+
+## Test Command Breakdown
+
+`npm test` runs sequentially:
+
+1. `npm run test:schemas` - Agent schema validation
+2. `npm run test:install` - Installation component tests
+3. `npm run validate:bundles` - Bundle validation
+4. `npm run validate:schemas` - Schema validation
+5. `npm run lint` - ESLint
+6. `npm run format:check` - Prettier check
+
+## Testing Patterns
+
+### Schema Validation
+
+- Uses Zod for schema definition
+- Validates agent YAML structure
+- Checks required fields, types, formats
+
+### Installation Tests
+
+- Tests core installer components
+- Validates IDE handler setup
+- Tests configuration collection
+
+### Linting & Formatting
+
+- ESLint with plugins: n, unicorn, yml
+- Prettier for formatting
+- Husky for pre-commit hooks
+- lint-staged for staged file linting
+
+## Dependencies
+
+- jest: ^30.0.4 (test runner)
+- c8: ^10.1.3 (coverage)
+- zod: ^4.1.12 (schema validation)
+- eslint: ^9.33.0
+- prettier: ^3.5.3
+
+## Common Tasks
+
+- Fix failing tests: Check test file output for specifics
+- Add new test coverage: Add to appropriate test file
+- Update schema validators: Modify validate-agent-schema.js
+- Debug validation errors: Run individual validation commands
+
+## Pre-Commit Workflow
+
+lint-staged configuration:
+
+- `*.{js,cjs,mjs}` → lint:fix, format:fix
+- `*.yaml` → eslint --fix, format:fix
+- `*.{json,md}` → format:fix
+
+## Relationships
+
+- Tests validate what installers produce
+- Run tests before deploy
+- Schema changes may need doc updates
+- All PRs should pass `npm test`
