+
+Use when the repository has `package.json`.

+## Detection
+
+Common files:
+
+```text
+package.json
+package-lock.json
+pnpm-lock.yaml
+yarn.lock
+tsconfig.json
+vite.config.*
+```
+
+## Commands
+
+Prefer existing scripts. Common defaults:
+
+```text
+INSTALL_COMMAND = npm install
+LINT_COMMAND = npm run lint
+TEST_COMMAND = npm test
+BUILD_COMMAND = npm run build
+AUDIT_COMMAND = npm audit --omit=dev --audit-level=high
