These are recommended PostToolUse automations to keep RN/Expo code healthy. Wire them in your hook runtime (or run manually); adapt commands to your package manager. ## Suggested PostToolUse checks (on edit of *.ts/*.tsx) - **Type check:** `tsc --noEmit` — catch type errors early. - **Lint:** `npx expo lint` (uses `eslint-config-expo`; flat config `eslint.config.js` is the default from SDK 53+). - **Format:** `prettier --write` on changed files. ## Pre-release / periodic - `npx expo-doctor` — validates Expo/native dependency health and config. - `npx expo install --check` — keeps native deps aligned with the installed Expo SDK. - `npm audit` — dependency vulnerability scan. ## Notes - Do not run heavy native builds inside fast edit hooks; keep edit-time hooks to typecheck/lint/format. - Reserve `eas build` / E2E for explicit commands or CI, not per-edit automation. - Keep these consistent with ECC hook runtime controls (`ECC_HOOK_PROFILE`, `ECC_DISABLED_HOOKS`).
