+ESLint is used for frontend code quality. Available commands:
+
+```bash
+# Lint all files (report only)
+pnpm lint
+
+# Lint and auto-fix issues
+pnpm lint:fix
+
+# Lint specific files or directories
+pnpm lint:fix app/components/base/button/

+pnpm lint:quiet
+
+# Check code complexity
+pnpm lint:complexity
+```
+
+**Important**: Always run `pnpm lint:fix` before committing. The pre-commit hook runs `lint-staged` which only lints staged files.

-# Lint Guide
-
-We use ESLint and Typescript to maintain code quality and consistency across the project.
-
-## ESLint
-
-### Common Flags
-
-**File/folder targeting**: Append paths to lint specific files or directories.
-
-```sh
-pnpm eslint [options] file.js [file.js] [dir]
-```
-
-**`--cache`**: Caches lint results for faster subsequent runs. Keep this enabled by default; only disable when you encounter unexpected lint results.
-
-**`--concurrency`**: Enables multi-threaded linting. Use `--concurrency=auto` or experiment with specific numbers to find the optimal setting for your machine. Keep this enabled when linting multiple files.
-
-- [ESLint multi-thread linting blog post](https://eslint.org/blog/2025/08/multithread-linting/)
-
-**`--fix`**: Automatically fixes auto-fixable rule violations. Always review the diff before committing to ensure no unintended changes.
-
-**`--quiet`**: Suppresses warnings and only shows errors. Useful when you want to reduce noise from existing issues.
-
-**`--suppress-all`**: Temporarily suppresses error-level violations and records them, allowing CI to pass. Treat this as an escape hatch—fix these errors when time permits.
-
-**`--prune-suppressions`**: Removes outdated suppressions after you've fixed the underlying errors.
-
-- [ESLint bulk suppressions blog post](https://eslint.org/blog/2025/04/introducing-bulk-suppressions/)
-
-### Type-Aware Linting
-
-Some ESLint rules require type information, such as [no-leaked-conditional-rendering](https://www.eslint-react.xyz/docs/rules/no-leaked-conditional-rendering). However, [typed linting via typescript-eslint](https://typescript-eslint.io/getting-started/typed-linting) is too slow for practical use, so we use [TSSLint](https://github.com/johnsoncodehk/tsslint) instead.
-
-```sh
-pnpm lint:tss
-```
-
-This command lints the entire project and is intended for final verification before committing or pushing changes.
-
-## Type Check
-
-You should be able to see suggestions from TypeScript in your editor for all open files.
-
-However, it can be useful to run the TypeScript 7 command-line (tsgo) to type check all files:
-
-```sh
-pnpm type-check:tsgo
-```
-
-Prefer using `tsgo` for type checking as it is significantly faster than the standard TypeScript compiler. Only fall back to `pnpm type-check` (which uses `tsc`) if you encounter unexpected results.
