# ln-741-linter-configurator

**Type:** L3 Worker
**Category:** 7XX Project Bootstrap

Configures code linting, formatting, and type checking tools for TypeScript, Python, and .NET projects.

---

## Purpose & Scope

**Does:**
- Detects which linter stack to configure based on project type
- Checks for existing linter configurations
- Generates appropriate config files from templates
- Installs required dependencies (always latest versions, no pinning)
- Generates unified lint script (`scripts/lint.sh`)
- Verifies all linters run without errors

**Does NOT:**
- Configure pre-commit hooks (separate worker)
- Set up test infrastructure (separate worker)
- Modify source code

## Supported Stacks

| Technology | Linter | Type Checker | Formatter | Config Files |
|------------|--------|-------------|-----------|--------------|
| TypeScript | ESLint 9+ (flat config) | TypeScript (tsc) | Prettier | `eslint.config.ts`, `.prettierrc` |
| .NET | Roslyn Analyzers | Roslyn | dotnet format | `.editorconfig`, `Directory.Build.props` |
| Python | Ruff | mypy | Ruff (built-in) | `ruff.toml`, `mypy.toml` (or `pyproject.toml`) |

## Phase 1: Check Existing Configuration

Before generating configs, check what already exists.

**Files to Check:**

| Stack | Config Files | Glob Pattern |
|-------|--------------|--------------|
| TypeScript | ESLint config | `eslint.config.*`, `.eslintrc*` |
| TypeScript | Prettier config | `.prettierrc*`, `prettier.config.*` |
| .NET | Editor config | `.editorconfig` |
| .NET | Build props | `Directory.Build.props` |
