Project config	✓	✓
Subdirectory scoping	✓	✗	Config files in subdirectories that apply only to that subtree
File inclusion / imports	✓	✗	Ability to include or reference other files from config
Ignore file	.claudeignore	.clineignore
IDE integration	CLI	✓
Schema / structure	Free-form (Markdown)	Free-form (Markdown)	Whether config uses structured schema or free-form content
Git committed	✓	✓	Whether primary config files are intended to be version-controlled

SIDE-BY-SIDE CODE SAMPLES

Claude Code

CLAUDE.md

markdown

# Project Name

> TypeScript + React monorepo. Deployed on Vercel.

## Code Style

- TypeScript strict mode — no `any`, no `ts-ignore`
- Named exports only (no default exports)
- Prefer functional patterns: map/filter/reduce over for-loops
- Error handling: use Result<T, E> from `src/lib/result.ts`

## Architecture

- `src/routes/`   — Route handlers (thin layer, delegates to services)
- `src/services/`  — Business logic, one file per domain entity
- `src/db/`        — Drizzle ORM schema and query helpers
- `src/lib/`       — Shared utilities (logger, result type, validation)

## Commands

```bash
pnpm install          # Install dependencies
pnpm dev              # Start dev server (port 3000)
pnpm test             # Run Vitest suite
pnpm test:e2e         # Run Playwright tests
pnpm lint             # ESLint + Prettier check
pnpm db:migrate       # Run pending Drizzle migrations
```

## Git Conventions

- Conventional Commits: `feat:`, `fix:`, `chore:`, `docs:`
- Branch naming: `feat/short-description`, `fix/issue-number`
- Squash merge to main; delete branches after merge

## Notes

- The `src/legacy/` directory is being migrated. Do not add new code there.
- All dates are stored as UTC. Never use local time.

# React Component Conventions

- Use functional components with TypeScript interfaces for props
- Export components as named exports
- Use Tailwind CSS for all styling
- Keep components under 150 lines; extract sub-components when larger

KEY DIFFERENCES

1. Subdirectory scoping

Claude Code: Supported. Cline: Not supported.

2. File inclusion / imports

Claude Code: Supported. Cline: Not supported.

3. Ignore file

Claude Code: .claudeignore. Cline: .clineignore.

4. IDE integration

Claude Code: CLI. Cline: Supported.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Claude Code, configure CLAUDE.md. If you use Cline, configure .clinerules/*.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
