# Project Context

## Stack
- Node.js 22 with TypeScript 5.x
- Express.js for the API server
- Prisma ORM with PostgreSQL
- React 19 with Vite for the frontend

## Architecture
- Monorepo with pnpm workspaces
- packages/api — Express REST API
- packages/web — React SPA
- packages/shared — Shared types and utilities

## Commands
- pnpm dev — Start all services
- pnpm test — Run vitest across all packages
- pnpm lint — ESLint + Prettier check
- pnpm db:migrate — Run Prisma migrations

## Conventions
- Use barrel exports (index.ts) for public APIs
- Error responses use RFC 7807 Problem Details format
- All API endpoints require authentication except /health

# Project Rules

## Stack
- TypeScript 5.x with strict mode
- React 19 + Next.js 15 (App Router)
- Tailwind CSS v4 for styling
- Drizzle ORM for database access

## Code Standards
- Named exports only (no default exports)
- Prefer `const` assertions and satisfies operator
- Use Result<T, E> pattern for error handling
- Maximum 30 lines per function

## File Organization
- Colocate tests: `foo.ts` → `foo.test.ts`
- One component per file
- Barrel exports (index.ts) for public module APIs

## Git
- Conventional commits: feat|fix|chore|docs|test
- Squash merge feature branches
- Branch naming: type/description

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Gemini CLI, configure GEMINI.md. If you use Kilo Code, configure .kilocodemodes. Many projects include config files for multiple tools so each team member can use their preferred editor.
