# Project Instructions

## Architecture
- Monorepo with apps/ and packages/ directories
- Each app is a standalone Next.js deployment
- Shared packages use TypeScript project references

## Code Standards
- TypeScript strict mode everywhere
- Use Zod for runtime validation at API boundaries
- Prefer server components; use "use client" only when needed
- All database queries go through the data-access layer

## Testing
- Unit tests with Vitest for business logic
- Integration tests for API routes
- E2E tests with Playwright for critical user flows

## Deployment
- Preview deployments on every PR
- Production deploys from main branch only
- Environment variables managed via .env.local (never committed)

# Project Rules

## Stack
- Go 1.23 with Chi router
- PostgreSQL 16 with pgx driver
- Redis for caching and rate limiting

## Commands
- make dev — Start with hot reload (air)
- make test — Run go test ./...
- make lint — Run golangci-lint
- make migrate — Run goose migrations

## Conventions
- Use context.Context as first param in all functions
- Structured logging with slog
- Errors wrap with fmt.Errorf("funcName: %w", err)
- Table-driven tests with t.Run subtests

KEY DIFFERENCES

1. IDE integration

Google Antigravity: Supported. Warp: Terminal.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Google Antigravity, configure AGENTS.md. If you use Warp, configure AGENTS.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
