# Project Rules
## Overview
E-commerce platform built with Go microservices and React frontend.
All services communicate via gRPC with Protocol Buffers.
## Go Services
- Follow standard Go project layout (cmd/, internal/, pkg/)
- Use structured logging with slog (not log or fmt.Println)
- Error handling: always wrap errors with fmt.Errorf("%w", err)
- Database access through repository pattern in internal/repo/
- All public functions must have godoc comments
## API Design
- Proto files live in proto/ directory with buf for linting
- Use field masks for partial updates
- Pagination via cursor-based tokens, not offset
## Testing
- Table-driven tests for all business logic
- Use testcontainers-go for integration tests
- Minimum 80% coverage on internal/ packages
- Mock external services with gomock interfaces
## Do Not
- Use global variables or init() functions
- Import internal packages across service boundaries
- Commit generated .pb.go files (CI generates them)

# Backend Rules
## Stack
- Python 3.12 with FastAPI
- SQLAlchemy 2.0 with async sessions
- Alembic for migrations
- pytest for testing
## Conventions
- Use type hints on all function signatures
- Async endpoints by default
- Pydantic v2 models for request/response schemas
- Repository pattern for database access
## File Structure
- app/api/routes/ — API endpoints
- app/models/ — SQLAlchemy models
- app/schemas/ — Pydantic schemas
- app/services/ — Business logic

WHICH SHOULD I USE?
Choose based on your IDE/CLI preference. If you use Gemini Code Assist, configure GEMINI.md. If you use Void, configure .void/rules/*.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
