 **라고할때살걸** — Korean trading strategy backtesting platform (SMA, RSI, MACD, Bollinger, EMA, Buy&Hold). Supports portfolios, DCA, rebalancing.
 
-**Stack:** Python 3.11 / FastAPI | TypeScript / React / Vite | MySQL 8.0 (prod) / SQLite (tests) | Docker Compose | Jenkins CI/CD

 ## Architecture
 
 **BE flow:** `FastAPI Endpoint → PortfolioManagerService → BacktestEngine / StrategyService / StockRepository → UnifiedDataService`
 
 **FE (Feature-Sliced Design):** `shared` ← `features` ← `pages` (no reverse imports). State: Zustand (global) + `useReducer` (forms). UI: shadcn/ui + Tailwind + Recharts.
 
-**DB:** `stocks`, `daily_prices`, `stock_news` (see `database/schema.sql`)
+**DB schema:** see `database/schema.sql`
 
 **API:** POST `/api/v1/backtest` — main endpoint. Errors: `@handle_portfolio_errors` decorator.

 ## Sub-Agent Usage
 
-When working on this codebase, **actively use specialized sub-agents** for better quality:
-- **`frontend-developer`** for React/TypeScript component changes
-- **`python-pro` / `fastapi-pro`** for BE service/API changes
-- **`test-automator`** for writing tests
-- **`code-reviewer` / `architect-review`** for reviewing changes before finalizing
-- **`debugger`** when encountering errors
-- **`Explore`** agent for broad codebase research
+- **`Explore`** for broad codebase research (where does X live, how is Y wired)
+- **`Plan`** for designing multi-step changes before writing code
+- **`general-purpose`** for multi-step research/edit tasks that need their own context
 
 Always verify changes in Docker containers (`docker compose exec`) before declaring work complete.
 
 ## Testing
 
 - **BE markers:** `@pytest.mark.unit` (no DB), `@pytest.mark.integration` (DB), `@pytest.mark.external` (real API)
 - **FE:** Vitest + React Testing Library; Playwright for E2E
-- 141 BE unit tests, 94+ FE tests
