 ## Implementation Steps
 
 ### Task 1: Set up project structure and dependencies
-- [ ] Initialize Go module (`go mod init trip-planner`) if not already done
-- [ ] Add dependencies: `github.com/go-redis/redis/v8`, `github.com/jmoiron/sqlx`, `github.com/golang-jason/jason` (or similar)
-- [ ] Configure Docker Compose for local development (API, Redis, PostgreSQL)
-- [ ] Write basic Go project structure with go.mod, main.go, and internal packages
-- [ ] Verify `go fmt ./...` and `go vet ./...` pass
-- [ ] Run initial tests - must pass
+- [x] Initialize Go module (`go mod init trip-planner`) if not already done
+- [x] Add dependencies: `github.com/go-redis/redis/v8`, `github.com/jmoiron/sqlx` (golang-jason/jason removed, using stdlib)

 ### Task 2: Implement Yandex API client with rate limiter and circuit breaker
 - [ ] Create `internal/yandex/client.go` with Yandex API wrapper
