- Untrack .playwright-cli/ and ignore it + *.png; route QA artifacts to /tmp - be/fe-implementer: require git status + test output + live smoke test in every report; never trust a running server, restart fresh; say so if unfinished (fixes the false-success-report failure mode from session 1) - qa: adversarial stance (distrust self-reports, confirm features exist via /openapi.json), restart both servers + reset dev DB before testing, write expected numbers into scenarios - Add HANDOFF.md and RETROSPECTIVE.md as session docs
CalCount
A personal, self-hosted calorie counter web app with barcode scanning via phone camera and OpenFoodFacts lookup. See SPEC.md for the full spec, data model, API design, and development rules (§8 — read it before writing code).
Stack
- Backend: Python ≥3.12, FastAPI, SQLAlchemy 2, Pydantic 2, SQLite, httpx — managed with uv
- Frontend: Svelte 5 (runes) + Vite 7, zxing-wasm barcode fallback — managed with npm (Node ≥22.12)

Setup
# Backend (uv creates .venv and installs from uv.lock)
cd backend
uv sync
# Frontend
cd frontend
npm install
Run
Two terminals:
# Terminal 1 — backend on http://localhost:8000
cd backend
uv run uvicorn main:app --reload
# Terminal 2 — frontend on http://localhost:5173 (proxies /api → :8000)
cd frontend
npm run dev
The SQLite database (backend/calcount.db) is created and migrated
automatically on backend startup (backend/migrations/).
Test
cd backend && uv run pytest # backend suite
cd frontend && npm test # frontend suite (vitest)
Build
cd frontend && npm run build # production build to frontend/dist/
