Generic Constructor-Pattern agent kit for Claude Code. Zero personal data, fully English, MIT-licensed. Contents: - 34 reusable blocks (baseline, rules, stack/deploy/domain/api/scraper) - 14 cross-project agent manifests (code/ml/infra/researcher/critic/...) - 6 portable skills (/new-agent, /research, /test-gen, /debug-deep, /pr-review, /refactor) - Rust assembler (single binary, ~500 KB) - 3 hooks (auto-reassemble, pre-commit validate, no-hand-edit) - install.sh (idempotent, cargo-builds on first run) - MIT LICENSE All 6 sanity greps pass: 0 Russian text, 0 specific project names, 0 incident numbers, 0 user paths, 0 hardcoded IPs, 0 API keys. cargo check + assemble --validate: both pass on 14 manifests.

# STACK — FastAPI + async SQLAlchemy 2.0 + PostgreSQL
|
|
|
|
Use when the project is Python-locked (existing codebase) or needs Python-exclusive bindings. Justify on first touch.
|
|
|
|
**Core versions:** FastAPI ≥ 0.110, SQLAlchemy 2.0 async style (`AsyncSession`, `select()`, `await session.execute()` — NOT the legacy `Query` API), Pydantic v2 (NOT v1), Alembic for migrations, pytest-asyncio for tests.
|
|
|
|
**Session pattern:**
|
|
```python
|
|
async def get_db() -> AsyncIterator[AsyncSession]:
|
|
async with async_session() as session:
|
|
yield session # FastAPI unwinds on response
|
|
|
|
@router.get("/x")
|
|
async def handler(db: Annotated[AsyncSession, Depends(get_db)]): ...
|
|
```
|
|
Dependency injection via `Depends()` — never thread a session through global state.
|
|
|
|
**Commit rule:** inside an `@asynccontextmanager` block, do NOT call `session.commit()` in the request path — let the context manager close the txn. Mixing the two causes the "RuntimeError: Session is already flushing" storm.
|
|
|
|
**Migrations:** Alembic only. No raw `ALTER TABLE` on prod. Migrations checked into git alongside the model change in the same commit.
|
|
|
|
**Common security-debt checklist:** on touch, fix the known issues — default SECRET_KEY, missing CSRF, rate-limit not applied, N+1 in paginated queries. Don't paper over.
|
|
|
|
**Deploy:** Docker + nginx reverse proxy (typical pattern: app container on internal port, nginx on public port). Shared-host coordination: check cross-project impact before apt/systemd/nginx changes.
|
|
|
|
**Forbidden:** `session.commit()` in request handler if `get_db` is contextmanager-based; raw SQL on prod; committing `.env` (DB credentials, API tokens); deprecated model aliases — pin the dated model string.
