jarvis	Jarvis Platform development context. Use when working on the jetrich/jarvis repository. Provides architecture knowledge, coding patterns, and component locations.

Jarvis Platform Development

Project Overview

Jarvis is a self-hosted AI assistant platform built with:

• Backend: FastAPI (Python 3.11+)
• Frontend: Next.js 14+ (App Router)
• Database: PostgreSQL with pgvector
• Plugins: Modular LLM providers and integrations

Repository: jetrich/jarvis

Key Patterns

LLM Provider Pattern

All LLM providers implement BaseLLMProvider:

# packages/plugins/jarvis_plugins/llm/base.py
class BaseLLMProvider(ABC):
    @abstractmethod
    async def generate(self, prompt: str, **kwargs) -> str: ...

    @abstractmethod
    async def stream(self, prompt: str, **kwargs) -> AsyncIterator[str]: ...

Integration Pattern

External integrations (GitHub, Calendar, etc.) follow:

# packages/plugins/jarvis_plugins/integrations/base.py
class BaseIntegration(ABC):
    @abstractmethod
    async def authenticate(self, credentials: dict) -> bool: ...

    @abstractmethod
    async def execute(self, action: str, params: dict) -> dict: ...

API Route Pattern

FastAPI routes use dependency injection:

@router.get("/items")
async def list_items(
    db: Session = Depends(get_db),
    current_user: User = Depends(get_current_user),
    service: ItemService = Depends(get_item_service)
):
    return await service.list(db, current_user.id)

Frontend Component Pattern

Use shadcn/ui + server components by default:

// Server component (default)
export default async function DashboardPage() {
  const data = await fetchData();
  return <Dashboard data={data} />;
}

// Client component (when needed)
('use client');
export function InteractiveWidget() {
  const [state, setState] = useState();
  // ...
}
