This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Structure

This is a Turbo monorepo containing multiple applications and shared packages:

Applications (apps/)

• web/ - Next.js web application
• mcp/ - Model Context Protocol server

Development Commands

Root Level (Monorepo)

• bun run dev - Start all applications in development mode
• bun run build - Build all applications
• bun run check-types - Run TypeScript checks across all apps
• bun run format-lint - Format and lint code using Biome

Web Application (apps/web/)

• bun run dev - Start Next.js development server
• bun run build - Build Next.js application
• bun run lint - Run Next.js linting

Architecture Overview

Core Technology Stack

• Runtime: Next.js (web)
• Framework: Next.js (web)
• Language: TypeScript throughout
• Package Manager: Bun
• Monorepo: Turbo
• Authentication: Better Auth
• Monitoring: Sentry

API Application (Primary Backend)

The API serves as the core backend with these key features:

Key API Routes

• /v3/documents - CRUD operations for documents/memories
• /v3/search - Semantic search across indexed content
• /v3/connections - External service integrations (Google Drive, Notion, OneDrive)
• /v3/settings - Organization and user settings
• /v3/analytics - Usage analytics and reporting
• /api/auth/* - Authentication endpoints

Web Application

Next.js application providing user interface for:

Key Libraries & Dependencies

Shared Dependencies

• better-auth - Authentication system with organization support
• drizzle-orm - Database ORM
• zod - Schema validation
• hono - Web framework (API & MCP)
• @sentry/* - Error monitoring
• turbo - Monorepo build system

Web-Specific

• next - React framework
• @radix-ui/* - UI components
• @tanstack/react-query - Data fetching
• recharts - Analytics visualization

Development Workflow

Content Processing Pipeline

All content goes through the IngestContentWorkflow which handles:

• Content type detection and extraction
• AI-powered summarization and automatic tagging
• Vector embedding generation using Cloudflare AI
• Chunking for semantic search optimization
• Space relationship management

Environment Configuration

• Uses wrangler.jsonc for Cloudflare Workers configuration
• Supports staging and production environments
• Requires Cloudflare bindings: Hyperdrive (DB), AI, KV storage, Workflows
• Cron triggers every 4 hours for connection imports

Error Handling & Monitoring

• HTTPException for consistent API error responses
• Sentry integration with user and organization context
• Custom logging that filters analytics noise

Code Quality & Standards

Linting & Formatting

• Biome used for linting and formatting across the monorepo
• Run bun run format-lint to format and lint all code
• Configuration in biome.json at repository root

TypeScript

• Strict TypeScript configuration with @total-typescript/tsconfig
• Type checking with bun run check-types
• Cloudflare Workers type generation with cf-typegen

Database Management

• Drizzle ORM with schema located in shared packages
• Database migrations handled through Drizzle Kit
• Schema types automatically generated and shared

Security & Best Practices

Authentication

• Better Auth handles user authentication and organization management
• API key authentication for external access
• Role-based access control within organizations

Data Handling

• Content hashing to prevent duplicate processing
• Secure handling of external service credentials
• Automatic content type detection and validation

Deployment

• Cloudflare Workers for scalable serverless deployment
• Source map uploads to Sentry for production debugging
• Environment-specific configuration management
