+# Compass Calendar Development Instructions
+
+Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here.
+
+## Working Effectively
+
+### Initial Setup
+
+- Install dependencies: `yarn install --frozen-lockfile --network-timeout 300000`
+  - Takes ~3.5 minutes. NEVER CANCEL. Set timeout to 10+ minutes.
+- Copy environment template: `cp packages/backend/.env.example packages/backend/.env`
+
+### Development Servers
+
+- **CRITICAL**: The backend requires external service credentials (Google OAuth, Supertokens, MongoDB) to run properly
+- **Web Development** (RECOMMENDED for coding):
+  - `yarn dev:web` - Takes ~10 seconds to build. Serves on http://localhost:9080/
+  - Frontend works standalone without backend services
+- **Backend Development** (requires full setup):
+  - `yarn dev:backend` - Fails without proper .env configuration
+  - Needs: Google Cloud OAuth credentials, Supertokens account, MongoDB connection
+
+### Testing
+
+- **Core tests**: `yarn test:core` - Takes ~2 seconds. NEVER CANCEL. Always passes.
+- **Web tests**: `yarn test:web` - Takes ~15 seconds. NEVER CANCEL. 27/28 tests pass.
+- **Full test suite**: `yarn test` - Takes ~18 seconds but FAILS in restricted environments due to MongoDB binary download from fastdl.mongodb.org
+  - Use individual package tests instead: `yarn test:core` and `yarn test:web`
+
+### Building
+
+- **CLI Tool**: `yarn cli --help` - Takes ~3 seconds. Lists all available commands.
+- **Web Build**: `yarn cli build web --environment staging --clientId "test-client-id"`
+- **Node Build**: `yarn cli build nodePckgs --environment staging`
+- Both builds require valid environment configuration
+
+### Linting
+
+- `npx eslint . --fix` - Takes ~15 seconds. NEVER CANCEL.
+- Expect ~186 style errors (normal for this codebase)
+- No workspace-level lint command available
+
+## Validation
+
+### Manual Testing Requirements
+
+- **ALWAYS** test the web application by starting `yarn dev:web` and navigating to http://localhost:9080/
+- **ALWAYS** verify the login page loads correctly (shows "The gangway lowers only for the chosen" message)
+- **DO NOT** attempt to test login functionality without proper backend setup
+- **ALWAYS** run `yarn test:core` and `yarn test:web` after making changes
+- **ALWAYS** run `npx eslint . --fix` before completing work
+
+### Screenshots and UI Validation
+
+- Web application successfully loads and displays professional login interface
+- Login page URL: http://localhost:9080/login?reason=gauth-session-expired
+- Expected: Dark themed login form with email input and "OK" button
+
+## Project Structure
+
+### Packages Overview
+
+- `@compass/backend` - Express.js REST API with MongoDB, Google Calendar sync, WebSocket support
+- `@compass/web` - React/TypeScript frontend with Redux, styled-components, webpack bundling
+- `@compass/core` - Shared utilities, types, and business logic
+- `@compass/scripts` - CLI tools for building, database operations, user management

+
+## Environment Requirements
+
+### Required for Full Development
+
+- Node.js >=18.18.0 (specified in package.json engines)
+- Yarn package manager (lockfile format)
+- Google Cloud Project with OAuth 2.0 credentials
+- Supertokens account for user session management
+- MongoDB database (cloud or local)
+
+### Optional Services
+
+- Kit.com account for email integration
+- NGrok account for local tunneling
+
+### Critical Environment Variables (backend/.env)
+
+```bash
+# Required for backend to start
+BASEURL=http://localhost:3000/api
+CLIENT_ID=YOUR_GOOGLE_OAUTH_CLIENT_ID
+CLIENT_SECRET=YOUR_GOOGLE_OAUTH_SECRET
+SUPERTOKENS_URI=YOUR_SUPERTOKENS_INSTANCE_URL
+SUPERTOKENS_KEY=YOUR_SUPERTOKENS_API_KEY
+MONGO_URI=YOUR_MONGODB_CONNECTION_STRING
+
+# Required for web development
+PORT=3000
+NODE_ENV=development
+```
+
+## Common Tasks & Timing
+
+### Repository Operations
+
+- `yarn install` - 3.5 minutes (NEVER CANCEL, set 10+ minute timeout)
+- `yarn test:core` - 2 seconds (always passes)
+- `yarn test:web` - 15 seconds (27/28 tests pass)
+- `yarn dev:web` - 10 seconds to start (always works)
+- `yarn cli --help` - 3 seconds (shows available commands)
+
+### Development Workflow
+
+1. **Start Development**: `yarn dev:web` (frontend only, always works)
+2. **Run Tests**: `yarn test:core && yarn test:web` (skips problematic backend tests)
+3. **Check Code Style**: `npx eslint . --fix` (expect style warnings)
+4. **Manual Validation**: Open http://localhost:9080/ and verify login page loads
+
+### CI/CD Integration
+
+- GitHub Actions runs `yarn install` and `yarn test` on Node.js 20
+- Tests fail in CI due to MongoDB network restrictions (known limitation)
+- Linting and build validation happens in CI pipeline
+
+## Troubleshooting
+
+### Common Issues
+
+- **MongoDB download failures**: Use `yarn test:core` and `yarn test:web` instead of `yarn test`
+- **Backend won't start**: Missing environment variables, use web-only development
+- **Build timeouts**: All build operations need 10+ minute timeouts
+- **Test failures**: Expected in restricted network environments
+
+### Network Limitations
+
+- MongoDB binary downloads blocked in some environments
+- Google Fonts and external resources may be blocked
+- Backend services require internet connectivity for OAuth and database
+
+### Workarounds
+
+- Develop frontend-only using `yarn dev:web` for most coding tasks
+- Use individual test commands instead of full test suite
+- Mock external services for backend development when credentials unavailable
+
+## Package Scripts Reference
+
+### Root Level Commands
+
+- `yarn cli [command]` - Access CLI tools for build, seed, delete operations
+- `yarn dev:web` - Start webpack dev server (recommended)
+- `yarn dev:backend` - Start backend server (requires full environment)
+- `yarn test` - Run all tests (fails in restricted environments)
+- `yarn test:core` - Run core package tests only (reliable)
+- `yarn test:web` - Run web package tests only (mostly reliable)
+
+### Individual Package Commands
+
+- Core: Basic test and lint-fix scripts (lint-fix does nothing)
+- Backend: No individual scripts defined
+- Web: No individual scripts defined
+- Scripts: CLI entry point and utilities
+
+Always prioritize frontend development with `yarn dev:web` when backend services are unavailable.
