-You need a GitHub PAT with `read:packages` permission.
+## Code Standards & Conventions
+
+**IMPORTANT:** Always study existing code in the relevant area before making changes. Match the existing style exactly.
+
+### Backend (C#)
+- Follow Microsoft C# Coding Conventions
+- Use nullable reference types (`<Nullable>enable</Nullable>`)
+- Add XML documentation comments for public APIs
+- Use meaningful names - avoid abbreviations unless widely understood
+- Keep services focused - single responsibility principle
+- New integrations go under `Features/` subdirectories (e.g., `Infrastructure/Features/Arr/`)
+
+### Frontend (TypeScript/Angular)
+- All components must be **standalone** with **ChangeDetectionStrategy.OnPush**
+- Use `input()` / `output()` function APIs (not `@Input()` / `@Output()` decorators)
+- Use Angular **signals** for reactive state (`signal()`, `computed()`, `effect()`)
+- Follow the 3-layer SCSS design system (`_variables` -> `_tokens` -> `_themes`)
+- **Do not introduce external UI frameworks** (no PrimeNG, Material, Tailwind, etc.)
+- Component naming: `{feature}.component.ts`
+- Service naming: `{feature}.service.ts`
+- **Look at similar existing components before creating new ones**
+
+### Testing
+- **Backend**: xUnit + NSubstitute + Shouldly
+- Always use **NSubstitute** for mocking (Moq is being phased out)
+- Write unit tests for new features and bug fixes
+- Use descriptive test names that explain what is being tested
+- No frontend unit tests currently
+
+### Git Commit Messages
+- Use clear, descriptive messages in imperative mood
+- Examples: "Add Discord notification support", "Fix memory leak in download client polling"
+- Reference issue numbers when applicable: "Fix #123: Handle null response from Radarr API"
+

-- Document them if confirmed
-- Consider if they should be added to this guide
-
 ## Database Migrations
 
-Cleanuparr uses two separate database contexts:
-- **DataContext**: Main application data
-- **EventsContext**: Event logging and audit trail
-
-### Creating Migrations
-From the `code` directory:
+Three separate database contexts, all commands run from the `code` directory:
 
 ```bash
-# Data migrations
+# Data migrations (DataContext)
 make migrate-data name=YourMigrationName
 
-# Events migrations
+# Events migrations (EventsContext)
 make migrate-events name=YourMigrationName
-```
 
-Example:
-```bash
-make migrate-data name=AddDownloadClientConfig
-make migrate-events name=AddStrikeEvents
+# Users migrations (UsersContext)
+make migrate-users name=YourMigrationName
 ```

-## Working with Claude - IMPORTANT
-
-### Core Principles
-1. **When in doubt, ASK** - Don't assume, clarify with the maintainer first
-2. **Don't break existing functionality** - Everything is important and needs to work
-3. **Follow existing coding style** - Study the codebase patterns before making changes
-4. **Use current coding standards** - If you want to introduce something new, ask first
-
-### When Modifying Code
-- **ALWAYS read existing files before suggesting changes**
-- Understand the current architecture and patterns
-- Prefer editing existing files over creating new ones
-- Follow the established conventions in the codebase exactly
-- Test changes locally when possible
-- **If you're unsure about an approach, ask before implementing**
-
-### When Adding Features
-- Review similar existing features first to understand patterns
-- Maintain consistency with existing UI/UX patterns
-- Update both backend and frontend together
-- Add/update documentation
-- Consider backwards compatibility
-- **Ask about architectural decisions before implementing new patterns**
-
-### When Fixing Bugs
-- Understand the root cause before proposing a fix
-- **Be careful not to break other functionality** - test related areas
-- Add tests to prevent regression
-- Update relevant documentation if behavior changes
-- Consider if other parts of the codebase might have similar issues
-- **Flag any potential gotchas or issues you discover**
-
-## Notes
+## Key Gotchas
 
+- **Custom glassmorphism design system** - Do not introduce external UI frameworks (no PrimeNG, Material, Tailwind)
+- **All frontend components** must be standalone with OnPush change detection
+- **Database migrations** require awareness of all three contexts (Data, Events, Users)
+- **Malware blocker** is a critical security feature - changes require careful testing
+- **Cross-seed integration** allows keeping torrents that are actively seeding
+- **Real-time updates** use SignalR - maintain websocket patterns when adding features
+- Use `@ng-icons/core` + `@ng-icons/tabler-icons` for icons (NOT `angular-tabler-icons` which doesn't support Angular 21)
+- **Sidebar** stays dark purple in both themes - uses sidebar-specific CSS variables
 - The project uses **Clean Architecture** - respect layer boundaries
-- Database migrations require both contexts - don't forget EventsContext
-- Frontend uses a **custom glassmorphism design system** - don't introduce external UI frameworks (no PrimeNG, Material, etc.)
-- All frontend components are **standalone** with **OnPush** change detection
-- All downloads from *arr apps are processed through a **strike system**
-- The malware blocker is a critical security feature - changes require careful testing
-- Cross-seed integration allows keeping torrents that are actively seeding
-- Real-time updates use **SignalR** - maintain websocket patterns when adding features
+- **Settings dirty tracking** uses JSON snapshot comparison (`buildSnapshot()` + `hasPendingChanges()`)

-Cleanuparr is a tool for automating the cleanup of unwanted or blocked files in Sonarr, Radarr, and supported download clients like qBittorrent. It removes incomplete or blocked downloads, updates queues, and enforces blacklists or whitelists to manage file selection. After removing blocked content, Cleanuparr can also trigger a search to replace the deleted shows/movies.
+</div>
+
+Cleanuparr is an advanced download manager for the Servarr ecosystem. It works with Sonarr, Radarr, Lidarr, Readarr, and Whisparr alongside download clients like qBittorrent, Transmission, and Deluge. Beyond cleaning up stalled, blocked, and malicious downloads, it searches for missing content and quality upgrades, manages seeding, and removes orphaned files.
 
 Cleanuparr was created primarily to address malicious files, such as `*.lnk` or `*.zipx`, that were getting stuck in Sonarr/Radarr and required manual intervention. Some of the reddit posts that made Cleanuparr come to life can be found [here](https://www.reddit.com/r/sonarr/comments/1gqnx16/psa_sonarr_downloaded_a_virus/), [here](https://www.reddit.com/r/sonarr/comments/1gqwklr/sonar_downloaded_a_mkv_file_which_looked_like_a/), [here](https://www.reddit.com/r/sonarr/comments/1gpw2wa/downloaded_waiting_to_import/) and [here](https://www.reddit.com/r/sonarr/comments/1gpi344/downloads_not_importing_no_files_found/).
