Don’t use Claude Code or Codex unless you have these installed. First is Impeccable. It gives Claude a much stronger design system and helps it build cleaner, more intentional interfaces instead of generic AI-looking UIs. Second is Code Review. It launches specialized agents to review your changes for bugs, project-rule violations, and other issues before you ship. Third is Obsidian. It lets Claude work with your Obsidian knowledge base, including your notes, links, embeds, and other project context. Fourth is Playwright. It gives Claude an actual browser so it can navigate your app, click buttons, fill forms, take screenshots, and run end-to-end tests itself. Fifth is Supabase. It connects Claude directly to your backend so it can work with your database, authentication, storage, migrations, logs, and more. These five make Claude Code significantly better at designing, reviewing, remembering, testing, and actually building your app. Save this for later. #claudecode #coding #ai #programming #softwareengineer
