The Content OS plugin streamlines the process of drafting and publishing LinkedIn posts directly from your notes. It eliminates context switching by providing an integrated modal where you can compose content, monitor character count in real time, and push updates straight to LinkedIn. Tokens are handled securely with OAuth 2.0 and stored locally, ensuring privacy while maintaining authentication reliability. The interface is simple, offering both a ribbon button and command palette access for quick posting. Settings allow you to configure save locations, enable dev mode, and adjust logging detail when troubleshooting. Behind the scenes, the plugin uses LinkedIn's v2 API for user verification and content publishing, supporting full token validation before every request.
