Set **custom instructions** that Agent follows in every project, and create reusable **skills** that Agent loads on demand for specific tasks. You manage both in **Workspace Settings** > **Customization**. The Agent customization tab where you add workspace instructions and skills Learn more about [Agent Customization](/references/agent/agent-customization). ## Platform ### Block malicious packages with Package Firewall Replit now blocks malicious and compromised software packages before they ever reach your app. Package Firewall checks every install across common package managers and stops harmful dependencies automatically. It is on by default, and Agent adapts its plan to use safer alternatives when something is blocked. A blocked malicious package message from Package Firewall Learn more about [Package Firewall](/references/security/package-firewall). ## Workspace ### Faster slide import and export PowerPoint and Google Slides exports are three to ten times faster, large photo-heavy decks no longer produce oversized PDF files, and you can jump to a Google Slides export in one selection. The Slides toolbar with the Export menu open, showing options to export the deck as PDF, PowerPoint, or Google Slides Learn more about [exporting slide decks](/references/artifact-types/slide-decks#exporting). ### Add visual references when you generate media on Canvas When you generate an image, video, or vector graphic on Canvas, you can now attach things already on your board as visual references. Pick a frame, a note, or an image and Agent uses it to guide the result, so your generated media matches the look of your project. The Generate media form on Canvas with the plus menu open, showing the Upload file and Select canvas elements options and the model dropdown set to Nano Banana Pro ChatGPT Images 2.0 does not support uploads at the moment. Switch the model, for example to Nano Banana Pro, to attach visual references.

A new **Production Alerts** setting decides whether Replit emails you about uptime incidents, security vulnerabilities in your dependencies, and language model updates. If a published app uses an out-of-date model, Replit also prepares a draft task so you can upgrade with one review. The Production Alerts section in notification settings, showing the production alert emails toggle on and the security alerts severity dropdown expanded Learn more about [notification settings](/references/editor/user-settings#notifications).
