• Generates framework-specific code edits for React, Vue, Angular, Next.js, and Svelte
• Writes code patches directly to local project files in the developer environment
• Produces CSS/style updates and component-aware refactorings from DOM and style analysis
• Provides a CLI entrypoint (npx stagewise or pnpm dlx stagewise) to start the agent
• Integrates with external AI agents via an open agent interface (e.g., Cursor, Copilot, Windsurf)
• Exposes a plugin system to customize and extend functionality and workflows
• Performs real-time code analysis and suggests frontend optimizations while editing
