概要
Provides specialized guidance and automated workflows for engineering Positron Notebooks, a custom feature-flagged React implementation that coexists with VS Code's standard notebook experience. It offers deep integration for managing notebook cell behavior, complex selection states through finite state machines, and context-key-scoped command systems. Developers can leverage this skill to navigate the architecture of kernel-notebook integration, troubleshoot execution issues, and implement UI components driven by VS Code observables while ensuring feature-flag compliance and upstream compatibility.
