PyCharm 2026.2 Links AI Agents to Live Jupyter Kernels

JetBrains PyCharm 2026.2 introduces direct Jupyter notebook control for AI agents like Claude Code and Codex, enabling persistent variable retention and model continuity across .ipynb cells through live kernel integration. The update adds environment-aware package management that automatically routes AI-generated pip/conda commands to the correct Python interpreter. Third-party marimo notebook support arrives via a new plugin, while deprecated bundled plugins (including Data Wrangler and Hugging Face) shift to Marketplace-only availability. Package management sees UI refinements like dependency trees, environment-specific installs, and VCS integration. Type checking improvements include composite type diffs and fully rendered inspection tooltips.
