 That's it! Claude Code now has access to all CodeRunner tools:
 - **execute_python_code** - Run Python code in persistent Jupyter kernel
+- **start_python_session** - Reserve an isolated kernel for a named session
+- **list_python_sessions** - List active named sessions
+- **stop_python_session** - Stop a session and discard its kernel state
 - **navigate_and_get_all_visible_text** - Web scraping with Playwright
 - **list_skills** - List available skills (docx, xlsx, pptx, pdf, image processing, etc.)
 - **get_skill_info** - Get documentation for specific skills
 - **get_skill_file** - Read skill files and examples
 
+Pass the returned `session_id` to `execute_python_code` to keep state isolated between agents. Up to five named sessions can run concurrently.
