NoNappa is a native macOS menu bar app that prevents sleep when the Mac lid is closed, offering customizable durations from 15 minutes to 8 hours with timed session restoration and helper-based privilege management. It requires macOS 13+ and uses XPC communication with a root-owned helper that validates commands without storing passwords.
Researchers tested Jev, an efficient classifier model, against Claude Sonnet 5 and open-weight alternatives for security classification of 100 real tool calls from production Claude Code sessions. While Jev offers speed and confidence scores, it struggles with nuanced security properties like distinguishing between output data characteristics (delta) and prerequisites for safe execution (requires), with baseline accuracy concerns when 79% of calls are inherently benign.
