Breathe CLI — Resonance Breathing Skill

Skill by ara.so — Devtools Skills collection.

Breathe CLI is a terminal application for paced resonance breathing at ~6 breaths per minute, designed for vagal tone training and improving heart rate variability (HRV). It's a single Python file with no dependencies, supporting macOS and Windows 11. The app provides audio cues, visual progress bars, and session logging for daily practice.

What It Does

Breathe CLI paces slow breathing at resonance frequency (typically 4.5-6.5 bpm) to amplify respiratory sinus arrhythmia (RSA) and improve cardiac vagal tone. It's based on clinical research showing benefits for heart failure patients and autonomic balance. The app includes presets for different times of day and allows custom breath ratios.
