git-grass — Open-Source AI Terminal Detox & Proof-of-Nature Git Daemon A developer built git-grass, an open-source Python CLI and Git pre-commit hook that locks commits after two hours of continuous coding until the user submits a photo proving they touched real grass. The tool runs a fully offline computer-vision pipeline on CPU in about 80 milliseconds, using Excess Green Index and VARI chlorophyll detection plus organic-texture entropy filters to reject IDE screenshots and dark-theme monitor images. It is built with Python 3, Click, Rich, Pillow, NumPy, and ONNX Runtime, and stores lockout state locally in ~/.git-grass/state.json. This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass https://dev.to/challenges/hacktoberfest-week1-2026-10-05 git-grass is a developer wellness CLI and Git pre-commit daemon powered by on-device open-weight computer vision. It actively fights developer burnout by monitoring active screen time and locking Git commits until you physically step away from your desk, go outside, and provide photo proof that you touched real grass, lawn turf, or autumn foliage. git commit / git push if you code continuously for over 2 hours without an outdoor break. Here is git-grass blocking a commit during a long coding session, and then unlocking immediately after verifying real grass: bash bash $ git commit -m "fix: typo in function" ╔════════════════════════════════════════════════════════════╗ ║ 🔒 GIT COMMITS LOCKED ║ ║ ║ ║ You have been coding for too long without outdoors time ║ ║ Git commits are paused until you touch real grass. ║ ║ ║ ║ Run: git-grass verify
