AI repos decay fast—deps drift, artifacts bloat Git, notebooks swell, and reproducibility/security slip. This guide codifies maintenance with Bash: install git/git-lfs/jq/python/pipx (apt/dnf/zypper); pin envs with pip-tools; manage weights/data via Git LFS + DVC and prune (git lfs prune, dvc gc); enforce hygiene with pre-commit/nbstripout; add smoke/data/security (bandit) checks; and schedule weekly cleanups via systemd timers or cron.
