Generate or change idiomatic minimal Bash and Python scripts that use bzfs and bzfs_jobrunner for ZFS snapshot management workflows in a sandboxed test VM: snapshot creation, replication/backup, restore rehearsal, snapshot pruning, snapshot monitoring, and snapshot list comparison. Use when asked to create or change ad hoc/manual or periodic/automatic scripts for these tasks. Do not use this skill for general ZFS administration or non-bzfs tooling.
Improve code coverage in this repository with project-approved coverage commands and meaningful test additions. Use when asked to increase coverage, identify uncovered branches/functions, or report before-vs-after coverage percentages.
