Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bash Operations Defensive Bash for scripts that run unattended — CI steps, automation, and the `scripts/` a skill ships. The goal: a script that **fails loudly on the first problem, never corrupts state, and emits parseable output**. This is the house standard for any shell script in this repo. The script contract below is the same one enforced by [`docs/SKILL-RESOURCE-PROTOCOL.md`](../../docs/SKILL-RESOURCE-PROTOCOL.md) §2–§7 — that protocol governs every skill resource, and its rules *are* bash rules. Treat the two as one standard: the resource protocol decides **what** a skill script must guarantee (streams, exit codes, help block); this skill teaches **how** to write the Bash that delivers it. The canonical reference implementation is [`skills/supply-chain-defense/scripts/preinstall-check.sh`](../supply-chain-defense/scripts/preinstall-check.sh) — read it whenever you need a worked example of every rule here applied at once. ## Bash vs Python — choose before you write Reach for Python (and the `python-cli-ops` skill) when a script grows past **~100 lines**, needs **data structures** (nested maps, JSON manipulation beyond a …

How to install
mdr add 0xdarkmatter/claude-mods/bash-ops@sha256:bb4c0f6300ab3aafThe line at the top of this page pins the label git:20260610.14f65e6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
