Comprehensive toolkit for validating, linting, and optimizing bash and shell scripts. Use this skill when working with shell scripts (.sh, .bash), validating script syntax, detecting unquoted variables, checking POSIX compliance, identifying unsafe command substitutions, validating shebang lines, finding security vulnerabilities, or debugging shell script problems.
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 Script Validator ## Mindset Treat a clean ShellCheck run as the floor, never the ceiling, of validation. ShellCheck is a static analyzer: it never executes the script, so it cannot catch a missing file, a wrong permission, or an exit code that only shows up under a real workload. Always run the script against representative inputs, in a sandbox or container, after ShellCheck passes — not instead of it. Never accept a blanket `# shellcheck disable=SCxxxx` at the top of a file; a global suppression hides every future violation of that rule, not just the one the author intended to silence. Verify the shebang matches the actual syntax used in the body before trusting either signal alone: a `#!/bin/sh` script written with bash-only syntax (`[[ ]]`, `declare -A`) will pass a naive bash-mode check and then fail silently on Alpine, BusyBox, or any strict POSIX `sh`. Check exit-code propagation explicitly — a function that swallows a real failure with `|| true` or an unconditional `exit 0` breaks `set -e` for every caller upstream of it, and that failure mode does not show up in ShellCheck's output at all. ## When to Use …

How to install
mdr add pantheon-org/tekhne/bash-script-validator@sha256:bc67cada12b3f6b7The line at the top of this page pins the label git:20260923.7852cb4, 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.
