Run shellcheck -x over every shipped and dev shell script, flag bash-4/GNU-only constructs, verify env-bash shebangs, and check that each install.sh has the Git-Bash-on-Windows guard. Use to validate cross-platform portability (macOS bash 3.2 / BSD / Windows Git Bash).

Sweep the marketplace for portability hazards across the three targets: macOS
Sweep the marketplace for portability hazards across the three targets: macOS (bash 3.2 / BSD coreutils), Linux, and Windows Git Bash.
Read ${CLAUDE_PLUGIN_ROOT}/knowledge/marketplace-conventions.md (§4).
Run the sweep. bash scripts/portability-check.sh — verifies every
*.sh has a #!/usr/bin/env bash shebang and runs shellcheck -x -S warning.
bash 3.2 hazards. Beyond shellcheck, grep shipped + dev scripts for
constructs that break on macOS's bash 3.2 and report each hit:
mapfile, readarray, declare -A, ${var,,} / ${var^^}, wait -n,
and bare "${arr[@]}" under set -u (use ${arr[@]+"${arr[@]}"}).
BSD-vs-GNU hazards. Grep for readlink -f, sed -i (without backup
arg), date +%N, stat -c, find -printf, timeout, base64 -w; flag
each as needing a guard or fallback.
install.sh guards. For each plugins/*/install.sh, confirm it detects
Windows-without-Git-Bash (a uname -s case matching MINGW*/MSYS*/CYGWIN*
vs native Windows) and tells the user to install Git Bash.
Report. List every hit with file:line and the portable replacement. Offer to apply fixes.
