Shell Scripting

Claude Code: /plugin marketplace add wshobson/agents → /plugin install shell-scripting@claude-code-workflows

Contributed by a different author than the rest of this marketplace, and split into two agents on purpose. The bash agent starts from set -Eeuo pipefail with trap-based cleanup and mktemp handling. The POSIX agent works under a written constraint list: no arrays, no double-bracket tests, no process substitution, no brace expansion, no local keyword, no pattern substitution, and it notes that pipefail does not exist in POSIX at all, so strictness stops at set -eu. Keeping the two apart is what prevents bash-only idioms from ending up under a bin/sh shebang. Three skills carry the tooling: ShellCheck configured for the right dialect, and Bats tests asserting on status and output.
