bash

Bash and POSIX shell scripting judgment for reusable scripts, automation, CLI wrappers, dotfiles, and CI: interpreter boundaries, status propagation, quoting, globs, temporary resources, portability, style, and validation. Use only when producing or materially revising substantive Bash or POSIX shell code. Do not activate for routine technical Q&A, repository browsing, read-only inspection, tool use, one-off commands, file types, fenced examples, or incidental shell mentions.
