Master defensive Bash programming techniques for production-grade scripts
by wshobsonFree
Description
bash-defensive-patterns is an agent skill from the wshobson/agents collection for writing production-grade Bash scripts. It collects defensive programming techniques: error handling, careful handling of variables and input, and safety practices that prevent the common pitfalls that cause shell scripts to fail quietly or do the wrong thing. The goal is reliability for scripts that matter, including automation scripts, CI/CD pipeline steps, deployment helpers, system administration utilities and shell libraries that many scripts share. The skill also covers the logging and monitoring that make a script's behavior visible, and it helps scripts that must handle edge cases safely, such as unusual file names or missing inputs. The detailed patterns and worked examples sit in a separate reference file, which the agent reads when the main guidance is not enough. The skill is useful when writing new scripts or hardening existing ones. It is installed with the skills CLI from the wshobson/agents repository, and its skills.sh page showed about 13.0K installs and passing results from three security audits at the time of the scan.…
