Why is variable quoting emphasized in this skill?

Always quoting variables prevents word splitting and globbing, which are frequent sources of bugs and security vulnerabilities, especially when dealing with file paths containing spaces.

What is Bash Strict Mode?

Bash Strict Mode uses 'set -Eeuo pipefail' to ensure scripts exit immediately when a command fails, an unset variable is referenced, or a command in a pipeline fails.

How does this skill improve CI/CD pipelines?

It provides patterns for error trapping and structured logging, ensuring that deployment scripts fail safely and provide clear diagnostics instead of continuing in an inconsistent state.

What does idempotency mean for shell scripts?

Idempotency ensures that running a script multiple times results in the same state without causing errors, such as checking if a directory exists before attempting to create it.
