## What it is
Shellharden is a Rust CLI tool that syntax-highlights bash scripts and semi-automatically rewrites them to ShellCheck conformance, mainly by fixing quoting. It can display suggested changes with colored diff-like highlighting or apply them via a --transform mode.

## Use cases
- fix unquoted variable expansions in bash scripts
- highlight bash syntax in the terminal
- automatically apply ShellCheck-style quoting fixes
- audit shell scripts for unsafe quoting
- rewrite legacy shell scripts to be safer

## When to choose
- you want to automatically fix quoting issues that ShellCheck only reports
- you need terminal syntax highlighting for bash with suggested corrections
- you maintain many shell scripts and want semi-automated hardening

## When to avoid
- you need full ShellCheck lint coverage rather than quoting-focused fixes
- your scripts intentionally depend on unquoted word-splitting behavior
- you need linting for POSIX sh or other shells beyond bash
