The Agent Skills Directory

[SAFE]: The skill is a comprehensive educational and tooling resource for shell script hardening. It includes detailed markdown documentation on dialect portability, error semantics, filesystem safety, and input construction.
[SAFE]: The provided example scripts (atomic-replace.sh, safe-cli.sh, supervise-jobs.sh) demonstrate secure coding patterns, such as using umask for temporary files, properly quoting variables to prevent word splitting/globbing, and using -- to prevent option injection.
[SAFE]: The validation script (scripts/validate-examples.sh) performs static analysis using shellcheck and shfmt and runs behavioral tests inside isolated, read-only Docker containers with no network access, which is a highly secure practice for testing potentially destructive shell code.
[SAFE]: No malicious patterns such as prompt injection, unauthorized data exfiltration, or obfuscation were detected. All external references point to official GNU and POSIX documentation.
