The request "config-hardener" names no specific product, and none of the candidate sources describes a tool that hardens configuration files directly. The closest matches are GitHub's github-actions-hardening reviewer for workflow security 12, Anthropic's /modernize-harden slash command 11, and Cloudflare's configuration-patching actions for app and scan configs 16. Which configuration (e.g. GitHub Actions, cloud infrastructure, app settings) needs hardening is not stated.
A question back: Which configuration do you want to harden: GitHub Actions workflows, cloud or infrastructure settings, or application config files?
