This is a local OpenClaw security tool with no external data transfer shown, but it handles real credentials and understates where those secrets are saved or persisted.
Install only if you are comfortable with a local Python tool reading and modifying your OpenClaw configuration. Before running harden.py, understand that ~/.openclaw/.env, security-backups, and persistent environment settings may contain real secrets; keep those files out of source control and synced folders, restrict permissions, review generated scripts before running them, and rotate credentials if any generated files are exposed.
