Nutstore WebDAV Storage

使用坚果云 WebDAV 为 OpenClaw 多 agent 工作区做备份、归档与恢复的 skill。默认按 agent 备份身份信息文件与 memory 目录；如有明确要求，也支持自定义文件或目录备份到坚果云，并保留默认排除敏感文件的执行规则。

What to check before installing / running: 1) Confirm you have bash and rclone installed on the host where you will run these scripts — the scripts exit if rclone is absent, but the skill metadata didn't declare this dependency. 2) Configure the Nutstore remote interactively (rclone config) where possible; avoid embedding credentials in scripts or long-lived shell history. If you must automate rclone config, put credentials into a secure secrets store and prefer ephemeral environment variables, not checked-in files. 3) Run the flow with dry-run (NUTSTORE_DRY_RUN=1) and test restores to a temporary RESTORE_TARGET_ROOT before enabling cron. 4) Review the scripts yourself (they are included) — they appear to enforce relative-path safety checks and exclude common sensitive directories, but verify the exclusion list matches your environment (e.g., custom secret file names). 5) If you plan non-interactive setup, note the docs show NUTSTORE_USER/NUTSTORE_PASS — these are not declared in registry metadata; handle them securely. 6) If you need the registry metadata to be accurate (for automation or policy auditing), ask the publisher to declare rclone and the optional env vars in requires.env or update the manifest so integrators know the prerequisites.
