The skill mostly does what its README and SKILL.md say (disk checks + cache cleanup across servers), but there are notable mismatches and risky behaviors — hard-coded remote IPs, root SSH usage with host-key checking disabled, and claims (like automatic backups) that are not implemented — so review carefully before running it on real systems.
评估建议
This skill largely implements its stated maintenance tasks, but has a few red flags you should address before running it on production systems: 1) Inspect and edit servers.json and maintain-all.sh: both contain hard-coded remote IPs. Remove or replace them with only servers you control. The bundled maintain-all.sh currently will attempt SSH to those addresses. 2) Root SSH & host-key checking: scripts use ssh root@host and maintain-all.sh sets StrictHostKeyChecking=no. That bypasses host authent...

ℹ 用途与能力
The scripts (check.sh, cleanup.sh, maintain-all.sh) implement disk checks, cache cleanup and multi-server SSH operations that match the described purpose. Minor inconsistency: registry metadata lists no required binaries, but SKILL.md lists dependencies (bash, ssh, du, df, npm). Functionality generally aligns with the stated purpose.
⚠ 指令范围
The runtime instructions and scripts will operate as root (ssh root@host and inspect /root), run remote commands, and remove cached directories. The SKILL.md promises safety measures (backups, only cleaning safe caches, dry-run) but the scripts do not implement a pre-operation backup step and only partially implement dry-run behavior. maintain-all.sh directly attempts SSH to hard-coded IPs; check.sh and cleanup.sh inspect /root and other privileged locations. These behaviors expand scope to high-privilege host-level operations.
✓ 安装机制
No install spec (instruction-only skill with bundled scripts). Nothing is downloaded or executed from external URLs during install — lower install-time risk. The presence of local script files means code will run on the host when invoked.
⚠ 凭证需求
No environment variables or credentials are declared, but the scripts require SSH access as root to remote hosts. The skill ships with a servers.json and maintain-all.sh hard-coded with external IP addresses (43.163.225.27 and 43.167.192.145). maintain-all.sh disables StrictHostKeyChecking (ssh -o StrictHostKeyChecking=no) which weakens host authenticity checks. Asking for root SSH access and embedding remote IPs without clearly asking the user to confirm them is disproportionate and risky.
✓ 持久化与权限
The skill is not always-enabled and is user-invocable. It does not request persistent platform privileges or modify other skills. Autonomous invocation is allowed (default), which is normal — combine that with the high-privilege SSH actions in other dimensions when deciding whether to enable autonomous runs.
