Server base settings (SSH auth mode, timezone/hostname, file handles and caches). Use when: adjusting sshd auth, system params, kernel, or file caches. Boundary: deploy keys before changing auth (avoid lockout); reboot/shutdown are hard-blocked.

The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

Run system-setting commands via shell-exec (hostname/timezone/swap/kernel params).
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Capabilities
- Switch SSH auth mode (
PasswordAuthenticationchange goes through warnlist confirmation) - Generate SSH keys (RSA/Ed25519/ECDSA) and deploy (via file-write + shell-exec)
- File cache / timezone / hostname and other system params
- ⚠️ Reboot (reboot/shutdown) is hard-blocked and cannot run via opsctl; log in manually if you need it
Safety gate
reboot/shutdownhard-blocked (prevent accidental reboot locking the session)- Confirm key is in place before disabling password auth (avoid lockout;
PasswordAuthentication noneeds--mode yes) - Audit system changes
EXECUTION (real engine)
Run system-setting commands via shell-exec (hostname/timezone/swap/kernel params).
opsctl shell-exec --host web1 --cmd "timedatectl set-timezone Asia/Shanghai" --mode yes
opsctl shell-exec --host web1 --cmd "hostnamectl set-hostname web1" --mode yesTimezone / hostname are allowed by default; warn class like sysctl -w, PasswordAuthentication no needs --mode yes.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
