ssh-keys
Capabilities
- Generate keypair (RSA / Ed25519 / ECDSA)
- Deploy public key to target
Safety gate
- Private key stays only in local file / PEM field, never written to remote plaintext logs

EXECUTION (real engine)
Public key deploy via file-write (write authorized_keys) + shell-exec (reload sshd).
opsctl file-write --host web1 --path /home/u/.ssh/authorized_keys --content "$(cat id_ed25519.pub)" --mode 600
opsctl shell-exec --host web1 --cmd "systemctl reload sshd" --mode auto⚠️ Before a working public key is deployed, never run PasswordAuthentication no (it locks you out).
The engine cannot verify whether the public key is already effective; it only warns on PasswordAuthentication no — the deploy order is the operator's responsibility.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

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.
