j-host-ops

name	j-host-ops
description	Plan and guide host-machine operations that must be run manually outside this devcontainer. Use when the task targets local/remote hosts (not the current workspace container), especially SSH/mosh/tmux/terminal/network setup.

/j-host-ops

Use this skill when work must happen on real hosts instead of inside this container.

Host Labels

• tux = laptop/client machine
• berghome = home/server machine

Always group commands by these labels.

Rules

1. Do not run host-changing commands from this container.
2. Provide copy-paste commands for tux, berghome, or both.
3. Include verify steps and expected output for each phase.
4. Include rollback steps for anything stateful (services, packages, firewall, config).
5. Keep steps short and linear.

Output Format

Use this structure:

1. Goal (one sentence)
2. Preconditions
3. Steps
   • tux commands
   • berghome commands
4. Verify
5. Rollback
6. What to report back (specific command outputs to paste)

Default Safety

• Prefer reversible changes.
• Prefer scoped exposure (for example Tailscale-only binds/firewall rules).
• Call out privilege level (sudo vs user) explicitly.
• If uncertain about host state, ask for command output before the next step.
