70 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Baseline-harden a Debian or Ubuntu VPS in roughly thirty minutes. Covers SSH key-only authentication, UFW firewall, fail2ban with web-app jails, unattended security upgrades, kernel sysctls, journalctl retention, and sudo policy. Invoke when provisioning a new VPS, inheriting one without documented hardening, or before exposing a service to the public internet.

Works with any agent that supports SKILL.md skills.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'vps-hardening' ~/.claude/skills/'vps-hardening' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
